Need some help with an action hook

[Milliment]

Hi guys i wonder if anyone can help me with this,

 

In italy we need to take a Codice Fiscale (National insurance number or Social Security) for any orders.

 

Now before i desided to use WHMCS i was developing my own system but gave up as i dident have the time to do it.

 

Anyway i wrote a function that would check if the Codice Fiscale was the correct make.

 

Now here is my origional script

 

 function valid_cf($str)

{

	return ( ! preg_match ( "/^[a-zA-Z]{6}[0-9]{2}[a-zA-Z][0-9]{2}[a-zA-Z][0-9]{3}[a-zA-Z]$/", $str ) ) ? FALSE : TRUE;

}

 

Can anyone help convert it into a working action hook please.

 

Thanks

Anthony

I don't think an actionhook is necessary for what you're trying to accomplish. In fact, it may be overkill. My suggestion would be to create a custom client field and use your regex string for validation, which can be pasted right into the validation box when creating the field.

Ahhhhh ok, so the validation field can accept php, i did not no that.

It doesn't accept PHP, but accepts a regular expression check which you also use in your PHP-code.

Exactly, so if your expression doesn't return a match the field doesn't pass validation. Pretty slick actually.

It's just the expression from the PHP-code from the first post:

/^[a-zA-Z]{6}[0-9]{2}[a-zA-Z][0-9]{2}[a-zA-Z][0-9]{3}[a-zA-Z]$/
