passing current single_tag_title as variable into new wp_query

Maybe something like this.

Replace this:

<?php $current_tag = single_tag_title(); ?>

With this:

<?php
	global $wp_query;
	$tag = $wp_query->get_queried_object();
	$current_tag = $tag->term_id;
?>

This should work with the WordPress Default Theme’s index.php:

<?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) {
  echo 'Related Posts';
  $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(); ?>
      <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
      <?php
    endwhile;
  }
}
?>

Thanks so much MichaelH, I can’t tell you how much I appreciate your help. Was that information listed in a doc somewhere? If so I missed it. Please post the link if there is one. Thanks again.

No, just coded that for you.

Ahh! I just realized what I coded was for tag archive pages. Where’s my head at? ??

@greenshady: well you’ve got a million other good ideas and code examples, Justin…

patcheta: saw something yesterday that should probably be changed/added at the end of the code there, adding the wp_reset_query so it doesn’t blowup the_post in your regular loop.

<?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) {
  echo 'Related Posts';
  $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_title(); ?></a>

      <?php
    endwhile;
  }
wp_reset_query();
}
?>

You guys are awesome. Thanks so much!

hi, can i request to you the same for Recent Post frome the same category? I am working with this code outside the loop (only category but goes with author too), but yours seem very better.

<?php

//Gets category and author info
global $wp_query;
$cats = get_the_category();
$postAuthor = $wp_query->post->post_author;
$tempQuery = $wp_query;
$currentId = $post->ID;

// related author posts
$newQuery = “posts_per_page=5&author=” . $authorPosts;
query_posts( $newQuery );
$authorPosts = “”;
$count = 0;
if (have_posts()) {
while (have_posts()) {
$count++;
the_post();
if( $count<4 && $currentId!=$post->ID) {
$count++;
$authorPosts .= ‘

• ‘ . the_title( “”, “”, false ) . ‘

‘;
}
}
}

// related category posts
$catlist = “”;
forEach( $cats as $c ) {
if( $catlist != “” ) { $catlist .= “,”; }
$catlist .= $c->cat_ID;
}
$newQuery = “posts_per_page=5&cat=” . $catlist;
query_posts( $newQuery );
$categoryPosts = “”;
$count = 0;
if (have_posts()) {
while (have_posts()) {
the_post();
if( $count<4 && $currentId!=$post->ID) {
$count++;
$categoryPosts .= ‘

• ‘ . the_title( “”, “”, false ) . ‘

‘;
}
}
}
$wp_query = $tempQuery;
?>
<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<h2>Ultimos artículos de la categoría: <?php the_category(‘, ‘);?></h2>

• <?php echo $categoryPosts; ?>

<?php endwhile;?>

I have been looking high and low for an answer to my problem which is related to above.

In my template I am displaying a page and wanting to show groups of related posts on the right. Each group is a category and each post is also tagged with a keyword. In this particular part of my site I am using the title of the page as the match for the keyword. Example might be category of “Quick Tips” for tag equaling “Foo”. I would want that post listed when on the “Foo” page.

Here’s the code.

<?php
			$args ="cat=80&amp;tag=".$mypage_title."&amp;showposts=5";
			echo ($args);
			$recent = new WP_Query($args);

		if ($recent->have_posts()) {
			?><h4>Quick Tips</h4>
			<ul>
			<?php
			while($recent->have_posts()) : $recent->the_post();
				//if (has_tag($mypage_title)) {
				if (get_post_meta($post->ID, 'flv', true)) {
				?>
				<li><a class="sidebarnav1" href="<?php the_permalink()?>"><img width="20" src="/wordpress/wp-content/themes/revolution_business-10/_images/video2.jpeg"> <?php the_title(); ?></a></li>
				<?php }else{ ?>
				<li><a class="sidebarnav1" href="<?php the_permalink()?>"><?php the_title(); ?></a></li>

				<?php }//}
			endwhile; ?>
			</ul>

When I use add the “tag=????” I stopped getting back any posts. I have echo’d my $args and they do contain the page title. I got page title using

$mypage_title = trim(wp_title('',false,''));

What am I doing wrong that combining category and tag won’t work?

Thanks for any help!

Wes

Hi MichaelH,

This code is great, but for some reason if there is a comment for the last relevant post, it puts that into comments section..?

Is there something i’m missing here?

Hey Michael H,

Is there any way to change the code you made from ‘first tag’ to display 5 posts related (randomly) to ALL of the current post’s tags?

Thanks!

@michaelh
I have the same problem with the code, the comments displayed come from the last post in the similar posts list. What can I do about it?

I found the solution myself. Here: https://www.3mind.at/2009/05/06/code-highlighting/

Backup the current $post object at the beginning of our code and copy it back at the end, where you also call the built-in function wp_reset_query().

<?php //for use in the loop, list 5 post titles related to first tag on current post
$backup = $post; // backup the current object
$tags = wp_get_post_tags($post->ID);
$tagIDs = array();
if ($tags) {
$tagcount = count($tags);
for ($i = 0; $i < $tagcount; $i++) {
$tagIDs[$i] = $tags[$i]->term_id;
}
$args=array(
‘tag__in’ => $tagIDs,
‘post__not_in’ => array($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(); ?>
<h3>” rel=”bookmark” title=”<?php the_title(); ?>”><?php the_title(); ?></h3>
<?php endwhile;
}
}
$post = $backup; // copy it back
wp_reset_query(); // to use the original query again
?>
