WordPress/ACF: get_category(); 对于父类别

Question

I am using an ACF Wysiwyg Editor field in order to be able to write some extra text for my category pages. I am echoing the text using category.php

At first I thought I could just echo out get_field but found out that I need to pass in the category. Therefore I've used get_the_category(). But for some reason code only works for child categories:

example.com/category/parent/child/ <- works example.com/category/parent/ <- doesn't work

I've also tried with wp_get_post_categories(); but no luck. What am I missing ??

<?php

$category = get_the_category();

$extra_text = get_field('ekstra_tekstfelt', $category[0] );
?>

<p> <?php echo $extra_text ?></p>

I've tried print_r($category) where both child and parent category gave me an array:

Child category

Array ( [0] => WP_Term Object ( [term_id] => 27 [name] => Tilbehør [slug] => tilbehor [term_group] => 0 [term_taxonomy_id] => 27 [taxonomy] => category [description] => [parent] => 1 [count] => 31 [filter] => raw [cat_ID] => 27 [category_count] => 31 [category_description] => [cat_name] => Tilbehør [category_nicename] => tilbehor [category_parent] => 1 ) )

Parent category

Array ( [0] => WP_Term Object ( [term_id] => 46 [name] => Bagværk [slug] => bagvaerk [term_group] => 0 [term_taxonomy_id] => 46 [taxonomy] => category [description] => [parent] => 1 [count] => 16 [filter] => raw [cat_ID] => 46 [category_count] => 16 [category_description] => [cat_name] => Bagværk [category_nicename] => bagvaerk [category_parent] => 1 ) [1] => WP_Term Object ( [term_id] => 16 [name] => Dessert [slug] => dessert [term_group] => 0 [term_taxonomy_id] => 16 [taxonomy] => category [description] => [parent] => 1 [count] => 22 [filter] => raw [cat_ID] => 16 [category_count] => 22 [category_description] => [cat_name] => Dessert [category_nicename] => dessert [category_parent] => 1 ) )

Going through your code, it seems to be fine but need to check whether we are getting values for every variable or not, whether the acf fields are empty or not?

Below is the example from official site of ACF. In your code, you can make sure you are getting proper object of second argument you are passing.

 // get the current taxonomy term
 $term = get_queried_object(); // or other way where you get the category term object
 // example
 $image = get_field('image', $term);
 $color = get_field('color', $term);
 echo $color;
 echo $image;
