php - Wordpress / ACF field as an admin column -

i've created acf field named 'cislo_ponuky'. it's numeric.

what need display admin column in custom post type called nehnutelnosti owning slug of 'nehnutelnosti'.

add_action( 'manage_nehnutelnosti_custom_column' , 'custom_mycpt_column', 10, 2 );

function custom_mycpt_column( $column, $post_id ) { switch ( $column ) {

// display value of acf (advanced custom fields) field case 'acf_field' :   echo get_field( 'cislo_ponuky', $post_id );     break;

} }

this code's not working me unfortunately.

you can use "codepress-admin-columns" plugin admin column https://wordpress.org/plugins/codepress-admin-columns/
