How can i check European VAT-ID with rlValid.class.php

Hi Guys,

i have add a field in registration form for european VAT-ID.
Now i have a problem. I must check the VAT-ID.

Here for example a php script that check the european vat.

PHP Code:

---

Only registered members can view the code. 


---

My questions are follow.
1. For account fields there are some checking conditions (isURL, isDomain, isEmail). How can i add isVatId?
2. How can i add the above code to rlValid.class.php? The key for this field = c_ustid.

Best regards

OK Guys,

i have found the solution... It was very easy...
First i have add isVatId conditions list as follow in system.lib.php

PHP Code:

---

Only registered members can view the code. 


---

Furthermore, i have added the language phrase for isVatId (vatcheck).
So i can now create a function with name isVatId in rlValid.class.php and can assign them to the VAT-ID field.
At Last i just have to modify the above code and paste it into the isVatId function.
I have done as follow

PHP Code:

---

Only registered members can view the code.

Now we have add a new validcheck for account vat-id field.
NOTE! I check with this above code only German and Austrian VAT-ID.
If you want to validate vat-id by other european countries, the code must be extended and customized.

Hey Guys,

The problem is settled.
For all interested, the above steps you need to insert your own validation in flynax script.
