将PHP电子邮件添加到具有通过AJAX呼叫终止代码发送的信息的文件中

Question

我创建了更新用户组级别（权限级别）的代码。 我通过AJAX将选定的ID和组级别发送到名为user_update_group的php文件。 在尝试将PHP电子邮件添加到同一文件之前，更新用户的组＃效果很好。 我这样做是因为我已经从数据库中获取了该用户的信息，所以我认为这是最好的方法。

但是，在添加电子邮件时会破坏代码。 我的php文件中是否有某些东西显然可以杀死它，或者我不能这样做吗？ 我试图从带来的ID中SELECT用户表中的所有数据，然后使用与其他查询相同的按钮向他们发送电子邮件。 我的php电子邮件是我在此处添加的php文件的第二部分。 我添加了所有这些代码以显示我要执行的操作。

<?php
$con2 = mysqli_connect("localhost", "root", "", "db");
$run2 = mysqli_query($con2,"SELECT * FROM user_requests ORDER BY id DESC");
$runUsers2 = mysqli_query($con2,"SELECT * FROM users ORDER BY id DESC");
$numrows2 = mysqli_num_rows($run2);

    if( $numrows2 ) {
        while($row2 = mysqli_fetch_assoc($run2)){
            if($row2['status'] == "Approved"){
            //var_dump ($row2);

                $approved_id        = $row2['user_id'];
                $approved_firstname = $row2['firstname'];
                $approved_lastname  = $row2['lastname'];
                $approved_username  = $row2['username'];

    if ($approved_firstname == true) {
        echo "Name - ". $approved_firstname . " " . $approved_lastname . "

</br>" . 
                "Username - ". $approved_username . "</br></br>"

_POST由浏览器在提交表单时自动生成。 如果要通过帖子传递数据，则必须使用表单提交字段。 这些字段可以隐藏：

<input type=hidden name="lastname" value="{some_last_name}"/>
