Capturing a URL varible to a hidden field

Report · Jul 11, 2006

I am trying to pass 2 variables to a hidden fields on the next page. I then
want to use them in the code after then submit button is clicked.

I passed the 2 variables correctly though the URL and can capture one for
text on the page using:
<cfoutput>#URL.username#</cfoutput>

However, they are not working in the hidden fields. I have:

<cfoutput><input name="username" type="hidden" id="username"
value="#URL.username#" /> <input name="email" type="hidden" id="email"
value="#URL.email#" /></cfoutput>

Please help!

No obvious errors here, how is this "not working?" What incorrect
behavior|errors is happening?

On the IsDefined('Submit') I have:
<cfdirectory action="CREATE"
directory="E:\webs\mywebsite.com\#form.username#">

It keeps coming up with the literal #FORM.username# and creates a folder
called #form.username# verses the value that is captured in the hidden
field.

When I switch it to #URL.username# it seems to work.

What is the method parameter on the form page. If method is "get" then
you are sending the data as URL data not Form data which is method="post"

Agreed, but if I were to capture the URL variable into a hidden field,
wouldn't that make it a form variable to which I could use Form.?

if your form's method is GET, then you access the variables using URL._____
if your form's method is POST, then you access the variables using FORM._____

Oh, btw, the form is set to 'post' and the Form. was not working..

That is why I am confused.

Thanks

NOPE. What the values of a form are returned to the server as is solely
determined by the method parameter of the form.

Some code you can play with that might clear this up.

<cfsilent>

<cfparam name="url.Field" default="">
<cfparam name="form.Field" default="">

</cfsilent><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0

<body>
<h1>Form Methods</h1>

<h2>Get</h2>
<cfoutput>
<form method="Get">
<input type="text" name="Field" value="#form.field#" />
<input type="submit" />

<h2>Post</h2>
<form method="post">
<input type="text" name="Field" value="#url.Field#" />
<input type="submit" />
</form>

To follow up, when submitting the Get form, notice that the value is now
in the URL of the page.

I understand what you mean. Thanks.

Is it possible to reference a hidden variable after it has captured its
value from the URL?

If I have my hidden variable 'email' set to =#URL.email# can I reference
that in a <cfmail> after the form is submitted?
<cfoutput><input name="email" type="hidden" id="email" value="#URL.email#"
/></cfoutput>

Or is it better to just <cfset emailfrom = #URL.email#> then use that in the
<cfmail> area after the form is submitted?

I have the form set to:
<cfif IsDefined('submit')>
Create Dyanmic Folder
Copy File Into Folder
Send Email with attachent
INSERT form into database
UPDATE another database
Redirect to 'thank you page'
</cfif>
