Hi there,

I’m stuck with this. I’m trying to get the ACF field image ‘logo_marque’ that I used for the taxonomy ‘marques-produit’ from my CPT ‘produits’ on my front page.

I’m using this code :

					<?php 
						$logo = get_field('logo_marque');
						$args = array( 
						'post_type' => 'produits', 
						'tax_query' => array(
							array (
								'taxonomy' => 'marques-produits',
								'fields' => $logo,
							)
						),
						'posts_per_page' => -1, 
						'order' => 'DESC' );
						$loop = new WP_Query( $args );
						while ( $loop->have_posts() ) : $loop->the_post(); ?>
						<div class="product">

						<img src="<?php echo esc_url($logo['url']); ?>" alt="<?php echo esc_attr($logo['alt']); ?>" />
						</div>
						<?php endwhile; ?>
					<?php wp_reset_query(); ?>    

Thank you for your help.

Sorry, but your question and your code do not make any sense and I’m not sure where to begin. Can you give a better explanation of what you are trying to do?

I created a taxonomy ‘marques-produit’ for my CPT ‘produits’. I used ACF to add the field image ‘logo_marque’ on my taxonomy.
Now I want to display on my front page the field ‘logo_marque’ for every label like this
<img src="<?php echo esc_url($logo['url']); ?>" alt="<?php echo esc_attr($logo['alt']); ?>" />
Thank you

That really does not help?

I see a query for posts. This has a taxonomy query. This includes 'fields' => $logo,. There is not “fields” argument for a taxonomy query. There is a “field” argument, but that argument does not take the value you are attempting to use. So I can’t really tell what posts you are trying to get here?

From what I understand you are also trying to get an image file from the term here $logo = get_field('logo_marque'); Getting a value from a term requires that you know the term, or at least the term ID and supply this when getting the ACF field. https://www.advancedcustomfields.com/resources/adding-fields-taxonomy-term/

I a guessing that you want to show posts in a term and show the term images for the post. In this case your taxonomy query requires the term ID, name, or slug to search posts by. For example

'tax_query => array(
  array(
    'taxonomy' => 'marques-produits',
    'field' => 'term_id',
    'terms' => $term_id
  )
)

I finally found out the solution. I was wrong from the start. This code works for me, it can probably be optimized

<?php
	$args = array(
		'taxonomy' => 'marques-produits',
	    'orderby' => 'name',
	    'order'   => 'ASC'
	    );	
	   $cats = get_categories($args);
	   foreach($cats as $cat) {
		   
		   if ($logo = get_field('logo_marque','marques-produits_'.$cat->term_id)) {
			   $cats_keep[] = $cat;
			   }
			}
			foreach($cats_keep as $cat) {
		   
	?>
	      <a href="<?php echo get_category_link( $cat->term_id ) ?>">
	           <img src="<?php echo esc_url($logo['url']); ?>" alt="<?php echo esc_attr($logo['alt']); ?>" />
	      </a>
	<?php
	   }
	?>

Edit the right code :

					<?php $args = array(
						'taxonomy' => 'marques-produits',
					    'orderby' => 'name',
					    'order'   => 'ASC'
					    );	
					$cats = get_categories($args);
					foreach($cats as $cat) {
						$logo = get_field('logo_marque', 'marques-produits_'. $cat->term_id .'');
						echo 
						'<a href="' . get_category_link( $cat->term_id ) . '" title="' . sprintf( __( "Voir tout les produits %s" ), $cat->name ) . '">
							<img src="' . $logo['url']; ?>" alt="<?php echo $logo['alt'] . '">
						</a>';
						}
					?>
