How to build a custom URL from a HTML form?

Question

I have a HTML form like:

<form name="input" action="" method="post">
Username: <input type="text" name="user">
<input type="submit" value="Submit">
</form>

I need to build a URL when the submit link is clicked and send the user to it, using the username from the form in the correct position in the URL.

URL:

http://example.com/htmlchat/init.html?init_room=1&init_user=USERNAME_FROM_FORM_HERE

Can someone help (an example would be great)?

Why do you need the user value twice? You are already sending it as POST data. — Ke Vin

Don't use POST when you want the data to appear in the URL
Do put all the data you want in your URL in the form
Get the names of your fields right
Put the base URI in the action

such:

<form action="init.html">
    <input type="hidden" name="init_room" value="1">
    <label>
        Username: 
        <input name="init_user">
    </label>
    <input type="submit" value="Submit">
</form>

This is possible with either Javascript or a server side language such as PHP. With Javascript you want to update the action attribute.

You could use jQuery to do this.
