Cakephp where is app controller

Loads Components and prepares them for initialization. Uses flash. Does not work if the current debug level is higher than 0. Loads and instantiates models required by this controller. If the model is non existent, it will throw a missing database table error, as Cake generates dynamic models for the time being. Script execution is halted after the redirect.

This method should be overridden in child classes. If not it will render a scaffold error. Method MUST return true in child classes. Internally redirects one action to another.

Sets the request objects and configures a number of controller properties based on the contents of the request. The properties that get set are. Perform the various shutdown processes for this controller. This prompts the user to confirm the action before submitting the request to delete the record. This is always recommended when dealing with actions that delete records, in case of a mistake on the user's behalf.

It's not going to be long before you need to control access to certain areas of your application. In this recipe, we'll look at adding a basic authentication layer to our existing products section, with a login view to enter your credentials. For this recipe, we'll need a table for our users. Create a table named users , using the following SQL statement:. We'll then create a User. We'll also need a UsersController.

Locate the AppController. Locate the register. In the same directory, open the login. This array is used to define the validation rules applied when creating or modifying records. Here, we simply defined the username and password fields as required, not allowing an empty value and specifying some custom messages to be returned by the model if the fields fail to validate correctly.

There are plenty more validation rules such as alphaNumeric , minLength , between , date , and email. You can also create your own rules for custom validation. After setting up our validation, we also added a beforeSave method.

This is one of the callback methods available on all models, to hook into a certain point of the process. In our method, we added some logic to process the password and generated a hash value before saving it to our users table. This way, we store a representation of the password, instead of the password itself.

This is very important as you don't want anyone viewing the actual passwords in your database. This is the recommended method of referring to the model, to allow for extensions or aliasing of a model without impacting the internal logic. This controller acts as a base controller for your application, so behavior or functionality that needs to be propagated to your entire application should be added in this class.

Here, we defined the loginRedirect and logoutRedirect settings, which define the controller and action to redirect to in each case after login or after logout. Where the action is not defined, index will be assumed by default. After that, we proceeded to add some methods to our UsersController. The first of these is the beforeFilter method.

This is one of the callback methods available on all controllers, which include beforeFilter , afterFilter , beforeRender , and beforeRedirect. Here, we first called parent::beforeFilter to make sure that we included any logic that has been defined by AppController. We then called the allow method on the Auth component to allow access to the methods in the controller. Here, you could also pass some method names to only allow certain action, or also use the deny method to explicitly deny some actions and require login.

After that, we added a register method, using the same logic to create a record as we did in the ProductsController from a previous recipe, in order to allow the creation of new users. Here, we've only used a simple example, without contemplating any postregistration checks, such as a token via e-mail for confirmation. We also included both the login and logout methods, which use the API exposed by the Auth component to process the user login.

As we're following convention by creating a users table with the username and password fields, we take advantage of the framework's ability to configure most of the sign-in process for us.

In our login action, we first called the login method on the Auth component, which internally checks the data passed in the request.

If this is successful, we redirect the user using the redirect method from the Auth component, which takes the target we previously defined in the loginRedirect setting. If the process were to fail, we stay in the same action but use the setFlash method from the Session component to display a message to the user that the sign in was unsuccessful.

The logout method is even easier, simply calling the logout method on the Auth component and redirecting the user to that location. Here, as with the login method, we use the logoutRedirect setting we had previously defined. As you can see so far, authentication in CakePHP is really a piece of cake. We then went on to create our views to register a new user and sign in.

In our first view, register. We then used the inputs methods to render the required inputs and finally called end , passing our text for the submit button. In our login. This renders a location to collect the flash messages sent from the Auth component, such as the message we display when the login fails. The use of the auth value allows you to easily manage the messages being collected, in case you'd like them to be displayed differently or in different locations of your view.

Chapter 5 , Using Authentication. One of the greatest benefits of using CakePHP is its extensibility. Using plugins, you can extend and enhance the core functionality, which provides you with even more cake than you bargained for! In this recipe, we'll look at loading a plugin using DebugKit, the official development and debugging tool for the framework, as an example. X Installation. In that array, You need to change localhost on demand , user , password and database.

DB issue should gone and show Green Tick at left side. Download cakephp Remarks This section provides an overview of what cakephp The controller takes the request from the user through dispatchers like action, which makes sure the right models and views are called. So, it acts as a bridge between models and views.

The AppController class is the superclass of all controllers, which extends the main Controller class. All the method of the controller, which is predefined in the controller class, is known as Actions.

It is responsible for handling the request and sending an appropriate response to the browser. It represents output in the form of visuals that can be provided to create a responsive browser for the user.
