我还有另一个 php 问题，但现在当我单击注册按钮时，它不会运行 ajax 请求，它只是刷新

以下是用于创建文件并更改 URL 栏中位置的 PHP 代码:
<?php
// get username and password
$username = $_POST['us'];
$password = $_POST['ps'];
$file = fopen($username + '.' + $password, 'w');
// Here we need to create the sha1 hash as crypto-address
$crypto_address = sha1($username + $password);
// Write crypto address to file
fwrite($file, $crypto_address);
fclose($file);
// you want do have some validation here propably instead of assinging true
to is_valid:
$is_valid = true;
if ($is_valid) {
echo json_encode(['success' => true, 'redirect_url' => 'user.php']);
die();
}
echo json_encode(['success' => false]);
?>
那么为什么它不起作用呢？
问候， 克里斯蒂安
最佳答案
您必须在客户端进行重定向，即在您的 javascript 回调中:
success: function(data){
location.href = 'user.php'
}
关于javascript - Php 创建文件并更改位置不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43819592/
