WordPress is old. In fact, it is older than PHP7, in which PHP introduced random_int(). WP wanted/needed this functionality before, so another method was implemented. how does the PHP interpreter understand which of the two functions I’m calling? Good question. The interpreter doesn’t understand this. And hence, if you had PHP7 and would define this … Read more
the_permalink echos out the permalink of the current post to the frontend. get_permalink however returns it as a variable, but does not echo it out. You can also pass a post ID to it if you want the permalink of another post. the_permalink is equivalent to: echo get_permalink(); Which is very close to what it … Read more
The file wp-admin/includes/plugin.php is not always included. You may have to do this in your plugin. And your Location header is invalid: You have to send a complete URL. You should use: require_once( ABSPATH . ‘wp-admin/includes/plugin.php’ ); When do you call this function? Maybe too early.
This should work: add_action( ‘woocommerce_init’, ‘remove_wcpgsk_email_order_table’ ); function remove_wcpgsk_email_order_table() { global $wcpgsk; remove_action( ‘woocommerce_email_after_order_table’, array( $wcpgsk, ‘wcpgsk_email_after_order_table’ ) ); }
Use a custom walker, extend the methods start_lvl() and end_lvl.

The page ID (or object ID, since a menu item can link to any object) is stored in the postmeta table, with the key _menu_item_object_id. So you can get the page ID with the following code: get_post_meta( $item->ID, ‘_menu_item_object_id’, true );
Your above function tests whether a page is a child page of some other page, not whether it has children. You can test for children of the current page like so: function has_children() { global $post; $children = get_pages( array( ‘child_of’ => $post->ID ) ); if( count( $children ) == 0 ) { return false; … Read more

That is why one should actually always unset that value after the foreach loop is done. wp_list_pluck() is also just a basic foreach loop if $index_key is not passed. Also, as with any foreach … Read more
