Gravity Forms 向用户通知添加附件

Question

我正在使用 Gravity 表单中的以下代码将文件附加到用户的通知中：

add_filter( 'gform_notification_55', 'add_attachment_pdf', 10, 3 ); //target form id 2, change to your form id
function add_attachment_pdf( $notification, $form, $entry ) {
    //There is no concept of user notifications anymore, so we will need to target notifications based on other criteria,
    //such as name or subject
    if( $notification['name'] == 'User Notification' ) {
        //get upload root for WordPress
        $upload = wp_upload_dir();
        $upload_path = $upload['basedir'];

        //add file, use full path , example -- $attachment = "C:\xampp\htdocs\wpdev\wp-content\uploads\test.txt"
        $attachment = $upload_path . '/2020-RSPA-POS-Channel-KPI-Study-Update-Post-COVID.pdf';

        GFCommon::log_debug( __METHOD__ . '(): file to be attached: ' . $attachment );


    }
    //return altered notification object
    return $notification;
}

除了向表单 55 添加附件（如示例所示）之外，我还需要向不同的表单添加不同的附件。我已经更改了表单 ID 以反映这一点，并且 copied/pasted 代码第二次进入函数文件，但是网站在这样做时中断了。上面的工作按预期进行，就其本身而言。如何多次使用过滤器？

Answer 1

绝对最简单的方法（但不是最漂亮的）是复制所有内容并更改函数名称。这是一个示例，我在两个实例中更新函数名称以匹配表单 ID：

add_filter( 'gform_notification_55', 'add_attachment_pdf_55', 10, 3 );
function add_attachment_pdf_55( $notification, $form, $entry ) {
    ...
}

add_filter( 'gform_notification_56', 'add_attachment_pdf_56', 10, 3 );
function add_attachment_pdf_56( $notification, $form, $entry ) {
    ...
}
