Loops and Paypal

[Schlo_50]

I am using a php shopping cart and would like to upload the entire contents of the cart to Paypal when the user is ready to checkout, including the individual item title/description and price.  I gather that the code I need to put on my checkout button is as follows:

 

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="upload" value="1">
<input type="hidden" name="business"      value="[email protected]">
<input type="hidden" name="item_name_1"      value="Item Name 1">   <input type="hidden" name="amount_1" value="1.00">
<input type="hidden" name="item_name_2"      value="Item Name 2">   <input type="hidden" name="amount_2" value="2.00">
<input type="submit" value="PayPal"></form>

 

However, I don't want to have to hard code the items and amounts, but would prefer to have a loop that runs for the item_name and amount incrementing the names (item_name_x and amount_x) and passing in the values using my variables ($item_title and $item_price).

 

If I have $item as the variable for individual items put in the shopping cart and $price as the variable for their prices does anybody have an snippet example of the loop I need to use along with the above paypal form please? Im just not sure how to loop and increment the form names together.

 

Help! Please?

 

Thanks in advance

I have the following loop for $item and $price but im not sure how to increment the form in the loop too?

Anyone got any idea?

 

foreach($bcartfile as $bKey => $Val){
$Data[$bKey] = explode("|", $Val);
$item = $Data[$bKey][0];
$pid = $Data[$bKey][1];
$price = $Data[$bKey][2];

    $bstr = $cartfile[$bKey];
    $bstr = explode('|', $str);
    $btotal += $bstr[2];
$fulltotal = $total+$pprice;

print "<tr>";
print "<td width=\"65%\" valign=\"top\">$item</td>";
print "<td width=\"35%\" valign=\"top\"><p align=\"right\">£$price</p></td>";
print "</tr>";
   }

 

Thanks

Can someone help me with the loop. I have had a go but need some help tweaking I think.

 

for($i = 1; $i < $item; $i++)
{
$z = "item_name_$i";
$y = "amount_$i";
}

print "<input type=\"hidden\" name=\"$z\" value=\"$item\">";
print "<input type=\"hidden\" name=\"$y\" value=\"$price\">";
