I saw an example in native PHP which allows inline editing or records and also updates them.
[PHP Inline Editing](http://phppot.com/php/php-mysql-inline-editing-using-jquery-ajax/) Now as per this code i have a ajax function which calls the update file whenever the content is updated below is the script :

```
    <script src="http://code.jquery.com/jquery-1.10.2.js"></script>
    <script>
    function showEdit(editableObj) {
        $(editableObj).css("background","#FFF");
    } 

    function saveToDatabase(editableObj,column,id) {
        $(editableObj).css("background","#FFF url(<?php echo site_url('img/loaderIcon.gif');?>loaderIcon.gif) no-repeat right");
        $.ajax({
            url: "<?php echo(site_url('Inlinedit/updateDb'));?>",
            type: "POST",
            data:'column='+column+'&editval='+editableObj.innerHTML+'&id='+id,
            success: function(data){
                $(editableObj).css("background","#FDFDFD");
            }        
       });
    }
    </script>

```

THe Model :

```
public function inline( $column, $editval, $id )
        {
            $result = mysql_query("UPDATE users set $column = $editval WHERE  id=$id");
        }

```

the Controller:

```
<?php

```

class Inlinedit extends Admin\_Controller {

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

      public function updateDb()
      {
             $column = $this->input->post('column');
             $editval = $this->input->post('editval');
             $id = $this->input->post('id');

             $this->load->model('user_m');                     
             $this->user_m->inline( $column, $editval, $id );

             return;
      }

```

}
