Extending Admin Class Error

[somweb]

I wrote a theme where I extended the Admin class successfully. Doing it now for a plugin, I am getting the following error on the first line of the new extended class:

class UVASOMNAVBAR_Settings extends Genesis_Admin_Boxes {

When in debug mode, here is the error I get on the line above:

Fatal error: Class 'Genesis_Admin_Boxes' not found

I am running Genesis 1.9 and am installing the plugin on the child theme where I also extended the class. On the child theme, the name of the new child class is different, so I know it's not conflicting.

So, my question is, do you use a different class or syntax if you are extending the admin class in a plugin rather than in a child theme?

Plugins get set up by WP before themes do, so at the moment your plugin runs and the class gets parsed, none of the Genesis_Admin_* classes exist.

What you need to do is to put your class into a different file, then wrap a function around the require() call, which is hooked into genesis_admin_init. You'll see that hook fires at the end of genesis/lib/classes/admin.php.

// my-plugin/class-uvasomnavbar.php

class UVASOMNAVBAR_Settings extends Genesis_Admin_Boxes {
...
}

// my-plugin/my-plugin.php

add_action( 'genesis_admin_init', 'myplugin_admin_init' );
/**
 * Include admin class, now Genesis admin classes exist, then instantiate it.
 */
function myplugin_admin_init() {
    require( 'path/to/class-uvasomnavbar.php' );
    new UVASOMNAVBAR_Settings();
}
