Custom Category List In Sidebar

    Hello and good day.
    I wish to ask for help with this code that I’ve found while searching around. Basically, I wanted the category widget to display only the child categories in the sidebar, but since I couldn’t find how to do so (by adding some filter codes in the functions.php), I’ve decided to try a custom category code that I’ve placed in the sibebar.php

    Here is the code that I am using.

    [ Moderator note: code fixed. Please wrap code in the backtick character or use the code button. ]

    <?php
global $post;
if (is_category( )) {
  $cat = get_query_var('cat');
  $parent = get_category ($cat);
  if ($parent->parent) {
    wp_list_categories ('child_of=' . $parent->parent);
    } else {
    wp_list_categories ('child_of=' . $cat);
  }
}
?>

    It actually works in the archive and category pages, but my problem is that it doesn’t show up when I’m on the post page.

    Any ideas?

    That is the big “if” in your code.

    Ah, yes. I have forgotten to post that I have already fixed this little issue of mine. Pardon me for being a newbie with WordPress though, but I did understand that is_category was for the category/archive pages, hence why it won’t work for the single post page.
    With that said, I researched about it and stumbled upon is_single. I then screwed around with the code and finally, I solved my simple problem which was annoyingly not so simple for a newbie like myself. 😛

    Here is my code for those who are curious~

    <?php
if (is_category( )) {
	$cat = get_query_var('cat');
	$parent = get_category ($cat);

	if ($parent->parent) {
		wp_list_categories ('child_of=' . $parent->parent);
	} else {
		wp_list_categories ('child_of=' . $cat);
	}
} else if(is_single( )) {
	$getcategory = get_the_category() ;
	$parentcatid = $getcategory[0]->category_parent;

	wp_list_categories ('child_of=' . $parentcatid);
}
?>
