Thank you for the reply.
If it’s not too much to ask, could you go into a bit more detail, perhaps with an example relevant to my situation? I don’t think I’m quite grasping how to use this correctly.
function my_acf_prepare_field( $field ) {
$field['value'] = 'Test';
$field['readonly'] = true;
return $field;
}
add_filter('acf/prepare_field/type=tab', 'my_acf_prepare_field');
I expected the above code to render all my Tab labels with the value of “Test”, but none of them changed.
