New action hook for edit.php for plugin authors to add new filter field...

[nerrad]

Why? If plugin authors want to be able to add a new field for filtering the posts on the "Manage->Posts" menu they can use this action hook to insert the form field before the submit button.

Currently (2.5 beta 1) it is possible to add a field via the 'restrict_manage_posts' action hook (see attached screenshot for example) but that is a cludgy solution at best and isn't good for user-friendly ui.

(This would be a complement to ticket: #5899)

suggested implementation

Hmm that looks like restrict_manage_posts may have ended up in the wrong place after the latest changes.

I'll look into this.

I don't think restrict_manage_posts is in the wrong place. My understanding is that it's purpose is for adding hook for filtering by type should a plugin author create a new post type. Therefore you'd want restrict_manage_posts to be where it is for adding in the same line as the other post-type filter options.

However, my suggested new action hook would be for plugin authors to add in a new form-field for filtering by a new post-taxonomy in the indicated location. It'd be nice to have the option of the two possible locations for insertion rather than just one (due to the new ui layout)

restrict_manage_post is in the wrong place - trust me I invented it ;-) [4321]

Unfortunately because of the design of the new admin ui where the whole list is inside the form we can't let plugins add there own form.

I think we need to move restrict_manage_post inside the form back where it should be rather than add another hook - and make sure to notify plugin authors that it has changed slightly.

restrict_manage_post plugin which works for 2.3

restrict_manage_post plugin which works for 2.5

I have attached two sample plugins.

The first was my original test plugin for this hook when it was introduced and works fine in 2.3

The second is a version which will work for 2.5 once I check in a fix for this hook in the next few minutes.

Please re-open if there are still issues.

(In [7274]) Move the restrict_manage_post hook back to a useful place. Fixes #6196.

Works for me :) Thanks!
