ERROR - Identification Number in PS 1.7

[Web Curator]

Hi Guys

 

I have a problem with the IDENTIFICATION NUMBER during the checkout.

 

Even if you complete the field correctly, I have this bad feedback:

 

INVALID FORMAT

 

Do you know how to fix this validation or disable it? somebody else with the same problem?

 

 

Best

At the moment the validation of the Identification Number seems is made by the function isSiret in the file Validate.php

but is made for only the french public... maybe is this one the error?

 

For a w.w. e-commerce we need a check that include only String and Numbers?

    public static function isSiret($siret)
    {
        if (Tools::strlen($siret) != 14) {
            return false;
        }
        $sum = 0;
        for ($i = 0; $i != 14; $i++) {
            $tmp = ((($i + 1) % 2) + 1) * intval($siret[$i]);
            if ($tmp >= 10) {
                $tmp -= 9;
            }
            $sum += $tmp;
        }
        return ($sum % 10 === 0);
    }
