Each nav menu item is stored a post type named nav_menu_item. The horizontal position is stored in the column menu_order The vertical position (hierarchy) is stored as post meta field named _menu_item_menu_item_parent holding the parent nav_menu_item ID. To create nested lists WordPress looks for _menu_item_menu_item_parent on each item, and if there is an item with … Read more
Yes, it does. That function is a wrapper for get_metadata(). Inside of that you can find: $meta_cache = wp_cache_get($object_id, $meta_type . ‘_meta’); if ( !$meta_cache ) { $meta_cache = update_meta_cache( $meta_type, array( $object_id ) ); $meta_cache = $meta_cache[$object_id]; }
You generally use add_filter before displaying information. For your case you can use add_action(‘publish_post’, ‘your_function’) and then you intercept $_POST values. The content of the WYSIWYG editor is available through $_POST[‘content’]. The hook is of type publish_{post_type} btw. You should change accordingly. Example: function wpse_89292_save_my_post() { print_r( $_POST[‘content’] ); # will display contents of the … Read more
This is a serialized value, so you should run it through maybe_unserialize() or just unserialize() before you edit it. When you work in plugins or themes, always use the API: update_option() and get_option() for example. These functions will un/serialize the values for you, so you don’t have to worry about the database. See also: Settings … Read more
First of all, the prefix is only a configuration option and not a security feature. The reason is that once an attacker has access to your database, he can find out any exisiting table prefix within seconds. There’s no way this obscurity protects you from any attack. For the prefix itself, WordPress asks you to … Read more
I don’t exactly know about the word embed, but by default WordPress reserves & uses these sort of words for internal use. I tried to create a page slug named embed but it wouldn’t work for me either on my localhost or on my live server. Maybe this is reserved for WordPress oEmbed functionality.
Yes, you can use wp_update_user(): wp_update_user( array( ‘ID’ => 123, ‘user_nicename’ => ‘value’ ) ); Just replace 123 with the proper user ID, and value with the preferred user_nicename value. The function also enables you to change the value of other fields in the WordPress users table (wp_users).
You’re probably running into the joys of MySQL’s MyISAM engine… From within MySQL (or PhpMyAdmin), use REPAIR TABLE xyz statements again, repeatedly, on each of your tables (or rather, your terms related tables, since these are the ones that sound corrupt) to see if this solves anything. If those fail, there are a few documented … Read more
this comes down to a simple one line and there is no need to get all of the children using: $featured image_id = get_post_meta( $post_id, ‘_thumbnail_id’, true );
Some notes before: This is only how I’d approach it – I’m not going to step more into detail, because basically it’s a list of plugins you’ll have to code. Build a Back-End page Use the function add_menu_page to add a page. Then build your management tables extending the WP_List_Table class: class WPSE_48824_List_Table extends WP_List_Table … Read more
