Structure of a WordPress plugin

[szepeviktor]

While trying to run static analysis on OneSignal-WordPress-Plugin I've faced the structure of the plugin.

Please consider having clean class and function files.

• /inc/class-$CLASSNAME.php (only 1 class, no instantiation, no add_action)
• /inc/class-$CLASSNAME.php (only 1 class, no instantiation, no add_action)
• /inc/class-$CLASSNAME.php (only 1 class, no instantiation, no add_action)
• /inc/helpers.php <-- all - really all - functions here (only function definitions, no add_action)
• global function names like load_javascript name conflict with other plugins/WordPress core, so have a unique onesignal_ prefix in all global names
• if you have a tiny code to hook use an anonymous function

add_action(
	'admin_enqueue_scripts',
	function () {
		global $post;
 	    if ( ! $post ) {
			return;
    	}
       	wp_register_script('notice_script', plugins_url('notice.js', __FILE__), array('jquery'), '1.1', true);
        wp_enqueue_script('notice_script');
        wp_localize_script('notice_script', 'ajax_object', array('ajax_url' => admin_url('admin-ajax.php'), 'post_id' => $post->ID))
	},
	10,
	0
);
