wp_ajax_(action) hook doesn't work in media gallery

[hoandang]

Step to reproduce:

1. Open an image in Grid view mode
2. Change image title
3. Add this hook in functions.php

   <?php
   add_action('wp_ajax_save-attachment', function($array, $int) {
       var_dump('save-attachment');
   }, 10, 2);
   

Expected: A var_dump result in http network.
Actual: http always responses {"success":true}

Hi @hoandang

Not able to see anything from the url you provided. Is there something you want to point out by that url

Sorry, I can't see the button to edit my post. Please see the fixed image ​http://i.imgur.com/pGF8Rku.png

Just to elaborate the bug, the ajax request comes from media gallery not from my custom ajax request. The hook works fine with "wp_ajax_save-attachment-compat" but "wp_ajax_save-attachment"

@hoandang where and how are you getting the var_dump output?

[hoandang]

Just double-checked the doc and it states that the "wp_ajax_(action)" hook works only with custom ajax requests, so that explains the builtin wordpress ajax requests such as "save-attachment" don't work.

The issue seems to be a missing feature in wordpress, it is not really a bug.
