How do you setup a Category Taxonomy in a function within Functions.php ?

I have a image field added to the Posts Category taxonomy and it’s working great within the category.php template page.

However I do have a function called on other pages which I’d like to reference the same image field.

I can’t seem to pull the field due to requiring additional details to call from another page but I can’t seem to get it working.

I’ve seen many suggest

the_field('image', 'category_' . $post->ID);

or

$queried_object = get_queried_object(); 
$taxonomy = $queried_object->taxonomy;
$term_id = $queried_object->term_id;  

the_field('image', $post->ID);

Sadly neither of these are working from the functions.php function.

The end goal would be to have an if statement checking if that field exists and returning a response if it does.

function imageFound($atts){
if(get_field('image', $post->ID))
 { 
   the_field('image', $post->ID);
   } else { 
   echo 'Sorry, the image:'. $atts . ' was not found.';
 }
}

I’d make more use of $atts but I’m just simplifying it for this example.

I’m appreciative of any input regarding this.

Hi @matt-seligman

You need to pass the ID of the category where the image is located. If you add the image to a category with the ID of 1, for example, you need to use this code:

$cat_id = '1';
the_field('image', 'category_' . $cat_id);

Or:

the_field('image', 'category_1');

This page should give you more idea about it: http://www.advancedcustomfields.com/resources/get-values-from-a-taxonomy-term/.

I hope this helps.
