Problem with Footnotes plugin and ACF Pro

hi.

There were several threads but it hasn’t been solved for me.
I’m using this plugin: https://wordpress.org/plugins/footnotes/

I have several ACF fields in my post, where i put footnotes. I put this function into my child theme functions.php file:

function acf_apply_content_filter_for_api($value, $post_id, $field){
     return str_replace( ']]>', ']]>', apply_filters( 'the_content', $value) );
}
function add_content_filter_ACF(){
   if(!is_admin()){
      remove_all_filters('acf/format_value/type=wysiwyg');
      add_filter('acf/format_value/type=wysiwyg', 'acf_apply_content_filter_for_api', 10, 3);
   }
}
add_action('init', 'add_content_filter_ACF');

It starts to work(let’s say) but the problem is the footnotes summary appears after every WYSIWYG field, and also it doesnt work fully properly.. I want it to only appear after all the contents of the post and summarize footnotes from all fields.

somebody proposed a solution but i dont understand it and it doesnt work for me:
https://support.advancedcustomfields.com/forums/topic/help-with-easy-footnotes-plugin-acf-wysiwyg/

edit: if it’s unclear ill rephrase what im looking for:
Is there a way to select all the output of ACF and apply a filter to it, treating it as a single field? or just select all the content of a wordpress post?

I’m an amateur when it comes to core understanding of WP and PHP and it’s my second day of using ACF 😉

thank you!

I fixed it. Fixes same problem with Table of content.

I just add the fields i want to be parsed by the plugins to wordpress’ the_content() in my template.

<?php 			
add_filter('the_content','prepend_this');
function prepend_this($content)
{
    $content = get_field("some_field");
    return $content;
}
?>
<?php the_content(); ?>

my site uses only ACF fields for content, so the_content() is always empty. Your results may vary.

If something’s not clear, ask away.
