Question

Trouble getting to PayPal Buy Now Buttons to work on a single page in ASP.NET

Answer 1

A:

It's not your button that sends the value - it's the form it's in, and/or the code behind it. Could you:

Post the form code?
Post the code behind for this page?

Answer 2

+1 A:

The POST content of a button is every input in the FORM tag that surrounds the submit button. So to have each button submit a separate set of hidden fields you need to wrap the button and the desired hidden fields in a separate form:

<form ... >
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="ABC123">
<asp:ImageButton runat="server" id="PPImageButton1" PostBackUrl="https://www.paypal.com/cgi-bin/webscr" ImageUrl="https://www.paypal.com/en_US/i/btn/btn_buynow_SM.gif"/&gt;
</form>

<form ... >
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="ABC456">
<asp:ImageButton runat="server" id="PPImageButton1" PostBackUrl="https://www.paypal.com/cgi-bin/webscr" ImageUrl="https://www.paypal.com/en_US/i/btn/btn_buynow_SM.gif"/&gt;
</form>

Thanks for the reply. I basically screwed up in my explanation in that I didn't provide adequate detail. It is a SharePoint site and when I tried to add a second Form tag (to create the 1st button, I received an error stating nested forms were not supported in ASP.NET. So, I pulled the <form> out and the first button worked OK. Then when I added the 2nd button, I found the issue.

So is it working now with distinct forms for each product?

<form><input type="hidden" name="cmd" value="_s-xclick"><input type="hidden" name="hosted_button_id" value="ABC12">asp:ImageButton runat="server" id="PPImageButton1" PostBackUrl="https://www.paypal.com/cgi-bin/webscr" ImageUrl="https://www.paypal.com/en_US/i/btn/btn_buynow_SM.gif"/></form><form><input type="hidden" name="cmd" value="_s-xclick"><input type="hidden" name="hosted_button_id" value="ABC34"><asp:ImageButton runat="server" id="PPImageButton2" PostBackUrl="https://www.paypal.com/cgi-bin/webscr" ImageUrl="https://www.paypal.com/en_US/i/btn/btn_buynow_SM.gif"/></form>

My last comment is the current code which does not work. The first button appears to fucntion properly while the second button only refreshes the page.

Remus, you comments helped. I recieved some bad advice before posting here. I added the approprite switches to the <form> line and it appears to be working fine now. Thank you for setting me on the proper course.

Answer 3

A:

My noob solution for this was to cut each of the buy-it-now buttons and its associated fields out of the aspx page, and put each set in a separate html page.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
<html xmlns="http://www.w3.org/1999/xhtml"&gt;
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>first button</title>
</head>

<body>
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="paypal">
<input type="hidden" value="_s-xclick" name="cmd" /> <input type="hidden" value="???????" name="hosted_button_id" /> 
<table>
<tbody>
<tr>
<td><input type="hidden" value="Member name" name="on0" />Member name</td>

<td><input maxlength="60" size="30" name="os0" /></td></tr>
<tr>
<td><input type="hidden" value="Membership No. (if known)" name="on1" />Membership No. (if known)</td>
<td><input maxlength="60" size="6" name="os1" /></td></tr></tbody></table>
<input type="image" alt="PayPal - The safer, easier way to pay online." src="https://www.paypal.com/en_GB/i/btn/btn_cart_LG.gif"  name="submit" /> <img height="1" alt="" src="https://www.paypal.com/en_GB/i/scr/pixel.gif" width="1" border="0"/> </form>

</body>
</html>

In the place in the aspx page where you removed the button and other fields, insert an iframe which points to the html page like this:

<iframe width="600" height="" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="mybuttonpage1.htm"></iframe>
