php - Paypal 按钮添加到购物车

Question

我正在尝试添加到购物车按钮。但是现在当我使用按钮时会发生什么:http://imgur.com/ldEEOK3

我想要按钮，当我点击它时，它将产品添加到购物车，并停留在同一页面。

<tr class="record">

    <td><?php echo $row['ref']; ?></td>
    <td><?php echo $row['nome']; ?></td>
    <td><?php echo $row['preco']; ?></td>
    <td><form method="post" action="https://www.paypal.com/cgi-bin/webscr" target="paypal">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business" value="paypalID"> //not gonna show it :p

<input type="hidden" name="item_name_1" value="<?php echo $row['nome']; ?>">
<input type="hidden" name="quantity_1" value="1">
<input type="hidden" name="amount_1" value="<?php echo $row['preco']; ?>">

<input type="image" src="https://www.paypalobjects.com/pt_PT/PT/i/btn/btn_cart_SM.gif" border="0" name="submit" alt="PayPal - A forma mais fácil e segura de efetuar pagamentos online!">
<img alt="" border="0" src="https://www.paypalobjects.com/pt_PT/i/scr/pixel.gif" width="1" height="1">
</form>
</tr>

我将发布显示购物车按钮的代码，但我想它没有问题，因为它工作正常:

<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post" >
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="encrypted" value="erased the big encrypt code">
<input type="image" src="https://www.paypalobjects.com/pt_PT/i/btn/btn_viewcart_SM.gif" border="0" name="submit" alt="PayPal - A forma mais fácil e segura de efetuar pagamentos online!">

</form>

您可能想要更改“添加到购物车”按钮中的一些变量:

<form method="post" action="https://www.paypal.com/cgi-bin/webscr" target="paypal">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="add" value="1">
<input type="hidden" name="business" value="paypalID"> //not gonna show it :p

<input type="hidden" name="item_name" value="<?php echo $row['nome']; ?>">
<input type="hidden" name="quantity" value="1">
<input type="hidden" name="amount" value="<?php echo $row['preco']; ?>">
