Controller

Variables

• $autoRender

Default is true

• $description
• $argv
• $data
• $layout

Default is default

• $action
• $name

Methods

• after()

Occurs after the action has been processed (and before autorendering)

• before()

Occurs before processing the desired action

• missing()

Called when a method is missing (not callable)

It's important to notice that all the controller parameters (form data, action, argv) are already set at this point

• render($action)

May be called explicitly to render an action.

Note: after an action is rendered $this->autoRender is set to false (you shouldn't need to render two actions on the same run)

• set($name, $value)

Sets $name so the view can access it.

Helper Functions

• css($file)

Inserts a link to a css file ($file is into /app/html)

• img($file)

Inserts an image tag () ($file is into /app/html)

• isAjax()

Returns true if this in an AJAX request

• js($file)

Inserts a script tag ($file is into /app/html)

• load($file, [$params])

Loads a file from APP/lib

load("mylib.php"); // loads /app/lib/mylib.php
load("somesubdir/lib.php")  // loads /app/lib/somesubdir/lib.php

If $params is set (an array of key/value pairs) all the $key variables are exported to the script, so, it is possible to load() custom components on a view, passing variables to them.

• redirect($to)

Redirects the user to another controller/action.

$to is the URL to go to, in the controller/action/parameters form

• url($to)

Returns the right url for the controller/action passed

$to is the URL to go to, in the controller/action/parameters form

For example, one might use

<form action="<?=url('/products/sell')?>" method="post">
 [...]

To post data to the sell() action in ProductsController.

• session($name, [$value])

Reads or writes to the session

$name Is the name of the variable to store, $value is the value for that variable, if empty returns the variable's value

For example

session('user', 'User Name'); // saves "User Name" to the session
[...]
$user = session('user'); // user is "User Name"
