是否在状态更改时发送电子邮件通知？

Question

我如何才能使作业状态更改为“已取消”时，它会在提交后向我发送电子邮件通知我更改？

<form action='phplib/job_update.php' method='post' id='new_job'>
       <label for='status'>Job Status</label>
        <select name='status' id='status'>
            <?php
            $sql = "SELECT * FROM status";
            $result = mysqli_query($dbc3, $sql);
            while($row = mysqli_fetch_assoc($result)){
                echo "<option value='" . $row['id'] . "'";
                if($row['id'] == $data['status']) echo "selected='selected'";
                echo ">" . ucwords($row['name']) . "</option>";
            }
            ?>
        </select>
</form>

用PHP发送电子邮件有很多方法，但我将向您展示最简单的方法(假设您没有使用任何库或框架)。修改phplib/job_update.php脚本。在写入数据库之后(查找另一个mysqli_query(...)行)，添加以下代码：

$cancelledCode = // Easiest way to find this is to view source in the HTML
if ($cancelledCode == $_POST['status']) {
    $to = 'you@example.com';
    $subject = 'Cancelled Job';
    $message = 'Yo, a job has been cancelled. ...';
    if (!mail($to, $subject, $message)) {
        // Error sending mail
    }
}
