# single.php and Categories

 * [17 years, 7 months ago](https://wordpress.org/support/topic/singlephp-and-categories/)
 * On my single.php page I want to have the tab of the article’s corresponding category
   highlighted.
 * For example: [http://embeddedcomputingsystems.com/](http://embeddedcomputingsystems.com/)
 * If the article is from “Boards” (the second tab next to “Home”) then I’d like
   the Boards tab to be in the active state. I’m am guessing I’d use some sort of
   php if statement, like if category=3 then class=”active” but am unsure of how
   to write this. I know nothing about php!
 * Can someone please help?
 * Thanks,
 * Jon

 * I was able to find this code:
 *     ```
       <?php
       if (is_category(9)) {
          // looking for category 9 posts
          include(TEMPLATEPATH . '/single2.php');
       } else {
          // put this on every other category post
          include(TEMPLATEPATH . '/single1.php');
       }
       ?>
       ```
   
 * Can I just keep adding if statements? for each category before the else?

 * In other words… is this valid:
 *     ```
       <?php
       if (is_category(1)) {
          // looking for category 1 posts
          include(TEMPLATEPATH . '/single1.php');
       if (is_category(9)) {
          // looking for category 2 posts
          include(TEMPLATEPATH . '/single2.php');
       if (is_category(9)) {
          // looking for category 3 posts
          include(TEMPLATEPATH . '/single3.php');
       if (is_category(9)) {
          // looking for category 4 posts
          include(TEMPLATEPATH . '/single4.php');
       } else {
          // put this on every other category post
          include(TEMPLATEPATH . '/single.php');
       }
       ?>
       ```

 * For posts, use in_category instead of is_category.

       include(TEMPLATEPATH . '/single2.php');
       }elseif ( in_category('3') ) {
       include(TEMPLATEPATH . '/single1.php');
       } else {
