# PHP if elseif problem

 * I’m modifying a theme to better suite my needs, but run into a mysterious problem.
   In my sidebar.php I have:
 *     ```
       <?php
         if (is_front_page() and dynamic_sidebar('Home Page')) { }
         elseif (is_page() and dynamic_sidebar('Page Default')) { }
         elseif (is_single() and dynamic_sidebar('Single Post')) { }
         else { }
       ?>
       ```
   
 * But for some reason this does not work. WordPress does not even compile (if that
   is the correct term) my sidebar.php when it looks like that. But when I remove
   one of the lines beginning with “elseif” statements, sidebar.php compiles and
   theme works nicely (only missing the removed functionality).
 * Could someone please tell me what is wrong with my code.

 * This may not address your issue – but try replacing “and” with “||”

 * It looks like it is the line
 *     ```
       elseif (is_single() and dynamic_sidebar('Single Post')) { }
       ```
   
 * which is causing problems. Perhaps the “is_single()” function, because I tried
   to change the “Single Post” sidebar to another, but no luck. I’ll continue debugging
   tomorrow.

 * Replacing “and” with “||” would break the logic in the code. I want the sidebar‘
   Home Page’ to be loaded to my front page, sidebar ‘Page Default’ to any other
   page and ‘Single Post’ when user browses to any single post.
 * If I replace “and”s with “||” sidebar ‘Home Page’ would be shown in any situation.

 * Could be I misused the is_single() function here. I should use the is_post() 
   instead. is_single need an argument also to check if a particular post is displayed,
   but I just need to find out if any post is displayed.

 * Perhaps what ws5f3dj7 meant was ´&&´ and not ´||´
