Forms/ submit buttons that direct to URL based on user input

Question

I have a form on a webpage:

<?php echo form_open('/search/processing'); ?>

<input type="text" name="query" size="50" />

    <input type="submit" name="1" value="1" /></br>
    <input type="submit" name="2" value="2" /></br>
    <input type="submit" name="3" value="3" /></br>

</form>

It goes to this controller function:

public function processing()
{
// redirects here based on user input and what submit button was pressed
}

I'm wondering is it possible to get rid of this function and simply redirect straight from the form based on what the user has entered?

your answer lies in javascript, this may help you: http://stackoverflow.com/questions/503093/how-can-i-make-a-redirect-page-in-jquery-javascript — Peeyush Kushwaha, Jul 23 '12 at 15:27
Yes it is possible, Can you please elaborate it more, probably with some example? — FatalError, Jul 23 '12 at 15:29
Havent had time to try it, but if you need it in javascript, cant you use the onvalidate to alter the action url? As i say, i havent tried it but that was what sprang to mind. If you havent sorted it, ill try that out later this afternoon. — Adrian Brown, Jul 23 '12 at 15:31
You can't override the controller's method but using `Javascript` you can achieve this. — The Alpha, Jul 23 '12 at 15:40

<script>
window.addEventListener('load', function(){
    document.getElementById('formid').addEventListener('submit', function(){
        for(var i = 0; i < this.length; i++)
            if(this[i].type == 'submit' &&
               this[i].value == 1) window.location.href = 'foo.com';
            else if( ... )
               ....
            else if( ... )
               ....
    }, false);
}, false);

If you want to use pure PHP, then:

if(isset($_POST['query']))
{
  switch($_POST['query'])
  {
    case 'hello': header('location: http://www.google.com'); break;
    case 'stack': header('location: http://www.ask.com'); break;
    case 'overflow': header('location: http://www.yahoo.com'); break;
  }
}

OP is using `CodeIgniter framework` and don't want to use the controller to be invoked, this answer is not helpful in this case. – The Alpha Jul 23 '12 at 15:32
Other than using a tag, OP did not state this. – Ben Poulson Jul 23 '12 at 15:44

Yes, this can be achieved in the following: Where the comments are, include redirect code, or a function call.

if (isset($_POST['query']) {
  $value = $_POST['query'];
  if ($value == 1) {
    //do something
  }
  if ($value == 2) {
    //do something
  }
}

Here is a plain javascript version of changing the form action, it may not be exactly what you want as you have 3 seperate buttons, but it maybe useful.

<script type="text/javascript">
function test()
 {
     if ( document.forms.form.test1.checked )
     {
         document.forms.form.action = "http://google.com";
     }

     return true;
 }
</script>
<form name="form" action="a.html" onsubmit="return test()">
    <input type="checkbox" id="test1" name="test1" />
    <input type="submit" value="submit" />
</form>

Basically if you have the button checked it goes to google.com - else a.html
