<select size="1" name="period" onChange="getValue(this.form)">
<option selected value="all">Select a year</option>
<option value="2008">2008</option>
<option value="2007">2007</option>
</select>
</form>

<SCRIPT language=JavaScript>
function getValue(form) {

var val=form.period.options[form.period.options.selectedIndex].value;

}
</script>

<FORM name="form1" method="post" action="access.php?market=ca">
<SELECT name="supplier" onChange="document.getElementById('form1').submit();">

You could use a hidden variable in your second form to hold the period value from the first form:
<input type="hidden" name="period" value="<? print $_POST['period']; ?>" />

You would then access them in access.php using post variables.

$period = $_POST['period'];
$supplier = $_POST['supplier'];

Do you mind having the data traveling to access.php in GET only?
If not, the its as simple as creating another JS function which collects data from all the forms and then sends it off to access.php.

Use this JS function and then change
<SELECT name="supplier" onChange="document.getElementById('form1').submit();">
to
<SELECT name="supplier" onChange="sendValues();">

function sendValues() {
// get forms
var yearform = document.getElementById('test');
var supplierform = document.getElementById('form1');
 
// get selected values from forms
var year = yearform.period.options[yearform.period.options.selectedIndex].value;
var supplier = supplierform.options[supplierform.supplier.options.selectedIndex].value;
 
// create full URL
var address = 'access.php?market=ca&year='+year+'&supplier='+supplier;
 
// go there
window.locaction=address;
}

Open in new window
