• in reply to: Validation of a field based on the value of another field

Hello,
i’m trying to perform a validation on a field and in my functions.php I have the following code:

add_filter('acf/validate_value/name=initial_pos_val', 'my_validate_function', 10, 4);

function my_validate_function($valid, $value, $field, $input) {
    $valMin = $_POST['acf']['field_5abca98844f1c'];
    $valInicial = $_POST['acf']['field_5abcb00ba1ff6'];

    if ($valInicial < $valMin ) {
        $valid = "Error: The value is not allowed.";
    }
    return $valid;
}

All these fields are inside the same field group.
This is not performing the validation I want.
Can someone help please?
Thank you.
