You're right, i was just reading about it...
Well what i want to do next is build an url with this and other data that's ready and have a button to pass the data to my controller where i will use uri->element(id) and save the values to the several dbs that i have.
How can i proceed to do this?
what's the best way?

alert(x.selectedIndex + 1);[/quote]
Ok the value starts at 0 so no need to work around :)...
Now how can i pass this value and use it in my php code?[/quote]
I thought you'll just need the value inside a form, not passing it to PHP Code, hehe.. anyway, you might need Ajax for that to be able to pass the client side variable to the server side, I agree with the folks that help you out also here.

Yeah. Thanks.
I had to change this a bit so here's what's happening.
I now have 2 dropdown boxes. I click the first and the second shows the info based on the first one.
It's not working right because when i click the first dropdown the second gets populated with the last values in the database.
Here's what i'm saying:
Drop1
Drop2
Drop3
DB:
Id1 Item for Drop1
Id2 Item for Drop1
Id3 Item for Drop2
Id4 Item for Drop2
Id5 Item for Drop3
Id6 Item for Drop3
Whenever i select drop2 or 3 the next dropdown gets populated with Id5 and Id6. I've checked and it seems that my selected choice in the first dropdown isn't getting passed to the controller.
I did an Alert window and shows "Object object" so no value is getting there.
Can you help see what's wrong with my code?
Thanks.
View:
Code:
[removed]
function getState(){
$("#selectestate").bind("change",function(){
$("#selectcity").load("results/ajaxcity", {stat: $(this).val()} ); //This is where the problem is
alert({stat: $(this).val()});//Shows [Object object]
});
return false;
}
[removed]
........
$curstat=$this -> input -> post('state'); //current selected state in first dropdown
<tr>
<?php $js = 'id="selectstate" onChange="getState();"';?>
<td><h3> State: </h3></td>
<td id="selectestate"><?php echo form_dropdown('state', $stat, $curstat, $js);?></td>
</tr>
<tr>
<td><h3> City: </h3></td>
<td id="selectcity"><?php echo form_dropdown('city', $cit);?></td>
</tr>Controller
Code:
function ajaxcity()
{
$stat = $this->input->post('stat');
$data['searchcity'] = $this->Search->getCity($stat);
$this->load->view('city', $data);
}Ajax City View:
Code:
<?php foreach($searchcity as $row) :
$cit[$row->city] = &$row->city;
endforeach; ?>
<td><?php echo form_dropdown('city', $cit);?></td>
