我有3個文本框輸入和一個貝寶形式的貝寶按鈕。PayPal IPN與PHP數據庫集成
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="text" name="a_name" id="name" placeholder="Artist name" />
<input type="email" name="email" id="name" placeholder="Email" />
<input type="text" name="url" id="email" placeholder="Url of your soundcloud track" />
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="NUYMPHY8BXZGN">
<input type="image" src="https://www.sandbox.paypal.com/nl_NL/NL/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal, de veilige en complete manier van online betalen.">

一旦一切都填好了，我們將被重定向到paypal。 我的PayPal IPN監聽器：

當我模擬IPN監聽器是工作，我得到插入值（空着，當然，因爲我們沒有在$ a_name $電子郵件等），它通過支付數據庫。 當我在網站上採取步驟時，這也會發生。 文本框中的值已丟失。我無法在我的payment.php（聽衆）中找回它們。
付款成功後，我應該怎麼做才能獲取值並將它們插入到數據庫中？我只是將空值插入到數據庫中。
解決!:
我所做的是我把$ _ POST值通過IPN監聽支付給我的電子郵件後。 我收到的是什麼這樣的：
：11： 「verify_sign」; S： 「AnNMT7nRteKS2auTkxdsRz9rRvvPAWwWAsbZm21nF1AGuSAtUwoLbcd」：56; S：11： 「PAYER_EMAIL」; S：20： 「[email protected]」 ; s：12：「option_name1」; s：8：「segujejg」; s：12：「option_name2」; s：16：「[email protected]」; s：12：「option_name3」; s：9： 「jsipegjie 」; S：6：「 txn_id」; S：17： 「61S77153EE2897129」; S：12：「payment_type
它成功接收的值，所以我不得不做的唯一的事情就是更換$_POST['a_name']與$_POST['option_name1']從Paypal退貨 現在有效
