Merge Tags For WordPress Posts & Pages

Here are the merge-tags that you can use in your WP posts, and what they mean. (Click here for merge tags for Autoresponder & Broadcast Emails)

[DAPLoginForm]

This is better suited for a WP “page”. This text will be replaced by a login form using which your members can log in to your membership site.

%%AFFDETAILS%%

This will be replaced by the entire Affiliate section from the default home page at YourSite.com/dap/ . Better suited for a Page.

[DAPUserProfile]

This will be replaced by the user profile from the default home page at YourSite.com/dap/. Better suited for a Page.

[DAPMyContent]

This will be replaced by the user links section (the list of what products and what links user currently has access to) from the default home page at YourSite.com/dap/. Better suited for a Page.

%%FIRST_NAME%%

This will be replaced by the first-name of the user.

%%EMAIL%%

This will be replaced by the email id of the user.

%%AFF_LINK%%

This will be replaced by the raw affiliate link of the member. If you want it to show up as a link in your blog post, use it like this:

<a href=”%%AFF_LINK%%”>%%AFF_LINK%%</a>

%%USER_NAME%%

This will display the DAP user’s “Username” on the page.

%%USER_ID%%

This will display the DAP user’s ID on the page (ID is a number).

%%FEEDLINK%%

Replaces with user’s personalized RSS feed URL.

%%PRODUCT_DETAILS_<insert-product-id>%%

Replaces merge tag with Product-specific details (including links available to the member as part of that Product) on a specific WordPress page/post.

%%DAPCUSTOMFIELD_<insert-custom-field-name>%%

You can display the value of the user’s own custom fields on your pages, using a merge tag like this:

%%DAPCUSTOMFIELD_tax_id%%

In the above example, tax_id is the custom field that you have created in DAP. So if the name of the custom field in DAP were “ssn”, then the above merge tag would become %%DAPCUSTOMFIELD_ssn%%

[DAPUpline]

Displays data of the user’s “upline” affiliate.

[DAPComingSoon]

Displays upcoming drip-feed scheduled content.

[DAPRefAffId]

Displays id of affiliate who referred visitor to site. If no affiliate set, displays DAP Admin’s id.

Login/Logout Widget

DAP has a Login/Logout Widget that you can use in any widget-ready theme.

Log in as WP admin, and look under “Appearance > Widgets”.

You’ll see the widget. Drag this widget on to any customizable part of your theme.

The widget puts the DAP login form right on your sidebar.

When a user is not logged in, they will see the login form.

When they are logged in, they just see a “Logout” button.

DAP’s Incredibly Powerful Affiliate Program

DAP offers you a built-in Affiliate Program for your web site, where all your Members can automatically and instantly be enrolled as Affiliates.

And here are a few, rare and powerful features in DAP, that you won’t find in most other affiliate providers:

1) Instant Affiliates

This means that as soon as a buyer purchases any product, or even signs up for a free product, they can get an instant affiliate link that they can immediately start using to promote your membership site.

In fact, you can even send them their own unique affiliate link right in their welcome email itself, the same email where you send them their login info! So even before they’ve logged in to your site to download or view the content that they’ve just purchased, they’re already and affiliate and can start promoting your site to others, and earn back their investment even before they’ve reached your refund period.

2) Global Affiliate Link

There’s just one “core” (default) affiliate link that your affiliates can use to promote your web site, and regardless of which product the referral ends up buying, your affiliate gets paid on all of those purchased products.

So it’s like an Amazon affiliate link. One global link that gets you paid on any resulting purchases. So your specific affiliate link could be promoting a book, electronic gadget, shoe or clothing. And once your referral gets to Amazon.com after clicking your affiliate link, even if they don’t purchase that specific product that you just them to, and go on to purchase ANY other product from the entire Amazon.com catalog (which are commission-eligible, of course), then you’ll make commissions on any resulting sale. That’s exactly how the DAP affiliate program works too. Just one default affiliate link. Affiliate can redirect visitor to any landing page (see details below), and affiliate gets paid for any resulting sales.

