Thanks for the answers guys. Though both answers set me on the right path, none worked out of the box. So I’m sharing my solutions below. Method 1 – Using register_activation_hook: Create the Parent Plugin in plugins/parent-plugin/parent-plugin.php: <?php /* Plugin Name: Parent Plugin Description: Demo plugin with a dependent child plugin. Version: 1.0.0 */ Create … Read more

I think you have to be a little careful because it depends on what you are trying to do. If you are using a child theme get_template_directory(); will still go to the parent theme. However get_stylesheet_directory(); will go to the current theme, child or parent. Also, both these functions return absolute server paths. If you … Read more
Short answer: your name attribute values must use the schema option_name[array_key]. So, when you use … <input name=”option_name[key1]”> <input name=”option_name[key2]”> … you get an array as option value in your validation function: array ( ‘key1’ => ‘some value’, ‘key2’ => ‘some other value’ ) PHP does that for you, this is not a WordPress feature. … Read more
They are defined as follows: define( ‘ABSPATH’, dirname(dirname(__FILE__)) . “https://wordpress.stackexchange.com/” ); define( ‘WPINC’, ‘wp-includes’ ); dirname is a PHP function that returns the path of the parent directory, and wp-includes is pretty self explanatory. I would say ABSPATH is better because it’s one of the first things WP loads and it also looks better:) But … Read more
Okay, I’ll take a stab at this. Some limitations I encountered along the way: There are not a lot of filters in subclasses of WP_List_Table, at least no where we need them to be. Due to that lack of filters, we can’t really maintain an accurate list of plugin types at the top. We also … Read more

Using the CPT infrastructure has a number of notable benefits: You get the Dashboard UI for free You automatically take advantage of WP’s caching, including any persistent cache plugins that the installation may … Read more
The way to do this is to use the ‘admin_enqueue_scripts’ hook to en-queue the files you need. This hook will get passed a $hook_suffix that relates to the current page that is loaded: function my_admin_enqueue($hook_suffix) { if($hook_suffix == ‘appearance_page_theme-options’) { wp_enqueue_script(‘my-theme-settings’, get_template_directory_uri() . ‘/js/theme-settings.js’, array(‘jquery’)); wp_enqueue_style(‘my-theme-settings’, get_template_directory_uri() . ‘/styles/theme-settings.css’); ?> <script type=”text/javascript”> //<![CDATA[ var template_directory … Read more
the “safer and cleaner” way would be to use admin-ajax.php that comes with wordpress and wp_ajax hook to call your processing function from your plugin file and use wp-nonce to check the integrity of the call. for example: your ajax JQuery call would be <script type=”text/javascript” > jQuery(document).ready(function($) { var data = { action: ‘ACTION_NAME’, … Read more
Note that plugins are all “controllers” by WP standards. It depends on what the plugin is supposed to do, but in all cases I would try to separate the screen output from the PHP code as much as possible. Here’s one way to do that easily – first, define a function that loads the template: … Read more
