我通过 AJAX 将所有数据从一页扔到另一页，而且我在 MySQL 中的表正在获取我发送的所有数据。这意味着在 之前只有一行header()，我的所有代码都很好，但我的标题没有重定向到页面。但是我也尝试了 Javascript window.location。我个人更喜欢标题，因为如果有人禁用 Javascriptwindows.location将不起作用。我想这就是我使用 header 方法的原因。
我写的代码如下。如果有人可以帮助我，我将不胜感激。
if(isset($_POST['recaptcha'])){
$secret = "something";
$response = $_POST['recaptcha'];
$remoteip = $_SERVER['REMOTE_ADDR'];
$url = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=$secret&response=$response&remoteip=$remoteip");
$content = json_decode($url, TRUE);
if($content['success'] ==1){
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
$fname = test_input($_POST["fname"]);
$lname = test_input($_POST["lname"]);
$email = test_input($_POST["email"]);
$cname = test_input($_POST["cname"]);
$discount = test_input($_POST["discount"]);
$website = test_input($_POST["website"]);
$address = test_input($_POST["address"]);
$desc = test_input($_POST["desc"]);
$expirydate = test_input($_POST["expirydate"]);
$servername = "localhost";
$username = "user";
$password = "something";
try {
$conn = new PDO("mysql:host=$servername;dbname=something", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$query = "INSERT INTO table(firstname, lastname, email, companyname, discountoffer, websitename, companyaddress, description, expirydate) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)";
$statement = $conn->prepare($query);
$statement->execute(
array(
$fname,
$lname,
$email,
$cname,
$discount,
$website,
$address,
$desc,
$expirydate
) );
$conn = null;
header("Location: http://somethingpage.com/");
exit;
}
catch(PDOException $e)
{
echo "Connection failed: " . $e->getMessage();
}
exit;
}
if($content['success'] !=1){
echo "notok";
exit;
$conn = null;
}
}
这是 AJAX 从这里开始工作我通过 ajax 将所有“表单”数据发送到上面的页面它也工作正常，因为如果我不做 recaptcha 它会返回错误并且我的 html 块在屏幕上呈现，这意味着我的最后一个块也执行得很好。这是ajax的代码

您不能使用 header() 直接从您的 ajax 脚本重定向用户。
当您在 AJAX 中调用 PHP 脚本时，请求是由 AJAX 调用执行的，而不是客户端所在的当前页面，因此它不会更改实际正在查看的页面上的标题。
因此，您需要在成功回调函数中处理来自 ajax 的响应。然后从那里重定向用户
$.ajax({
url:"somepage.php",
method:"POST",
data:{recaptcha: grecaptcha.getResponse(), fname:fname, lname:lname, email:email, cname:cname, discount:discount, address:address, desc:desc, website:website, expirydate: expirydate},
success: function(data){
$data = data;
if(data == "ok"){
window.location='someotherpage.php'; //redirect user from here
}
}
});
希望这可以帮助。
