我正在尝试为Gavity表单创建一个插件，我有一些在函数中工作的代码。php并使其正常工作，但我需要了解的是插件avity表单，即如何将代码集成到插件中，添加过滤器是否正常工作。
add_filter("gform_confirmation", "custom_confirmation", 10, 4);
function custom_confirmation($confirmation, $form, $lead, $ajax){
$gfe = $lead[\'id\'];
我使用这里的代码示例从gravity生成一个插件
https://github.com/rocketgenius/simpleaddonsimpleaddon。php源代码
