Fix for undesired result of the valid_ip form validation rule forcing it to be required field - El Forum - 05-09-2010

The valid_ip form validation rule runs through the input->valid_ip checker. This in essence makes the field a required field and will fail if empty. Might not be a big deal in some applications, but I have come across an occasion or two where I needed to only check for a valid ip if the field was required by the required rule and ignore it if not required.
Original Rule:
Code:
function valid_ip($ip)
{
return $this->CI->input->valid_ip($ip);
}The fix is simple, just override it in your MY_Form_validation class.
Code:
function valid_ip($ip)
{
if( !empty($ip)) return $this->CI->input->valid_ip($ip);
return TRUE;
}If in your validation rules you just specify "valid_ip" it will only check the field for a valid ip if its not empty, making it not required like I think it should be.
