Question

大家好我以下代码使用以下代码撰写报告：

$rp_options = array(
    'broring' => 'This is really boring',
    'difficult' => 'I don\'t understand this',
    'great' => 'Great stuff, need more'
);
$mail_report_to = 'me@domain.com');

function createReportPostForm() {
    global $rp_options, $post;
    $html = '
    <div id="formcont">
        <h3>Report this article</h3>
        <form id="myform">
            <p>
                <label for="name">What\'s wrong?</label>
                <select name="report-msg" id="report-msg">
                    <option val="">...</option>';
    foreach ($rp_options as $ok => $ov) {
        $html .= '
                    <option val="'.$ok.'">'.$ov.'</option>';
    }
    $html .= '
                </select>
                <input type="hidden" name="posturl" value="'.get_permalink().'" />
                <input type="hidden" name="action" value="ajax_action" />
                <input type="button" value="Submit" id="submit_button" />
            </p>
        </form>
    </div>
    <div id="output"></div>';
    return $html;
}
add_shortcode('rp-form', 'createReportPostForm');

我收到了表单，但它没有发送邮件，任何人都可以告诉我们在这段代码中错过了什么让它工作？感谢
