View クラス

The View class acts as an object wrapper for HTML pages with embedded PHP, called "views". Variables can be assigned with the view object and referenced locally within the view.

set_filename($file)

The set_filename allows you to set or change the view filename.

set($key, $value = null, $filter = null)

The set assigns a variable to a view.

Static No

パラメータ 規定値 説明
$key 必須 variable name or array of variables
$value
null
the value
$filter
null
set to true or false to encoding, defaults to main auto encoding setting
返り値 Current View object
$view = new View;
$view->set('users', $users, false);

// or set an array

$view->set(array(
	'users' => $users,
	'articles' => $articles,
), null, true);

// If you need HTML / Javascript passed you need to set the last param to false
// when output encoding is enabled.
$view->set('example', '<h1>Heading</h1>', false);

set_safe($key, $value = null)

The same as set(), except this defaults to not-encoding the variable on output.

Static No

View::set_global(array(
	'users' => $users,
	'articles' => $articles,
), null, true);

bind($key, $value = null)

Assigns a value by reference. The benefit of binding is that values can be altered without re-setting them. It is also possible to bind variables before they have values. Assigned values will be available as a variable within the view file.

Please note: these cannot be cleaned by output encoding and should thus be considered unsafe.
