Users can drag and drop meta boxes and WordPress will save the order. So, in a sense, the order in which they were originally rendered does not matter. You know which one comes first because when you call add_meta_box it simply pushes your meta box’s args onto a global array called $wp_meta_boxes. Whichever call to … Read more
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

Additionally, you can access the $_POST array to … 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.
