我有一个显示表单的 registraion
php 类,当单击注册按钮时,调用登录 javascript 文件中的函数。此文件使用 ajax
将数据发布到 index.php 文件。我的 index.php
文件无法访问此数据,尽管发布成功(调用警报时 ajax 成功为真)。
Login.js
var loginData, urlPath;
// Allow users to log in or register
function Login() {
loginData = "username=" + $("#usernameField").val() + "&email=" + $("#emailField").val() + "&password=" + $("#passwordField").val();
urlPath = "../index.php?action=register";
// Send the login/registration data to database
$(document).ready(function() {
$.ajax({
type: "POST",
url: urlPath,
data: loginData,
success: function (result) {
alert("success");
}
})
})
}
index.php
<?php
require_once("Model/model.php");
require_once("Controller/controller.php");
require_once("View/view.php");
$model = new Model();
$view = new View();
$controller = new Controller($model, $view);
$controller->Begin();
// Client wants to register
if(isset($_GET['action'])) {
if($_GET['action'] == "register") {
echo '<script type="text/javascript">alert("hello")</script>';
}
}
?>
最佳答案
您使用了 ajax 的 POST 方法。所以也像下面这样以 POST 方式发送数据:-
// Send the login/registration data to database
$(document).ready(function() {
var username = $("#usernameField").val();
var email = $("#emailField").val();
var password = $("#passwordField").val();
$.ajax({
type: "POST",
url: "../index.php",
data: {"username":username,"email":email,"password":password,"action":"register"},
success: function (result) {
alert(result);//check the change
}
});
});
然后在 php 端将 GET
更改为 POST
:-
<?php
require_once("Model/model.php");
require_once("Controller/controller.php");
require_once("View/view.php");
$model = new Model();
$view = new View();
$controller = new Controller($model, $view);
$controller->Begin();
// Client wants to register
//single condition can do the job and use POST instead of GET
if(isset($_POST['action']) && $_POST['action'] == "register" ) {
echo "hello"; //check the change
}
?>
注意:- 请也注意注释。(添加到代码中)
