Right before image subsizes are created, there’s a filter called intermediate_image_sizes_advanced that lets you modify the list of sizes. Here’s code that you could expand on — right now it just removes the thumbnail as a proof of concept: function remove_image_sizes_before_generation( $new_sizes, $image_meta, $attachment_id ) { $width = $image_meta[0]; $height = $image_meta[1]; // … Calculate aspect … Read more
That’s because you’re not using add_action correctly, what you’ve written is functionally the same as this: function xyz_footer_print() { echo ‘footer script here’; } $value = xyz_footer_print(); add_action( ‘wp_footer’, $value ); xyz_footer_print() immediately runs the function and returns nothing. As a result your add_action call says that on the wp_footer even, do nothing. So you … Read more
Am I using this hook incorrectly No, you’re not. is there another way to get the ID? Yes, try this: function add_menu_field( $item_id, $item, $depth, $args, $id ) { $id2 = 0; if ( ! $id && isset( $_GET[‘menu’] ) && $_GET[‘menu’] ) { $id2 = absint( $_GET[‘menu’] ); } elseif ( ! $id && … Read more

It was achieved using two hooks. retrieve_password_notification_email retrieve_password_message function ashad_retrieve_password_notification_email($defaults) { $defaults[‘headers’] = array(‘Content-Type: text/html; charset=UTF-8’); return $defaults; } add_filter(‘retrieve_password_notification_email’, ‘ashad_retrieve_password_notification_email’, 10, 3); function ashad_reset_password_message($message, $key, $user_login, $user_data ) { $user_fullname = $user_data->user_firstname . ‘ ‘ . $user_data->user_last_name; $blog_name = get_bloginfo(‘name’); $reset_url = network_site_url(“wp-login.php?action=rp&key=$key&login=” . rawurlencode($user_login), ‘login’); ob_start(); include(get_stylesheet_directory() . ‘/templates/mail/password-change.php’); $message = ob_get_clean(); return … Read more
Long-running software may be able to register functionality once and leverage those registrations for every connection across the lifetime of the process, but in the case of WordPress (and most of the PHP web software landscape as a whole) the long-running connection management is offloaded to the web server software. WordPress executes from the top … Read more
The get_calendar filter hook will allow you to modify the HTML generated by get_calendar() prior to displaying it. Duplicating the get_calendar() function in your functions.php file will throw a fatal error, since you’ll be redeclaring an existing function. (You can get around this by calling it something else, like function wpse410569_get_calendar(…), but I’d recommend using … Read more
As mentioned in the ticket #16470 this confirmation feature: prevents accidental or erroneous email address changes from potentially locking users out of their account. so it’s good to keep that in mind before removing this feature. Here’s a little proof of concept for (single site) test installs. We still want to run send_confirmation_on_profile_email() because it … Read more
Must-use (mu) plugins are loaded during the version update process, unlike ordinary plugins. Explanation here. So it’s possible to hook dbdelta_queries and the related filters from within a mu plugin. (Thanks to Sergey Biryukov for the answer.) But, some plugins use the same dbDelta() function as core update, so it’s possible to get queries for … Read more
