So, here’s the script I’ve used on both menus: <ul>
<?php
$flag = 0;
if (isset($_GET['c_id']))
{
$c_id = $_GET['c_id'];
include(“plus/db_con.php”);
$query = mysql_query (“SELECT c_id, c_name FROM categories WHERE c_depend=”.$c_id);
while ($row = mysql_fetch_array($query))
{
echo ‘<li><a href=”select-interests.php?int_id=’.$row['c_id'].’”>’.$row['c_name'].’</a></li>’;
}
mysql_close();
}
?>
</ul>And the second, where the sub-category is chosen and the coresponding items appear: <ul>
<?php
if (isset($_GET['int_id']))
{
include(“plus/db_con.php”);
$query = mysql_query (“SELECT int_name FROM interests WHERE c_id=”.$_GET['int_id']);
while ($row = mysql_fetch_array($query))
{
echo ‘<li><input type=”checkbox”><label for=”interestName”>’.$row['int_name'].’</label></li>’;
}
mysql_close();
}
?>
</ul>It functions as it is supposed to. The problem is (because of the _GET) when I choose a sub-category, all sub-categories disappear.So any ideas what would make it work?
