Hi @skd
Could you please make sure that the get_field() function returned the right data? You can check it like this:
echo <pre>;
print_r(get_field('background_image'));
echo </pre>;
If that is not returning anything, then it’s possible that your code is located outside of The Loop. To fix it, you need to pass the post/page ID as the second parameter to the get_field() function like this:
get_field('custom_field_name', 99)
Where “99” is the post/page ID where the custom field is assigned. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/get_field/.
I hope this helps 🙂
