Using ACF outside of a theme template

Hi there,

I have the following use case:

I have created an Option Page that holds several discount coupons for an e-shop. I obviously don’t want these coupons to be printed anywhere in the theme.

Every time a user inputs a coupon code, an AJAX function POSTs the code to check_coupon_handler.php. Inside this script, I would like to get all the Option Page coupons to check whether there is one that matches the user input.

To achieve this, should I query directly the WP database, or is there a way to do so through the ACF API?

Calling get_field from check_coupon_handler.php obviously results in an undefined function error. I tried requiring wp-blog-header.php as a start, but I’m not sure whether this path makes sense.

Thanks!

You should route all ajax calles through admin-ajax.php and use action hooks to run your checking. https://codex.wordpress.org/AJAX_in_Plugins
