如何在嵌入php的html表中为每一行添加复选框，并在数据库(Postgresql）中更新其值

我已经从数据库中获取了记录。它显示在html表上。但它仍然是不可编辑的模式。我想确保显示的记录完全正确，并在数据库中更新其布尔值。否则，应显示为未经批准的红色，即不正确。也许这很容易。但请帮我解决这个问题共享我的代码。

 <div class="login-signup-head">Edit Table</div>
    <table>
    <tbody>
         <thead>
              <tr class="tredit">
                <!-- <th width="10"></th> -->
                <th contenteditable="true"> Id </th>
                <th contenteditable="true"> University Id </th>
                <th contenteditable="true"> Name </th>
                <th contenteditable="true"> College Id </th>
                <th width="100"> </th>
              </tr>
            </thead>
            <tbody>
                          <?php 
         foreach($student_data as $row){
          ?>
            <tr class="tredit"> 
                <td><?php echo $row['id']; ?></td> 
                <td><?php echo $row['university_id']; ?></td> 
                <td><?php echo $row['name']; ?></td> 
                <td><?php echo $row['college_id']; ?></td> 
                <td><input type='button' class='editable' onclick="table_edit()" value='Edit'/>
                <input type='button' class='tabledelete' onclick="table_update()" value='Delete'></td> 
            </tr>
            <?php
        }
    ?>
     </div>
       </div>
       </div>
    <!--    </form> -->
       </div>  
    </div>
    </tbody>
         </table>

上面的代码是在控制器类中的函数的帮助下调用的，其代码如下：

 public function tableedit(){

          if($this->session->userdata('university_id')){
              /*if($this->input->server("REQUEST_METHOD") === "POST"){*/
                  // $data['user_id'] = $this->session->userdata('university_id');
                 /*$data['name'] = $this->input->post('college_name');
                 $data['college_id'] =$this->input->post('college_id');
             $insert = $this->home_model->addCollege($data);
              $data['success'] = 'college added successfully';
              }*/


              $user_id =  $this->session->userdata('university_id');
              $data['user_id'] = $user_id;
              $data['student_data'] = $this->home_model->table_data($user_id);
               $this->load->view('home/new-header',$data);
               // $data['get_social'] = $this->home_model->get_social();*/
               //  $this->load->view('socail', $data);
    //            if (isset($_POST['id'])) {
    //     echo json_encode($response);
    // }
               /*$this->home_model->update_university_password($user_id,$password);*/
               $this->load->view('home/left_university_sidebar',$data);
               $this->load->view('edit_table',$data);
               $this->load->view('home/footer');
          } else {
              $data['error'] = 'Table Cannot be viewed!';
              $this->load->view('home/header');
              $this->load->view('edit_table');
              $this->load->view('home/footer');
          }
      }

现在，上面的代码在模型类中被调用，即在哪里调用查询。

public function table_data($user_id) {
    $this->db->select('id,university_id,name,college_id');
       /*$this->db->where('university_id',trim($user_id));*/
       $this->db->from('college');
       $query = $this->db->get();
       return $query->result_array();
 /* $query = $this->db->query("SELECT id,university_id,name,college_id FROM college");
   $this->db->where('user_id',$university_id);
                   return $query->result_array();*/
}
