如何使用高级自定义字段在Wordpress中将特色图像添加到类别

Question

I am new to WP and ACF and I am trying to get each category to display a featured image using a custom field set up with ACF.

I have added a field group with the location rule to show the field group if taxonomy term is equal to categories. I have then added the <?php the_field( 'add_featured_image' ); ?> to single.php

The custom field is displaying in the category options, allowing me to select a featured-image, but it is not displaying when published.

I have also tried the various different ways of targeting the ID of a single category instead of all the categories as per the ACF docs such as

<?php the_field( 'add_featured_image', 'category_6' ); ?>

or

<?php the_field('add_featured_image', 6); ?>

but nothing is working.

The nearest I have got is when using

<?php the_field( 'add_featured_image', 'category_6' ); ?>

which outputs this on the screen:

I have also tried the get_field() function to no avail. I am using FoundationPress as a parent theme.

Any help would be greatly appreciated.

Answer 1

It looks to me like you have it already with <?php the_field( 'add_featured_image', 'category_6' ); ?>. It's just outputting an object from which you have to get the src. Use $url = $add_featured_image['url']; and then echo it out into your image <img src="<?php echo $url; ?>"/>. Same method then to get the alt attribute.

You'll see more here.

Hope that helps. Best of luck!
