codeigniter redirct function error

Question

I am working on codeigniter. I did the sql query to insert the data into the database.my query is running perfectly and is shown in the database table.

But i want to display message if my data is inserted into the table(like data inserted successfully).

here is my controller code:

public function insert(){

        $post=$this->input->post();
        unset($post['submit']);
       if($this->testimonial_model->insert_testimonial($post))
       {
           $this->session->set_flashdata('feedback',"Data inserted successfully.");
           $this->session->set_flashdata('feedback_class','alert-success');
       }else{
           $this->session->set_flashdata('feedback',"failed to add, Please Try again");
           $this->session->set_flashdata('feedback_class','alert-danger');
       }
       return redirect('testimonial_edit');

    }

here is my model code:

public function insert_testimonial($insert){
        return $this->db->insert('testimonial',$insert);
    }

Here is my view code and my view file name is testimonial_edit

<?php 
         if($feedback=$this->session->flashdata('feedback')):
             $feedback_class=$this->session->flashdata('feedback_class');
         ?>
         <div class="row">
             <div class="col-lg-6">
                 <div class="alert alert-dismissable <?php $feedback_class?>">
                 <?php $feedback?>
                 </div>
             </div>
         </div>
         <?php
         endif;
         ?>

Below this code my form code is there.

After filling form when i clicked on submit button the data is successfully inserted but it showing following error

404 Page Not Found

You can't redirect to a view file, so try adding a method to the controller which simply loads the view; then redirect to that method:

public function insert(){

    $post=$this->input->post();
    unset($post['submit']);
    if($this->testimonial_model->insert_testimonial($post))
    {
       $this->session->set_flashdata('feedback',"Data inserted successfully.");
       $this->session->set_flashdata('feedback_class','alert-success');
   }else{
       $this->session->set_flashdata('feedback',"failed to add, Please Try again");
       $this->session->set_flashdata('feedback_class','alert-danger');
   }
   redirect('current_controller_name/testimonial_edit');

}
/* add this function that you can redirect to, 
and which will load the view file of the same name */
function testimonial_edit(){
    $this->load->view('testimonial_edit');
}

As for your success message not displaying, try:

<?php if($this->session->flashdata('feedback')){ ?>
<div class="row">
    <div class="col-lg-6">
        <div class="alert alert-dismissable <?php echo $this->session->flashdata('feedback_class'); ?>">
        <?php echo $this->session->flashdata('feedback'); ?>
        </div>
    </div>
</div>

<?php } ?>
