Validation VAT number

[parat10]

Hello,

 

I need to validate VAT number in registration form. I made new function in Class/validate and in class/adress change in $fieldsValidate vat_number => isGenericName to =>myFunction.

 

And nothing happend.

 

What should I do? Anyone any help or advice?

 

Thanks

Activate the VAT module on your back-office -> modules. Set to automatic validation: Enable checking of the VAT number with the WebService

It is not working in my country and it's super slow.

Is there any solution only with regular expression (I don't need to validate if it's real, only if it's in right form).

 

Thanks

can you show how your functions looks like? (you said that you created own validate function)

In validate.php in ValidateCore:

 

public static function isDicCZ($vat_number)

{

return preg_match('^[a-zA-Z]{2}[0-9]{8,10}$', $vat_number);

}

 

In adress.php in $fieldsValidate:

 'vat_number' => 'isPostCode',

in fact each country has a little different method to create vat numbers. it mean that each country must use different validation method.

in addition, if structure of vat is valid, it doesn't mean that this vat number exists! this is why it's necessary to validate it with your tax government services, for example VIES.
