Php + mysql + jquery implement calendar sign-in

This article mainly introduces the process and steps for implementing the calendar sign-in function in php + mysql + jquery, which has good reference value, let's take a look at the following small series. during The website development process, we often use the sign-in function to reward user points or do some other activities. The calendar sign-in was performed during the project development process, because I had no experience and had taken many detours and recorded the process and steps again.

1. calendar sign-in style:

2. this sign-in only records the number of sign-in records for this month. if you want to query the number, you can write other pages to query all sign-in records. (The functions are very troublesome, and we didn't do it in ancient times .)

3. front-end code

 
  
Sign-in record
        
  
Signed in
    
       
Sign in now
        
Signed in
