jQuery form validation using CI back-end rules - El Forum - 03-05-2011

I created solution that does front-end validation using back-end validation rules. No more writing separate validation routines and you get the same native CI validation error messages on front-end.

I just wanted to come back and /bump this thread - and say thanks again to Steelaz - this is an awesome addon - which has saved me so much time, and greatly improved the logic and cleanness of my website code.
Thanks!!

I do the same thing except I created a new method in MY_Form_Validation to return the validation error ARRAY ($_error_array), so I can highlight the individual error fields when it gets returned to the ajax callback as a json object. (as opposed to just using validation_errors() which returns a single string with all errors)

question: has anyone here been able to get this to work when CSRF is turned on? Mine stops working - and I'm not 100% sure how to fix it....

I needed a quick fix for this - so I decided that a solution would be to "ignore" the CSRF check for the jquery validation calls.
There is no (obvious) security risk I can see here, because the validation rules are public knowledge anyway (since we send them as text to the browser).
To achieve this, I extended the Security class, and did a check for the "welcome/remote" URI. For me, this is my generic path that all my jquery validation goes to. Just change "welcome/remote" to wherever your remote() function is.
Code:
<?php
/**
* A fix to ignore CSRF tokens for the jquery_validation
*
*/
class MY_Security extends CI_Security
{
public function __construct()
{
parent::__construct();
}
public function csrf_verify()
{
// Firstly - manually get our controller/method
// We cant use the CI instance yet
$uri = $_SERVER['REQUEST_URI'];
if (strpos($uri, $_SERVER['SCRIPT_NAME']) === 0)
{
$uri = substr($uri, strlen($_SERVER['SCRIPT_NAME']));
}
elseif (strpos($uri, dirname($_SERVER['SCRIPT_NAME'])) === 0)
{
$uri = substr($uri, strlen(dirname($_SERVER['SCRIPT_NAME'])));
}
// Check if this is a jquery remote check
$pos = strrpos ($uri, "welcome/remote");
if ($pos === false)
{
// No? Then complete the csrf check as normal
return parent::csrf_verify();
}
else
{
// Yes? Then just ignore it as if nothing happened
return $this;
}
}
}If anyone can see any flaws/security issues with this - I'd be keen to hear it...

Just pass the CSRF token. Much better than disabling security.
