Custom PHP Assignments

Heads up! This article contains PHP code and is intended for developers. We offer this code as a courtesy, but don’t provide support for code customizations or 3rd party development.

Custom PHP Publishing Assignments give you the opportunity to display your box for virtually any occassion you can think of. The only thing stopping you is having the PHP knowledge to code it and how far you are willing to go.

With Custom PHP Publishing Assignments you can get all the data available in the variables, URLs and even the database. Then you can do all kinds of checks on these data.

The main point of Custom PHP Publishing Assignments is that you always need to return either a TRUE or a FALSE value. For TRUE the assignment is valid and vice versa. Here’s an example:

if ($variable == 'value') {
   return true;
} else {
   return false;
}

Or written in a more compact way:

return ($some_variable == 'some value');

Below are a (growing) collection of ready-to-use PHP assignment scripts. You can also use these as examples and starting-point to create your own custom scripts.

Assign to certain (parts of) email addresses

// Comma separated list of (parts of) email addresses
$emails = '@yahoo.com,@hotmail.com';

// Do not edit below
$pass = 0;
foreach(explode(',', $emails) as $email) {
    if (!(strpos($user->email, $email) === false)) {
        $pass = 1;
        break;
    }
}
return $pass;
