The box which allows slug edition under the post title is actually tied to the slug metabox. It needs it to work. So, removing the metabox will break it. The only solution, I think, would be to use javascript or css to hide it. Something like this will work: function hide_slug_box() { global $post; global … Read more
Ok, all those hipercomplex functions can be reduced to one simple command: attachment_url_to_postid You only need to parse the image url to retrieve the attachment id: <?php $attachment_id = attachment_url_to_postid( $image_url ); echo $attachment_id; ?> That’s all you need.
You should never edit the core files of WordPress. Instead you should only ever edit Plugin files and or Theme files (Plugins or Themes folder) One of the easiest was to achieve this would be via jQuery; jQuery(‘<div/>’, { id: ‘your-note’, text: ‘Add up to 5 tags…etc’ }).appendTo(‘#tagsdiv-post_tag .inner’); Save the above into a alerts.js … Read more
There is at least 1 issue with using wp_editor in a meta box, as discussed in ticket #19173(Good read on the subject of wp_editor and meta boxes). TinyMCE gets all messed up if you move the meta box that contains it (specifically, if TinyMCE’s location in the DOM is changed). You can, however, use the … Read more
Straight from the WP Codex @ http://codex.wordpress.org/Function_Reference/add_meta_box, you call the save_post hook and specify the function that will be run to validate/save your data: /* Do something with the data entered */ add_action(‘save_post’, ‘myplugin_save_postdata’); Then you define that function, which will automatically be passed the post id. Additionally, you can access the $_POST array to … Read more
WordPress saves them in the databas in wp_usermeta as serilized array. For the dashboard all are registered in meta-box-order_dashboard if the meta-box(s) are in metaboxhidden_dashboard they will not be shown. The order will be as saved in database and if not in metaboxhidden_dashboard. Example the dashboard: KEY: meta-box-order_dashboard VALUE: Array ( [normal] => dashboard_right_now,dashboard_recent_comments,dashboard_incoming_links,dashboard_plugins [side] … Read more
That depends entirely on what you mean by “attach.” Each WordPress post can already have multiple media attachments – photos, documents, etc. You upload these using the built-in uploader and they’ll all be marked as “attached” to that specific post ID. You can refer to these later programatically elsewhere. For example, the following code will … Read more
It is hard to declare best practices here. The placement depends on the content of the metabox: an editor field would be too narrow usually in the side column; two small checkboxes on the other hand will look lost in the main column. To understand where which box will be placed, let’s use a small … Read more
On remove_meta_box is a note: Because you can’t remove a meta box until it’s been added, it’s important to make sure your call to remove_meta_box() happens in the right sequence. WordPress SEO adds meta boxes on add_meta_boxes action with default priority – 10, which run after admin_init, so that won’t remove them. Instead you need … Read more
I haven’t had time to test this but this looks like it should work for you. add_action(‘do_meta_boxes’, ‘remove_thumbnail_box’); function remove_thumbnail_box() { remove_meta_box( ‘postimagediv’,’post’,’side’ ); } Check this for more info. Edit: The main change here is that you need to attach the function to do_meta_boxes instead of admin_menu
