所以我试图创建一个模态，用于从显示的表格中编辑用户（选中）。
我已经尝试了两种不同类型的提交来使这个过程起作用，但首先是我的PHP代码..（是Ik，清理变量，它将很快添加）
if ($_POST['edituser']) {
$uid = strip_tags($_POST['edituser']);
if (isset($_POST['email'])) {
$newemail = $_POST['email'];
mysqli_query($con, "UPDATE `users` SET `email` = '$newemail' WHERE `uid` = '$uid'") or die(mysqli_error($con));
}
if (isset($_POST['usergroup'])) {
$newusergroup = $_POST['usergroup'];
mysqli_query($con, "UPDATE `users` SET `usergroup` = '$newusergroup' WHERE `uid` = '$uid'") or die(mysqli_error($con));
}
if (isset($_POST['paypal'])) {
$newpaypal = $_POST['paypal'];
mysqli_query($con, "UPDATE `users` SET `paypal` = '$newpaypal' WHERE `uid` = '$uid'") or die(mysqli_error($con));
}
if (isset($_POST['avatarlink'])) {
$newavatarlink = $_POST['avatarlink'];
mysqli_query($con, "UPDATE `users` SET `avatarlink` = '$newavatarlink' WHERE `uid` = '$uid'") or die(mysqli_error($con));
}
if (isset($_POST['job'])) {
$newjob = $_POST['job'];
mysqli_query($con, "UPDATE `users` SET `job` = '$newjob' WHERE `uid` = '$uid'") or die(mysqli_error($con));
}
if (isset($_POST['aboutme'])) {
$aboutme = $_POST['aboutme'];
mysqli_query($con, "UPDATE `users` SET `aboutme` = '$newaboutme' WHERE `uid` = '$uid'") or die(mysqli_error($con));
}
header("Location: /staff/users?success=true");
die();
}
现在这些是我尝试过的两种提交方法......

$ug = $userRow['usergroup'];
$result = mysqli_query($con, "SELECT * FROM `users`") or die(mysqli_error($con));

使用此方法（上图），没有任何反应...页面只是刷新。

尝试此方法（上图）时，页面和通知显示..但数据库中没有任何更新。
感谢您的帮助：）

正如评论中所提到的，您的代码目前非常不安全。您绝对应该使用parametrised queries来防止人们弄乱您的数据库，并protect yourself from xss attacks以防止您的网站成为恶意软件。
但问题的答案是给输入字段name attribute in addition to an id。
目前，您的表单未发布任何数据 - 因此没有任何更改。
