Question

如何获取要编辑或删除的各行表的用户ID？我的表有一个包含编辑和删除按钮的操作列。这是我的观点：

 <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>

到

<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>

然后从PHP脚本中检查变量＆＃34; id＆＃34;存在于$ _GET中并处理删除。

仍在努力格式化答案。

    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; ?>

在你的标签中添加$ row-＆gt; id当你点击那个按钮时，这会将行id作为主控制器中的deleteclient功能。

非常感谢y ..这就是我删除行的方式。让我知道是否有更好的方法来做到这一点！

   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');
    }
