Codeigniter PHP检查

Question

我怎样才能用不同的表格检查代码。

如果表中已有数据，STAFF用户只允许编辑

否则用户允许在该编辑后永久插入。

关于代码注释的更多解释 希望能够理解。谢谢你掌握。

控制器

public function Test()
{

   $d['checking'] = $this->db->query("SELECT status,amount,br_loc FROM account");
   $d['test'] = $this->db->query("SELECT br_loc FROM staff");

    $this->load->view('Account/global/header');
    $this->load->view('test',$d);
    $this->load->view('Account/global/footer');
}

查看

 <table class="table table-hover table-condensed">
        <thead>
          <tr>
            <th></th>
            <th>Code</th>
          </tr>
        </thead>
        <tbody>
    <?php
      foreach($checking as $c)
        {   
        foreach($data->result_array() as $row)  // data select from table ACCOUNT and show as array..From table ACCOUNt data will insert to table STAFF. 
        {       
        ?>
          <tr>
            <td><?php echo $row['br_loc'];?></td> <!--CHECKING -if data already insert in table staff show button edit else button save to insert-->
            <?php if($c['status'] == 'save')
            { ?>
            <td><button type="button" value ='Edit'  class="btn btn-primary" id="edit<?php echo $row['br_loc'];?>" >Edit</button></td>
             <?php  }
            else
            { ?>
            <td><button type="button" value ='Save'  class="btn btn-primary" id="save<?php echo $row['br_loc'];?>" >save</button></td>
           <?php  } ?>
          </tr>
         <?php
              }
            }
         ?>
       </tbody>
    </table>

结果

保持循环和重复。

除非我遗漏了一些东西，但我觉得你的循环错了

您在控制器中设置了查询，但在视图中您没有接触到结果....

这样做 $ checking-＆GT; result_array（） $测试 - ＆GT; result_array（）

 <table class="table table-hover table-condensed">
    <thead>
      <tr>
        <th></th>
        <th>Code</th>
      </tr>
    </thead>
    <tbody>
<?php
    foreach($test->result_array() as $row)  // data select from table ACCOUNT and show as array..From table ACCOUNt data will insert to table STAFF. 
    {       
    ?>
      <tr>
        <td><?php echo $row['br_loc'];?></td> <!--CHECKING -if data already insert in table staff show button edit else button save to insert-->
        <?php 
        $tempStatus = null;
        foreach($checking->result_array() as $c){
            if($c['br_loc'] == $row['br_loc']){
                $tempStatus = $c['status'];
            }
        }
        if($tempStatus == 'save')
        { ?>
        <td><button type="button" value ='Edit'  class="btn btn-primary" id="edit<?php echo $row['br_loc'];?>" >Edit</button></td>
         <?php  }
        else
        { ?>
        <td><button type="button" value ='Save'  class="btn btn-primary" id="save<?php echo $row['br_loc'];?>" >save</button></td>
       <?php  } ?>
      </tr>
     <?php
          }
    ?>
   </tbody>
</table>

所以我猜你想要这样的东西吗？ 同样对于codeigniter我会推荐模板插件，它会让你的生活更轻松，而不必加载大量的观点。
