create 2 drop down lists from text file

[VenusJ]

hello all,

I need to find out how exactly can I interact these 2 variables in 2 drop down lists.

Here is the problem...
I have something like that in statesfiles.php:

$states = "Califonia, Taxes, Washigton";

$Califonia = "city1,city2,city3"; 
$Taxes = "city1,city2,city3";
//....and so on.

The form part is like this:

print "<SELECT NAME=\"sellerstates\"> ";
print "<option value=\"\">---Please select your states---";
//deal with states
$sellercityarray = explode(",", $sellerstateslist);
  while (list($IndexValue, $sellerstatesselect) = each($sellerstatesarray))
{
 echo "<option value=\"$sellerstatesselect\">$sellerstatesselect";
 }
print "</select>";

The States drop down list prints out perfectly right now for the name of the States, but what i want is when I select Califonia from the State drop down list, it will automatically give me the City Names on the second drop down list. I know javascript might be needed for this to work, but can someone lead me to the right direction?

Thanks for your help

Here's your javascript for the States menu:

<select name="State" onchange="window.location=('{$php_self}?State=' + this.options[this.selectedIndex].value)">

And you display a different cities menu depending on the value of $_GET['State'].

P.S. I think the states are named California, Texas, and Washington. 🙂
