通过 $ID 从数据库中删除用户不起作用
[英]Delete user from Database by $ID not working
问题描述
我无法使此代码正常工作。 这是我的 manageclients.php 如何将单击的用户 ID 传递给 URL，以便我可以执行删除查询？ 当我执行此操作时，没有任何反应，如果我将 if 语句移到表查询下方，它会起作用，但它会删除我所有的表行。
<?php
if (isset($_POST['AddUsr']))
{
$new_username = $_POST['add_username'];
$new_password = $_POST['add_password'];
$new_vorname = $_POST['add_vorname'];
$new_nachname = $_POST['add_nachname'];
$new_email = $_POST['add_email'];
$new_handy = $_POST['add_handy'];
$new_admin = $_POST['add_admin'];
// if (empty($_POST['username']) || empty($_POST['password']) || empty($_POST['vorname']) || empty($_POST['nachname']) || empty($_POST['Email']) || empty($_POST['handy']) || empty($_POST['admin']))
// {
// $show -> showError("Bitte alle Felder ausfüllen"/*isset($_POST['Enabled']) ? "1" : "0"*/);
// }
// if
{
$SQLCheckUser = $odb -> prepare("SELECT * FROM `Account` WHERE `email` = :email");
$SQLCheckUser -> execute(array(':email' => $_POST['add_email']));
$SQLCheckUser = $SQLCheckUser -> fetchColumn(0);
if ($SQLCheckUser > 0)
{
$show -> showError('Benutzer bereits in der Datenbank');

尝试这个
$stmt = $odb->prepare("DELETE FROM Account WHERE id=? ");
$stmt->execute(array($_GET['DeleteID']));

你必须设置你的变量 $ID
$ID = $_GET['DeleteID'];
如果user_id和post_id相同，如何从数据库中删除一个赞？
