I’m building an Update Post form. The form uses a URL parameter (?id=123`) to load field data from an existing custom post of type..
Everything works perfectly for text fields and single-value fields using: {brf_acf_field:field_name:{url_parameter:id}}, but I can’t get a checkbox field to pre-check based on an existing ACF checkbox field. My return format is Value and I’ve also tried Both (Array).
I want the checkboxes to be conditionally checked based on what’s already selected in the ACF checkbox field for that post — exactly like how text fields prefill.Has anyone successfully achieved this?
