Get term ACF Image Field

  • I have code to load the last 6 terms and only use terms without children so I get the months and not the years which are both part of the same Taxonomy as terms. I can already load the titles as links, but I am trying to load the attached ACF image field which I am failing to do.

    I use $summaryimage = get_field('summary_preview_image'); inside this block.php file to then use it for wp_get_attachment_image( $summaryimage, $size ). But it seems that the variable is not loading anything and so my term image is not being loaded. Question is why this is not working inside wp-content/themes/theme/blocks/spotlight/block.php I am guessing cause I perhaps need to indicate more in the get_field request to grab the image from the specific group which is used to attach a custom filed to the term.. But how?

    $args = array( 'hide_empty=0', 
                    'childless'     => 1, 
                    'number'        => 6,
                    'orderby'       => 'ID', 
                    'order'         => 'ASC'
                    ); 
    
    $terms = get_terms( 'molecules_of_the_month', $args );
    if ( ! empty( $terms )   ) :
        $summaryimage = get_field('summary_preview_image');
        print_r($summaryimage);
        $size = 'full'; // (thumbnail, medium, large, full or custom size)
        $count = count( $terms );
        $i = 0;
        $term_list = '<p class="molecule-of-the-month">';

  • Did try

    $terms = get_terms( 'molecules_of_the_month', $args );
    if ( ! empty( $terms )   ) :
        $termid = get_queried_object()->term_id;
        print_r($termid);
        $summaryimage = get_field('summary_preview_image', $termid);
        // print_r($summaryimage);
        $size = 'full'; // (thumbnail, medium, large, full or custom size)
        $count = count( $terms );

    but also do not get the term id . Perhaps I need to do another query on top, not sure yet…

  • Would the get field not need the taxonomy name? As per the docs

    For example:
    $summaryimage = get_field('summary_preview_image', 'tax_name_'.$termid);

    Assuming the image is assigned to the taxonomy.

  • Thanks for the feedback @jarvis . When I Use this updated code:

    $terms = get_terms( 'molecules_of_the_month', $args );
    if ( ! empty( $terms )   ) :
        $termid = get_queried_object()->term_id;
        var_dump($termid);
        $summaryimage = get_field('summary_preview_image', 'tax_name_'.$termid);
        // print_r($summaryimage);
        $size = 'full'; // (thumbnail, medium, large, full or custom size)
        $count = count( $terms );
        $i = 0;
        $term_list = '<p class="molecule-of-the-month">';
        ?>

    does however not work … yet either. The var_dump shows me string(0) “”. So besides me not specifying the taxonomy (month here though acf group with field preview_image is attached to term month and year) something else is still needed I think.

  • Try changing tax_name to your actual taxonomy, does that work?

  • I tried

    <?php $args = array( 'hide_empty=0', 
                    'childless'     => 1, 
                    'number'        => 6,
                    'orderby'       => 'ID', 
                    'order'         => 'ASC'
                    ); 
    
    $terms = get_terms( 'molecules_of_the_month', $args );
    if ( ! empty( $terms )   ) :
        // $termid = get_queried_object()->term_id;
        // var_dump($termid);
        $summaryimage = get_field('summary_preview_image', 'tax_name_', 'molecules_of_the_month');
        // print_r($summaryimage);
        $size = 'full'; // (thumbnail, medium, large, full or custom size)
        $count = count( $terms );
        $i = 0;
        $term_list = '<p class="molecule-of-the-month">';
        ?>
        <div id="<?php echo esc_attr($id); ?>" class="<?php echo esc_attr($className); ?>">

                                }
                            }
                            echo $term_list;

            </div>
        </div>
    <?php endif;?>

    and the var_dump for summary_image is NULL. Do not get it. And the ACF field is there:

    Try that on its own, if it works, integrate it into your code

  • @jarvis I used your code with foreach loops:

