So, here's the deal. I have an html table that I want to populate. Specificaly the first row is the one that is filled with elements from a mysql database. To be exact, the table is a questionnaire about mobile phones. The first row is the header where the cellphone names are loaded from the database. There is also a select tag that has company names as options in it. I need to trigger an onChange event on the select tag to reload the page and refill the first row with the new names of mobiles from the company that is currently selected in the dropdown list. This is what my select almost looks like:

<select name="select" class="companies" onChange="reloadPageWithNewElements()">
<?php
    $sql = "SELECT cname FROM companies;";
$rs = mysql_query($sql);

while($row = mysql_fetch_array($rs)) {
    echo "<option value=\"".$row['cname']."\">".$row['cname']."</option>\n  ";
}
?>
</select>

So... is there a way to refresh this page with onChange and pass the selected value to the same page again and assign it in a new php variable so i can do the query i need to fill my table?

<?php
//$mobileCompanies = $_GET["selectedValue"];
$sql = "SELECT mname FROM ".$mobileCompanies.";";
$rs = mysql_query($sql);
while ($row = mysql_fetch_array($rs)) { 
    echo "<td><div class=\"q1\">".$row['mname']."</div></td>";
}

?>

something like this. (The reloadPageWithNewElements() and selectedValue are just an idea for now)
