Sending Variable content, not Variable name

[Ian Hubling]

Here's what I'm trying to do:

I have a large number of pages that call a pop-up survey page. It is
important to know what page the survey is referring to - so I am
passing the name of the referring page through the URL.

The problem I'm having is that when the data on the survey page is
submitted through formmail, I can't seem to get the referring page's
name sent too - I keep getting the variable name itself, not the
contents of the variable.

So for instance, if the referring page is 123.htm, and I assign it to
variable "external_u rl", I get the name "external_u rl" sent through
formmail, not the contents of the variable.

HELP.

Here's the script I'm using to on the popup survey page (or at least
the part to parse out the referring page's name).

<Script LANGUAGE="javas cript">
external_url = window.location .search.substri ng(1);
</script>

Amongst my input fields for formmail I presume I would include:

<input type="hidden" name="subject" value="external _url">

But this doesn't work.

I haven't bothered to include the rest of the form code - but it is
working fine (ie I get the mail results back, its just that "subject"
comes back as "external_u rl" instead of the referring page's name.

Also, I know that "external_u rl" is working because I have a
document.write( external_url); in the document to ensure that the
variable is working and containing the correct info displayed on the
screen.

I figure this is a simple issue - but I can't figure it out. Thanks
in advance.

You can't just include variable names and expect javascript to interpret
them. Instead, you should have javascript write out the hidden input itself,
like this:

document.write( '<input type="hidden" name="subject" value="' + external_url
+ '">');

Your document will then contain a hdiden input with the correct value.

Thanks a million Matt - I had to play around with it - but I understood
what you were saying and managed to get it to work.

This will save a lot of work and coding in the long run. Again - thanks
for the help.
