However, instead of adding to comment discussion and making more mistakes, I’ll write out an answer. function slider_news() { $num = 0; $args = array( ‘numberposts’ => 3 ); … Read more
Look at your filter: apply_filters(‘change_number_of_posts_home’, $posts_per_page) The value being passed to it is $posts_per_page, so of course they can’t change $number. If you want only the number to be filtered then that’s the part that should have the filter applied: $number = apply_filters(‘change_number_of_posts_home’, 3 ); Then the query can just look like this: $wp_query->query( ‘post_per_page=” … Read more
This is a non issue if you use PHP 7.0+ that keeps all files compiled in memory (not 100% accurate but a good enough abstraction), and since all other PHP versions are not supported or are very near their End Of Life, you should upgrade to 7.0+ version if you are not on one. Regardless, … Read more

And secondly, is this a global WordPress feature, or do plugin developers have to build this functionality into the plugin? It’s not a WordPress feature. Not exactly. Each plugin that does this has created their own function for loading template files … Read more
It’s worth noting that PHP namespace issues can contribute to this problem. This can catch people because namespaces have been kept out of WordPress core codebase until recently. For example one of your code files may have a Namespace declaration around the top. If that is the case you will have to prefix any references … Read more
Good morning! This filter should work add_filter(‘show_admin_bar’, ‘__return_false’); right from the wordpress codex. Alternatively, you can disable it from specific users.
WordPress fires a number of different hooks when a post is (published / updated / saved). It’s usually best to browse through the Codex to determine which hook fires when, and only when, you want to run your custom code.
