    hi
    i have this code in the loop that reads the tags in a post and if it finds one in particular “Peace initiatives” it then changes the div class and the border goes grey.

    <?php
               $post_class="post";
			   $tags=get_the_tags($id);
               foreach ($tags as $key => $post_type)
               {
                  $tag_str=$post_type->name;
                  if (stripos($tag_str,'Peace initiatives')) {
                          $tag_str="Peace initiatives";
                  }
                  switch ($tag_str)
                  {
                       case 'Peace initiatives':
                           $post_class="post-peace";
                           break;
                  }
               }
             ?>

    after upgrading i get a crazy error sometimes, not everytime that says:

    Warning: Invalid argument supplied for foreach() in /…/wp-content/themes/pact-by-cezar/index.php on line 31

    the line is the foreach line i use above. have the $tags arguments changed in wp 2.5?
    can anyone help me out? the blog is here: http://www.pact.lk
    thanks

    C

    Do you have any posts that don’t have any tags?

    foreach ($tags as $key => $post_type)

    That code will be invalid if $tags is not an array, which it won’t be if there are no tags on a post.

    hi thanks for the reply Otto.
    indeed on the pages i dont have. maybe also a few posts. so in search results if a result is from a page it brings this warning.

    any idea how i could correct this?
    thank you for the help.

    Try this.

    ...
if (!empty($tags)) foreach ($tags as $key => $post_type)
...
