I know some others out there wanted to get rid of the subcategories, but there didn't seem to be anyone able to tell us how to do it. Now hopefully, this will help you:
In the includes>boxes>categories.php file at around line 93 (if you haven't changed anything, anyway) you should see the following lines:
CODE
//------------------------
if (tep_not_null($cPath)) {
$new_path = '';
reset($cPath_array);
while (list($key, $value) = each($cPath_array)) {
unset($parent_id);
unset($first_id);
$categories_query = tep_db_query("select c.categories_id, cd.categories_name, c.parent_id from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd where c.parent_id = '" . (int)$value . "' and c.categories_id = cd.categories_id and cd.language_id='" . (int)$languages_id ."' order by sort_order, cd.categories_name");
if (tep_db_num_rows($categories_query)) {
$new_path .= $value;
if (tep_not_null($cPath)) {
$new_path = '';
reset($cPath_array);
while (list($key, $value) = each($cPath_array)) {
unset($parent_id);
unset($first_id);
$categories_query = tep_db_query("select c.categories_id, cd.categories_name, c.parent_id from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd where c.parent_id = '" . (int)$value . "' and c.categories_id = cd.categories_id and cd.language_id='" . (int)$languages_id ."' order by sort_order, cd.categories_name");
if (tep_db_num_rows($categories_query)) {
$new_path .= $value;
and so on.
Change the //----------------------
to
/*----------This section prints the subcategories. Comment out to keep them hidden------------------
Now, go down to
CODE
}
tep_show_category($first_element);
$info_box_contents = array();
$info_box_contents[] = array('text' => $categories_string);
new infoBox($info_box_contents);
tep_show_category($first_element);
$info_box_contents = array();
$info_box_contents[] = array('text' => $categories_string);
new infoBox($info_box_contents);
and change to
CODE
}
*/
tep_show_category($first_element);
$info_box_contents = array();
$info_box_contents[] = array('text' => $categories_string);
new infoBox($info_box_contents);
*/
tep_show_category($first_element);
$info_box_contents = array();
$info_box_contents[] = array('text' => $categories_string);
new infoBox($info_box_contents);
Now just save and upload!
Hope this helps!
