tax images plus wp_list_categories

Hello guys !

First, thanks a lot Michael for providing such a useful plugin. So far it’s working like a charm. I used the aforementioned function on a taxonomy archive, and it’s working great !

However, it only displays the terms which actually *have* an image associated with them, despite the fact I’d like to display the terms which haven’t, too (it would be a great plus to be able to display a default image, in that case).

Ideal scenario would be :

1. if the term has an image attached, display the thumbnail size ;
2. if the term hasn’t an image attached, display a default image.

I’ve tried the following code, so far with no success:

<?php
$terms = apply_filters( 'taxonomy-images-get-terms', '', array(
	'taxonomy' => $post->post_name,
	) );
$image_url = apply_filters( 'taxonomy-images-queried-term-image-url', '', array('image_size' => 'full') ); 

if ( ! empty( $terms ) ) {
	print "\n" . '<ul>';
	foreach( (array) $terms as $term ) {
		print "\n" . '<li>';
		if ( ! empty ($image_url) ) {
			print "\n\t" . '<a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '"><img src=' . $image_url . '</a>';
			print "\n\t" . '<span class="category-name">' . esc_html( $term->name ) . '</span>';
		} else {
			print "\n\t" . '<a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '"><span class="category-name">' . esc_html( $term->name ) . '</span></a>';
		}
		print "\n" . '</li>';
	}
	print "\n" . '</ul>';
}
?>

NB : $post->post_name allows me to dynamically retrieve the taxonomy name.

Any help would be much appreciated ! 🙂 Many thanks in advance.

Thanks a lot ! 🙂

Unfortunately it doesn’t change anything : only the terms which already have an image attached are showing up. The other terms don’t, as though the else statement wasn’t working.

Edit : wait, I’ve tried on another taxonomy archive page, and it’s working ! I will compare the taxonomy settings to find what’s the problem on my first taxonomy. I’ll keep you updated.

Here we go :

Let’s say I have one cutom post type called “Movies”, and one custom taxonomy called “Directors” associated to this custom post type.

When I browse http://www.mydomain.com/movies/, I do have an archive page with all my custom posts filed under “Movies”. However, when I browse http://www.mydomain.com/directors/, I get a 404 page since taxonomies don’t have an automatic archive page url.

That’s why I create the “Directors” page on which I use a custom template called “taxonomy-tagcloud.php” (whatever the name).

My goals are :

1. Display the Taxonomy name as h1 ;
2. Display a short description (= the Page content) ;
3. Then, display the list of terms under the “Directors” taxonomy :

1. if the term has an image attached : display it ;
2. if the term doesn’t have an image attached, display a default image.

That’s all, basically.

Here is the complete taxonomy-tagcloud.php :

<?php
/**
 * @package WordPress
 * @subpackage Toolbox
 */

get_header(); ?>

		<div id="primary">
			<div id="content" role="main">

				<?php // here, the page title and content ?>
				<?php the_post(); ?>
				<?php get_template_part( 'content', 'page' ); ?>

				<?php //here, the code to display all terms with their own image, otherwise with the default image ?>
<?php
// I use $post->post_name to dynamically get the page's slug, i.e "directors"
$terms = apply_filters( 'taxonomy-images-get-terms', '', array(
	'taxonomy' => $post->post_name,
) );

if ( ! empty( $terms ) ) {
	print "\n" . '<ul>';
	foreach( (array) $terms as $term ) {
		print "\n" . '<li>';
		if ( ! empty ( $term->image_id ) ) {
			print "\n\t" . '<a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '">' . wp_get_attachment_image( $term->image_id, 'detail' );
			print "\n\t" . '<span class="category-name">' . esc_html( $term->name ) . '</span>';
		}
		else {
			print "\n\t" . '<a href="' . esc_url( get_term_link( $term, $term->taxonomy ) ) . '"><img src="http://dummyimage.com/150/000/fff.png">';
			print "\n\t" . '<span class="category-name">' . esc_html( $term->name ) . '</span>';
		}
		print "\n" . '</li>';
	}
	print "\n" . '</ul>';
}
?>

			</div><!-- #content -->
		</div><!-- #primary -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Now, I made some other tests, and here is the problem I get with this code :

• if the taxonomy contains only one term, and if this only term doesn’t have any image attached, then the code works : I get the default image and the term link ;
• if the taxonomy contains many terms, and if at least one of these terms does have an image attached, then the terms without any image attached don’t show.

Do you have any idea about what the problem could be ?

PS : of course, I’m open to any other solution. Maybe using a page to achieve this isn’t the right way ? I’m close to get it working, though.

Thank you so much ! It works perfectly \m/

You’re very welcome, d.keeling! I’m happy my solution was useful to you 🙂

an update: wow!

did not think that could be even simplier..

anyways, i just copied the above code, and everything works now!!!
thanks anyway 🙂
