<form method="POST" action="/index?key=1">
<input type="text" name="another_key" value="2" />
</form>
When I submit such a form and trying to fetch the GET parameter with CGI->new->param('key'),
it doesn’t work..
Can CGI work when both GET and POST parameters exist?
For a POST request, CGI’s param method will only get post parameters, but there is an alternate url_param method that will provide the “GET” parameters from the url.
This can be very helpful for file uploads; if the post request is too large, it will be entirely discarded, but the url parameters can tell you what kind of upload it was so you can show the user an error message in the correct context.
