Can I get the value using get_template_vars in php before the form got submit :

template.tpl
<select name ="box">
<option>option1</option>
<option>option2</option>
</select>
{include_php file="my.php"}
<input type=text name=myoutput value="{$result}">

my.php
<?php
$myinput = $this->get_template_vars("box");
//do mysql here to get data from database.
//and get the sql result - $sqlresult
$smarty->assign('result',$sqlresult);
?>

I tried that, but I can not the the value of box using get_template_vars before the forms got submit. Anyone can tell me whether I am right or wrong? How can I do that?

Can I do that in javascript after I got the selection value for 'box'? But how can I talked to the database in javascript?

Thanks!

Her, not sure what you're trying to do here..... but

You can't "talk to" the database in javascript. Javascript is a client side language. It is launched inside the browser.

PHP is a server language, therefore, you can only deal with what the user sends you (url, form data, ...). That mean that you can't know a form value before the user sends his form.

PHP and Javascript can't talk to each other (except if by "talk together" you consider javascript generation in PHP, or javascript url generation to "call" a PHP page)

Hope this helps...

Thanks a lot! It cleared up my mind.
