CakePHP Controller

Now let's move further. the next part is controller. Controller has logics (some times reffered Business logic in Java). In controller you can write any logical code, such as DB queries, calculations and every thing which you can do in PHP. But remember to use cake functions to 'Make Life Simpler'. The controller should be in app/controllers directory.

You should name controller carefully. The name of controller should be ****_controller.php (replace ****) with your controller name. You should take care about controller name because when you run any page (code) of controller you have to type http://server.com/(Controller)/(Page/Function Name).

Controller class extends AppController. If you want to add some global functions for all controllers, you can write them in cake/app_controller.php. Now lets create our first controller


class UserController extends AppController {

var $name = 'Users'; //Name of controller
#var $layout = 'upload'; //Default Layout for this model
//in case you want to use different layout (I will cover Layouts in next posts)
#var $uses = array('User'); //If you want to use more then one table (Model) then add in uses array.
#var $components = array('Email'); //Components to be used in this controller (I will cover components in next posts)
function index() // Default function, when called show index page. { }
}

CakePHP: Model

o hi..I was too busy form past few days.. didn't had tm 2 update it so lets start..
BAsically cake php is a php framework, based on MVC (Model - View - Controller)architecture. Model belongs to data. it directly associated with DB. We can definecertain DB properties, primary keys, table relationships in to model. so overall model can be think as a Database Proxy.hmm I know what question is in your mind.. Why I need Model?? hmm rite?.. ok let me explainBAsically model is abstract view of database. all the complex operation on databbase cas bedone with ease by using model functions. suppose you hav 40 columns in your DB, for inserting data you need to write a long query (near abt 1000 words), but using model just use Model::save() function.. Cool..!! no.....

need more ok..Now another cool feature is data validation. suppose you want that password must be 6-15 digit longand username must not be blank. In traditional design you need to write a long code which may take 15 minuts.But here just define it in model in few seconds and u r done!! .. A lots of more features are there.. I will tell you in next posts.

Now lets create a simple model, User


/** * Constructing model for the application. This model maps 'addresses' * table in database. It receives command from controller and applies * it to database */

class User extends AppModel {
var $name = 'User'; // Name of Model, We will use this name in our controller and view to refer 'tbl_user' table.
var $useTable = 'tbl_user'; // Name of table
var $primaryKey = 'user_id'; // Primary key

// Validation criteria
var $validate = array( 'username' => array('rule' => array('between', 6, 15), 'message' => 'Username must 6 - 15 character long.'), 'password' => array('rule' => array('between', 6, 15), 'message' => 'Password must 6 - 15 character long.'), 'email' => array('rule' => array('email'), 'message' => 'Please enter valid email'), 'first_name' => array('rule' => array('between', 1, 1000), 'message' => 'Please enter first name.'), 'last_name' => array('rule' => array('between', 1, 1000), 'message' => 'Please enter last name.'), 'address_line_1' => array('rule' => array('between', 1, 1000), 'message' => 'Please enter address'), 'city' => array('rule' => array('between', 1, 1000), 'message' => 'Please enter city.'), 'country' => array('rule' => array('between', 1, 1000), 'message' => 'Please select country'), 'day_phone' => array('rule' => array('between', 1, 20), 'message' => 'Please enter valid phone number.'), 'zip' => array('rule' => array('between', 1, 7), 'message' => 'Please enter valid zip code.') );

}
