WordPress: Show categories the searched posts are in

1. As you have not provided any code, I tried in my way.I guess, It is not the best way to achieve it but as of now, you can do in that way.

   Here, I have used PHP to achieve your desired result.

   I have used Twenty Fourteen theme’s search.php.

   Here is my code for the search.php of Twenty Fourteen theme and you can implement in your search file :

       <?php
       /**
        * The template for displaying Search Results pages
        *
        * @package WordPress
        * @subpackage Twenty_Fourteen
        * @since Twenty Fourteen 1.0
        */
   
       get_header(); ?>
   
           <section id="primary" class="content-area">
               <div id="content" class="site-content" role="main">
   
                   <?php if ( have_posts() ) : ?>
   
                   <header class="page-header">
                       <h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'twentyfourteen' ), get_search_query() ); ?></h1>
                   </header><!-- .page-header -->
   
                       <?php 
   
                           // Start the Loop.
                           $post_id_array = array(); //Blank array to store all Post IDs
   
                           while ( have_posts() ) : the_post(); 
   
                               array_push($post_id_array, $post->ID); //store ID to array
   
                               /*
                                * Include the post format-specific template for the content. If you want to
                                * use this in a child theme, then include a file called called content-___.php
                                * (where ___ is the post format) and that will be used instead.
                                */
                               get_template_part( 'content', get_post_format() );
   
                           endwhile;
                           // Previous/next post navigation.
                           twentyfourteen_paging_nav();
   
                           $catarray = array(); //Blank array to store all categories
                           $k=1;
                           foreach($post_id_array as $my_post){
                               $my_category = get_the_category( $my_post );
   
                               foreach($my_category as $my_cat){
                                   array_push($catarray, $my_cat->cat_name); //Store category in array
                               }
   
                               $something = array_count_values($catarray); //Count total number of element in category array
   
                               foreach(array_unique($catarray) as $some){
                                   if($k == sizeof($my_category) ): //Condition to print all thing if only it is last element of an array.
                                       echo $some."(". $something[$some].")<br>";
                                   endif;
                               }
                               $k++;
                           }
                       else :
                           // If no content, include the "No posts found" template.
                           get_template_part( 'content', 'none' );
   
                       endif;
                   ?>
   
               </div><!-- #content -->
           </section><!-- #primary -->
   
       <?php
       get_sidebar( 'content' );
       get_sidebar();
       get_footer();
   

   Here in above code, I have done :

   Step-1 : Take one blank array to store ID of the posts that are given by the search query.

   Step-2 : Push all the IDs in to created blank array with PHP’s array_push function. NOTE: Make sure you have put it in a while loop to get all the ID.

   After two steps, now you have an array of all the post IDs.

   Step-3 : Take another blank array to store related category name of the post.

   Step-4 : Take one variable and give its value to 1 which is useful at the end.(I have taken $k = 1).

   Step-5 : Make one foreach loop of Post IDs. And get category name of the posts with wordpress function get_the_category.It will fetch category based on post ID.

   Step-6 : Now its time to use the blank array that we have created for category name.So just loop through category name and store name of the category in to an array.

   Step-7 : Count total names in the category array with PHP’s array_count_values function and assign variable to it.(I have used $something).

   After step-7, we have an array of category name. Note: Here in this array, there might be duplication of category name.To remove duplication follow next step.

   Step-8 : Use PHP’s ‘array_unique’ function to get only unique value from an array.

   Step-9 : Make a loop of the category name.

   If you echo right now, it will print categories to total number of post times.

   So now its right time to use the variable that we have taken before foreach loop of post ID($k=1).

   Last step : Now make one condition to print all categories at the last post.

   So for that I have used if($k == sizeof($my_category) ) which means that, It will only print when length of an category array equal to the variable K(In short, in the end).

   Increase the value of $k.

   Hope it helps you. Ask me If you have any doubt.
