ctype_alnum($this->input->get('code', true)) not work? - El Forum - 06-06-2011

Hi. I'm doing a check to see if the get input is alpha numeric but I get this error. Anyone know how I can resolve this or there's a way to validate?
Fatal error: Can't use function return value in write context
Thanks.

Use CI Form Validation Class and set the matching rule like:
Code:
$this->form_validation->set_rules('input_field_name', 'Your Input Field Title', 'alpha_numeric');Don't forget we have the very helpfull User Guide!

Sorry I didn't put enough info. That is actually from the query string. And it seems the form validation only for form inputs. I tried this with the input->get but it saying undefined index.
Is there a validation class for input->get? If not how can I do alpha_numeric check for input->get data?
Thank you.

What happens if you use
Code:
$code = $this->input->get(‘code’, true);
ctype_alnum($code);Code:
ctype_alnum($this->input->get(‘code’, true));ctype_alnum($this->input->get('code', true)) not work? - El Forum - 06-07-2011

Did you enable query strings? I guess all get data is filtered otherwise.
By default the GET array is destroyed before a controller is called.

Hi. It seems it works using this. preg_match("/^[A-Za-z0-9]+$/", $code)
I guess this is more a problem in php side instead. Thank you for your help.
