Well I am suing Java script to capture the selected item and make it the value of my input box. But my problem is how to access this information from this point on. Can someone please tell me how I can use the selected item in my next SQL query?

Hello,
I am very new to php and mysql so please be patient with me. I don't even
know if I am using the right listing, but I hope someone can help me!
I need to create a <select> and the possible options are from my mysql database ( so far so good, I was able to find code to do that).
Now I need to use the user selected option to drive the options of me next
<select>. I need to know how to capture what user selected and how to pass
that around? I have used "onchange" attribute of the <select> to capture the
selected line but now how can I pass that to other php scripts? ( I need to
get the name of the country so that I can show a list of possible
state/province. I setting the value of the "newcountry" input to the
selected "country" but when I do echo $newcountry in quicksearch.php, its
blank!!)
Please help!!
Thanks so much
Here is what I have so far:
Quicksearch.php file has the following code
<br>
<table class='form'>
<tr>
<th>Steps 1-4</th>
</tr>
<tr><td>
<form name="fcountry" method="post">
<?php require("country_build.php");?>
<input type="text" name="newcountry" value="">
</form>
</td></tr>
</table>
<!-- quicksearch.php end -->
<script language="JavaScript">
<!--
function changeMenu()
{
document.fcountry.newcountry.value =
document.fcountry.country.options[document.fcountry.country.selectedInd ex].v
alue;
}
-->
</script>
Countrty_buil.php has the following
<?php
require_once("util.php");
echo "<SELECT name=\"country\" class=\"input\" onchange=\"changeMenu()\">";
//
// initialize or capture the country variable
$country = !isset($_REQUEST['country'])? "Select a country": $_REQUEST['country'];
$countrySQL = !isset($_REQUEST['country'])? "*": $_REQUEST['country'];
echo "<option value='$countrySQL' SELECTED>$country</option>";
$query = "SELECT country FROM ". TABLECOUNTRY . " ORDER BY country ASC";
// pconnect, select and query
if ($link_identifier = mysql_pconnect(DBSERVERHOST, DBUSERNAME, DBPASSWORD))
{
if ( mysql_select_db(DBNAME, $link_identifier)) {
// run the query
$queryResultHandle = mysql_query($query, $link_identifier) or die(
mysql_error() );
$ctrRows = mysql_num_rows($queryResultHandle); // row counter
// if data exists then $rows will be 1 or greater
if( $ctrRows == 0 ) {
echo"<option value='*'>No data found</option></select>";
}else{
// build the select list
while($row = mysql_fetch_object($queryResultHandle)) { //
grab a row
echo "<option value=\"$row->country\">$row->country</option>";
}
echo "</SELECT><br><br>";
}
}else{ // select
echo mysql_error();
}
}else{ //pconnect
echo mysql_error();
}
?>
