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.
