选择选项未将值传递给Codeigniter中的控制器功能

Question

I am trying to save all the values as an array using select2 ajax selectbox (selectbox2.github.io) but my controller class is not getting any value from the view class in the codeigniter, I replaced the select2 box with normal textbox, then it works correctly.


1. why select2 is not passing values to my controller class or my controller class is not picking up the values from the view class.

2. I have created append class function to add new blank row of select2 elements, when my page load the append functions works correctly but when I am trying to call the same function on click event nothing appears on screen.

code of view class

I use something like this, using Jason:

My JS:

function deletefile(delstring_val,typestring_val,filedirectory_val)
{

    if(r == true)
    {
        $.ajax({
          url: 'delete.php',
          data: {delstring: delstring_val, typestring: typestring_val},
          type: 'POST',
          success: function (response) {
              alert(response);
              document.location.href = newURL;            
          },
          error: function () {
             alert('ERROR deleting the item !!'); 

          }
        });

    }
    else
    {
        alert('Item deleting was cancel !!');
    }
}

My html:

<td> <a href='#' onclick = 'deletefile("<?php echo $basedir."/".$dir."/".$files[$row1];?>","<?php echo $tipo[$row1];?>","<?php echo $dir;?>");'>Delete</a> </td>

In my Delete.php:

$testetype=$_POST['typestring'];

It works, if you need help, comment that I will try to help.
