Sort custom posts by date from two diffrent custom field

  • Hey I have problem with sort my gallery custom posts.

    I created my CPT Gallery and my CPT Event.

    Gallery have ACF field ‘date’ and field named ‘related_event’. Event have ACF field ‘start_event_date’.

    Some galleries have relationship with Events but some have not.

    If gallery have ralationship with Event date of gallery is date of Event (custom field – ‘start_event_date’) but if gallery have not relation value of date is value of own custom field ‘date’.

    I dont’t have idea how can I connect value of dates and sort by them.

    Please give me any advice or corrcet solution my issue.

  • You cannot posts by the date field in a different post, you can only order posts by fields that belong to those posts.

    You will need to create an acf/save_post filter for your gallery post type. In this filter you will need to see if there is a related event. If there is then you get the date from the related event and update the date field for the gallery. Then you order by this one date field.
