自定义捐款/付款前台模板目录为：

/gathering/show.html

其中show.html可以由后台自定义文件

一、付款界面（/gathering/show.html）代码：

{template "header.html"}
付款标题：{$title}

付款表单：
{$payform}

{template "footer.html"}

二、付款表单（config/pay/gathering.html）界面代码：

<form action="/index.php?s=member&c=pay" class="form-horizontal" method="post" name="myform" id="payform">
    {dr_form_hidden()}
    <input type="hidden" name="pay[url]" value="{$html.url}" />
