In your functions.php : add_action(‘publish_post’, ‘check_user_publish’, 10, 2); function check_user_publish ($post_id, $post) { if($post_id == 1){ $query = array( ‘ID’ => $post_id, ‘post_status’ => ‘draft’, ); wp_update_post( $query, true ); } }
Query variable only can be accessed after wp_query has been called. In you call, the get_post_type() function is actually returning an empty value. It should be working, if you change the hook to something which fires after wp_query is called. So, You should use – add_action(‘wp’, ‘kiwi_remove_post_author_box’); OR add_action(‘template_redirect’, ‘kiwi_remove_post_author_box’); Also, hooks can removed with … Read more
Your proposal is OK – you can see this in action even in the WordPress itself. See admin-ajax.php where you can find this piece of code: // Register core Ajax calls. if ( ! empty( $_GET[‘action’] ) && in_array( $_GET[‘action’], $core_actions_get ) ) add_action( ‘wp_ajax_’ . $_GET[‘action’], ‘wp_ajax_’ . str_replace( ‘-‘, ‘_’, $_GET[‘action’] ), 1 … Read more
I think you’re on the right track with a filter. Have you tried login_body_class as the filter? function add_blog_id_to_login_page( $classes ) { $blog_id = get_current_blog_id(); $classes[] = “blog-{$blog_id}”; return $classes; } add_filter( ‘login_body_class’, ‘add_blog_id_to_login_page’ );
There is a filter called plugin_action_links that lets you do this. function wpse253902_disable_plugin_deactivation ($actions, $plugin_file, $plugin_data, $context) { if (array_key_exists (‘deactivate’, $actions)) unset( $actions[‘deactivate’] ); return $actions; } There is even a filter plugin_action_links_{plugin_name} that lets you control the links on individual plugins. If you dive into it, you will find out that you can … Read more
Just thinking on a Friday night (so untested), but: You are outputing the result directly to the page. Of course it is going to display straight after the body tag. What you need to do is store that HTML snippet, and append/insert into the content using the_content filter as s_ha_dum suggested. This is untested, and … Read more
You can’t put AJAX into the callback for a shortcode. It doesn’t make any sense to. If you’re making an AJAX request then you’re making it on the front-end and the shortcode has already rendered. So anything you do with the response to the AJAX request needs to occur on the front-end. So what you … Read more
You can’t protect against everything a user will do. What if they hard-code an email address in the footer/header/sidebar of their theme? The only way to capture and escape that is with output buffering … and that can become a performance nightmare. My recommendation would be to do two things: Hook in to all of … Read more
I think it is always better to use the API, the functions of WP in this context. The function wp_load_alloptions() is under maintain and a custom select must always tested and maintain. Also the function use the Cache, if the installation support this. A good point for performance. The function supports also the Multisite installation, … Read more
The original function ends with this line: return apply_filters( ‘presscore_get_page_title’, $title ); That’s your cue. You can build a filter that completely overrules the $title generated by that function. Like this: add_filter (‘presscore_get_page_title’,’wpse263380_presscore_get_page_title’,10,1); function wpse263380_presscore_get_page_title ( $title ) { $title=”My awesome title”; return $title; }
