Question

我有以下功能：

add_action('frm_after_create_entry', 'dmdSendTestKeyZGS', 30, 2);
function dmdSendTestKeyZGS($entry_id, $form_id){
    global $wpdb;
    if($form_id == 13){
        global $wpdb;
        $myrow = $wpdb->get_row( "SELECT * FROM mi_zgskeys WHERE used = 0", ARRAY_A);
        $id = $myrow['id'];
        $key = $myrow['key']; //KEY IS STORED
        $wpdb->query("UPDATE mi_zgskeys SET used = 1 WHERE id = $id");
        $body = get_email_body_wpse_96357($key); 
        $headers = array('Content-Type: text/html; charset=UTF-8');
        if(isset($_POST['item_meta'][96]))
            wp_mail($_POST['item_meta'][96], 'test', $body, $headers);
    }
}

function get_email_body_wpse_96357($key) {
    $body = "<!DOCTYPE html>
<html>
<head>
    <meta charset=\"UTF-8\">
    <title>Ihr Test-Lizenzschlüssel</title>
</head>
<body>
    <div>
        <div>
            <p><a><?php echo $key; ?></p> //$key EMPTY???
        </div>
    </div>
</body>
</html>";
    return $body;
}

有人可以告诉我为什么模板中的$key为空吗？

如果我发送电子邮件，则该字段未填写且不确定原因。

只需将 <?php echo $key; ?> 替换为 $key 。 http://php.net/manual/en/language.types.string.php#language.types.string.parsing

将var传递给wp_mail模板函数
