    Hi guys,
    I have followed along with some custom code I found in this forum trying to display the featured_image in the admin columns before the Title. But it breaks my site.

    I don't have a theme, so I don't use functions.php. Instead I use Code Snippets to add custom PHP.

    Is there some code somewhere that provides a working example of how to display the featured image in the Admin Columns?

    Thanks for your time.

    John Anderson.

    Hi John,

    Please try this snippet:

    add_action( 'admin_init', function() {
        class My_Featured_Image_Columns extends MB_Admin_Columns_Post {
            public function columns( $columns ) {
                $columns  = parent::columns( $columns );
                $position = 'before';
                $target   = 'title';
                $this->add( $columns, 'featured_image', 'Featured Image', $position, $target );
                // Add more if you want
                return $columns;
            public function show( $column, $post_id ) {
                switch ( $column ) {
                    case 'featured_image':
                        the_post_thumbnail( [40, 40] );
                    // More columns
        new My_Featured_Image_Columns( 'post', array() );
    } );

    Oh! I love you!!! lol.

    And you updated the documentation for Admin Columns with this example! Now I just change the 'post' slug to what ever slug my CPT is and it will display the featured image in the admin columns.

    Thank you!

    Just one last question.

    new My_Featured_Image_Columns( 'post', array() );
    when I instantiate the class, how would I do so for more than 1 CPT? I tried this but it didn't work.

    new My_Featured_Image_Columns( array('team-member','challenge'), array() );   

    So I am guessing that 2 instantiations are necessary.

    new My_Featured_Image_Columns( 'team-member', array() );
    new My_Featured_Image_Columns( 'challenge', array() );

    Thank you,

    Hi John,

    You're right about 2 instantiations. Because the class is designed for single post type, we can't pass an array to its constructor. Initializing it twice for different post types does the job.
