Question

I am just experimenting with some databases for my webshop.
And right now I try to add products through an admin pages to my database.
I have this in :

<?php
function test(){the code}
?>

and in body I have a form with this:

<form action="test()" method="post">
</form>

Is this possible to do with xHTML or not?
If not what would be the best way?

If you want to use PHP and a form to submit data just use this example:

<?php
if(isset($_POST['submit'])){
$myvar = $_POST['myvar'];
echo $myvar;
}
?>
<form action='' method='POST'>
<input type='text' name='myvar'>
<input type='submit' name='submit'>
</form>

Now if you want to use that data in a javascript function try.

<script type="text/javascript">
function myfunction(){
var MyData = document.getElementById('myvar').value;
}
</script>
<form action='' method='POST'>
    <input type='text' id='myvar'>
    <input type='submit' onClick='myfunction()' id='submit'>
    </form>
