Running Any Codes Before Action on Controller Execute on Yii

You can execute any codes before action method on controller run with beforeAction() method. For example, you want to make every action method are JSON type on content. So, you can add method like this on your controller:

        protected function beforeAction($action){
            header('Content-Type: application/json');
            return parent::beforeAction($action);
        }

its will be effected to all actionAny() to JSON as type of content

Simple jQuery Ajax Post Sending

Sending POST data to server using jQuery is very simple. I assumed that you sending POST data when the DIV with id:#sendme is clicked. So, you can use codes like this:

$("#sendme").click(function(){

 $.post("URL POST",

    {

        param1: "value1",

        param2: "value2"

    },

    function(data, status){

    });

});

- URL POST can be replaced with your URL post

- param1 and param2 are name of post data

- value1 and value2 are value of param that will be sent to URL POST

Understanding Java Looping using FOR

FOR function used for do some similar command with certain limited count number. The basic structure of FOR is like this:

for(int i=0;i<=10;i++){

     System.out.print(i);

}

explanation:

int i = 0 is set up the first number

i<= 10 is a limited number. Symbol <= means i value smaller or same than 10

i++ is for increment first number. If you want to decrement function, you can write as i--
