Question

我有注册表格。我看到一切都很好，并在控制台中正确显示，但是当成功插入记录以及显示成功消息时，我无法重定向页面。它也没有显示任何错误，如邮件已存在于数据库中。这是我的表格

<script>
$(document).ready(function () {
       $("#registFrm").submit(function () {
           var data = $("#registFrm").serialize();
           signupRecords(data);
           return false;
       });
       function signupRecords(data) {
           $.ajax({
               url: 'signupProcess.php',
               data: data,
               type: 'POST',
               dataType: 'json',
               success: function (data) {
                   if(data.code =="200" ) {
                    alert('success :  You have successfully signUp now please login');
                     setTimeout(function(){// wait for 5 secs(2)
                            location.reload(); // then reload the page.(3)
                       }, 5000); 
                  } else {
                      $(".display-error").html("<ul>"+data.msg+"</ul>");
                       $(".display-error").css("display","block");
                  }
              },
               error: function (jqXHR, exception) {
                console.log(jqXHR);
                // Your error handling logic here..
                }          
            });
           }
       });
</script>

这是我的signupProcess.php执行

if (empty($errorMSG)) {
$qry = $db->prepare('SELECT email FROM users WHERE email=?');
$qry->bindParam(1, $remail);
$qry->execute();

if ($qry->rowCount() > 0 ) {
    echo json_encode(['code' => 400, 'msg' => 'Email Already Exist']);
     exit;
} else {
     $stmt = $db->prepare("INSERT INTO users(name,email,password,mobile) VALUES(:name,:email,:password,:mobile)");
        $stmt->execute(array(':name' => $rname, ':email' => $remail, ':password' => $rpassword, ':mobile' => $rmobile));
        $affected_rows = $stmt->rowCount();
        if ($affected_rows == 1) {
            // starts the session created if login info is correct
            echo json_encode(['code' => 200, 'msg' => 'Successfully singUp']);
            exit;
        } else {
            echo json_encode(['code' => 400]);
            exit;
        }
} }else {
        echo json_encode(['code' => 404, 'msg' => $errorMSG]);
    }

                  } else {
                      $(".display-error").html("<ul>"+data.msg+"</ul>");
                       $(".display-error").css("display","block");
                  }
              },
               error: function (jqXHR, exception) {
                console.log(jqXHR);
                // Your error handling logic here..
                }          
            });
           }
       });
