Hello,
I have 2 time pickers fields, where the fields are intendent for meetings.
There should be a check control just to check that the first time picker cannot be lower then the second time picker when saving a post.

Any tips and tricks?

Hi @zilveer

You should be able to use the acf/validate_value hook. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/acf-validate_value/. It should be something like this:

add_filter('acf/validate_value/name=time_start', 'my_acf_validate_time', 10, 4);

function my_acf_validate_time( $valid, $first_time, $field, $input ){
    
    // bail early if value is already invalid
    if( !$valid ) {
        
        return $valid;
        
    }
    
    // remove the ":" char from the time and set the value as int
    $first_time = (int) str_replace(':', '', $first_time);
    $second_time = (int) str_replace(':', '', $_POST['acf']['field_588425efcdf00']);
    
    // compare the time
    if( $first_time < $second_time ){
        $valid = 'Start time should be after end date ';
    }
    
    // return
    return $valid;
}

I hope this helps 🙂
