[Libcgi-general] Fetching all parameters

[Bill M. <mo...@ha...>]

I need to covert all the form parameters into a new query string -- but
I do not know the names of the form variables.  

My quick look at the API doesn't show a method for this -- seems like I
need to specify the name.  What does cgi_process_form() return?  Would
that provide me with that info?

I need a simple click-through script -- where GET or POST parameters are
read and built into a new query string and then a redirect is sent.  One
of the passed in parameters is the URL of the redirect location.

For example, I might have a form:

<FORM method=GET action="http://localhost/redirect.cgi">
        <input type="hidden" name="__redirect" value="http://google.com">
        <INPUT TYPE=hidden name=num value=50>
        <INPUT TYPE=hidden name=hl value=en>
        <INPUT TYPE=hidden name=safe value=off>
        <INPUT TYPE="text" NAME="q" VALUE="" SIZE="30" MAXLENGTH="256">
        <INPUT TYPE="submit" VALUE="Go">
</FORM>

That would generate a redirect with a Location: of:

   http://google.com?num=50&hl=en&save=off&q=query

The point, of course, is to log the click-throughs on external links.


By the way -- there seems to be a number of C cgi libraries around.
Anyone know how they compare?

Thanks
