I have seen and been using the following technique for adding php scripts to my plugin for handling custom forms in a wordpress plugin.

from the quizzin plugin:

```
$code_pages = array('quiz_form.php','quiz_action.php', 'question_form.php', 'question.php');
        foreach($code_pages as $code_page) {
            $hookname = get_plugin_page_hookname("quizzin/$code_page", '' );
            $_registered_pages[$hookname] = true;

```

For example, the 'quiz\_action.php' is later used as the target for an administration form (these forms are used only in wp-admin)

```
  <form name="post" action="<?php echo $GLOBALS['my_plugin_folder'] ?>/quiz_action.php" method="post" id="post">

```

**UPDATE:** This method is discussed here - [Admin config screen without menu](https://wordpress.stackexchange.com/questions/1778/admin-config-screen-without-menu/1812#1812)

The final comment below by a Wordpress core dev seems to discourage this:

<http://wordpress.org/support/topic/how-can-i-execute-php-scripts-in-my-plugin-folder>

So what is best practice here? Should administration forms be posting to wp-admin/admin.php?action=foo or wp-admin/edit.php?action=bar. How does one register these actions? Is this documented anywhere? To be clear, these files should not be linked from an admin menu.

I'm using Wordpress 3.0.4

Thanks!
