   Hi,
   I use the code below to display in my blog page only the last post from each category and IT WORKS PERFECTLY
   

   <?php // cycle through categories, print 1 post for each category
   $categories=get_categories('orderby=&order=ASC&');
     foreach($categories as $category) {
         $posts=get_posts('showposts=1&cat='. $category->term_id);
   
           foreach($posts as $post) {
             setup_postdata($post); ?>

   So I have i.e :
   Category A --> Last post (a)
   Category B --> Last post (b)
   Category C --> Last post (c)
   .....

   If I publish a post that belongs to Category A and B, in the home page I'll get
   Category A --> Last post (a)
   Category A --> Last post (a) - same post above
   Category C --> Last post (c)

   Is there a way to keep the category B to show up with the last post as before, and only the Category A to show up with the post just published?

   <?php // cycle through categories, print 1 post for each category
   $categories=get_categories('orderby=&order=ASC&'); $duplicates = array();
     foreach($categories as $category) {
         $posts=get_posts(array('showposts' => 1, 'post__not_in' => $duplicates, 'category__in' => array($category->term_id)));
   
           foreach($posts as $post) {
             setup_postdata($post); $duplicates[] = $post->ID; ?>

   Thanks for your answer
   The code you provided didn't do the trick, I'll explain what happened, now I have:

   Category A --> Last post (a)
   Category A --> Second last post (a)

   Here it's the php file I'm using, it may help my explanation http://pastebin.com/DKJQh3ts

   I think something is wrong with category titles too.

   Thanks

   you could try different parameters:

   $posts=get_posts(array('numberposts' => 1, 'post__not_in' => $duplicates, 'category__in' => array($category->term_id)));

   or

   $posts=get_posts(array('posts_per_page' => 1, 'post__not_in' => $duplicates, 'cat' => $category->term_id));

   I tried to play a bit with the code, and added a tag="featured" to show up only post with featured tag in the blog page.

   I get post not duplicated and it's great alchymyth but I get Category title and category link duplicated, so maybe it's because of the code right below the previous code. See here highlighted please

   Can I use something to not duplicate category too?
