Custom Taxonomy Archive Issues

Hello, I am having trouble getting the field values to display on my taxonomy archive (archive-mytax.php). The archive shows a list of my tax terms using this.

<?php

$terms = get_terms( 'mytax' , 'hide_empty=false' );

echo '<div class="row">';

foreach ( $terms as $term ) {

    // The $term is an object, so we don't need to specify the $taxonomy.
    $term_link = get_term_link( $term );

    // If there was an error, continue to the next term.
    if ( is_wp_error( $term_link ) ) {
        continue;
    }

    // We successfully got a link. Print it out.
    echo '<div class="col-lg-3"><a href="' . esc_url( $term_link ) . '">' . $term->name . '</a></div>';
}

echo '</div>';

?>

I have set up custom fields for my taxonomy terms. Am having trouble using the suggested codes (any of them) to return the field values.

Are you using something that looks like this:

$id = $term->slug.'_'.$term->term_id;
get_field('custom_field_name', $id);

As shown on http://www.advancedcustomfields.com/resources/functions/get_field/ the id needed to get your custom field is a combo of the term slug and underscore and the term id.

Hi I have tried this a few ways, but I don’t think I’m doing it correct. :S I’m not a PHP guru. Can you help me know where exactly my values need to go in that code? Assume my taxonomy is “Research”. Also, I really want to avoid specifying an actual term ID. I would like the fields to be pulled automatically for every term displaying on my archive page.

The term_id is drawn from the term in your loop of the results from get_terms. WP does not automatically generate the id that you need. These are special IDs that ACF needs to locate your data.

foreach ( $terms as $term ) {

    // The $term is an object, so we don't need to specify the $taxonomy.
    $term_link = get_term_link( $term );

    // If there was an error, continue to the next term.
    if ( is_wp_error( $term_link ) ) {
        continue;
    }

    // We successfully got a link. Print it out.
    echo '<div class="col-lg-3"><a href="' . esc_url( $term_link ) . '">' . $term->name . '</a></div>';

    // show custom fields for the term
    // this id will be generated for each term
    $id = $term->slug.'_'.$term->term_id;
    the_field('my_first_custom_field', $id);
    the_field('my_second_custom_field', $id);
}

Do I have to change anything on this line?

$id = $term->slug.'_'.$term->term_id;

you shouldn’t need to as long as it’s inside your loop

foreach ( $terms as $term ) {
  $id = $term->slug.'_'.$term->term_id;
}

Hm, well I couldn’t make that work, but found another solution online that seems to do what I need.

<?php

        $libargs=array(  
            'hide_empty'        => 0,  
            'parent'        => 0,  
            'taxonomy'      => 'MYTAXONOMYNAME');  
			

            $libcats=get_categories($libargs);  

            foreach($libcats as $lc){ 
			echo '<div class="col-lg-3">';
                $termlink = get_term_link( $lc->slug, 'MYTAXONOMYNAME' ); 

        ?>
           <p class="text-center"> <a href="<?php echo $termlink; ?>">
 <img class="img-responsive img-thumbnail" src="<?php the_field('taximage', 'MYTAXONOMYNAME_'.$lc->term_id); ?>" />
   <br />
            <?php echo $lc->name; ?></a></p>
                     <?php the_field('basictext', 'MYTAXONOMYNAME_'.$lc->term_id); ?>
                     
                      
               <?php   echo '</div>'; }?>

Not real sure why it works over the other method, but it does.

okay, sorry, I didn’t do a test and after looking at the code I realize my mistake.

The first part where I put “$term->term_slug” should have been the “Taxonomy Slug” for your taxonomy.
'my-tax_'.$term->term_id
which is, of course, what that code you posted is doing. My brain is just turning to mush 😛

Hi Hube! Well thanks for letting me know why it wasn’t working. I’m somewhat glad to know it wasn’t just me. I’m still a learning. 🙂 Thanks again!
