hi
i need to validate a field in a form where a user enters their
lodgement number as part of a registration form. this lodgement number
can have letters, numbers, spaces and special characters. i do not
know exactly what those special characters are, so do i have to define
the type of special characters and validate accordingly.
presently my php code for validating the lodgement number is
$lodgementtf = $_POST["lodgementtf"];
if($lodgementtf == "" || !preg_match("/^[a-zA-Z0-9_ <]+$/",
$lodgementtf) )
{
echo "display error message":
}
i also have another way of validating
if($lodgementnumber == "" || !preg_match("/^[a-zA-Z0-9_
!-@£$%^&*()]+$/", $lodgementnumber) )
does this mean that the special characters can only be = a space AND
_!-@£$%^&*() and no other special characters.
please advice.
thanks.
