    Hello!

    I need to display a list of terms from a Taxonomy of a Custom Post Type with some data of a Custom Field.

    From now on I have set up the CPT (article) with the Taxonomy (butlleti) and created a bunch of terms for this Taxonomy. I also created two Custom Fields (id 'mes_butlleti' and 'any_butlleti') for that Taxonomy (butlleti).

    Then, I managed to have this code that creates the list of terms:

    <?php
$terms = get_terms( array(
'taxonomy' => 'butlleti', // set your taxonomy here
'orderby' => 'date', // default: 'orderby' => 'name',
'order' => 'DESC',
'hide_empty' => false, // default: true
) );
if ( empty( $terms ) || is_wp_error( $terms ) ) {
return;
}
echo '<div class="butlletins__list-container">';
foreach( $terms as $term ) {
printf(
'<a href="%s">
    <div class="butlletins__list">
        <p class="p-big">ARTICLE N. <strong>%s</strong></p>
        <div class="butlletins__list-line"></div>
        <p> HERE I NEED TO PRINT THE TWO CUSTOM FIELDS </p>
    </div>
</a>',
esc_url( get_term_link( $term ) ),
esc_attr( $term->name )
);
}
echo '</div>';
?>

    I would like to print the data from both of the Custom Fields associated to the Taxonomy (butlleti) for each term.

    Is that possible? Can you give me some light?

    Thank you very much!!

    Hi,

    Please follow this topic to show the term meta https://support.metabox.io/topic/taxonomy-image-on-custom-post-type/

    and read more on the documentation https://docs.metabox.io/extensions/mb-term-meta/

    Hi Long Nguyen,

    Thanks for your help!

    I've been reading your documentation, but I can't figure it out how to make it work with the code I already have to show both the Terms and a Custom Field of that term.

    Could you please help me figure it out?

    Thank you!

    Hi,

    Here is an example to show the term meta in the loop

    foreach ( $terms as $term ) {
    $mes_butlleti= rwmb_meta( 'mes_butlleti', ['object_type' => 'term'], $term->term_id );
    echo $mes_butlleti; 
}

    Hi,

    That's great!

    Do you know how I can print $mes_butlleti and $any_butlleti into the HTML below?

    I would like to have those term data where it says <p>HERE I NEED TO PRINT THE mes_butlleti AND any_butlleti DATA<p>

    <?php
$terms = get_terms( array(
'taxonomy' => 'butlleti', // set your taxonomy here
'orderby' => 'none', // default: 'orderby' => 'name',
'order' => 'ASC',
'hide_empty' => true, // default: true
'number' => 1,
));
if ( empty( $terms ) || is_wp_error( $terms ) ) {
return;
}
echo '<div class="butlletins__list-container">';
foreach( $terms as $term ) {
    $mes_butlleti= rwmb_meta( 'mes_butlleti', ['object_type' => 'term'], $term->term_id );
    $any_butlleti= rwmb_meta( 'any_butlleti', ['object_type' => 'term'], $term->term_id );
    echo $mes_butlleti;
    echo $any_butlleti;
printf(
'<a href="%s">
    <div class="butlletins__list">
        <p class="p-big">BUTLLETÍ N. <strong>%s</strong></p>
        <div class="butlletins__list-line"></div>
        <p>HERE I NEED TO PRINT THE mes_butlleti AND any_butlleti DATA<p>
        <span class="butlletins__list-new">NOU</span>
    </div>
</a>',
esc_url( get_term_link( $term ) ),
esc_attr( $term->name ),
$term->count
);
}
echo '</div>';

?>

    Thanks!!!

    Hi!

    I rewrite all the code using echo, not printf, and now it works fine!

    Thanks for your help!

    Hello I tried to get something like to be have a list of all the taxonomy list in a sidebar widget but I get only a blank space of the item in hmtl content space.

    <?php
$terms = get_terms( array(
'taxonomy' => 'categorie', 
'orderby' => 'name', 
'order' => 'ASC',
'hide_empty' => true, 
));
if ( empty( $terms ) || is_wp_error( $terms ) ) {
return;
}
foreach( $terms as $term ) {
    $cat_title= rwmb_meta( 'categorie', ['object_type' => 'term'], $term->name );
	echo '<ul><li>';
    echo'<a href="'. get_term_link( $term ) .'">'. $cat_title . '</a>';
    echo '</li></ul>';
}
?>

    Can you explain me where is the bug in my code?

    Solved by this function...

    function wpdocs_custom_categories_terms_links() {
	// Get post by post ID.
	if ( ! $post = get_post() ) {
		return '';
	}

	// Get post type by post.
	$post_type = $post->post_type;

	// Get post type taxonomies.
	$taxonomies = get_object_taxonomies( $post_type, 'livre' );

	$out = array();

	foreach ( $taxonomies as $taxonomy_slug => $taxonomy ){

		// Get the terms related to post.
		$taxonomy = 'categorie';
		$terms = get_the_terms( $post->ID, $taxonomy_slug );

		if ( ! empty( $terms ) ) {
			$out[] = "<ul>";
			foreach ( $terms as $term ) {
				$out[] = sprintf( '<li class="cat"><a href="%1$s">%2$s</a></li>',
					esc_url( get_term_link( $term->slug, $taxonomy_slug ) ),
					esc_html( $term->name )
				);
			}
			$out[] = "\n</ul>\n";
		}
	}
	return implode( '', $out );
}

    Not solved because in the sidebar I get the list of the specific post and not the complete list of registered taxanomy terms!

    Solved with a flexible shortcode solution

    function list_terms_custom_taxonomy( $atts ) {
  
// Inside the function we extract custom taxonomy parameter of our shortcode
  
    extract( shortcode_atts( array(
        'custom_taxonomy' => '',
   ), $atts ) );
  
// arguments for function wp_list_categories
$args = array( 
'taxonomy' => $custom_taxonomy,
'title_li' => ''
);
  
if  ($custom_taxonomy = 'categorie') {
	$widget_title = 'Catégories';
	}
else if 
    ($custom_taxonomy = 'collection') {
	$widget_title = 'Collections';
    }
    
// We wrap it in unordered list 

echo '<h2 class="widget-title">' .$widget_title. '</h2><ul class="cat-list">'; 
echo wp_list_categories($args);
echo '</ul>';
}
  
// Add a shortcode that executes our function
add_shortcode( 'ct_terms', 'list_terms_custom_taxonomy' );
  
//Allow Text widgets to execute shortcodes
  
add_filter('widget_text', 'do_shortcode');
