I am using ACF(advance custom field) and custom post type plugin to create my own custom post type.
I have successfully created custom post type with custom field. [no problem here]
Then i have display all custom posts to users(front end user) after login. [no problem here].
if front end user(after login) like particular custom post, he/she will fill-up free subscription form against particular custom post and submit it.
Now i want to display all custom posts to users but if user already subscribed for particular post then i want to show it with different color. any solution for this?
