jquery post & ci form validation

[eluser]Nick Husher[/eluser]
I don't think such a thing is possible without somehow decoding the JSON and inserting it into the $_POST associative array. The best way to do that might be by extending the Validation library with a MY_Validation class.

The code might look something like this:

Code:

//php
foreach($_POST as $key=>$property) {

    // json_decode returns null or a string if the json given to it is
    // invalid. see:
    // http://us2.php.net/manual/en/function.json-decode.php#86181
    //
    // the second argument forces json_decode to use an associative array
    // instead of a stdClass Object
    $json_object = json_decode($_POST[$property], true);
    $is_json = ($json_object != null && !is_string($json_object));

    if($is_json) {
        array_merge($_POST, $json_object);
    }
}
