    Hi Ally,

    If I understood correctly with this code the input will check if the IBAN numbers are valid?
    Despite having 22 characters the validator will recognize the numbers of account? Like on example with credit card.. I attach pic if you know what i mean.

    Best regards,
    Marko

    Hi Ally,

    One more thing. I tried to implement the code

    add_filter(‘quform_element_valid_5_37’, function ($valid, $value, Quform_Element_Field $element) { if (!preg_match(‘/^[A-Z]{2}[0-9]{2}[A-Z0-9]{1,30}$/’, $check)) {
    return false;
    }

    $country = substr($check, 0, 2);
    $checkInt = intval(substr($check, 2, 2));
    $account = substr($check, 4);
    $search = range(‘A’, ‘Z’);
    $replace = [];
    foreach (range(10, 35) as $tmp) {
    $replace[] = strval($tmp);
    }
    $numStr = str_replace($search, $replace, $account . $country . ’00’);
    $checksum = intval(substr($numStr, 0, 1));
    $numStrLength = strlen($numStr);
    for ($pos = 1; $pos < $numStrLength; $pos++) {
    $checksum *= 10;
    $checksum += intval(substr($numStr, $pos, 1));
    $checksum %= 97;
    }

    return ((98 – $checksum) === $checkInt); { $element->addError(‘The value is not Foo’); $valid = false;
    }

    return $valid;
    }, 10, 3);

    Is this right?
    My element unique ID is 5_37. This is my form link im trying to implement the IBAN validator.

    Hi Ally,

    It worked excellent! Thank you for your time.
    One more thing. How to add to other forms that i have the same function?
    There unique IDs are 4_37, 3_37, 6_37, 1_37
    Same forms, different locations.

    Best regards.
    Keep up with good work!
