   Hello,

   I'm building a custom theme and in the homepage (index.php), I'm showing 4 posts from different categories.

   All is working OK with get_posts, the title and the content are shown as normal ; only the tags fail to appear.

   If I set up a conventional Loop, the tags show again.

   Here it is one of my loops, the others are 'clons' but changing the category :
   

   <?php
   	 $posts = get_posts('category=6&numberposts=1');
   	 foreach($posts as $post):
   		setup_postdata($post);
   	 ?>
   	<?php the_title(); ?>
   	<?php the_content(); ?>
   	<?php the_tags(); ?>
   	<?php endforeach; ?>

   I've tried to do the same through WP_query, with no results :

   <?php $my_query = new WP_Query('showposts=1&cat=4'); ?>
   	<?php if (have_posts()) : while ($my_query->have_posts()) : $my_query->the_post(); ?>
   	<?php the_title(); ?>
   	<?php the_content(); ?>
   	<?php the_tags(); ?>
   	<?php endwhile; endif; ?>

   I have several times worked with both, get_posts and WP_query (even if I ignore their differences, which it could be cool to know), and I don't remember any issue.

   Finally I tried to put a rewind_posts function, which I think it protects several Loops to 'contaminate' each other, but with no difference :

   <?php get_header(); rewind_posts(); ?>

   Thanks for any input if anybody have some idea.

   Hi stvwlf, thanks for that link, with this other thread, it gave me an idea of what was happening.

   Here's my final code. It seems like I needed to specify the called post's ID to acces to its tags.

   <?php
   		 $posts = get_posts('category=4&numberposts=1');
   		 foreach($posts as $post):
   			setup_postdata($post);
   		 ?>
   		<?php the_title(); ?>
   		<?php the_content(); ?>
   
   		<!-- HERE IT COMES THE TRICKY PART -->
   
   		<?php $posttags = get_the_tags($post->ID);
   		if ($posttags) {
   		foreach($posttags as $tag) {
   		echo $tag->name . ' ';
   		}
   		}
   		?>
   		<?php endforeach; ?>

   It works the same with WP_query.

   By the way, does someone knows the main differences between WP_query and get_posts ? Which is quicker, or better ? why two functions ?

   I'm looking now for a way to get the tags linking to its archive pages :/

   <?php $posttags = get_the_tags($post->ID); if ($posttags) {
   foreach($posttags as $tag) {
   echo '<a href="';
   echo get_tag_link($tag);
   echo '">';
   echo $tag->name . ' ';
   echo '</a>';
   }
   }
   ?>

   This is working for me, but I'm suspicious 'cause it must be a cleaner mode to get it. Please don't hesitate to make your remarks.

   Dunkkan: thanks for the info. Not sure what you meant by "a cleaner mode", because this looks similar to the examples given from WordPress here:
   http://codex.wordpress.org/Template_Tags/get_the_tags

   Anyways, I wanted to be able to have it separated by commas, so I used this:

   <?php
   $posttags = get_the_tags($post->ID);
   if ($posttags) {
   /*Define counter*/
   $counter = 0;
     foreach($posttags as $tag) {
     /*Add to counter*/
     $counter++;
      echo '<a href="';
      echo get_tag_link($tag);
      echo '">';
      echo $tag->name;
      echo '</a>';
      /*If you're at the last tag, do nothing.  Otherwise, add a comma and a space.*/
      if(!($counter < count($posttags))){
       /*Do nothing*/
      }else{
       echo ', ';
      }
     }
   }
   
   ?>

   Hope that helps someone else too! ;) And, thanks again Dunkkan!
