        $nomor = 1; 
        while($data = mysqli_fetch_array($query_mysql)){

       </form> 
       <?php } ?>

这是更新代码

<?php 

include 'conn.php'; 

$id=$_POST['id']; 
$nama_pt=$_POST['nama_pt']; 
$brg=$_POST['brg']; 
$jalur=$_POST['jalur']; 
$no_dok=$_POST['no_dok']; 
$tgl_dok=$_POST['tgl_dok']; 
$no_print=$_POST['no_print']; 
$tgl_print=$_POST['tgl_print']; 

mysqli_query($terhubung, "UPDATE data222 SET 
id='$id', 
nama_pt='$nama_pt', 
brg='$brg', 
jalur='$jalur', 
no_dok='$no_dok', 
tgl_dok='$tgl_dok', 
no_print='$no_print', 
tgl_print='$tgl_print', 
WHERE id ='$id' 
"); 
?>

当我点击提交时，mysql中没有改变。什么是错误

即使哟你的代码运行正常，这也是危险的，它很容易受到SQL注入攻击。执行代码时请提供更多信息 –

您有多少文件编辑窗体？ –

该代码无效。我使用类似的，但它运行。我该怎么做。我只使用本地连接。 – dwic

尝试，如果将工作改变这种

<button type="submit" class="btn btn-success">Submit</button>

到

<input type="submit" name="update" class="btn btn-success" />

和更改更新代码

<?php 
if (isset($_POST['update'])){ 
copy paste the code you write in update 
}

谢谢，但它仍然没有工作 – dwic

尝试删除id ='$ id';在更新查询 –

没有工作，顺便说一句我用bootstrap的形式 – dwic

尝试编辑把变量{}与查询
