Hi to all,
I have two listboxes, one is state and another is city. As user changes the state, the value of city listbox w.r.t state shuld changed. I do it with using, but I want to do it when user make a selction from state listbox.
//two-list.php
<?php
$con=mysql_connect("localhost","root","");
$db=mysql_select_db('admin');
$state=$_POST['state'];
$city=$_POST['city'];
$submit=$_POST['submit'];
if(!empty($submit))
{
echo "State selected by you :".$state;
echo "<br/>";
echo "State selected by you :".$city;
echo "<br/>";
echo "<br/>";
$insert=mysql_query("insert into state(state,city) values('$state','$city')");
}
?>
