   Hi

   I found this very useful piece of code in this thread - It tests whether a category has posts in.

   $test=get_posts('category_name=test');
   if ($test) {
   //found posts
   }

   How could I turn this into a function, so I can use it anywhere?
   Would it be something like this in functions.php..

   function test_category($cat) {
   $test=get_posts('category_name=$cat');
   }

   ... so then I could use it like this in the template...

   <?php if (test_category('category to be tested')) {
   ?>

   Its so I can test any category on the fly, rather than putting in the whole code. Please bear in mind that I have no idea how to write functions, but I'm trying to learn so I thought I'd give it a go! this is as much to learn how to writ a function as it is to get the answer...

   example:

   function test_category($cat_name='') {
   if( $cat_name && get_posts('category_name=' . $cat_name) ) return true;
   else return false;
   }
