我有兩種方式可供用戶檢查:paypal和Php?
1.if user input (Amount field < 5(user credit):
do update database the remain amount in my database table.
2.if user input(Amount field) > 5(user credit):
Do paypal transaction with the submit form.
<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" id="payPalForm">
<input type="hidden" name="item_number" value="01 - General Payment to FreelanceSwitch.com">
<input name="item_name" type="hidden" id="item_name" size="45" value="Posting job">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="business" value="[email protected]">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="return" value="http://freelanceswitch.com/payment-complete/">
Paying Page:<input name="amount" type="text" id="amount" size="5">
<input type="submit" name="Submit" value="Pay">
</form>
任何人都可以告訴我怎麼做與貝寶提交表單的條件?
謝謝。
感謝@Donny天安,現在我已經試過:
編輯::
function compare_user_credit($paying_price, $user_credit){
$db = &JFactory::getDBO();
$user =& JFactory::getUser();
$user_id = $user->get('id');
if ($paying_price <= $user_credit) {
$remain_credit = $user_credit - $paying_price;
//DO UPDATE:enough credit
update_user_credit_after_paying($remain_credit,$user_id);
$action_after_paying = header("Location: index.php?xxxx=5");
}
# Case2 direct to paypal with the submit form.
else if ($paying_price > $user_credit){
//Need submit form to paypal.
$action_after_paying = header("Location: index.php=xxxx&paypal=".$_POST["amount"]);
}
return $action_after_paying;
}
$output = '<form method="POST" > ';
$output .='<h1>Credit:'.get_credit().'</h1>';
$output .= ' Paying Page <input type="text" name="amount" size=3 max_length=5 />';
$output .='<input type="submit" name="pay" value="pay" />' ;
echo $output;
if(isset($_POST["pay"])){
compare_user_credit($_POST["amount"], $user_credit);
}
我怎麼能這樣做與PayPal案例02

好的。它的工作原理,感謝你的班級。 – kn3l 2010-02-12 04:24:27
很高興聽到它的作品,順便說一句,這不是我的課,信用應該交給Micah;)這個類實際上只是包裝了您可以在Paypal開發人員的文檔中找到的關於PHP語言IPN的代碼示例。 Micah做得很好,把所有這些代碼放入一個可以輕鬆使用的類中。 – 2010-02-12 14:36:16
