Codeigniter如何編輯或刪除表中的行

Question

如何獲取表格各行的用戶ID以進行編輯或刪除？ 我的表有一個具有編輯和刪除按鈕的操作列。 這是我的看法：

 <table class="table table-striped">
   <tr>
     <td>First Name</td>
     <td>Last Name</td>
     <td>Address Name</td>
     <td>Action</td>
   </tr>
  <?php foreach($results as $row): ?>
    <tr>
      <td><?php echo $row->first_name; ?></td>
      <td><?php echo $row->last_name; ?></td>
      <td><?php echo $row->address; ?></td>
      <td><a href="" class="btn btn-info">Edit</a>
      <a href="<?php echo base_url()."main/deleteclient" ?>"                                       
          class="btn btn-danger"
              onclick="return confirm
              ('Are you sure  to Delete?')">Delete</a></td>

                </tr>
                 <?php endforeach; ?>

 </table> 

Answer 1

更改

<a href="<?php echo base_url()."main/deleteclient" ?>"                                       
          class="btn btn-danger"
          onclick="return confirm
          ('Are you sure  to Delete?')">Delete</a>

至

<a href="<?php echo base_url()."main/deleteclient?id=".$row->id ?>"                                       
          class="btn btn-danger"
          onclick="return confirm
          ('Are you sure  to Delete?')">Delete</a>

然后從您的PHP腳本中檢查$ _GET中是否存在變量“ id”並處理刪除。

仍在格式化答案。

    As like you are getting other table values like first name and last name there should be (if you gave an primary id) an id for each row. So you can get that id for each row and send it to your delete function by URL.

     <?php foreach($results as $row): ?>
           <tr> 

                <td><?php echo $row->first_name; ?></td>
                <td><?php echo $row->last_name; ?></td>
                <td><?php echo $row->address; ?></td>
                <td><a href="" class="btn btn-info">Edit</a>

<a href="<?= base_url();?>main/deleteclient/<?= $row->id;?>"></a>                                      
                  class="btn btn-danger"
                  onclick="return confirm
                  ('Are you sure  to Delete?')">Delete</a></td>

                    </tr>
                     <?php endforeach; ?>

在您的標簽中添加$ row-> id，當您單擊該按鈕時，會將行ID帶到主控制器中的deleteclient函數中。

非常感謝你們..這就是我刪除行的方式。 讓我知道是否有更好的方法！

   view: 

    <table class="table table-striped">
      <tr>
       <td>First Name</td>
        <td>Last Name</td>
        <td>Address</td>
         <td>Citizen Number</td>
       <td>Action</td>
   </tr>
    <?php foreach($results as $row): ?>
   <tr> 

   <td><?php echo $row->first_name; ?></td>
   <td><?php echo $row->last_name; ?></td>
   <td><?php echo $row->address; ?></td>
  <td><?php echo $row->citizen_no; ?></td>
  <td><a href="" class="btn btn-info">Edit</a> 
  <a href="<?php echo base_url().
  "main/deleteclient?id=".$row->client_id ?  >" 
  class="btn btn-danger" 
 onclick="return confirm('Are you sure to Delete?')">Delete</a></td>

 </tr>
<?php endforeach; ?>

 </table>  

    controller:
      public function deleteclient(){
     if(isset($_GET['id'])){
        $id=$_GET['id'];
        $this->load->model('members');
        $this->members->row_delete($id);
        redirect('main/viewclient');}
 }
   model:
  public function row_delete(){
        $id=$_GET['id'];
        $this->db->where('client_id', $id);
        $this->db->delete('client');
    }
