To create a Moodle plugin with PHP and AJAX that allows the selected value in the first select box to affect the second select box, follow these steps. For example, we will create a plugin that enables users to select a course and then display a list of students enrolled in that course in the second select box.

Step 1: Create a directory for your plugin

Create a directory inside the moodle/local/ directory with your plugin’s name. For example, let’s call it “customselect.”

Step 2: Create a PHP file to handle AJAX

Inside your plugin directory, create a PHP file to handle AJAX requests. For example, name the file ajax.php and include the following code:

 

Step 3: Create a PHP file for the HTML view

In your plugin directory, create a PHP file to display the HTML view for the Moodle page. For example, name the file index.php and include the following code:


 

Step 4: Create a language file

In your plugin directory, create a language file to add strings used in the plugin. Create a PHP file with an extension like .php and name it, for example, local_customselect.php. Include the following code:

 

Step 5: Activate the plugin

Activate your plugin through the Moodle administration page.

After following these steps, you will have a Moodle plugin that allows users to select a course in the first select box and then displays a list of students enrolled in that course in the second select box using AJAX. Be sure to replace the database queries and business logic according to your needs.
