Get ACF options field in PHP acting as CSS

Question

I am combining all of my css files into one file via PHP using

header('Content-type: text/css');

Within that processed PHP file, I want to get a field from an options page within Advanced Custom Fields.

the_field('field_name', 'option');

Even though I can successfully call the field in the section in 'header.php', I can't get it within the PHP file processing my css. Is there a way to do this?

I'm not sure what exactly your setup is or where this file is but ACF saves its values as post meta. So you could simply use WP's get_post_meta() if ACF isn't available.

For Example:

get_post_meta( get_the_ID(), 'field_name', true );

You can also have a look at this article, it talks about using get_post_meta vs ACF functions.
