Add Like in Joomla?

Question

Joomla

How to implement the task, there is a module, it contains div blocks with a photo, you need to add a like function under each block, such as a registered user in Joomla can put a like.
Thanks in advance!

Answer 1

Before displaying the module, you execute an SQL query in which two actions are performed:
1. Counting the number of likes from all users
2. Determine whether the user liked it or not... (it depends on how the likes button will look)
2.1. If the user likes it, then we change the picture itself and when you click on it, another SQL query will be executed that will remove the like !!!
2.2. If the user did not like it, then we display the full number of likes and assign another SQL query that will add one more like...
Yes, in my opinion, that's all you need... If there are difficulties , write , I'll help...
