Question

I understand that GET is typically associated with a URL where you can put in the browser and get the exact action done again, like viewing a profile for a particular person.

I am implementing MVC pattern with CI, and with a $.ajax of type:GET to the following URL:

                url         : 'index.php/con/fx1',

where con is the controller,
fx 1 is a function in the controller.

I can direct fx1 to any model and do anything, be it POST, DELETE, or just READ.

In this sense, what difference does it make whether I specify GET/POST/DELETE/PUT

Answer 1

I’m a ruby on rails developer. But the MVC pattern is common for all (including php framework). I’m described in my way.

GET    /con        #=> index  
GET    /con/1      #=> show  
GET    /con/new    #=> new  
GET    /con/1/edit #=> edit  
PUT    /con/1      #=> update  
POST   /con        #=> create  
DELETE /con/1      #=> destroy
