Question

I have created a comment library to handle comments all over my website developed by CI

I am adding comments using ajax so i have came up with practice to have the function located in MY_Controller that handle the ajax

public function comment_add()
    {
        echo $this->comments->add(); 
    }

and in AJAX Jquery code noting that category is one of controller names as any controller will havethe access to comment_add() found in parent controller

$('#myform').submit(function(e) {

    e.preventDefault();
    dataString=$("#myform").serialize();

  $.ajax({
    type:"POST",
    url: base_url+"snc/category/comment_add",
    data: dataString,
    success: function(data){
        $(data).hide().insertAfter('#inserAfterThis').slideDown('slow');
        $('#comment_new').val('');
        }
    }
  );
});   

and in my Comments library

public function add()
    { 
        $post_id=$this->get_post_id();
        $post_type=$this->get_post_type();

        if(!$post_id || !$post_type || !$this->user_id)
            return false;

        $id=$this->ci->comments_model->comment_add($this->user_id,$post_id,$post_type);
        if($id)
        {
            return $this->_markup($id);
        }
        else
            return false;
    }

and comments model

function comment_add($user_id,$post_id,$post_type)
{

    $data['comment_user_id']=$user_id;
    $data['comment_post_type']=$post_type;
    $data['comment_post_id']=$post_id;
    $data['comment_text']=$this->input->post('comment_new');

    $this->db->insert('comments', $data);

    if($this->db->affected_rows()>0)
        return $this->db->insert_id();
    else
        return false;

}

Problem is that Comment is inserted twice and as well in database twice, i have been tracin this for hours even with x-Debugg found that he go through echo $this->comments->add(); twice dunno why he would do that, thanks for your help
