Using r-debug.php

Since the video has been made (https://teamtreehouse.com/library/wordpress-hooks-actions-and-filters/an-overview-of-hooks-in-wordpress/working-with-wpfilter), the provided functions from Rars.net have been updated and appended in r-debug.php. And I have tried to update accordingly.

functions.php:

<?php 

require_once('examples/list_hooks.php');

?>

list_hooks.php:

<?php

    require_once( 'r-debug.php' );
    list_hooks();

?>

The site return: "Fatal error: Call to undefined function list_hooks() in /Applications/MAMP/htdocs/hooks/wp-content/themes/wp-hooks/examples/list_hooks.php on line 4"

Although r-debug.php provide this function on line 105:

<?php
    static function list_hooks( $filter = false )
?>

I know that it has been mentioned that we shouldn't follow this video along. But I'm anyway curious about why the error message appear anyway.

Thank you!

Hi Alexander,

Did you instantiate the R_Debug() class? If not, in your list_hooks.php try the following:-

<?php

    require_once( 'r-debug.php' );
    $r_debug_object = new R_Debug();
    $r_debug_object->list_hooks();

?>

Hope this helps, Jon
