Hello Long,
sorry I am not a programmer. I don't know how to use this correctly.
My site is still crashing after using this
add_action( 'admin_init', 'prefix_add_custom_columns', 20 );
function prefix_add_custom_columns() {
if ( ! function_exists( 'rwmb_meta' ) ) {
function rwmb_meta( $key, $args = [], $object_id = null ) {
return null;
}
}
class Prefix_Custom_Admin_Columns extends \MBAC\Post {
public function columns( $columns ) {
$columns = parent::columns( $columns );
$position = 'before';
$target = 'title';
$this->add( $columns, 'featured_image', 'Image', $position, $target );
// Add more if you want
return $columns;
}
public function show( $column, $post_id ) {
switch ( $column ) {
case 'featured_image':
the_post_thumbnail( [60, 60] );
break;
// More columns
}
}
}
new Prefix_Custom_Admin_Columns( 'post', array() );
new Prefix_Custom_Admin_Columns( 'page', array() );
new Prefix_Custom_Admin_Columns( 'review', array() );
}
Can you please correct it for me?
Jochen
