Adding Post Type Columns

The Post Type Columns field in the Pollux settings contains the column labels that are shown in the Post Type admin page table.

Built-in columns include:

• author
• categories
• comments
• date
• media
• slug
• thumbnail
• title

The slug column displays the slug of the post_type.

The media column displays a count of images uploaded in a meta-box with an ID of "media".

The thumbnail column display a thumbnail of the featured image if set.

All other built-in columns should be self-explanatory.

To add your own custom column

1. First you must add the column to the Post Type columns key in the "Post Types" field:

columns:
  - title
  - my_awesome_column
  - date

2. Next you must add the custom column label in the "Post Type Columns" field:

my_awesome_column: Awesome!

3. Finally, you must create a special file called pollux-hooks.php and place it either in your root web directory, or in the wp-content directory. Once you have created the file, add a custom filter in it to populate the custom column with a value:

add_filter( 'pollux/post_type/column/my_awesome_column', function( $value, $post_id ) {
    return PostMeta::get( 'awesome_value', [
        'fallback' => $value,
    ]);
});
