I want to make 2 different quizzes, a monthly quiz and a daily quiz, so the daily quiz is shown every day to the logged in user and the monthly quiz every 30 days.

Any ideas how to implement this with html / javascript? I think I need a counter variable to proof counter < 7. How can I count the days between last quiz and now?

I asked somewhat a similar question a while ago and this is one of the responses I got. My question was more to with how to make use a wait X amount of days before they could leave a review on my ecommerce store. Hopefully this will guide you in the right direction.

As I understand your use case, you need a persistent storage method to remember how many days have passed since a particular action/thing. There are, in general, 4 methods of persistent storage:

1. Cookies:

  • Storage: Client Side
  • Specific: Unique to user machine and domain
  • Persistence Time: Can last forever unless the user specifically deletes the cookie
  • Common Use Cases: Saved preferences

2. Session

  • Storage: Server Side (depends on driver)
  • Specific: Specific to user (but depends on driver)
  • Persistence Time: Usually expires in a couple of hours, but can be extended
  • Common Use Cases: Persistence layer from one request to another (like shopping cart, popup notifications after action triggers)

3. Caching

  • Storage: Server Side
  • Specific: Generally application specific (but can be user specific)
  • Persistence Time: Generally an hour to a couple of days
  • Common Use Cases: Application specific storage use cases (e.g. total number of hits, most popular pages, database query caching, view caching)

4. Database

  • Storage: Server Side
  • Specific: Can be user or app specific
  • Persistence Time: Forever until deleted
  • Common Use Cases: Longer term data persistence layer (e.g. user details)
