It depends on which method you use,
GET or POST. In both cases, you'll have to track down the form elements and build up a data string based of
variables and their corresponding, optional
values.
Using the GET method is simple:
var %data = [color:blue]var[/color]=[color:brown]value[/color]&[color:blue]another_var[/color]=[color:brown]value[/color]
sockwrite -n $sockname GET /path/file.cgi? $+ %data HTTP/1.1
sockwrite -n $sockname Host: <host>
sockwrite -n $sockname Connection: close
sockwrite -n $sockname
However the POST method is a little bit complicated. You'll have to specify two additional header lines, and the form data is moved to the end of the request, below the ending CRLF:
var %data = [color:blue]var[/color]=[color:brown]value[/color]&[color:blue]another_var[/color]=[color:brown]value[/color]
sockwrite -n $sockname POST /path/file.cgi HTTP/1.1
sockwrite -n $sockname Host: <host>
sockwrite -n $sockname Connection: close
sockwrite -n $sockname Content-Type: application/x-www-form-urlencoded
sockwrite -n $sockname Content-Length: $len(%data)
sockwrite -n $sockname
sockwrite -n $sockname %data
For example, let's take the
Search page of our lovely board.
First, we track down the form elements.
<form method="[color:red]post[/color]"
action="https://forums.mirc.com/dosearch.php">
...
<input type="hidden" name="[color:blue]Cat[/color]" value="" />

class="buttons" />
</form>
Yes I do realize that this is a somewhat tiring work, thus where the form uses the GET request, you can first open it on your browser, and learn the variable names from what it displays in the address bar.
If the POST method is used, the browser won't tell what it sends, but you can however use a packet capturing program such as
Ethereal to capture the outgoing HTTP request and learn from it.
For this example, I decided to search for the word "remote" over the "scripts and popups" board one week back. And here's how the script will look like:
alias form sockopen form forums.mirc.com 80
On *:sockopen:form:{
var %data = [color:blue]Cat[/color]=&[color:blue]Forum[/color]=[color:brown]scriptsandpopups[/color]&[color:blue]Word[/color]s=[color:brown]remote[/color] $+ $&
&[color:blue]Match[/color]=[color:brown]entire phrase[/color]&[color:blue]Old[/color]=[color:brown]1week[/color]&[color:blue]Limit[/color]=[color:brown]25[/color]&[color:blue]buttsubmit[/color]=[color:brown]submit[/color]
sockwrite -n form POST /dosearch.php HTTP/1.1
sockwrite -n form Host: forums.mirc.com
sockwrite -n form Connection: close
sockwrite -n form Content-Type: application/x-www-form-urlencoded
sockwrite -n form Content-Length: $len(%data)
sockwrite -n form
sockwrite form %data
}
On *:sockread:form:{
var %s
sockread %s
while $sockbr {
echo -s -> %s
sockread %s
}
}Paste this into the remote and type /form to begin.
Note: variable names are case sensitive; make sure they are typed correctly.
I hope it helped. If you need help on sending HTTP requests, check
this page. Most likely I won't be here until Saturday night, but you're welcome to ask furthermore and hopefully someone else will be able to answer.
