categories - Show the amount of posts in a tag in a specific category has

I am creating a page template in Wordpress that displays multiple tags that are in a particular category. I have this working, but now I want to have the number of posts within each tag that is displayed as well like if I had a tag called apples with 5 posts it would look like this:

Apples(5)

As of now it just shows Apples

Here is my code I want to modify:

    <?php
      if (is_category()){
           $cat = get_query_var('cat');
           $yourcat = get_category ($cat);
       }
       $tag_IDs = array();
           query_posts('category_name=health');
                   if (have_posts()) : while (have_posts()) : the_post();
                       $posttags = get_the_tags();
                           if ($posttags):
                           foreach($posttags as $tag) {
                               if (!in_array($tag->term_id , $tag_IDs)):
                                   $tag_IDs[] = $tag->term_id;
                                   $tag_names[$tag->term_id] = $tag->name;
                                   endif;
                       }
                       endif;
                       endwhile; endif;
                   wp_reset_query();
       
               echo "<ul>";
               foreach($tag_IDs as $tag_ID){
               echo '<a href="'.get_tag_link($tag_ID).'">'.$tag_names[$tag_ID].'</a>';
               }
           echo "</ul>";
       ?>

function wp_get_postcount($id)
{
    $contador = 0;
    $taxonomia = 'categoria';
    $args = array(
        'child_of' => $id,
    );
    $tax_terms = get_terms($taxonomia,$args);
    foreach ($tax_terms as $tax_term){
        $contador +=$tax_term->contador;
    }
    return $contador;
}

The reason you get this is because you're using query_posts and looping over posts, not terms/categories.

So while you want this:

terms = child terms of health
for each term in terms
    print the term name
    print the number of posts in that term

What the code actually does is this:

posts = all posts that have the category health
for each posts
    print a list of tags this post has

query_posts, aside from being a function you should never use, fetches posts, not terms/categories. It does not make sense to fetch posts here.

So instead we need to do this:

healthterm = the health term
terms = child terms of health term
for each term in terms
    print the name
    print the post count

So first we get the health term:

$parent = get_term_by( 'slug', 'health', 'category' );

Then get its children with something similar to this:

$terms = get_terms( 'category', [
    'parent' => $parent->term_id
] );

And finally, loop over the terms and print their names/counts

if ( !is_wp_error( $terms ) && !empty( $terms ) ) {
    foreach ( $terms as $term ) {
        // ...
        echo $term->name . ' ' .$term->count;
    }
}

These are the missing building blocks you need to achieve your goal.

Here is the code I rewrote that solved my problem. It loops through a category and shows how many articles all the tags inside the category has.

<?php
                            $custom_query = new WP_Query( 'posts_per_page=-1&category_name=health' );
                            if ( $custom_query->have_posts() ) :
                                $all_tags = array();
                                while ( $custom_query->have_posts() ) : $custom_query->the_post();
                                    $posttags = get_the_tags();
                                    if ( $posttags ) {
                                        foreach($posttags as $tag) {
                                          $all_tags[$tag->term_id]['id'] = $tag->term_id;
                                          $all_tags[$tag->term_id]['name'] = $tag->name;
                                          $all_tags[$tag->term_id]['count']++;
                                        }
                                    }
                                endwhile;
                            endif;
    
                            $tags_arr = array_unique( $all_tags );
                            $tags_str = implode( ",", $tags_arr );
    
                            $args = array(
                                'smallest'  => 12,
                                'largest'   => 12,
                                'unit'      => 'px',
                                'number'    => 0,
                                'format'    => 'list',
                                'include'   => $tags_str
                            );
                            foreach ( $all_tags as $tag_ID => $tag ) {
                                echo '<a href="'.get_tag_link($tag_ID).'">' . $tag['name'] . '</a> ('; echo $tag['count'] . ')<br>';
                            }
                            wp_reset_query()
                         ?>
