贝宝按钮添加到购物车

Question

I'm trying to do an add to shooping cart button. But what happens now when I use the button is this: http://imgur.com/ldEEOK3

I want the button when I click on it, it adds the product to the cart, and stays in the same page.

<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>

And I will post the code for the show cart button, but I guess it has no problems since it is working fine:

<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!"> <img alt="" border="0" src="https://www.paypalobjects.com/pt_PT/i/scr/pixel.gif" width="1" height="1"> </form>

Answer 1

You may want to change some of the variables in the Add-to-cart button:

<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']; ?>">

<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>

Answer 2

The code you created is for "cart upload" function. It is usually used when some shopping cart feature has been embedded in your site and to pass the contents of shopping carts to PayPal for checkout and payment processing.
