PHP-SQL-DELETE查询不起作用
瞄准 删除选中ID的所有数据 问题 数据不会被删除 错误 开发人员控制台中未提示任何错误 作品描述 根据我对codes函数的理解,检索用户ID delete_userID,然后使用mysqli_real_escape_string$conn,$_POST['delete_userID']将其传递到$delete_userID;。但是我不明白为什么删除查询不起作用。我在网上看到了几个关于这个的问题,其中一些是因为缺少数据库代码mysql\u select\u dbdata2017,$conn;但这似乎不是我的问题。此外,我还将其设置为一旦单击了输入按钮,它将发送一个删除调用,并且if语句将检查按钮是否已单击以及调用是否已收到。除了检索用户ID外,还通过使用JavaScript函数传递了要删除的用户ID,如下所示PHP-SQL-DELETE查询不起作用,php,mysql,sql,Php,Mysql,Sql,瞄准 删除选中ID的所有数据 问题 数据不会被删除 错误 开发人员控制台中未提示任何错误 作品描述 根据我对codes函数的理解,检索用户ID delete_userID,然后使用mysqli_real_escape_string$conn,$_POST['delete_userID']将其传递到$delete_userID;。但是我不明白为什么删除查询不起作用。我在网上看到了几个关于这个的问题,其中一些是因为缺少数据库代码mysql\u select\u dbdata2017,$conn;但这

delete_用户ID是通过JavaScript函数传入的,如下所示
function bindList() {
var $table = $('#eventsTable');
$table.bootstrapTable({

尝试使用PDO,因为最新的PHP版本不推荐使用MySQL DB连接。 首先,您必须声明表单方法和操作,然后还要关闭它 请尝试下面的代码
<?php
$config = array(
'host' => 'localhost',
'username' => 'db_username',
'password' => 'db_password',
'dbname' => 'data2017'
);
$db = new PDO('mysql:host=' . $config['host'] . ';dbname=' . $config['dbname'], $config['username'], $config['password']);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
if(isset($_POST['delete_userID'])){
$delete_userID = $_POST['delete_userID'];
// No need to use mysqli_real_escape_string when we using prepared statements
$stmt = $db->prepare("DELETE FROM pha_user WHERE id = '$delete_userID' ");
$stmt->execute();
if($stmt){
header("Location:appropriate_page.php?del_success");
}else{
header("Location:appropriate_page.php?del_failure");
}

我们可以看更多的元素吗?delete_userID里面没有值。@Scuzzy我没有在里面放一个,我意识到那是我的problem@saddam该值由javascript函数传入。我将编辑我的问题。但是Riccardo指出我没有,这是我的问题。我们可以看看更多的元素吗?delete_userID里面没有值。@Scuzzy我没有在里面放一个,我意识到那是我的problem@saddam该值由javascript函数传入。我将编辑我的问题。但是里卡多指出,我没有这个,这是我的问题。非常感谢里卡多!!!我刚试了一下,效果很好=圣诞快乐,新年快乐:也祝你圣诞快乐。非常感谢你,里卡多!!!我刚试了一下,效果很好=圣诞快乐,新年快乐:也祝你圣诞快乐。谢谢你的帮助,我回去工作的时候一定要试试。圣诞快乐,新年快乐:不客气。使用PDO bcz现在一天服务器也会反复提示升级您的php版本。注意并感谢您的建议。我对PHP非常陌生,我会仔细阅读=d感谢你的帮助,我回去工作后会尝试一下。圣诞快乐,新年快乐:不客气。使用PDO bcz现在一天服务器也会反复提示升级您的php版本。注意并感谢您的建议。我对PHP非常陌生,我将阅读关于=D的文章
