This is a pretty broad question, but I will still try to answer it. WordPress is a mature platform so you won’t see many changes between 3.5 and the current version that would require you to learn from scratch. The basics of WordPress are still the same with some additional features that will make your … Read more
When dealing with submit forms, even if they are sent with AJAX, you must play by the Never trust user’s input rule. Every data-attribute can be changed, edited via Inspector. Your only trusted validation should be on the server side, as you did with: if ( isset($_POST[‘author_id’]) || is_numeric($_POST[‘author_id’]) ) Personally, I would inverse the … Read more

You must use wp_delete_post() with second parameter set to true. The post will be completely deleted, not trashed. // Use $args to get the pages you created previously // See https://developer.wordpress.org/reference/functions/get_pages/ $pages = get_pages( $args ); if( $pages ) { foreach( $pages as $page ) { wp_delete_post( $page->ID, true ); } } After that, you … Read more
There is no safe way to do that, and even if you succeed, you will cause a lot of trouble for your users. The root directory for the web site is $_SERVER[‘DOCUMENT_ROOT’]. You might not have write access here, because that can, and maybe should, be turned off. WordPress might be installed in a subdirectory; … Read more

As soon as its output once by admin_notices it will be cleared. /** * Sample_Notice_Handling */ class Sample_Notice_Handling { public static $_notices = array(); /** * Constructor */ public function __construct() { add_action( ‘admin_notices’, array( $this, … Read more
