Hi,
For some reasons I don't want to show some categories on the homepage (index.php/home.html). (It has nothing to do with user/category permissions)
I will explain:
I added an additional category field: cat_not_show
In functions.php I need help to tweak the function "get_categories" to make it not showing the category with cat_not_show = 1:
function get_categories($cat_id = 0) {
global $site_template, $site_db, $site_sess, $config, $lang;
global $cat_cache, $cat_parent_cache, $new_image_cache, $subcat_ids;
$cattable_width = ceil((intval($config['cat_table_width'])) / $config['cat_cells']);
if ((substr($config['cat_table_width'],-1)) == "%") {
$cattable_width .= "%";
}
if (!isset($cat_parent_cache[$cat_id])) {
return "";
}
$visible_cat_cache = array();
foreach ($cat_parent_cache[$cat_id] as $key => $val) {
if (check_permission("auth_viewcat", $val)) {
$visible_cat_cache[$key] = $val;
}
}
if (empty($visible_cat_cache)) {
return "";
}
$total = sizeof($visible_cat_cache);
$table_columns = (intval($config['cat_cells'])) ? intval($config['cat_cells']) : 2;
if ($total <= $table_columns) {
$table_rows = 1;
}
else {
$table_rows = $total / $table_columns;
if ($total >= $table_columns && !is_integer($table_rows)) {
$table_rows = intval($table_rows) + 1;
}
}
$categories = "\n<table width=\"".$config['cat_table_width']."\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\">\n<tr>\n<td valign=\"top\" width=\"".$cattable_width."\" class=\"catbgcolor\">\n";
$categories .= "<table border=\"0\" cellpadding=\"".$config['cat_table_cellpadding']."\" cellspacing=\"".$config['cat_table_cellspacing']."\">\n";
$count = 0;
$count2 = 0;
foreach ($visible_cat_cache as $key => $category_id) {
$categories .= "<tr>\n<td valign=\"top\">\n";
$is_new = (isset($new_image_cache[$category_id]) && $new_image_cache[$category_id] > 0) ? 1 : 0;
$num_images = (isset($cat_cache[$category_id]['num_images'])) ? $cat_cache[$category_id]['num_images'] : 0;
$subcat_ids = array();
get_subcat_ids($category_id, $category_id, $cat_parent_cache);
if (isset($subcat_ids[$category_id])) {
foreach ($subcat_ids[$category_id] as $val) {
if (isset($new_image_cache[$val]) && $new_image_cache[$val] > 0) {
$is_new = 1;
}
if (isset($cat_cache[$val]['num_images'])) {
$num_images += $cat_cache[$val]['num_images'];
}
}
}
if (defined("SHOW_RANDOM_IMAGE") && SHOW_RANDOM_IMAGE == 0 || defined("SHOW_RANDOM_CAT_IMAGE") && SHOW_RANDOM_CAT_IMAGE == 0) {
$random_cat_image_file = "";
}
else {
$random_cat_image_file = get_random_image($category_id, 0, 1);
}
$site_template->register_vars(array(
"cat_id" => $category_id,
"cat_name" => format_text($cat_cache[$category_id]['cat_name'], 2),
"cat_description" => format_text($cat_cache[$category_id]['cat_description'], 1),
"cat_hits" => $cat_cache[$category_id]['cat_hits'],
"cat_is_new" => $is_new,
"lang_new" => $lang['new'],
"sub_cats" => get_subcategories($category_id),
"cat_url" => $site_sess->url(ROOT_PATH."categories.php?".URL_CAT_ID."=".$category_id),
"random_cat_image_file" => $random_cat_image_file,
"num_images" => $num_images
));
$categories .= $site_template->parse_template("category_bit");
$count++;
$count2++;
$categories .= "</td>\n</tr>\n";
if ($count == $table_rows && $count2 < sizeof($visible_cat_cache)) {
$categories .= "</table></td>\n";
$categories .= "<td valign=\"top\" width=\"".$cattable_width."\" class=\"catbgcolor\">\n";
$categories .= "<table border=\"0\" cellpadding=\"".$config['cat_table_cellpadding']."\" cellspacing=\"".$config['cat_table_cellspacing']."\">\n";
$total = $total - $count2;
$table_columns = $table_columns - 1;
/*if ($total <= $table_columns && $table_columns > 1) {
$table_rows = 1;
}
else {
$table_rows = $total / $table_columns;
if ($total >= $table_columns && !is_integer($table_rows)) {
$table_rows = intval($table_rows) + 1;
}
}*/
$count = 0;
}
}
$categories .= "</table>\n</td>\n</tr>\n</table>\n";
return $categories;
}
Any help will be aprrecaited,
Thanks in advance,
Cruxy
