Validation for URL data submitted as POST or GET from external URL - El Forum - 09-02-2010
[eluser]Brian Loomis[/eluser]
I'm interested in finding a good method to validate parameterized URI being sent to our application as part of a testing process. I've worked with the form validation but not sure if this is what I want. I've also searched the forums and seem to find no information on validating parameters besides the form validation class. There is a form_validation library and a validation library. However the documentation only references the form_validation library, I'm assuming because most validation is form based.
Does anyone have any suggestions on resources for doing standard validation techniques on data that comes from a URI request and not a form?
Thanks in Advance.

I've also checked the Packt codeigniter book and the Wrox book with no information about using the libraries in this manner.

So this is what my code looks like, trying to capture incoming requests and archive them and need to validate if they are valid or not.
class Incoming extends Controller {
function index()
{
parse_str($_SERVER['QUERY_STRING'],$_GET);
// checks for incoming requests:
// Post: http://www.xyz.com/incoming/?z=m&c=3&l=19&y=1&s=344&f=122
$this->load->helper(array('form', 'url'));
$this->load->library('validation');
$rules['c'] = "required";
$rules['l'] = "required";
$rules['y'] = "required";
$rules['s'] = "required";
$rules['f'] = "required";
$this->validation->set_rules($rules);
$data['info']=$this->validation->run();
if ($this->validation->run() == FALSE)
{
$this->load->view('Incoming_fail',$data);
}
else
{
$data['c']=$this->input->get_post('c', TRUE);
$data['l']=$this->input->get_post('l', TRUE);
$data['y']=$this->input->get_post('y', TRUE);
$data['s']=$this->input->get_post('s', TRUE);
$data['f']=$this->input->get_post('f', TRUE);
$this->load->view('Incoming_index',$data);
}
}
}
So this always triggers that it is invalid, even when all my parameters are present.
What changes can I make to validate get requests instead of form posts?

I still haven't found a good solution:
There is this one:
http://ellislab.com/codeigniter/user-guide/libraries/form_validation.html
and this:
http://ellislab.com/codeigniter/user-guide/libraries/validation.html
But nowhere does validating GET requests covered in the documentation or either of the two CI books I have from PACKT or REILLY. I'd like to validate parameters coming in in query strings.
I think this is because CI does not use query strings as a default and you have to manually override it's default behavior to do this.
Also I've looked into http://ellislab.com/codeigniter/user-guide/libraries/unit_testing.html but I'm not interested in doing TDD at this point just having some handy shorthand for validating the querystrings we have coming into the application.

This seems like it will fit the bill.
Thanks for all your help everyone...

That library actually doesn't have a helper it needs, the current version is missing it.
Instead I found another solution using jQuery to convert the GET requests the HTTP links were generating to POSTS so that the regular form_validation libraries work.

Use Postlink.

This would still be a useful thing to be able to do though with the CodeIgniter validation library, for an application that needs to support JSONP requests ie. input validation of get parameters from a querystring.
