Я совсем новичок в codeigniter, и у меня есть проект, над которым я работаю, в котором мне нужно создать страницу редактирования для загрузки.

Вот что я попробовал, это модель страницы.

 public function update_cat($name, $cat_slug, $new_slug, $description){
    $upload_cat_id = $this->get_where($cat_slug);
    foreach ($upload_cat_id as $c_id):
        $id = $c_id->upload_cat_id;
    endforeach;
    $update_upload_cat = "UPDATE `upload_category` SET `name`= '". $name ."',`cat_slug`='". $new_slug ."',`description`='". $description ."' WHERE upload_cat_id = '". $id ."'";
    
    $this->db->trans_start();
    $this->db->query($update_upload_cat);
    $this->db->trans_complete();
    
    if($this->db->trans_status() === FALSE){
        $error = $this->db->error(); // Has keys 'code' and 'message'
        return $error;
    } else {
        return TRUE;
    }
}
 

а вот и контроллер

 public function edit($slug){
    $data['alert'] = $this->alert;
    $data['error'] = '';
    //Set Rules From validation
    $this->form_validation->set_rules('edit_name', 'Category Name', 'required');
    
    if($this->form_validation->run() === FALSE){
        $data['title'] = $this->site_info;
        $data['page_title'] = 'Update Upload Category';
        $data['category'] = $this->upload_cat_model->get_where($slug);
        $view_name = 'backendview/edit_upload_cat_view';
        $this->load_view($view_name, $data);
    } else {
        $name = $this->input->post('edit_name');
        $new_slug = url_title($this->input->post('edit_name'), 'dash', TRUE);
        $description = $this->input->post('description');
        $update_upload_cat = $this->upload_cat_model->update_cat($name, $slug, $new_slug, $description);
        if($update_upload_cat == TRUE){
            $this->alert = ' <div class="alert alert-success alert-dismissible">
                <button type="button" class="close" data-dismiss="alert" aria-hidden="true">amp;times;</button>
                <h4><i class="icon fa fa-check"></i> Successful!</h4>
                The category was successfully Updated.
              </div>'; 
            $this->index();
        } else {
            $this->alert = '<div class="alert alert-danger alert-dismissible">
                <button type="button" class="close" data-dismiss="alert" aria-hidden="true">amp;times;</button>
                <h4><i class="icon fa fa-ban"></i> Unsuccessful!</h4>
                An error occurred while we were trying to update the category. Hence, the category was NOT successfully Updated.
              </div>';
            $this->index();
        }
    }
}
