用Thinkphp給客戶開發網站的時候需要用到各大平臺付款功能，下面就免費分享給大家，此類是個成熟類，經過測試了（可以直接拿來使用，附帶使用方法，有需要的朋友請拿走。），
如果有需要安裝的演示請登陸“二當家的”檢視：http://www.erdangjiade.com/php/524.html目前包含了支付寶pc版、支付寶wap版、palpay、yeepay、unionpay、kuaiqian、財付通tenpay等，這幾個常用的支付平臺，支付方式均為即時到賬，不包含擔保支付。
支付配置ThinkPay\Application\Common\Conf\config.php

支付生成訂單 ThinkPay\ThinkPHP\Library\Think\Pay.class.php

function buildRequestForm(Pay\PayVo $vo) {
$this->payer->check();
//生成本地記錄資料
$check = M("Pay")->add(array(
'out_trade_no' => $vo->getOrderNo(),
'money' => $vo->getFee(),
'status' => 0,
'callback' => $vo->getCallback(),
'url' => $vo->getUrl(),
'param' => serialize($vo->getParam()),
'create_time' => time(),
'update_time' => time()
));

if ($check !== false) {
return $this->payer->buildRequestForm($vo);
} else {
E(M("Pay")->getDbError());
}
}

支付訂單表
