I am creating an E-Paper kind of functionality in WordPress where the user will have to select a date from the date picker and the corresponding attachment will open. I looked all around but didn't find any suitable plugin or code.
Now, I am aware that the name or some metadata needs to match the date so that it is fetched easily. I just want to know the backend of this process. How should I go about saving the date from date picker and fetch the corresponding attachment (preferably PDF) ?
This type of functionality is used in almost all of publication sites and I want to know if it can be implemented in WordPress.
