I wrote a tutorial for how to "Manage WordPress Posts Using Bulk Edit and Quick Edit" and decided it was best to convert my tutorial to plugin format and post online so I can better manage and keep up to date.
You can view the tutorial at: Manage WordPress Posts using Bulk Edit and Quick Edit - WPDreamer.com
With that said, you could easily take this code and paste it into your theme's functions.php file. There is, however, an included javascript file, so be sure to check the manage_wp_posts_using_bulk_quick_edit_enqueue_admin_scripts() function to confirm you're enqueueing the right javascript file.
Also, after a few requests for custom field examples other than textboxes, I updated the tutorial to include a select dropdown and a radio button.
Custom Fields:
- Release Date - input text
- Coming Soon' - input radio
- 'Film Rating' - select dropdown
If you find any issues with the tutorial, or code, please let me know. Thanks!
