Question

WordPress

Installed the Advanced Custom Fields plugin on WP.
Created a new field for creating/editing categories.

Anyway, what a task. I need to create a field when creating/editing a category. A field with another heading H1. If this field is empty, then the standard title is used, and if the new field is filled with data, then the category title = data of the new field.
I can't display the field values ​​in any way, I use the following function:

<?php 
     the_field('h1_caption', $term); 
?>

headings are used get_field
and here is the whole code:

<?php $cat_page_title = get_field('h1_caption', "category_".get_query_var('cat'));
      if (!empty($cat_page_title)) {
           echo $cat_page_title;
            } else 
          {                                                                    
          single_cat_title();
            }
                ?>
