show empty categories (new thread)

[jablka]

hi there

I tried to use the easiest way described here https://www.ads-software.com/support/topic/how-to-show-empty-categories-in-28?replies=3
but didn’t worked..

however when I used this code:

<ul>
<?php wp_list_categories( array( 'show_count' => 1 , 'hide_empty' => 0 ) ); ?>
</ul>

from https://www.ads-software.com/support/topic/show-empty-categories
and pasted it somewhere in “header.php” it showed successfully even hidden categories…

so I need to apply it similarly to my sidebar. I’m using category widget (in my sidebar).

so I would probably need to know where exactly WordPress calls the “show categories” function from sidebar.php or widgets.php or similar, to adjust the code. can anyone help?

okay, I resolved it

the problem was, that the ‘hide_empty’ parameter occurs in
wp-includes/category-template.php twice, in different functions:

function wp_dropdown_categories
and function wp_list_categories

so be sure to change the appropriate one. (I changed both for sure now ??

do not edit WordPress core files;
the least problem is that these edits get overwritten (lost) when you next upgrade the WordPress version;
the worst case is that you break the whole WordPress installation, so that you need to re-instal all.

for manipulating the ‘Categories’ widget, use a filter function as discribed here: https://www.transformationpowertools.com/wordpress/edit-widget-parameters-filter-wordpress

example:

add_filter('widget_categories_args','show_empty_cats_category_widget');
function show_empty_cats_category_widget($args) {
$args['hide_empty'] = 0;
return $args;
}

hi alchymyth

i am using this (<?php wp_dropdown_categories ();?>) function in my coade
it’s binding the category but not clickable. plz sort out this problem.

But isn’t there a global way to show all empty categories whether it is in a widget/sidebar, nav bar, header, or just on a page. I have looked through countless forms and it seems like no one is answering this core question.

I want to be able to click a category on a page that opens to its sub categories, that which then opens to their children that eventually reaches a final post. (like a tricking effect of links that narrow itself down through categories)

Why is this so difficult to do?
Anyone?