3) Affiliate Link Redirection

Let’s say you were an Affiliate of Amazon.com. Now imagine if Amazon gave you just one, static affiliate link to promote ALL of their products across their ENTIRE web site. That is, one standard affiliate link to promote millions of products, and anyone who clicked on that standard link would always land at Amazon’s home page, no matter what – and that there was no way to direct affiliate traffic directly to any of the actual product pages.

Imagine if you saw a link on our blog that read “Click here to check out the amazing Bamboo Fun tablet” and the link, instead of taking you directly to the product page of the Bamboo fun, took you to Amazon’s home page? How incredibly annoying would that be for the visitor to always be taken to Amazon’s home page no matter what product someone were recommending? Think Amazon would be the e-commerce juggernaut it is today without that implementing that simple feature?

But Amazon lets you link directly to the product pages of the product you are referring to (or recommending, or promoting).

Like….

“Check out the amazing Bamboo Fun tablet” (links directly to product page)

“Check out my best-selling book ‘No Business Like E-Business’ on Amazon” (links directly to the book page)

We are amazed that so many affiliate software providers do not offer this simple, basic feature. And that is the ability to set the affiliate cookie, and then redirect the referred visitor to any page on any web site the affiliate wants the visitor to land on.

So when you use DAP, your affiliates are not forced to always send traffic to your home page. They can redirect the visitor (who just clicked on their affiliate link) to any part of your web site. In fact, they can redirect the visitor to any web page on any web site anywhere online! So they could be sending traffic to one of your free videos, one of your blog posts, or even to one of your articles published on someone else’s web site!

3) Multi-Tier Affiliate Program

DAP allows you to offer multiple tiers of commissions, not just one. So you can create an incredible revenue stream for your affiliates, where they get paid on the sales generated by their 1st level referrals. Which means more incentive for them to join and promote your affiliate program!

4) Paying A Per-Lead Commission To Your ClickBank Affiliates

You already know that DAP supports ClickBank purchases, and you can turn off the display of your affiliate section if you are using ClickBank’s own affiliate program, instead of DAP.

But wait – that does not mean that you can’t use the two affiliate programs IN TANDEM to pull of something really crazy – like awarding your ClickBank affiliates with a commission just for sending you a lead – meaning, the lead just signs up for your “free” newsletter – and of course, if they go on to purchase something from your web site (assuming you are selling through ClickBank), then they get the usual CB commissions.

So here’s how it works:

• Every member on your DAP-powered site gets their own affiliate link that looks like:
  http://YourSite.com/dap/a/?a=1234
• And their CB affiliate link for your product would look like
  http://affnick.merchantnick.hop.clickbank.net
• Now DAP’s affiliate link has the capability of redirecting to any page on your site (or any page on any web site) by adding the destination URL to the affiliate link.
• So, now your affiliate adds their CB affiliate link to the END of their DAP affiliate link, like this:
  http://YourSite.com/dap/a/?a=1234&p=http://affnick.merchantnick.hop.clickbank.net
• So when someone clicks on this above link that your affiliate is promoting, then two things happen:
  a) The DAP affiliate cookie is set
  b) The CB cookie is also set
• So within DAP, you can set up just a Per-Lead Affiliate Commission for your Product (which is say, a free newsletter or a free PDF, or whatever)
• So when the referred user signs up at your membership site, they first get paid the Per-Lead Commission
• If they then go on to purchase other products from your web site (which obviously you’re selling through ClickBank, otherwise, this whole section is of no meaning to you), then they get the Per-Sale commission from ClickBank too!

So that sums up some of the best features that are part of DAP.

