Question

I'm having trouble with a widget that displays the most recent categories.

Code: https://ghostbin.com/paste/6cwa5 https://ghostbin.com/paste/rtnqa

It is displaying fine on the main page but when I go to a post page, it only shows that pages' categories.

Also, I have to force the widget to close with the aside tag.

What am I doing wrong? Should I not be using the wp_get_recent_posts function?

Why doesn't array_key_exists('after_widget', $args) return true using twelvefifteen theme?

Answer 1

Why do you use wp_get_recents_posts ? As far as I can see from a quick look it´s not really different to get_posts() with standard values at all.

Besides that your lines 91 and 92 could be the troublemaker.

foreach ($recent_posts as $post) {
$categories = get_the_category($post->ID);

I think, $post is really bound to the current post you are looking at. That is no big thing on the homepage, but once you view an article, your loop-$post could be overwritten by the blogpost-$post (you know what I mean?).

Try changing those to something different than $post , that might solve your problem.

Answer 2

foreach ($recent_posts as $post) {
$categories = get_the_category($post->ID);

insteadof you can use, this one belown.

because $post is a global varaiable.

Example:

    $categories = get_the_category($post->ID);

    foreach ($categories as $cat) {

        echo $cat->cat_name;
    }
