Show posts with same tags as current single post

    Hi

    I’m building a theme where I’d like to display thumbnails linking to posts that has the same tags as the post you are currently viewing underneath.

    Say I have two categories “Cars” and “Motorcycles”, and a post tagged with “Red” and “Two-door”. When viewing that single post I’d like to display thumbnails of each and every single post tagged either “Red” or “Two-door”, wether they are in “Cars” or in “Motorcycles” or whatever.

    Found this script by MichealH on WP Recipes which is nearly what I want (great script though Micheal still!), but it only fetches posts that has the first tag not posts from every tag:

    <?php
//for use in the loop, list 5 post titles related to first tag on current post
$tags = wp_get_post_tags($post->ID);
if ($tags) {
$first_tag = $tags[0]->term_id;
$args=array(
'tag__in' => array($first_tag),
'post__not_in' => array($post->ID),
'showposts'=>5,
'caller_get_posts'=>1
);
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_post_thumbnail(); ?>
</a>
<?php endwhile; }
wp_reset_query();
}
?>

    So, anyone know how to tweak that code to show posts from all tags not only the first?

    Then, secondary, if anyone know how to edit the same code to work outside the loop, I’d be very grateful!

    Thanks in advance!

    <?php
//for use in the loop, list all posts with tags contained on current post, exlcuding the current post
$tags = wp_get_post_tags($post->ID);
if ($tags) {
  $term_ids=array();
  foreach($tags as $tag) {
    array_push($term_ids,$term->term_id);
  }
  $args=array(
    'tag__in' => $term_ids,
    'post__not_in' => array($post->ID),
    'post_type' => 'post',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'caller_get_posts'=> 1
  );
  $my_query = null;
  $my_query = new WP_Query($args);
  if( $my_query->have_posts() ) {
    echo 'List of Related Posts';
    while ($my_query->have_posts()) : $my_query->the_post(); ?>
      <a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_post_thumbnail(); ?></a>
      <?php
    endwhile;
  }
wp_reset_query();  // Restore global post data stomped by the_post().
}
?>

    Thanks a lot for getting back to me so quickly Micheal! Didn’t got your code to work though, but I just finished one myself that does, and it’s even working outside the loop;

    <?php global $post;
$nextTagThumb='-1';
$tags = wp_get_post_tags($post->ID);
foreach ($tags as $tag) :
?>

<?php
if ($tags) {
$what_tag = $tags[($nextTagThumb+'1')]->term_id;
$args=array(
'tag__in' => array($what_tag),
'post__not_in' => array($post->ID),
'showposts'=>100,
'caller_get_posts'=>1
);
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<li>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_post_thumbnail(); ?>
</a>
</li>
<?php endwhile;
}
wp_reset_query();
$nextTagThumb = ($nextTagThumb+1);
}
?>
<?php endforeach; ?>

    As you will see, it’s based on your original code, I just added a foreach loop for all the tags of the post and a variable that grows with each tagged post. Not sure how kosher my code is, and if you see an obvious error or issue please let me know, otherwise it’s doing the job.

    Thanks again for getting back to me, was going to post the code I just finished when I saw your post.

    @carl-johan and MichaelH – thanks for this. Most code only gets the first tag. This is perfect. Great work.

    Ah. It displays posts with the same tag twice. Is there a way to get display a post only once in this list, given that it might a different tags?

    I’ve sorted it sorry. I used the do not duplicate array coding from:
    http://codex.wordpress.org/The_Loop#Multiple_Loops

    set the array position 0 to be 1 and then go into the loop at the end of the lop set the current post id into the loop then check at the beginning of the loop if that post has already been inside this loop.
