I'm stuck on a problem with updating image. I did upload the multiple image and inserted in database but I can not override these images in database or my upload folder how can I override the images in my upload folder and my database.

I do multiple image upload in CodeIgniter; the same code is used to update the the multiple image but in the update time:

```
public function edit_package($package_id){

    $pname      = $this->input->post('pname'); 
    $pdur       = $this->input->post('pdur');
    $pdelprice  = $this->input->post('pdelprice');
    $price      = $this->input->post('price');
    $pcat       = $this->input->post('pcat');
    $pc         = $this->input->post('pc'); 
    $ploc       = $this->input->post('ploc');
    $pcat       = $this->input->post('pcat');
    $accom1     = $this->input->post('accom1');
    $accom2     = $this->input->post('accom2');
    $accom3     = $this->input->post('accom3');
    $accom4     = $this->input->post('accom4');
    $accom5     = $this->input->post('accom5');
    $accom6     = $this->input->post('accom6');

    // Displaying Errors in view

    $this->form_validation->set_error_delimiters('<span style="color:red;">', '</span>');
