How can I get this tabbed search form to work?

One search box, many actions

[ifyourmotheronlyknew]

But I'm having trouble wrapping my head around it. How would I go about adding different form actions while keeping them hidden, so that only one search form is showing?

For instance: Let's say I wanted to have the search form on WEB to search Google (I can set up the form) but how do I make it so the action changes when you click on IMAGES (let's say I wanted it to search Google Images - again, I can set up the form for that, but how do I make it so the action changes when clicking the tab?)

Thanks! :)

2 ways i would do it, one is to dynamicly edit the form action,

function updateAction(q,f){
 var form = document.getElementById(f);
 form.action = q;
}

the your form would look like this,

<form method='post' action='search.php' name='search' id='form'>
Query: <input type='text' name='q' /> <input type='submit' value='search..' />
<br />
<a href='#' onClick="updateAction('imagesearch.php','form');">Image Search</a>

and you could list as many actions as you wanted, just editing the action with updateAction, only you cant append form actions with a REQUEST so you would need diffrent pages for each search type, which i think is messy, so a better way would to add a hidden value called searchtype that just updates on click and then use a php to search depending on what came in on 'searchtype'...

function updateValue(v,i){
 var field = document.getElementById(i);
 field.value = v;
}

your HTML would then look like this,

<form method='post' action='search.php' name='search' id='form'>
Query: <input type='text' name='q' /> <input type='submit' value='search..' />
<input type='hidden' name='searchtype' id='searchtype' value='search' />
<br />
<a href='#' onClick="updateValue('image','searchtype');">Image Search</a>

hope that makes sense, the best way i think is the second...
