APPLICATION CONTROLLER[editar]
Métodos de la Clase ApplicationController[editar]
This class has several useful methods to work with controllers.
ApplicationController Class Methods[editar]
This class has several useful methods to work with controllers.
render($view)[editar]
Shows a view belonging to the same controller.
Example:
<?php class ProductsController extends ApplicationController { function index(){ $this->render('list'); } } //end of class ?>
In this case, the view views/products/list.phtml will be rendered.
redirect($url, $seconds=0.5)[editar]
Wait $seconds, then redirect to another url.
Example:
<?php class ProductsController extends ApplicationController { function index(){ $this->redirect('tickets/new', 2); } } ?>
The browser will go to tickets/new 2 seconds later
post($value)[editar]
Object oriented access to $_POST[$value].
get($value)[editar]
Object oriented access to $_GET[$value].
request($value)[editar]
Object oriented access to $_REQUEST[$value].
render_partial($name)[editar]
Render the partial view belonging to the same controller. Example:
Example:
<?php class ProductsController extends ApplicationController { function index(){ $this->render_partial('show_menu'); }//end of method }//end of class ?>
The above example will output the partial view views/products/_show_menu.phtml
route_to([params: value])[editar]
Redirect from a controller to another or from an action to another. The parameters are:
- controller: Destination controller to do the redirect.
- action: Destination action to do the redirect
- id: route id
Example:
return $this->route_to("controller: clients", "action: query", "id:1");
The redirects are internal ones, meaning the users will not realize they are been redirected.
redirect($url_controlador)[editar]
Do a redirect to another controller or action using HTTP. This is a "real" redirect to another HTML page. The URL page changes in the user browser.
Example:
$this->redirect("/products/query");
cache_layout($minutes)[editar]
Cache the view views/layout/ belonging to the controller for $minutes.
not_found($controller, $action) =[editar]
Optional method. It could be defined in any controller. If not_found method is defined then it will be called every time some action is not found. This is useful to process this kind of errors.
Example
<?php class TestController extends ApplicationController { function index(){ $this->render_text("This is the index"); } function not_found($controller, $action){ Flash::error("I am sorry. The action $action is not defined, redirecting to index..."); return $this->route_to('action: index'); } } ?>
Note: There is in the 0.5 version a default view views/not_found.phtml with the same behaviour for the whole application. If not_found method is not implemented in a controller, the views/not_found.phtml actionn will be executed. Using this default action speeds up the development.
set_response($type)[editar]
Set the controlled generated answer type.
If $type is "view" then kumbiaPHP will output the view only without layout, template or any html header. This is useful to generate AJAX or PDF output.
Another $type value is "XML".
Example
<?php class TestController extends ApplicationController { function accion_ajax(){ $this->set_response("view"); } } ?>
is_alnum($value)[editar]
Checks if $value is alphanumeric. Useful for user input validation.
<?php class TestController extends ApplicationController { function add(){ $price = $this->request("price"); if($this->is_alnum($price)==false){ Flash::error("price has not a valid value"); return; } /* ..*/ } } ?>
load_record($record, $args...)[editar]
Load the fields in a ActiveRecord record like controller attributes. The parameters are:
- $record, ActiveRecord or a string ActiveRecord record to load. If the parameter is a string then it must be a name of a model.
- $args, optional parameters:
- field: comma separated field names to load
- except: comma separated field name to NOT load.
- suffix: suffix for the attribute in the controller
- preffix: preffix for the attribute in the controller
Examples Example 1
$user = $this->User->find(1); $this->load_record($user);
Example 2
$user = $this->User->find(1); $this->load_record($user, 'except: id, sex');
Example 3
$user = $this->User->find(1); $this->load_record($user, 'field: name, lastname');
Example 4
$user = $this->User->find(1); $this->load_record($user, 'preffix: c_');
Example 5
$this->load_record('User');
Example 6 $this->load_record('User', 'field: name,lastname');
== is_numeric($value) ==
Checks if $value is numeric. This method is useful for user input validation.
Example
<?php class TestController extends ApplicationController { function add(){ $price = $this->request("price"); if($this->is_numeric($price)==false){ Flash::error(“Ivalid price input”); return; } /* ..*/ } } ?>