Other Built-In Affiliate Features

Of course, there’s still all the other cool affiliate features in DAP, like…

• Commission Override: Give special treatment to your Top Affiliates and JV partners by giving them higher commissions than the rest of your affiliates.
• Pay affiliates both one-time or monthly recurring commissions for the life of the subscriber.
• Pay-Per-Lead and Pay-Per-Sale
• Ready-made Affiliate Links Displayed for Users
• Ready-made Affiliate Toolbox for your affiliates
• Affiliate-Analytics:
  * Real-time Earnings Reporting
  * Real-time Payment Report
  * Real-time Traffic Stats for both Affiliates and Admin (with referers)
• Paypal Mass-Pay Ready: You get a Paypal Mass-Pay ready, fully formatted affiliate list with all commissions listed.
• Offline Payments: Export Affiliates for payment, pay them using any offline means (eg., checks), and then once the checks have been mailed, you can mark them all as “Paid”.
• Process Refund for Affiliates: When you process a refund, DAP will also reverse the affiliate commission. It will not reverse the Pay-per-lead amounts. Only the Pay-per-sale amount is negated.

So these are the features available to right out-of-the-box, just waiting for you to start signing up an army of affiliates from day 1!

How Do Members Get Added To Your Membership Site

(OR) How do members get access to the content

(OR) How does someone become a member?

With DAP, you can add users to your membership site in 3 different ways.

1.  PURCHASE: Someone buys your product or subscribes (“Paid” member with access to both free and paid content)

2.  FORM SIGNUP: Someone signs up through a signup form (“Free” members with access to only free content)

3. ADMIN ADDED: You add them as a member directly through the DAP Admin Control Panel (you can mark them as either “free” or “paid”)

All three are explained in detail below.

1. PURCHASE

*You first create a “Sales Page”.

On your sales page, depending on which payment processor you use, you go to Paypal/1ShoppingCart/ClickBank and create a new product with the EXACT same name as the product you created within DAP, and get the ‘Buy Button’ link from your Payment Processor. Publish this “Buy Button” on your sales page.

* Your visitor goes to your sales page

* They purchase your product

* Your payment process (Paypal/1ShoppingCart/ClickBank) notifies DAP that you have a new purchase.

* If the product names match, DAP automatically creates an account for them, generates a random password, and sends them an email with their email/password. You can customize the contents of this email on the “Templates” screen in your DAP Admin Control Panel. Integration with your shopping cart explained elsewhere (see documentation for setup).

That’s it!

That’s how “buyers” get added to your membership site and get access to the product they just purchased.

2.  FORM SIGNUP:

You wish to give someone a “Free” membership.

NOTE: “Free” members who do not have a payment associated in DAP (which means they have not purchased anything) will have access only to content that you have marked as “Free”.

Once you have created a Product in DAP, and have added content (blog post/page links, links to files, etc), and have saved it, on the Product page, below the Product name list, you will see a link called “Direct Signup HTML”. (See image below). You must first select a Product before you can copy the correct form HTML.

Fig 1. Direct Signup Link on Products page

Fig 2. Form HTML that you get on clicking the Direct Signup Link

This HTML gives you the full HTML form code that you can publish on any page of your web site. This form only collects an email address and a first name.

Take this HTML code and publish it on page of your web site where you want sign up users. This could be a WP page or post too.

Note: When you see the above HTML code, there’s a field in there that looks like this:

<input type=”hidden” name=”redirect” value=”http://YourSite/Your-login-page-link/?msg=Success!%20Your%20membership account%20has%20been%20created.%20%20Check%20your%20email%20address%20in%20a%20few%20minutes%20for%20your%20password“>

Don’t forget to change the text above, where it says “http://YourSite/Your-login-page-link/?…” to point to your actual domain name and to your actual login page (if you have customized it).

Then, when someone enters their email address and first name and signs up through the signup form, DAP creates an account for them using that email address, creates a random password, and sends them an email with their email/password.

After that, you can drip any content or emails on them that are marked as “Free” (when adding content or emails).

At some later point, if they purchase any of your “Paid” products (see the “1. Purchase” section above), then as long as they use the same email id during purchase, DAP will automatically give them access to all of the “Paid” content in the Product that they just purchased.

3. ADMIN ADDED:

If you wish to directly give someone access to a Product and all its content and emails, you can add them directly from the DAP Admin screen (Users > Add/Edit).

You just need their email id and their first name (both of which they can change subsequently) to add them to a Product.

