related taxonomy thumbnail for custom post type

Resolved

(@davidedante)

Hi all,
I am trying to build a design portfolio theme, I set up a custom post type named ‘portfolio’ and a custom taxonomy (for instance I will have wed design, product design etc.). I got a way to display a list of related taxonomy but I am not able to add the thumnail to related content to be displayed at the end of single custom post page.

that’s the code I actually have (inside single-portfolio.php), does anyone know hot to display thumbnails too?

<?php
$sectors = get_the_terms( get_the_ID(), 'skills' );
if ( ! is_wp_error( $sectors ) ) {
	$term = array_shift( $sectors );

	/* Query */
	$jobs = null;
	if ( isset( $term->slug ) && isset( $term->taxonomy ) ) {
		$jobs = get_posts( array(
			'term'        => $term->slug,
			'taxonomy'    => $term->taxonomy,
			'post_type'   => 'portfolio',
			'post_status' => 'publish',
			'exclude' => get_the_ID(), /* exclude current project */
			) );
	}

	/* Loop */
	if ( $jobs ) {
		$_post = $post;
		print '<div id="related">' . "\n". '';
		foreach ( (array) $jobs as $post ) {
			setup_postdata( $post );
			the_title( '	<div class="related"><a href="' . esc_url( get_permalink() ) . '">', '</a></div>' . "\n". '' );
		}
		print '</div>';
		$post = $_post;
	}
}

ok, have no clue about how I did it but mixing a ‘related post by tag’ code and the one above I got what I was looking for.
Now, since I have no php programming skills maybe you guy could just tell me if the following code is ‘correct’, I mean, it seems to provide the right output (on MAMP), but it is useful to understand if it is a ‘clean’ code that a third person searching this thread can safely use for another theme.

<?php $orig_post = $post;
global $post;
$tags = get_the_terms( get_the_ID(), 'skills' );
if ($tags) {
	$tag_ids = array();
	foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;
	$args=array(
		'term'        => $term->slug,
		'taxonomy'    => $term->taxonomy,
		'post_type'   => 'portfolio',
		'post_status' => 'publish',
		'exclude' => get_the_ID(), /* exclude current project */
		'post__not_in' => array($post->ID),

	);
	$my_query = new wp_query( $args );

	/* Loop */
	if( $my_query->have_posts() ) {

		echo '<div id="relatedposts"><h3>Related Posts</h3><ul>';

		while( $my_query->have_posts() ) {
			$my_query->the_post(); ?>

			<li>
				<div class="relatedthumb"><a href="<? the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_post_thumbnail(); ?></a></div>
				<div class="relatedcontent">
				<h3><a href="<? the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3>
				<?php the_time('M j, Y') ?>
				</div>
			</li>
		<? }
		echo '</ul></div>';
	}
}
$post = $orig_post;
wp_reset_query(); ?>

mhh.. I didn’t see that actually this code shows all the custom post without filtering it by current single post taxonomy, this is the code I am using right know, can you guys help me to understand how to exclude not related taxonomy posts?

<!-- related projects -->

<?php $orig_post = $post;
global $post;
$tags = get_the_terms( get_the_ID(), 'skills' );
if ($tags) {
	$tag_ids = array();
	foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;
	$args=array(
		'term'        => $term->slug,
		'taxonomy'    => $term->taxonomy,
		'post_type'   => 'portfolio',
		'post_status' => 'publish',
		'post__not_in' => array($post->ID),

	);
	$my_query = new wp_query( $args );

	/* Loop */
	if( $my_query->have_posts() ) {

		echo '<div id="relatedposts">
	<h3>Related Posts</h3>';

		while( $my_query->have_posts() ) {
			$my_query->the_post(); ?>

	<div class="post-thumb">
		<a href="<? the_permalink()?>" rel="bookmark" title="">
			<div class="view">View</div>
			<?php
				if(has_post_thumbnail()) {
					the_post_thumbnail();
				} else {
					echo '<img src="'.get_bloginfo("template_url").'/images/default-thumbnail.png" />';
				}
			?>
		</a>
	</div>
		<div class="relatedcontent">
		<h4><a href="<? the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h4>
	</div>
		<? }
		echo '</div>';
	}
}
$post = $orig_post;
wp_reset_query(); ?>

Try it with a tax_query: https://codex.wordpress.org/Function_Reference/WP_Query#Taxonomy_Parameters

example [untested]:

$args = array(
  'post_type'   => 'portfolio',
  'post_status' => 'publish',
  'post__not_in' => array($post->ID),
	'tax_query' => array(
		array(
			'taxonomy' => $individual_tag->taxonomy,
			'field' => 'slug',
			'terms' => array($individual_tag->slug)
		)
	)
);
$my_query = new WP_Query( $args );

thank you for your reply guys,
keesiemeijer, your tip worked!

so, as you said, instead of

'taxonomy'	=> $term->taxonomy,
'field'		=> 'slug',
'term'		=> $term->slug,

I have to write this:

'tax_query' => array(
			array(
				'taxonomy' => $individual_tag->taxonomy,
				'field' => 'slug',
				'terms' => array($individual_tag->slug)

so the whole thing become

<?php $orig_post = $post;
global $post;
$tags = get_the_terms( get_the_ID(), 'skills' );
if ($tags) {
	$tag_ids = array();
	foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;
	$args = array(
		'post_type'   => 'portfolio',
		'post_status' => 'publish',
		'post__not_in' => array($post->ID),
		'tax_query' => array(
			array(
				'taxonomy' => $individual_tag->taxonomy,
				'field' => 'slug',
				'terms' => array($individual_tag->slug)
			)
		)
	);
	$my_query = new WP_Query( $args );

	/* Loop */
	if( $my_query->have_posts() ) {

		echo '<div id="relatedposts">
	<h3>Related Posts</h3>';

		while( $my_query->have_posts() ) {
			$my_query->the_post(); ?>

	<div class="post-thumb">
		<a href="<? the_permalink()?>" rel="bookmark" title="">
			<div class="view">View</div>
			<?php
				if(has_post_thumbnail()) {
					the_post_thumbnail();
				} else {
					echo '<img src="'.get_bloginfo("template_url").'/images/default-thumbnail.png" />';
				}
			?>
		</a>
	</div>
		<div class="relatedcontent">
		<h4><a href="<? the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h4>
	</div>
		<? }
		echo '</div>';
	}
}
$post = $orig_post;
wp_reset_query(); ?>

I am going to close the thread, meanwhile can you explain how this change solved the issue (I’d like to have a better PHP understandment)?

In your query ($args) you used “term” which isn’t a WP_Query parameter: https://codex.wordpress.org/Function_Reference/WP_Query#Parameters

And you got the taxonomy and term slug from the foreach: foreach($tags as $individual_tag) { ... }, so you have to use “$individual_tag” and not “$term” as the variable to get the term’s taxonomy and slug.

I’m glad you got it resolved.
