Adding uploaded images to editor from metabox instead of default popup uploader

Faster Image Insert? Moves built-in Media Manager down in a meta-box, right next to main editing panel, so you have full control of the manager: opens it, makes it collapse or hidden from the interface completely. Best of all, is now you can insert image(s) much faster, and precisely where you want them to be.

Can I limit this meta box to a particular page?

Inside your add_meta_boxex hook callback function, you will have an add_meta_box() call. Wrap that call in a conditional, using data from the $post global (I’m fairly certain it is available in edit.php). For example, you could use either the Page ID or slug. Page ID: global $post; if ( ‘123’ == $post->ID ) { // … Read more

Populating meta box with select-list of existing posts, and assigning it to custom post types

I believe this is what you were looking for. I moved back to using a class because what you were using would very easily conflict with someone else’s code who decided to use the function names select_box_add_meta_box(), select_box_content() and/or select_box_save_postdata(), which is reasonably likely. The class name WPSE_85107 is only likely to conflict with somebody … Read more

This isn’t complete copy/paste code, but hopefully it’s understandable enough to get you started. First step is to register your post type and add a rewrite rule to handle years/months.

Make parent categories not selectable This is the result, top-level categories are converted to radio buttons, so only one … Read more

Order custom posts by a date metabox

When you’re saving the data on your custom post type you need to set it so that the meta box value is actually stored as a UNIX timestamp, eg: if(!isset($_POST[“event_informations_date”])) { return $post; } else { $event_as_timestamp = strtotime ( $_POST[“event_informations_date”]; update_post_meta($post->ID, “event_informations_date”, $event_as_timestamp ); } This way you will have an orderable value for … Read more

Custom field being erased after autosave

I use the following code to prevent updates of my custom fields during auto-saves, ajax requests (quick edit) and bulk edits. add_action(‘save_post’, ‘save_my_post’); function save_my_post($post_id) { // Stop WP from clearing custom fields on autosave, // and also during ajax requests (e.g. quick edit) and bulk edits. if ((defined(‘DOING_AUTOSAVE’) && DOING_AUTOSAVE) || (defined(‘DOING_AJAX’) && DOING_AJAX) … Read more

Custom field values get deleted

Check your variables before you work with them. Your save function gets a parameter $post_id. Use it. From my meta box class for a check box: /** * Saves the content to the post meta. * * @return void */ public function save( $post_id ) { $this->is_allowed_save( $post_id ) and update_post_meta( $post_id, $this->vars[‘key’], empty ( … Read more
