Actions and Filters in MemberPress

What Are Hooks?

Hooks in WordPress allow you to change or add code without editing core files. They are used extensively throughout WordPress and MemberPress and are very useful for developers.

• Actions allow you to insert custom code wherever the hook is run
• Filters allow you to manipulate and return a variable that it passes to filter

Please note, that this is a Developer level documentation. Our support doesn't cover custom development. 
If you need any help with your customization you can contact one of the developers.

Using Hooks

If you want to use a hook to add or manipulate code, you can add your custom code in many ways:

• You can add your code at the end of your theme's functions.php file
• Use one of the plugins such as the WPCode plugin (please check this article for details: How to add custom code snippets in WPCode).

Using action hooks

To execute your own code using action hook, you need to use your custom function like this:

add_action( 'action_name', 'your_function_name' );
function your_function_name() {
    // Your code
}

Using filter hooks

To manipulate the passed variable in filter hook, you need to use your custom function like this:

add_filter( 'filter_name', 'your_function_name' );
function your_function_name( $variable ) {
    // Your code
    return $variable;
}

Keep in mind that with filters, you must return a value.
