Question

Okay so basically i’m trying to submit a form with some javascript arrays.

I expected this to take the form add the data to hidden fields and then post it automatically.

However I’m getting a strange error.

1. The fields added dynamically aren’t coming as hidden and are showing on screen.

2. The code is working extremely slowly(running this locally so I can’t imagine why)

3. It doesn’t link to the PHP page but instead says: The connection to 10.0.0.2 was interrupted.(NOTE: The PHP page is valid and can be visited otherwise)

In this code correct and answers are javascript arrays

$("#questionForm").submit(function(e){
                e.preventDefault();
               var cform = $('<form></form>');
               cform.attr("method", "post");
               cform.attr("action"," <?php echo base_url()?>index.php/TestMaker/endTest");
               var cfield = $('<input></input>');
               cfield.attr("type", "hidden");
               cfield.attr("name", "correct");
               cfield.attr("value", correct);
               cform.append(cfield);
               cfield=$('<input></input>');
               cfield.attr("type","hidden");
               cfield.attr("name", "answers");
               cfield.attr("value", answers);
               cform.append(cfield);
               $(document.body).append(cform);
               cform.submit();
});

EDIT

Okay the hidden part is fixed. Error in the second field. Didn’t set it hidden.
Server Side Code:
class TestMaker extends CI_Controller{

 function __construct() {
    parent::__construct();
 }

 function endTest(){
    $correct_arr=$_POST('correct');
    echo "hi";
    //$question_ids=$_POST('question_ids');
    //$question_types=$_POST('question_type');
 }
}

Answer 1

You’re accessing the $_POST array wrongly, the correct way of accessing an array in PHP is using square brackets [], like this:

$correct_arr = $_POST['correct'];

Also, if you’re using CI, there’s a input class which wraps the $_POST array and is quite helpful, which can be used this way:

$correct_arr = $this->input->post('correct');
