Load ACF JS to initialize acf per ajax calls

hello guys,

having some issue to initalize “act” variable to manage acf_form AJAX submission…

loaded the JS in the file using it:

single.js

import acf from '../../../../../../plugins/advanced-custom-fields-pro/assets/js/acf-input.min';

no errors, on compile but on page load

acf-pro-input.min.js:1 Uncaught ReferenceError: acf is not defined

any hint?

acf-pro-input.min.js uses an acf global from probably a more general acf.min.js, which then also has to be imported or enqueued (but then declared as a global in eslint/wepback configuration).

ty @strarsis but no good news :frowning:

I have updated webpack.config.js according to some older post found here:

  externals: {
    jquery: 'jQuery',
    acf: 'acf',
  },

updated the act import, to a more general one:
import acf from '../../../../../../plugins/advanced-custom-fields-pro/pro/assets/js/acf-pro-input';
note this is not imported in main.js but on single.js

but error persists :frowning:

assets/js/acf-pro-input- hm, this looks like the JS file for a ACF PRO input field.

ok, tried something different, less… picky :smiley:

import acf from '../../../../../../plugins/advanced-custom-fields-pro/assets/js/acf';

this went a bit ahead but, compiled, part of js is loading, but still have some error:

Alright, I checked out the source myself (I am also an owner of ACF PRO) and found out that these script files don’t export JavaScript modules, but rather attach to a global (window) variable.
Hence webpack will not be able to use it as a module - and it doesn’t do these checks during build but rather during runtime.

Therefore you have to import it not as symbol:

require('../../../../../../plugins/advanced-custom-fields-pro/assets/js/acf');

(or import syntax)
You have to configure webpack/ESLINT to expect acf being a global (window) variable (apparently you already did).

Or you just enqueue that script from within your theme/plugin.

ty @strarsis I think I finally managed by enqueing in setup.php.

do you think I may face issues when building and deploying, since I am including from a weird path…
wp_enqueue_script('sage/acf-input.min.js', asset_path('../../../plugins/advanced-custom-fields-pro/assets/js/acf.js'), ['jquery'], null, true);

Technically this is a not an asset path (that is resolved by Sage runtime into an URL) but a plugin url.
Therefore you should use the plugins_url method to enqueue that URL directly:

wp_enqueue_script('sage/acf-input.min.js', plugins_url('advanced-custom-fields-pro/assets/js/acf.js'), ['jquery'], null, true);
