Question

如何使用codeigniter删除评论，删除基于post_id的用户？例如：

我希望用户（admin）post_id（1）

删除评论（tester2）

这表我的数据库

＆＃13;

<table width="540" height="66" border="1" >
  <tr>
    <td><div align="center"><strong>post_id</strong></div></td>
    <td><div align="center"><strong>id_alat</strong></div></td>
    <td><div align="center"><strong>user</strong></div></td>
    <td><div align="center"><strong>namaalat</strong></div></td>
    <td><div align="center"><strong>commnet</strong></div></td>
    <td><div align="center"><strong>input_date</strong></div></td>
  </tr>
  <tr>
    <td><div align="center">1</div></td>
    <td><div align="center">001</div></td>
    <td><div align="center">admin</div></td>
    <td><div align="center">alat1</div></td>
    <td><div align="center">tester1</div></td>
    <td><div align="center">08/09/2015</div></td>
  </tr>
   <tr>
    <td><div align="center">2</div></td>
    <td><div align="center">002</div></td>
    <td><div align="center">admin</div></td>
    <td><div align="center">alat2</div></td>
    <td><div align="center">tester2</div></td>

查看，

<table width="540" height="66" border="1" >
  <tr>
    <td><div align="center"><strong>post_id</strong></div></td>
    <td><div align="center"><strong>id_alat</strong></div></td>
    <td><div align="center"><strong>user</strong></div></td>
    <td><div align="center"><strong>namaalat</strong></div></td>
    <td><div align="center"><strong>commnet</strong></div></td>
    <td><div align="center"><strong>input_date</strong></div></td>
    <td><div align="center"><strong>Action</strong></div></td>
  </tr>
  <tr>
    <td><div align="center">1</div></td>
    <td><div align="center">001</div></td>
    <td><div align="center">admin</div></td>
    <td><div align="center">alat1</div></td>
    <td><div align="center">tester1</div></td>
    <td><div align="center">08/09/2015</div></td>
    <td><div align="center"><a href="controller_name/controller_function?id=1&user=admin"><button>Delete</button></a></div></td>
  </tr>
   <tr>
    <td><div align="center">2</div></td>
    <td><div align="center">002</div></td>
    <td><div align="center">admin</div></td>
    <td><div align="center">alat2</div></td>
    <td><div align="center">tester2</div></td>
    <td><div align="center">08/09/2015</div></td>
    <td><div align="center"><a href="controller_name/controller_function?id=2&user=admin"><button>Delete</button></a></div></td>
  </tr> 
</table>

在Controller，

public function controller_function(){
   $id= $_GET['id'];
   $user = $_GET['user'];
   if($user == "admin"){
     $this->load->model('model_name/model_function');
     $data = $this->model_function->delete_comment($id);
     if(data == true){
       echo "Deleted Successfully";
     }
   }
}

在模特，

public function delete_comment($id){
  $this->db->where('post_id',$id);
  $sql = $this->db->delete('Your_Comment_Table_Name');
  ($sql)? return TRUE : return False;
}

我希望这会对你有所帮助