While adding them, you have the option of marking them as a “Paid” user by checking the “Mark as Paid” checkbox.

If you don’t check this check box, then they will be added as a “Free” user and get access only to “Free” resources (content/emails).

But if you check the “Mark as Paid” checkbox, then they will get access to all “Paid” content and emails, just like someone who is actually a “Paid” member.

Logout Link

Login/Logout Widget

If you are using the DAP Login/Logout widget on your sidebar, then the login widget automatically turns in to a “Logout” button once a member has logged in. No separate link needed if you’re using this widget. Click here to read more about the Login/Logout widget.

Logout link in your Menu

If you have a custom menu (WP Admin > Appearance > Menus), then you can add a custom link that points to “/dap/logout.php” or “http://YourSite.com/dap/logout.php” to your menu. This link will log your users out of both DAP and WordPress.

 

Default DAP Member Page

If you use the default member’s area that comes with DAP out of the box – http://YourSite.com/dap/ – then this page already has a “Log out” link at the top.

But if you are putting all of DAP’s member pages within your WordPress blog using our various shortcodes, then you need to publish the DAP logout link in your sidebar (or wherever you choose to).

Here’s the link for logging out of the member’s area:

http://YourSite.com/dap/logout.php

Replace “YourSite.com” with your actual site name, of course. And then publish the above link anywhere on your blog – sidebar, top menu bar, etc.

 

NOTE: Clicking on the DAP log out link will log you out of both DAP and WordPress.

Protecting Files

DAP File Protection

DAP is one of the few membership plugins that can protect all kinds of web site files on your web site. But this feature comes with a few caveats. Read this page completely before you decide.

DAP can protects files “in-place” – meaning, the exact same files that will actually be accessed by your members when they’re eligible to.

Most other membership plugins resort to all sorts of “gimmicks” – like hiding the real location of the main file, cloaking it, trying to obfuscate the link, etc.

Not only is it a inefficient way of securing files, but it’s also extremely insecure.

On top of that, with other membership plugins, you cannot send protected links via email, because that would then give away the location of the true file, which they are not protecting.

DAP is among the very, very few membership plugins that protect files in place, which means even if the true location of the file is passed around by your members to their non-member friends, the file cannot be accessed without having to log in first with a valid member account that is actually eligible to access that file.

DAP provides the ultimate security for your files – and ultimate peace of mind for you – like no other plugin can, knowing that your content can never be illegally shared online with un-authorized users.

And DAP can protect any kind of file – including videos, audio, images, reports, zip files, even Javascript files – with any kind of extension: like .pdf, .doc, .zip, .jpg. .js, .mp3, .mp4, .mov., etc etc.

RECOMMENDED: Amazon S3 File Storage

Highly Recommended

The ideal and best way to store files is to store them on Amazon S3, and then use a plugin like our own S3MediaVault.com to insert secure, expiring links to those files within your WordPress pages. That way, the page itself is protected by DAP, your files on Amazon S3 are protected by the S3MediaVault plugin, and you have two layers of protection for your content.

If you decide to store your files on Amazon S3, then ignore the rest of this article, and head over to Storing files on Amazon vs your Webhost

The steps below are only useful if you are going to use all of your files on your own web hosting account – which is not ideal and is not recommended.

Section I: Protecting Files Under WordPress

This is the easiest way to protect files on your server, in DAP.

1) Upload them to your WordPress blog when you are writing a new post. All such files will be stored in a folder called “wp-content/uploads/….“.

For large files, you could simply upload them directly using FTP, directly into the “wp-content/uploads/” folder and DAP is configured right off-the-shelf to “look” for any file inside the “wp-content/uploads/” folder. But once the file is under the “wp-content/uploads/…” folder (either directly under it, or under a sub-folder, like wp-content/uploads/videos/), you will now still need to let DAP know that this file is to be protected as part of a Product.

NOTE: You DO NOT have to upload files using the WP file uploader (like some of our competitors force you to do!). You can use regular, plain ol’ FTP, using a client like FileZilla or CuteFTP, or your webhost cPanel’s FTP feature.

