Question

我希望能够使用AJAX登录来调用PHP文件。我的ajax和php代码看起来很好，并且当我做console.log（数据）时没有带来任何错误。问题是如果电子邮件和密码为真，表单发布时，php重定向（“my-account.php”）将不会执行。当字段留空时，我还没有完成验证部分。 escape_string是我在functions.php文件中创建的一个函数，用于防止sql注入，如果你想知道的话。

account.php代码

           $(document).ready(function(){

               $('#btnLogin').click(function(){

                   var email =  $("#email").val();
                   var password =  $("#password").val();


             var dataString = 'email='+email+ '&password='+password;

                    if(email=='' || password=='')
                    {
                    alert("Please fill all fields");
                    }

您无法从ajax请求重定向。要使此设置正常工作，您的ajax请求必须返回一个值，该值将告诉前端重定向。在您的AJAX成功回调中，您然后检查该值，然后

但这不是保护my-account.php的安全方式。如果你想重新定位登录，为什么你要使用AJAX？为什么不使用发布到my-account.php的表单，并在那里验证？
