Code Snippets

These code snippets can be placed in your theme's functions.php file.

Update the modified date after using inline edit for custom fields

By default, the Post Modified date will not be updated when you use inline edit for custom field related columns. This is because of the default behavior of WordPress that does not update a post when using the  update_post_meta. In Admin Columns we chose to leave this as it, but with the following snippet, you can update the post to update the post modified date.
