javascript - 尝试使用 ajax 将数据发送到 OOP 类

Question

我试图从 HTML 表单 -> ajax -> 实例 -> oop 类文件发送包含用户名、密码等的数据。

但我不确定我的方法是否正确...

它以 index.php 上的表单开始

 <!-- Formular for signing up -->
 <form method="post">
    <div class="form-group">
        <label> Username </label>
        <input type="text" class="form-control" name="newusername"> 
    </div>    

    <div class="form-group">
        <label> Password </label>
        <input type="password" class="form-control" name="newpassword"> 
    </div>

    <div class="form-group">
        <label> Your club </label>
        <input type="text" class="form-control" name="newclub"> 
    </div>   

   <input type="button" id="btn-reg" class="btn btn-success" value="Sign up!">

</form> 

然后它通过我的脚本文件和 ajax

$(document).ready(function () {

console.log('Script loaded...');
$("#btn-reg").on("click", reg);      


// Function for registrate of new users
function reg(newusername, newpassword, newclub) {
    $.post('classCalling.php', {
        newusername: 'newusername',
        newpassword: 'newpassword',
        newclub: 'newclub'
    });
};
});

然后我的数据将转到一个页面，classCalling.php，我在其中实例化我的类

    ?php

     include("class/userClass.php");
     include("class/pagesClass.php");



                // Creating instance of the class userClass.php
                 $user = new User();




                // Defining variables
                $newusername = $_POST['newusername'];
                $newpassword = $_POST['newpassword'];
                $newname = $_POST['newclub'];

                // Password hash
                $hashpassword = sha1($newpassword);

                $user->newUsers($newusername, $hashpassword, $newname);         


 ?>

最后是我的 OOP 类(class)，但我还没有走到这一步

 public function newUsers($newusername, $newpassword, $newclub) {

        // Using prepared statement to prevent mysql injections.
        $stmt = $this->db->prepare("INSERT INTOusers(username,password, club)VALUES(?, ?, ?);");
        $stmt->bind_param("sss", $newusername, $newpassword, $newclub);

        if($stmt->execute()) {
            echo "<h3 class='usercreated'>Användare skapad</h3>";
            } else {
                echo "<h3 class='usercreated'> Gick ej att skapa användare</h3>";
            }
}

我收到这些错误通知:Undefined index: newusername in/Applications/MAMP/htdocs/web 2.0/projektet/classCalling.php on line 13

我认为错误是因为您没有将任何参数传递给 reg。

尝试将表单值传递给 reg 函数它会没问题
