categories list code
<?php
mysql_select_db($db_name, $conn); // Change for your database
$query_Recordset1 = "SELECT catid,catname,parentid FROM categories ";
$Recordset1 = mysql_query($query_Recordset1, $conn) or die(mysql_error()); // Change for your database
while ( $row = mysql_fetch_assoc($Recordset1) )
{
$menu_array[$row['catid']] = array('catname' => $row['catname'],'catid' => $row['catid'],'parentid' => $row['parentid']);
}
//recursive function that prints categories as a nested html unordered list
function generate_menu($parent)
{
$has_childs = false;
//this prevents printing 'ul' if we don't have subcategories for this category
global $menu_array;
//use global array variable instead of a local variable to lower stack memory requierment
foreach($menu_array as $key => $value)
{
if ($value['parentid'] == $parent)
{
//if this is the first child print '<ul>'
if ($has_childs === false)
{
//don't print '<ul>' multiple times
$has_childs = true;
//echo '<ul>';
echo '<ul id="categories">';
}
echo '<li><a href="categories?catid=' . $value['catid'] . '&parentid=' . $value['parentid'] . '&catname=' . $value['catname'] .'">' . $value['catname'] . '</a>';
echo '<input type="hidden" value="' . $value['catname'] . '" />';
generate_menu($key);
//call function again to generate nested list for subcategories belonging to this category
echo '</li>';
}
}
if ($has_childs === true) echo '</ul>';
}
//generate menu starting with parent categories (that have a 0 parent)
?>