    <div id="<?php echo esc_attr($id); ?>" class="<?php echo esc_attr($className); ?>">
            <div class="slider mobile-slider splide" data-splide='{ "type" : "loop", "perPage": "3", "arrows": 0, "breakpoints": { "99999": { "destroy": 1 }, "767": { "perPage": "1" } } }'>
                <div class="splide__track">
                    <ul class="post-grid splide__list">
                        <?php 
                        if( $molecules_of_the_month = get_terms( array( 'taxonomy' => 'molecules_of_the_month' ) ) ) :
                            foreach( $molecules_of_the_month as $month ) : 
                                $summaryimage  = get_field('summary_preview_image', 'term_' .$month->term_id  );
                                $size = 'full'; // (thumbnail, medium, large, full or custom size)
                                print_r($summaryimage);
                                // $molecules_of_the_month .= '<a href="' . esc_url( get_term_link( $month ) ) . '" alt="' . esc_attr( sprintf( __( 'View all post filed under %s', 'theme' ), 
                                // $month->name ) ) . '">' . $month->name . '</a><figure class="post-featured-image">' . 
                                // wp_get_attachment_image( $summaryimage, $size ) . '</figure>';
                            endforeach;
                        endif; ?>

                </div>
            </div>
        </div>

    and I know get 328235043514 or this using var_dump

    NULL int(3282) bool(false) bool(false) bool(false) int(3504) int(3514) bool(false) NULL bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false) bool(false)

    so I am getting something now. So I guess I needed to load the image in the foreach loop. But I also see you used:

    <?php $summaryimage = get_field('summary_preview_image', 'term_' .$month->term_id );?>

    with term_ .$month->term_id which I am clearly not familiar enough with. Besides understanding this better I also need to load the image url so guess I do not want ID numbers only. How would I do that?

    I have the summaryimage loading ids but not in use yet as I need image url. This so I can load the image, title and short description and link it all.

    I also can still load term links using this loop and an echo so that is fine. But need to work out loading image first.

    Furthermore I need to include the $args I had before. Not sure how with current setup. Doing some trials still.

  • Wait, echo wp_get_attachment_image( $summaryimage, $size ); does seem to try to load images now like:

    <img width="1191" height="1684" src="https://site.test/wp-content/uploads/2021/10/2021-MOTM-Aug.png" class="attachment-full size-full" alt="" loading="lazy" srcset="https://site.test/wp-content/uploads/2021/10/2021-MOTM-Aug.png 1191w, https://site.test/wp-content/uploads/2021/10/2021-MOTM-Aug-212x300.png 212w, https://site.test/wp-content/uploads/2021/10/2021-MOTM-Aug-724x1024.png 724w, https://site.test/wp-content/uploads/2021/10/2021-MOTM-Aug-768x1086.png 768w, https://site.test/wp-content/uploads/2021/10/2021-MOTM-Aug-1086x1536.png 1086w" sizes="(max-width: 1191px) 100vw, 1191px">

    so I am making progress and thanks to you @jarvis . Thanks a lot so far.

    Now I just need to add proper html, include $args, load part of text or excerpt and then I will be done.

  • Seems that I need to use WP_Query to loads arguments

    $args = array( 'hide_empty=0', 
                    'childless'     => 1, 
                    'number'        => 6,
                    'orderby'       => 'ID', 
                    'order'         => 'ASC'
                    ); 

    if I want to use these in get_terms. See https://developer.wordpress.org/reference/classes/wp_term_query/get_terms/#user-contributed-notes

    example:

    <ul>
    <?php 
    $args = array(
        'taxonomy'               => 'category',
        'orderby'                => 'name',
        'order'                  => 'ASC',
        'hide_empty'             => false,
    );
    $the_query = new WP_Term_Query($args);
    foreach($the_query->get_terms() as $term){ 
    ?>
        <li><?php echo $term->name." (".$term->count.")"; ?></li>
    <?php
    }
    ?>
    </ul>

    Will look into that.

  • Had to use

    <?php 
    $args = array( 'hide_empty=0', 
            'taxonomy'      => 'molecules_of_the_month',
            'childless'     => 1, 
            'number'        => 6,
            'orderby'       => 'ID', 
            'order'         => 'ASC'
            ); 
    $the_query = new WP_Term_Query($args);
    foreach($the_query->get_terms() as $term) :
    // foreach( $molecules_of_the_month as $month ) : ?>
        <!-- Post Content goes here -->
        <li class="post-grid-post splide__slide">
            <?php
            $summaryimage  = get_field('summary_preview_image', 'term_' .$term->term_id  ); // field, id and format value

    to make it work. Well, that seems to make most of what I want do. Need to limit description, tweak html to work on mobile. But will work well soon.