2) Go to the product you wish to protect the file as part of, and then scroll down to the “ContentResponder” section.

2.1) If you know (or can figure out) the full URL to your file – like http://www.YourSite.com/wp-content/uploads/coolreport.pdf – you can simply paste that directly into the field “A” (in the image below)

2.2) Or, if you can’t figure out the full URL, then you can enter “wp-content” (if your blog is directly in your root folder) – or “blog” or “members” (if your blog is not in your root, and is in a sub-folder) into field “B” below, and then click on “Load Files”, and it will show you all files under that folder. And you will be able to scroll through and look for your file. And there click on the “Add” link right next to that file name you wish to protect.

Once you do (2.1) or (2.2) above, the file will get added to the Product, and will now be protected.

Section 2: Protecting Files Outside of WordPress

This is NOT RECOMMENDED, unless you are technical and you know what you’re doing.

There is a one-time setup process involved, if you wish to protect files outside of your WordPress directory.

1. You need to add the following code to the .htaccess in the root of your web site. So, in your web site’s root folder (where you have your home page – like index.php or index.html for example)…

i) if you already have an existing .htaccess file there, then just open it, COPY the text from below and PASTE it at the very end of this file.

ii) If there is no .htaccess in your root folder, then create one, and then open it, COPY the text from below and PASTE it at the very end of this file.

NOTE: BE SURE TO MAKE A BACK-UP OF YOUR EXISTING .htaccess FILE FIRST


#Paste this at the very end of your .htaccess file
#in your web site's root folder

<IfModule mod_rewrite.c>
#dap
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} -f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !dapclient.php
RewriteCond %{REQUEST_URI} !^/dap/
RewriteCond %{REQUEST_FILENAME} !(.*)(\.php|\.css|\.js|\.jpg|\.gif|\.png|\.txt)$
RewriteRule (.*) /dap/client/website/dapclient.php?dapref=/$1&plug=wp&%{QUERY_STRING} [L] </IfModule>

 

Doing the above enables file protection for files outside your WordPress installation folders.

2) Now go to the DAP Product you wish to protect the file as part of, and then scroll down to the “ContentResponder” section. Then…

• If you know the full URL to your file – like http://www.YourSite.com/reports/coolreport.pdf – you could simply paste that directly into the field “A” from the image above (make sure you “visit” this URL first and verify that there is actually such a file at this link)
• OR… if you can’t figure out the full URL, then you can enter the text “reports” (the name of your top-level folder where your file is) into field “B” from the image above, and then click on “Load Files”, and it will show you all files under that folder. And you will be able to scroll through and look for your file. And there click on the “Add” link right next to that file name you wish to protect.

The file is then added to the Product, and will now be protected as part of that Product.

That’s it.

Testing File Protection

Open a different browser (not different window – a totally different browser – like, if you’re logged in as DAP admin in FireFox, then open IE)  and try to access your file directly and see if DAP redirects you to the login screen.

If not, take a deep breath – it’s NOT DAP 🙂

It’s just that you probably missed something during the setup.

Revisit the steps above, and if you still can’t figure it out, you might want to think about uploading the file to Amazon S3.

This feature can be hit-or-miss depending on server software, PHP version, security software on your server, etc. So if it works, then great.

If it doesn’t work, then it is specific to your server. So if you want us to log in to your site and troubleshoot this, if you are a Platinum member, we can do this for free.

And if you’re not a Platinum member, you will have to purchase a premium support slot in order for us to log in to your site and troubleshoot this.

So while you can try it and see if it works, especially if you’re protecting just a couple of ebooks and reports, if it doesn’t work, then it’s in your best interest for the long-term, to switch to Amazon S3 for hosting your premium files.

If you have a number of large files to deliver to your members, then you should consider hosting your files on Amazon S3. And here’s why…

Protecting WordPress Posts & Pages

• Log in to DAP Dashboard and go to the “Products/Lists” page.
• Select the product to which you want this blog post/page to be a part of
• Scroll down to the “ContentResponder” section
• On the left, you will see a list of blog posts & pages that have been published (if you scroll down in the window where the list of “posts” show, you will also see list of “pages”)

• Select one or more (hold Ctrl + Click to select multiple)
• Click on “Add Selected Posts/Pages” to protect the posts/pages.
• The post(s)/page(s) will now show up on the right-hand side of the box.
• Click on “edit” next to each link to configure dripping for individual posts/pages.

