In category, select other categories and return their name, an image and link?

Hi

Is there a way for my client to set up a category with a list of all the others so they can select similar categories.

On articles of a given category I would like to list those selected items in a sidebar, it would display the category name, an image assigned to that category in ACF and a link to the category.

I’ve been searching but I can’t find relevant documentation. If someone could point me in the right direction that would be superb.

I’m using pro and I’m teaching myself ACF and PHP as I go.

Thanks in advance.

I’ve actually stunned myself and somehow figured this out. See my messy code below.

Each category has an image assigned in ACF (prod_image). I created a group “Taxonomy is equal to Category”, field type “Taxonomy” with radio buttons outputting a term ID.

<?php
$the_cat = get_the_category();
$the_cat = get_the_category( $id );
$category_name = $the_cat[0]->cat_name;
$category_link = get_category_link( $the_cat[0]->cat_ID );
?>

<!--Related Games-->
<?php if( get_field('show_related_games', 'term_'. $cat_id) ): ?>
<div>

    <!--Section Title-->
    <h3>
        <?php the_field( 'related_games_title', 'term_'. $cat_id ); ?>
    </h3>

    <!--Repeat field-->
    <?php if( have_rows('related_game', 'term_'. $cat_id) ): while ( have_rows('related_game', 'term_'. $cat_id) ) : the_row(); ?>
    <!--Product-->
    <div>
        <?php $term_id = get_sub_field('related_link');
                                    if( $term_id):
                                        $term_name = get_cat_name( $term_id ) ;
                                        $term_url = get_category_link( $term_id );
                                        $prod_image = get_field( 'prod_image', 'term_'. $term_id);?>
        <a href="<?php echo $term_url; ?>" class="relatedprod" target="_blank">

            <!--Packshot-->
            <?php if ( $prod_image ) { ?>
                <img src="<?php echo $prod_image['url']; ?>" alt="<?php echo $prod_image['alt']; ?>" />
            <?php } ?>

            <!--Product Info-->
            <div class="prodinfo">
                <div class="gamename">
                    <?php echo $term_name; ?>
                </div>
                <div class="smallgreencta">
                    <?php the_sub_field('cta_text'); ?>
                </div>
            </div>
        </a>
        <?php endif; ?>
    </div>
    <?php endwhile; else :
    // no rows found
    endif; ?>

</div>
<?php endif;?>
