Hi if anybody can hel with this one I will appreciate it.

I have the following code created by a cgi script:

<input type="image" src="http://images.paypal.com/images/x-click-but23.gif" border="0" name="submit" alt="Make payments with PayPal - it's fast, free and secure!">

      
      <input type="hidden" name="bn" value="BytesInteractive.A+ Download1.3">

<input type="hidden" name="business" value="latinflutes@comcast.net">

<input type="hidden" name="item_name" value="El Condor Pasa (The Fly Of The Condor )">

<input type="hidden" name="item_number" value="El Condor Pasa">

<input type="hidden" name="amount" value="1.30">

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

<input type="hidden" name="return" value="http://www.latinflutes.com/cgi-bin/aplusdownload/scripts/aplusdownload.cgi">

<input type="hidden" name="cancel_return" value="http://www.latinflutes.com/paypal/cancel.htm">

<input type="hidden" name="add" value="1">

     </form>

This creates a button for a single downloadable song. I want to use the same principal to create a form with twelve songs available for download where the customer can use checkboxes to select multiple songs to buy and download, and bypass the shipping module on the paypal shopping cart.

Thank you in advance

Kudos!

Hi guille_1 ,

You would need to modify the basic code in order to get all the information passed to the PayPal server.

You would use something like this example

Or this example below, You pick 10 checkboxes, you can adapt the code to your needs.:

Code:

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Sample Pack 10 flavors Choose 10</title>
<script type="text/javascript">
<!--
function Dollar (val) {  // force to valid dollar amount
var str,pos,rnd=0;
  if (val < .995) rnd = 1;  // for old Netscape browsers
  str = escape (val*1.0 + 0.005001 + rnd);  // float, round, escape
  pos = str.indexOf (".");
  if (pos > 0) str = str.substring (rnd, pos + 3);
  return str;
}

function ReadForm (obj1, tst) { // process radio and checkbox
var i,j,amt=0,des="",obj,pos,val,tok,tag,
  op1a="",op1b="",op2a="",op2b="",itmn="";
var ary = new Array ();
  if (obj1.baseamt) amt  = obj1.baseamt.value*1.0;  // base amount
  if (obj1.basedes) des  = obj1.basedes.value;  // base description
  if (obj1.baseon0) op1a = obj1.baseon0.value;  // base options
  if (obj1.baseos0) op1b = obj1.baseos0.value;
  if (obj1.baseon1) op2a = obj1.baseon1.value;
  if (obj1.baseos1) op2b = obj1.baseos1.value;
  if (obj1.baseitn) itmn = obj1.baseitn.value;
  for (i=0; i<obj1.length; i++) {  // run entire form
    obj = obj1.elements[i];        // a form element
    if (obj.type == "checkbox" ||  // checkboxes
        obj.type == "radio") {     //  and radios
      if (obj.checked) {           // did user check it—
        val = obj.value;           // the value of the selection
        ary = val.split (" ");          // break apart
        for (j=0; j<ary.length; j++) {  // look at all items
// first we do single character tokens...
          if (ary[j].length < 2) continue;
          tok = ary[j].substring (0,1); // first character
          val = ary[j].substring (1);   // get data
          if (tok == "@") amt = val * 1.0;
          if (tok == "+") amt = amt + val*1.0;
          if (tok == "%") amt = amt + (amt * val/100.0);
          if (tok == "#") {             // record item number
            if (obj1.item_number) obj1.item_number.value = val;
          ary[j] = "";                // zap this array element
          }
      }
        val = ary.join (" ");           // rebuild val with what's left

        tag = obj.id.substring (obj.id.length-2);  // get flag
        if      (tag == "1a") op1a = op1a + " " + val;
        else if (tag == "1b") op1b = op1b + " " + val;
        else if (tag == "2a") op2a = op2a + " " + val;
        else if (tag == "2b") op2b = op2b + " " + val;
        else if (tag == "3i") itmn = itmn + " " + val;
        else if (des.length == 0) des = val;
        else des = des + ", " + val;
      }
    }
  }
// Now summarize stuff we just processed, above
  if (op1a.length > 0) obj1.on0.value = op1a;
  if (op1b.length > 0) obj1.os0.value = op1b;
  if (op2a.length > 0) obj1.on1.value = op2a;
  if (op2b.length > 0) obj1.os1.value = op2b;
  if (itmn.length > 0) obj1.item_number.value = itmn;
  obj1.item_name.value = des;
  obj1.amount.value = Dollar (amt);
  if (obj1.tot) obj1.tot.value = "$" + Dollar (amt);
