Okay, I found an answer myself. To help people who will read this in future, this is what I did: 1) This explains how to add a column: http://www.deluxeblogtips.com/add-custom-column/ 2) This explains how to add a sortable column: https://wordpress.org/support/topic/admin-column-sorting/
I had a similar problem and managed to solve it. In my case I have a custom taxonomy, issue, which contains a required date picker custom field using the ACF PRO plugin—the field name is issue_date. I wanted to add the date column to my issue edit screen at wp-admin/edit-tags.php?taxonomy=issue and I wanted to allow … Read more
With the above shown function split_content() it’s not possible to build a three column layout. It basically splits the content with the <!– more –>-Tag into half and then builds two columns (in a pretty complicated way). Maybe it works with adding multiple <!–more–>-Tags to your post content in the HTML-Editor.
Here is an interesting approach: THE PLAN AND LOGIC: Custom fields are a build in functionality that will fit our needs perfectly. We can set a new custom field and then use that field to enter and store our custom data. We can then use a widget to display this custom content in the sidebar … Read more
First of all, never use query_posts Note: This function isn’t meant to be used by plugins or themes. As explained later, there are better, more performant options to alter the main query. query_posts() is overly simplistic and problematic way to modify main query of a page by replacing it with new instance of the query. … Read more
Short answer Simple as things sometimes are: No this is not possible. The whole part is hard coded. Long answer (not recommended to do so) You could maybe jump into the esc_html and attribute_escape filters and just return empty there *), but as those are pretty generic names and would possibly also interfere with other … Read more
That’s the only thing there is to do: array manipulation. The filter manage_edit-CPT_columns is fired in class-wp-list-table.php: add_filter( “manage_{$this->screen->id}_columns”, array( &$this, ‘get_columns’ ), 0 ); Which in turn dispatches the function get_columns() in the sub-class class-wp-posts-list-table.php. And, inside it, one filter for taxonomies, and others for post/page/cpt columns. And all of them dealing with array … Read more
If you want to target all custom post types as well as the built in post types (posts and pages) then you need to use the manage_posts_custom_column hook instead of the manage_{post_type}_posts_custom_column hook which is used to target specific post type columns, subtle difference in naming convention but big difference in how they operate. Example: … Read more
There are no direct filters using which we can change the content of Name column. So to get what you want, we should remove ‘Name’ column too and create our own Name column. Therefore, modify_user_columns function will be like this function modify_user_columns($column) { $column = array( “cb” => “<input type=\”checkbox\” />”, “wdm_name” => __(‘Name’), “email” … Read more
The hook for these columns is manage_media_columns. So just filter the columns here: add_filter( ‘manage_media_columns’, ‘wpse_77687_remove_media_columns’ ); function wpse_77687_remove_media_columns( $columns ) { unset( $columns[‘author’] ); unset( $columns[‘comments’] ); return $columns; }
