我正在使用一个 Photocrati WordPress 主题，它只有一个重定向到 PayPal 的结帐过程。我创建了一个新按钮，但我需要它来调用不同的操作，将购物车的内容发送到特定的电子邮件并将用户重定向到感谢页面，而无需支付网关，例如 PayPal。即使我成功创建了按钮，我也不知道如何完成这项工作，仅此而已。这似乎很简单，因为所有的价值都在那里，任何帮助或指导将不胜感激。Photocrati Themes 将 jQuery 和 php 组合用于购物车。购物车页面是一个 WordPress 模板页面文件，但这里是 sendcart.php（从模板页面文件调用的操作文件）：
define('ABSPATH', dirname(dirname(dirname(dirname(__FILE__)))).'/');
include_once(ABSPATH.'wp-config.php');
include_once(ABSPATH.'wp-load.php');
include_once(ABSPATH.'wp-includes/wp-db.php');
global $wpdb;
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);
// assign posted variables to local variables
$firstName = $_POST['first_name'];
$lastName = $_POST['last_name'];
$email = $_POST['payer_email'];
if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
$admin_info = get_userdata(1);
$admineaddr = get_option('admin_email');
if (isset($admin_info->user_email) && $admin_info->user_email != null)
{
$admineaddr = $admin_info->user_email;
}
// Send thank you email/receipt
$p_date = date("M d, Y");
$subject = "Thank you for your purchase!";
$message = "Thank you for your purchase! A notification will be sent to you by PayPal with the transaction details.";
$headers = "From: ".$admineaddr."\r\n";
$headers .= "Return-Path: ".$admineaddr."\r\n";
mail($email, $subject, $message, $headers);
$subject2 = "New Sale";
$message2 = "A new sale has been made:
Name: ".$firstName." ".$lastName."
Email: ".$email."";
$headers2 = "From: ".$admineaddr."\r\n";
$headers2 .= "Return-Path: ".$admineaddr."\r\n";
mail($admineaddr, $subject2, $message2, $headers2);
/* IMPORTANT! This code empties the entire cart! */
unset($_SESSION['cart']);
unset($_SESSION['cart_qty']);
?>
请帮忙！！谢谢。
