ACF Custom Fields

Hi there,

The element is for single posts, but you are trying to pull term meta, which won’t work, as the single post does NOT have term meta.

The term meta can only be pulled from a term archive.

Hi there,

May I know where you assigned the ACF Image field? Is it attached to Posts or to a Taxonomy (like Categories or Tags)?

But in this case, I’m passing a specific ID. How can I make this dynamic?

You can do so for archive pages, but not single posts.

As I explained before, you can not pull term meta from a single post, and a post can have multiple categories.

So no, it’s not possible to pull the term image for the post that is assigned to that term. It will require custom development.

Just to confirm, do you only assign one category per post?

Try this:

1. add class my-category-image to the image block in your single post content template.

2. add this PHP code:

function render_term_image( $block_content, $block, $instance ) {
    if ( 
        !is_admin() && 
        !empty($block['attrs']['className']) && 
        strpos($block['attrs']['className'], 'my-category-image') !== false 
    ) {
        // Get the first term of taxonomy 'category'
        $terms = get_the_terms(get_the_ID(), 'category');

        if ($terms && !is_wp_error($terms)) {
            $first_term =$terms[0]; // Get first term
            $term_id = $first_term->term_id; // Get term ID
  
            // Get the ACF image field value for this term
            $acf_term_image = get_field('logo', 'category_' . $term_id);

                if ($acf_term_image) {
               $term_image_output = '<img src="' . esc_url($acf_term_image). '">';

                    // Insert the image before the block content
                    $block_content = $term_image_output;
                
            }
        }
    }
    return $block_content;
}

add_filter('render_block', 'render_term_image', 10, 3);
