Passing Dynamic Variable In A Hidden Form

[Chizzy66]

Hello:

I am trying to pass a hidden variable from a form on my web application to the
PayPal site for payment processing. I can get my code to work on my development
machine (CF MX 7); however, I am getting the following error message when I try
to run it on the hosting server (CF MX 6).

I have tried to use an html form with <input> tags instead of the <cfinput>
tags; however, I run into a problem when I try to pass a string that has been
dynamically generated (#custom#) in the code example below. Instead of passing
my string, it is literally passing the value of #custom# as the variable.

Here is the code below with non problematic parts removed in the interest of
space:

<!--- Generate A Custom Variable To PASS To PayPal --->
<cfset custom = #CreateUUID()#>

<!--- Create the hidden form to pass PayPal button information --->
<cfform action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
<cfinput type="hidden" name="cmd" value="_xclick">
<cfinput type="hidden" name="business" value="businessname@mycompany.com">
<cfinput type="hidden" name="item_name" value="Thing For Sale">
<cfinput type="hidden" name="item_number" value="1">
<cfinput type="hidden" name="amount" value="10.00">
<cfinput type="hidden" name="no_shipping" value="2">
<cfinput type="hidden" name="no_note" value="1">
<cfinput type="hidden" name="currency_code" value="CAD">
<cfinput type="hidden" name="lc" value="CA">
<cfinput type="hidden" name="custom" value="#custom#">
<cfinput type="image"
src="https://www.paypal.com/en_US/i/btn/x-click-butcc.gif" border="0"
name="submit_single" alt="Click here to process your credit card payment via a
secure web site.">
<cfinput type="submit" name="Submit" value="Process My Credit Card Payment">
</cfform>

Thank you for any advice that you can offer me with this problem. Moving the
site to a CF7 server at this time is not an option for me.

Hi Paul,

In CF6, CFINPUT only support the following types:
RADIO,CHECKBOX,PASSWORD,TEXT. Use HTML INPUT tag. You may leave the CFFORM.

Hello Laksma:

Thank you for the fast response. I have tried using the HTML <input> tag as
follows:

<input type="hidden" name="custom" value="#custom#">

<cfinput type="hidden" name="custom" value="<cfoutput>#custom#</cfoutput>">

However, both of those statements pass the string as #custom# instead of the
string that I assigned to the variable called custom using the following
statement:

<cfset custom = #CreateUUID()#>

The statement above creates a string in the form of:
976B81AD-B0D0-6834-297A02473995683F
That I need to pass to PayPal. Thanks again for any advice or assistance that
you can provide.

Try
<cfoutput>
<input type="hidden" name="custom" value="#custom#">
</cfoutput>

I tried the code using CFMX6.1 and it works fine. Also try what Ken suggested. Put CFOUTPUT.
