pass array from query to controller, codeigniter

Question

I have CodeIgniter question. How can I pass an array from view to controller? I am not able to send data to controller from view by calling public function sms() on a button click.

Here is my code that doesn't work:

<script>
function send_sms() {
    var chkBoxArray = new Array();
        $(document).ready(function (e) {

        $('#table input[type="checkbox"]:checked').each(function () {
            var getRow = $(this).parents('tr');
            chkBoxArray.push(getRow.find('td:eq(9)').html());
        });

        alert(chkBoxArray);
        reload_table();
    });

    $.ajax({
        url: "<?php echo site_url('person/sms')?>",
        type: "POST",
        data: { 'arr': chkBoxArray },
        dataType: "JSON",
        success: function (data) {
            // if success reload ajax table
            // alert(chkBoxArray);
            // reload_table();
        },
        error: function (jqXHR, textStatus, errorThrown) {
            alert('Error adding / update data');
        }
    });
}
</script>

Controller code :

public function sms() {
  $arr = $this->post('arr');
  foreach($arr as $ar) {
    echo $ar; // prints each element of the array.
  }
}

Not clear what specific problem is. "doesn't work" is a meaningless problem statement and doesn't suggest what part isn't working — charlietfl

You should use : $arr = $this->input->post('arr'); to retrieve post values, and if you expecting the returning result is a JSON type, then in server side you need to tweak the PHP code to return it by using echo json_encode($arrayVariable);, otherwise just omit dataType:json at AJAX properties.
