PHP貝寶動態地傳遞多個項目

Question

我想添加多個產品進行處理在貝寶上。 訂單總結不顯示任何項目。我正在PayPal沙盒上試用它。

下面是完整的代碼：

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" id="paypal"> 

<input type="hidden" name="cmd" value="_xclick" /> 
<input type="hidden" name="upload" value="1"> 
<input type="hidden" name="cbt" value="Return to max shop" /> 
<input type="hidden" name="business" value="example@gmail.com"> 

<?php 
if(isset($_SESSION['products'])) 
{ 
    $obj=new project; 
    $i=1; 
    foreach($_SESSION['products'] as $product) 
    { 
     $sql=$obj->get_products($product['id']); 
     $row=mysql_fetch_array($sql); 
     ?> 
     <input type="hidden" name="item_number_<?php echo $i ?>" value="<?php echo $i ?>"> 
     <input type="hidden" name="item_name_<?php echo $i ?>" value="<?php echo $row['title'] ?>" /> 

     <input type="hidden" name="amount_<?php echo $i ?>" value="<?php echo $row['cost'] ?>"> 
     <input type="hidden" name="item_quantity_<?php echo $i ?>" value="<?php echo $product['qty'] ?>"> 

     <?php 
     $i++; 
    } 
} 
?> 


<input type="hidden" name="button_subtype" value="services" /> 
<input type="hidden" name="no_shipping" value="1" /> 
<input type="hidden" name="return" value="http://localhost/oops" /> 

<input type="hidden" name="currency_code" value="USD"/> 

<input type="hidden" id="custom" name="custom" value="invoice_id to track"/> 
<input type="hidden" class="btn btn-primary" style="width:100%" alt="PayPal - The safer, easier way to pay online!"/> 
<input type="image" src="http://www.paypalobjects.com/en_US/i/btn/x-click-but23.gif" border="0" name="submit" width="68" height="23" alt="Make payments with PayPal - it's fast, free and secure!"> 
</form> 

我也試着像下面的排列格式，但沒有收到任何結果;

<input type="hidden" name="item_number[<?php echo $i ?>]" value="<?php echo $i ?>"> 
<input type="hidden" name="item_name[<?php echo $i ?>]" value="<?php echo $row['title'] ?>" /> 
    <input type="hidden" name="amount[<?php echo $i ?>]" value="<?php echo $row['cost'] ?>"> 
    <input type="hidden" name="item_quantity[<?php echo $i ?>]" value="<?php echo $product['qty'] ?>">

上傳命令只適用於_cart而不是_xclick。

改變這一行到：

<input type="hidden" name="cmd" value="_cart" /> 

<form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post" id="paypal"> 

<input type="hidden" name="cmd" value="_cart" /> 
<input type="hidden" name="upload" value="1"> 
<input type="hidden" name="cbt" value="Return to max shop" /> 
<input type="hidden" name="business" value="XXX-facilitator@gmail.com"> 

<?php 
$_SESSION['products'] =2; 
$product =''; 
$pro =array("red","green"); 
if(isset($_SESSION['products'])) 
{ 
    // $obj=new project; 
    $i=1; 
    foreach($pro as $key) 
    { 
     //$sql=$obj->get_products($product['id']); 
     $row='row'; 
     ?> 
     <input type="hidden" name="item_number_<?php echo $i ?>" value="<?php echo $i ?>"> 
     <input type="hidden" name="item_name_<?php echo $i ?>" value="title" /> 

     <input type="hidden" name="amount_<?php echo $i ?>" value="10.00"> 
     <input type="hidden" name="item_quantity_<?php echo $i ?>" value="product"> 

     <?php 
     $i++; 
    } 
} 
?> 


<input type="hidden" name="button_subtype" value="services" /> 
<input type="hidden" name="no_shipping" value="1" /> 
<input type="hidden" name="return" value="http://localhost/oops" /> 

<input type="hidden" name="currency_code" value="USD"/> 

<input type="hidden" id="custom" name="custom" value="invoice_id to track"/> 
<input type="hidden" class="btn btn-primary" style="width:100%" alt="PayPal - The safer, easier way to pay online!"/> 
<input type="image" src="http://www.paypalobjects.com/en_US/i/btn/x-click-but23.gif" border="0" name="submit" width="68" height="23" alt="Make payments with PayPal - it's fast, free and secure!">
