This article will give an example of how to use thinkphp to achieve data deletion and batch deletion.
Expected renderings:

Forgive the blogger for processing the photos so carelessly. . .
Still split through MVC mode:
First is the view part:

<form action="__MODULE__/Admin/User/del" method="get">
       <tr>
        <th width="4%"><input type="checkbox" name="checkbox10" id="checkbox10"></th>
        <th width="13%">用戶名</th>
        <th width="10%">真實姓名</th>
        <th width="13%">手機號</th>
        <th width="21%">郵箱</th>
        <th width="11%">注冊時間</th>
        <th width="17%">操作</th>
       </tr>
      <volist name = &#39;adminUsers&#39; id = &#39;vo&#39;>
       <tr>
        <td><input type="checkbox" name="id[]" id="checkbox" value="{$vo.id}">
        <td>{$vo.username}</td>
        <td>{$vo.realname}</td>
        <td>{$vo.telphone}</td>
        <td>{$vo.email}</td>
        <td>{$vo.resgistertime}</td>
        <td><a href="__MODULE__/Admin/User/modi/id/{$vo.id}">修改</a><a href="#"></a> <a href="__MODULE__/Admin/User/del/id/{$vo.id}">刪除</a></td>
      </tr>
      </volist>
       
       
      </table>
     </div>
     <div class="input-group pull-left form">
        <button type="submit" class="btn btn-danger ">刪 除</button>
      </div>
      </form>

Still uses the method of passing values ????from the form, but this time no verification is required because the data is directly processed rather than letting the user input data, so There is no need to worry about the illegality of the data because the model part is omitted. A more clever method adopted here is to define name as an array, and in the controller, you only need to judge whether the incoming id is an array, saving you the trouble of writing it separately.
The next part is the controller part

public function del(){
  // $name = getActionName();   //作為公共的函數(shù)使用時添加
  $adminUsersModel = D("adminUsers"); //獲取當期模塊的操作對象 
  $id = $_GET['id'];  //判斷id是數(shù)組還是一個數(shù)值 
  if(is_array($id)){   
    $where = 'id in('.implode(',',$id).')';  
  }else{  
   $where = 'id='.$id; 
  }  //dump($where); 
  $list=$adminUsersModel->where($where)->delete();  
  if($list!==false) {
     $this->success("成功刪除{$list}條！", U("Admin/User/lists")); 
  }else{   
    $this->error('刪除失敗！');  
  } 
}

The above is the entire implementation process. I wonder if you guys have gotten this relatively clever method?
