   Hello

   For single post I want to create a conditional to bring in certain sidebars according to the categroy that the post is in.

   For example I would like to call in the sidebar_music.php when the post is in either music or a subcategory (child) of music. Music is a section or category of my site and is assigned cat ID 5

   Thus the music sidebar would appear in both these cases
   http://mysite.com/music/article
   http://mysite.com/music/concerts/article

   I assume the code would look something like this. I am a novice with PHP so I don't know the correct syntax but the perintent functions and logic are basically here. My main problem is I do not know how to define the category and ALSO the children of that category within this conditional.

   <?php

   if(is_category('5&&child_of=5'))

   include ('music_sidebar.php');

   elseif (is_category(9&&child_of=9))

   include ('tv_sidebar.php');

   elseif (is_category(8&&child_of=8))

   include ('dining_sidebar.php');

   ?>

   You would use in_category. Also see: http://codex.wordpress.org/Include_Tags

   See the examples here..

   http://codex.wordpress.org/Template_Tags/in_category

   Examples show how to check if is descendant(child)..

   TIP: regarding your code... it wasn't far off...

   if(something) {
   do this
   } else {
   do that
   }

   or

   if(something) :
   do this
   else :
   do that
   endif;

   You need to enclose your if/else statements....

   I personally found the curly brackets { and } easier when i started on PHP...

   Both are valid, no reason to use one over the other, just use which you prefer...
