Figuring out what info a form sends to webpage

Hi,

im a webdevelopment noob and am not really developing a website or anything but am trying to write a program that sends info (like traveldate etc) to travelsites and evaluates the prices the sites show in return.

Now i started with this site:
[url]www.skyscanner.de[/url], whos source code tells me the used form uses a “post” method to send the entered data to the next site.

[code=html]<form action=”/r/Search/” class=”clearfix” id=”search-controls-form” [B]method=”post”[/B]> <div class=”row”>
<div class=”two-col-layout” id=”departure”>
<label for=”departure-input”>Von</label>
<input name=”departure-input” id=”departure-input” tabindex=”1″ type=”text” list=”departure-list” autocomplete=”off” placeholder=”Land, Stadt oder Flughafen eingeben”
autocorrect=”off” autocapitalize=”off” spellcheck=”false”>
<span id=”departure-input-helper” class=”input-helper”></span>
</div>
<span id=”controls-swap” title=”Klicken Sie hier, um den Abreise- und Ankunftsort zu tauschen.”>
<span class=”hidden”>Klicken Sie hier, um den Abreise- und Ankunftsort zu tauschen.</span>
</span>
<div class=”two-col-layout” id=”destination”>

</div>
</div>
</form>[/code]

I tried using fiddler 2, firefoxes own network analysis tools and firebug to find out what info the post-command actually sends but i only see “get” requests once i hit the “submit” button.
How is this possible? and how can i find out what infos to send?

Thanks for any help ?

Also in #HTML _↴
