This guide should assist some of you who are attempting to integrate a custom PHP script with aMember and to check UAC level.

The first part, is to modify your aMember plugin (custom) to allow the user to enter which products that plugin applies. This is the simplest method. For example purposes, we will use the plugin named “plugin_template”.

add_config_field(
    'protect.plugin_template.products',
    'Product ID\'s',
    'text',
    "Enter the product ID to create access for. For multiple products, use the ; (semicolon). [example: 19;21;22 ]",
    $notebook_page
);

Your script to protect the page. Please read inline comments for where to place your code.

 

And thats all there is to it. Administrators of aMember should now be able to add their products by going to aMember CP > Plugins > plugin_template by entering the product_id which shows up on the left most column of every product created. For multiple products, they would use a semicolon ( ; ) between the product id’s (these instructions are in the comment field for the new field).

Now you can focus on coding the application without worrying about the aMember integration side of things by using this code. For more advanced scenarios we are still available for custom solutions.
