它直接进入show_all.php，不给出任何错误，但不做任何更改 您没有在$id左右结束报价： 换句话说，它应该是：
WHERE
ID = '" . $id . "'";
在更改标头位置之前，当您使用echo输出时，标头重定向将永远无法工作 因此，您可以：
if(!mysqli_query($con,$query)){
echo 'Error' . mysqli_error($con); // print your error to the screen
} else{
header("Location: show_all.php"); // do nothing as you've already echo'd further up the script
}
主要错误来自于此
$_POST['idd']
WHERE
ID = '" . $id . "' ";
^---you missed single quote here
echo $photo = mysqli_real_escape_string($con, $_FILES['myfile']['name']);
echo $id = mysqli_real_escape_string($con, $_POST['idd']);
ID = " . $id . "'";
有错误吗？@AbhikChakraborty错误在问题的开头。哪一行是第13行？@Barmar，没有，注意和错误之间有很大的不同。显式命令或php设置可以忽略通知。现在我发现了错误，但当它运行时，它会进行任何更改。但它没有给出任何错误@ABHIKChakrabortyth这解释了MySQL错误，但不是PHP未定义的索引错误。我的猜测是，您在表单中看到的内容与服务器端的预期不匹配。它仍然没有更新：我认为输出都是为了调试，所以最好不要重定向-在一些评论中，他说它没有更新数据库。重定向与此无关。以下是输出：注意：第13行C:\xampp\htdocs\taugamma\update\u member.php中的未定义索引：myfile注意：第1行C:\xampp\htdocs\taugamma\update\u member.php中的未定义索引：idd