12

Using Sneak-Peek For Blog Posts

By default, none of the posts or pages you have protected in DAP will be visible in any of the WP menus (not even in custom menus).

Which means, as far as your visitors (or search engines) are concerned, those posts/pages don’t even exist in your blog – until the content “drips” on them.

Some DAP users want it that way, and some don’t.

Also, from an SEO perspective, if your visitor (who is not a member, and one who is not logged in) can’t even see the post, then neither can Google. This means, if you do a blog-and-ping, when Google arrives at the permalink of your new post, because the post is protected, DAP will redirect Google to your login page. This means, you don’ get the benefit of SEO for your new post.

Also, from a “Curiosity” standpoint, if you protect all of the posts, then your visitor will only see a handful of non-protected blog posts, and logged-in members will see only content that has already dripped on them (accessible to them).

Giving them a “sneak-peek” of the protected content is a great way to get them excited about your content.

So for example, you could have a blog post that talks about a video, and goes into detail about everything that they can learn from watching the video – but the content ends just before the video, and where the video would’ve normally appeared, there appears a “Login Form” that asks them to login first before they can view the content, or purchase access if they wanted to see the video.

How to turn on Sneak-Peek

Go to DAP Dashboard > Config > WordPress Sneak-Peek

It is set to “N” (no) by default. Change this to “Y” and click on the “Update” button to save the change.

And then when they click on the “more” button to read the rest of the post, the full post is protected anyway, and they are presented with a login screen.

WARNING: READ THIS BEFORE YOU TURN ON SNEAK-PEEK

As soon as you turn on Sneak-Peek, DAP will show all content from your blog posts, but only up to the “More” tag. This means, if you don’t have a “More” tag in any of your content, then all of your blog posts will show to all users, regardless of whether they have access or not.

So, the most important thing here is this:

SNEAK-PEEK and MORE are INSEPARABLE.

If you do sneak-peek, you MUST include a “More” tag.

So when you create a WordPress blog post, split the post into two parts using the “More” tag. This creates a “public preview” portion of the actual post, that shows up on your blog’s home page and in the permalink when that post is displayed. To read the rest of the post, your visitor has to click on the “More” link, and that’s when depending on whether the user has access, the rest of the post will be displayed.

Payment: Setup and Integration – FAQs

Q: I just made a test purchase. But DAP did not process the payment (or) did not add me as a member (or) is not creating a new member.

Make sure that the product name within DAP and the product name in your “buy” button (i.e., your shopping cart) are EXACTLY the same. Don’t just look at the two and say, “oh yeah, they’re the same”.We recommend “copying” the product name that you set up in DAP, and then “pasting” it when creating your “buy” button. If you are using Paypal, then this is the “Item Name” when you are creating your Paypal “buy” button. If you are using 1ShoppingCart, then this is the “Product Name” when creating a new product.

(Paypal users, skip ahead)

1ShoppingCart/ClickBank:

1) Make sure you have set up the “Email Order Processing” correctly.

2) Is your Cron Job dap-emailorder.php set up and running correctly?

3) Make sure you have not “removed” the 1Shoppingcart or ClickBank payment notification email from your server. Log in to your email server, and make sure that the email is still there, and also it needs to be “Unread”. If your email client (like Outlook or Thunderbird, or Gmail) already accessed it and marked it as read, then simply mark it unread, and the next time DAP runs (which should be in 10 minutes) it will pick up the email and process it.

Paypal Users:

1. If you are using Paypal IPN, then make sure you have enabled IPN within your Paypal account.

2. Make sure you put the correct IPN “notify_url” text in your button.

3. Make sure the Paypal button you set up is a “Buy Now” or “Subscribe” or “Add to Cart” button.
