如何在PHP中使用post方法捕获表中每个用户的特定主ID?

php 来源:amit sutar 10次浏览

我对编程完全陌生。基本上我正在研究PHP和MySQL的crud操作。如何在PHP中使用post方法捕获表中每个用户的特定主ID?

下面是我从数据库中检索数据的代码。请注意,我使用隐藏输入字段来捕获每个用户的主键(id)。

<div class="table-responsive"> 
    <table id="datatable-buttons" class="table table-striped jambo_table bulk_action"> 
    <thead> 
     <tr class="headings">         
     <th class="column-title">Client Name</th> 
     <th class="column-title">PAN </th>  
     <th class="column-title">GST Registration Type </th>  
     <th class="column-title no-link last"><span class="nobr">Add</span> 
     </th>         
     </tr> 
    </thead> 
    <?php 
     $sql = mysqli_query($conn,'select * from customer_master'); 
     while ($row = mysqli_fetch_array($sql)) 
     {?> 
     <tbody> 
     <tr class="even pointer">          
      <td class=" "><?php echo $row['companyName'];?></td> 
      <td class=" "><?php echo $row['pan'];?></td>  
      <td class=" "><?php echo $row['gstTaxType'];?></td>     
      <td><input type="hidden" name="pid" value="<?php echo $row['customerId'];?>"></a> | <a type="" class="" data-toggle="modal" data-target="#edit_customer_profile"><i class="fa fa-pencil" aria-hidden="true"></i></a></td> 
     </tr>             
     </tbody> 
    <?php }?>         
    </table> 
</div> 

当点击data-target="#edit_customer_profile"秒模式将 只对特定customerId开放数据。

为此,我在第二个模态中使用了这个查询。

<?php $sql = mysqli_query($conn,'select * from customer_master'); 
             while ($row = mysqli_fetch_array($sql)) {?> 

因此,请帮助我检索选定用户的唯一数据。


===========解决方案如下:

您必须在SELECT语句中使用WHERE子句。一定要使用prepared语句来避免SQL注入。

这里从[PHP-文档]一个例子(http://php.net/manual/de/mysqli.prepare.php)改变你的需求:

<?php 
$mysqli = new mysqli("localhost", "my_user", "my_password", "world"); 

/* check connection */ 
if (mysqli_connect_errno()) { 
    printf("Connect failed: %s\n", mysqli_connect_error()); 
    exit(); 
} 

/* create a prepared statement */ 
if ($stmt = $mysqli->prepare("SELECT * FROM customer_master WHERE customerId=?")) { 

    /* bind parameters for markers */ 
    $stmt->bind_param("i", $_POST['customerId']); 

    /* execute query */ 
    $stmt->execute(); 

    /* bind result variables */ 
    $stmt->bind_result($customerId); 
    $stmt->bind_result($companyName); 
    $stmt->bind_result($pan); 
    $stmt->bind_result($gstTaxType); 

    /* fetch value */ 
    $stmt->fetch(); 

    /* close statement */ 
    $stmt->close(); 
} 

/* close connection */ 
$mysqli->close(); 
?> 

<div class="table-responsive"> 
    <table id="datatable-buttons" class="table table-striped jambo_table bulk_action"> 
     <thead> 
      <tr class="headings">         
       <th class="column-title">Client Name</th> 
       <th class="column-title">PAN </th>  
       <th class="column-title">GST Registration Type </th>  
       <th class="column-title no-link last"><span class="nobr">Add</span></th>         
      </tr> 
     </thead> 
     <tbody> 
      <tr class="even pointer">          
       <td class=" "><?php echo $companyName;?></td> 
       <td class=" "><?php echo $pan;?></td>  
       <td class=" "><?php echo $gstTaxType;?></td>     
       <td><input type="hidden" name="pid" value="<?php echo $customerId;?>"></a> | <a type="" class="" data-toggle="modal" data-target="#edit_customer_profile"><i class="fa fa-pencil" aria-hidden="true"></i></a></td> 
      </tr>             
     </tbody> 
    </table> 
</div>
