Prestashop 1.7 : dni is invalid when creating a supplier from B.O

Every time i'm trying to create a supplier from BackOffice, an error message is appeared: "dni is invalid" because invalid characters.

i have changed "isDniLite" in "validate.php" file but no luck.

i need that field to accept anything.

I am using Prestashop V1.7.7.0

Need help please. Thanks.

You have to go to the file yourshop\classes\Validate.php

In this file scroll down until you see function isDniLite($dni) and add following line:

public static function isDniLite($dni)
{
    return $dni; // Crezzur: Don't check, just accept variable input.
    // Disable the old return just to be sure:
    // return empty($dni) || (bool) preg_match('/^[0-9A-Za-z-.]{1,16}$/U', $dni);
}

The best practice is to write an override for this. But this is your free choice.

Update: Additional there is another place where a check for DNI is placed

You have to go to the file yourshop\js\validate.js

In this file scroll down until you see validate_isDniLite(s) and add following line:

function validate_isDniLite(s)
{
    return s;
    // var reg = /^[0-9a-z-.]{1,16}$/i;
    // return reg.test(s);
}
