简单整理一下PHP项目整合PayPal支付功能。
一、表单的构建:
form method="post" name="form" action="https://www.paypal.com/cgi-bin/webscr">input type="hidden" name="rm" value="2"/>input type="hidden" name="cmd" value="_xclick"/>input type="hidden" name="business" value="商家账号"/>input type="hidden" name="return" value="返回网址"/>input type="hidden" name="cancel_return" value="取消返回网址"/>input type="hidden" name="notify_url" value="用于接收PayPal发送的即时付款通知的URL,必须是有效的URL"/>input type="hidden" name="item_name" value="物品名称"/>input type="hidden" name="item_number" value="可用于跟踪购买或捐赠的传递变量,在付款完成时传回给您"/>input type="hidden" name="amount" value="物品的价格(购物车中所有物品的总价格"/>input type="hidden" name="currency_code" value="币种"/>form>
二、IPN验证部分
php class paypal { var$paypal_url='https://www.paypal.com/cgi-bin/webscr';//sandbox:https://www.sandbox.paypal.com/cgi-bin/webscrvar validate_ipn_response; function validate_ipn() {//验证IPN // parse the paypal URL$url_par=parse_url($this->paypal_url); // generate the post string from the _POST vars aswell as load the // _POST vars into an arry so we can play with them from the calling // script.$post_str = ''; foreach ($_POSTas$field=>$value) { $this->ipn_data["$field"] = $value; $post_str .= $field.'='.urlencode(stripslashes($value)).'&'; } $post_str.="cmd=_notify-validate"; // append ipn command // open the connection to paypal$fp = fsockopen($url_par[host],"80",$errnum,$errstr,30); if(!$fp) { // could not open the connection.returnfalse; } else { // Post the data back to paypalfputs($fp, "POST ".$url_par[path]." HTTP/1.1\r\n"); fputs($fp, "Host: ".$url_par[host]."\r\n"); fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n"); fputs($fp, "Content-length: ".strlen($post_str)."\r\n"); fputs($fp, "Connection: close\r\n\r\n"); fputs($fp, $post_str . "\r\n\r\n"); // loop through the response from the server and append to variablewhile(!feof($fp)) { $this->validate_ipn_response .= fgets($fp, 1024); } fclose($fp); // close connection} if (eregi("VERIFIED",$this->validate_ipn_response)) { returntrue; } else { returnfalse; } }
} ?>
