在实现 jquery 表单验证并使用 function btn_onclick()
{ window.location.href = "http://localhost/loginprivate.php";}
index.php 重定向到 loginprivate.php 后,我的 webapps php 脚本将不会执行。用户通过 javascript 函数和 window.location.hrefindex.php 重定向到 loginprivate.php,你可以在这里看到。在第一次页面加载后,页面再次加载 <script src="loadagain.js"></script> 这也工作正常。

现在的问题是,如果我单击提交按钮,php 代码将不会执行,我可以看到,因为没有创建 cookie,并且用户被重定向到 index.php

我的 php 代码:

    if(isset($_POST["submit"]))
{
$hostname='localhost';
$username='root';
$password='';

unset($_POST['password']);
$salt = '';
for ($i = 0; $i < 22; $i++) {
$salt .= substr('./ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789', mt_rand(0, 63), 1);
}
$_POST['password'] = crypt($_POST['password'],'$2a$10$'.$salt);
$new = 0;
try {
$dbh = new PDO("mysql:host=$hostname;dbname=search",$username,$password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // <== add this line
$sql = "INSERT INTO users (username, password)
VALUES ('".$_POST["username"]."','".$_POST["password"]."')";
if ($dbh->query($sql)) {
echo "New Record Inserted Successfully";
}
else{
echo "Data not successfully Inserted.";
}
$new = $dbh->lastInsertId();
$dbh = null;
}
catch(PDOException $e)
{
echo $e->getMessage();
}
if ($new > 0)
{

$t = time() + 60 * 60 * 24 * 1000;
setcookie("username", $_POST['username'], $t);
setcookie("userid", $new , $t);
}
else
{

}
}

我的 html 代码:

return false; // for demo

});

最佳答案

根据您的评论,我的屏幕上现在只有这个“Array ( )”。这意味着您没有向 PHP 发布任何内容 页面。

那只是因为,您将控件重定向PHP页面,而不是提交表单。

因此,您可以使用 jQuery 验证代码,并在成功验证 时执行 ajax post 请求而不是移动控件。window.location.href = "http://localhost/lak/main.php";

不是转移控制,而是做一个post

$.ajax({
type: 'post',
url: 'loginprivate.php' //url where you want to post the stuff.
data:{
username: 'someUserName',
password: 'xxxxxxxxxxxx'
},
success: function(res){
//here you will get res as response from php page, either logged in or some error.
//and if you're logged in successfully, redirect here now.
}
});

希望这会有所帮助。
