Calls a method on this object with the given parameters. Convenience method to write a message to CakeLog. See CakeLog::write for more information on writing to logs. Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. You should use URL formats that are compatible with Router::reverse. String or array-based url. Class Navigation. Class AppController This is a placeholder class.
Returns mixed true if models found and instance created. Deprecated Use CakeResponse::disableCache. Deprecated Use CakeResponse::header. Deprecated Use CakeResponse::httpCodes ;. If you need CakePHP in a command-line script or some other outside use, constructClasses may come in handy.
Returns the referring URL for the current request. So, instead of doing this:. This is different than view caching, covered in a later chapter. Last-Modified: [current datetime] GMT. Cache-Control: no-store, no-cache, must-revalidate. Pragma: no-cache. Use this method to turn a set of POSTed model data from HtmlHelper-compatible inputs into a set of find conditions for a model. This function offers a quick shortcut on building search logic.
For example, an administrative user may want to be able to search orders in order to know which items need to be shipped. Then a controller action can use the data posted from that form to craft find conditions:.
This method is used for paginating results fetched by your models. You can specify page sizes, model find conditions and more. See the pagination section for more details on how to use paginate. If used without caching requestAction can lead to poor performance. It is rarely appropriate to use in a controller or model. First we need to create a controller function that will return the data. So checking that you can either return the required data else set it a view variable like you normally would.
This helps keep things DRY. Written in this way, whenever the element is rendered, a request will be made to the controller to get the data, the data will be processed, and returned. By modifying the call to element to look like this:.
The requestAction call will not be made while the cached element view file exists and is valid. This allows the requestAction call to bypass the usage of Router::url which can increase performance.
The url based arrays are the same as the ones that HtmlHelper::link uses with one difference - if you are using named or passed parameters, you must put them in a second array and wrap them with the correct key.
Controller attributes and methods created in your AppController will be available in all controllers that extend it. You can use your AppController to load components that will be used in every controller in your application. While normal object-oriented inheritance rules apply, the components and helpers used by a controller are treated specially. In these cases, AppController property values are merged with child controller class arrays.
The values in the child class will always override those in AppController. The request data is encapsulated in a request object. CakePHP uses conventions to automate this process and remove some boilerplate code you would otherwise need to write. By convention, CakePHP renders a view with an inflected version of the action name.
Returning to our online bakery example, our RecipesController might contain the view , share , and search actions.
The conventional view file name is the lowercased and underscored version of the action name. Controller actions generally use Controller::set to create a context that View uses to render the view layer. Instead, once a controller action has completed, CakePHP will handle rendering and delivering the View.
Controllers interact with views in a number of ways. First, they are able to pass data to the views, using Controller::set. You can also decide which view class to use, and which view file should be rendered from the controller. The Controller::set method is the main way to send data from your controller to your view.
It seems to me it would be better to implement that function in a place to make it more convenient to re-use, e. Add a comment. Active Oldest Votes. This is just plain wrong: Output formatting code in a controller instead of a helper TimeHelper::format doesnt work? Business logic in the component instead of the model layer getWeeklyData You're not following any coding standard conventions There is even markup in the component method You defeat the idea of separating presentation from business logic You have seriously absolutely no idea what you're doing in terms of design patterns or how CakePHP works.

It would be better to help if you edit your question and share your code as well. SuneelKumar — Sumit Parakh. This code is horribly wrong in so many aspects
