so i created a post type that will allow user to enter Basic Information such as patient id and full name. and since they’re allowed to upload pictures in the media page, i would like the user to be able to differentiate which picture belongs to which patient by entering their id in the field provided. i want this field to be linked to the one in the Basic Information page. for instance if the entered id does not exist, a warning like “The id does not exist” will be displayed.

Basic Information page kinda looks like:

i want the patient’s ID field to be linked over here

so is this possible?
