The get method retrieves one or all variables set on a view.

Static No
Parameters
Param Default Description
$key
null
variable name
$default
null
default value to return if the variable isn't set
Returns mixed
Example
// create a view and set some data
$view = new View;
$view->set(array('field1' => 'value1', 'field2' => 'value2');

// get a single value
$field1 = $view->get('field1');

// get a single value, set a default if the field does not exist
$field3 = $view->get('field3', 'value3');

// get all values
$fields = $view->get();

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

The set method assigns a variable to a view.

Static No
Parameters
Param Default Description
$key required 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
Returns Current View object
Example
$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
Parameters
Param Default Description
$key required variable name or array of variables
$value
null
the value
Returns Current View object
Example
$view = new View;
$view->set_safe('users', $users);

// or set an array

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

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

The set_global method sets a variable accessible for all views.

Static Yes
Parameters
Param Default Description
$key required 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
Returns Void
Example
View::set_global('users', $users, false);

// or set an array

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.

Static No
Parameters
Param Default Description
$key required variable name or array of variables
$value
null
the value
Returns Current View object
Example
$view = new View;
$view->bind('users', $users, false);

// or set an array

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

bind_global($key, $value = null)

The bind_global method assigns a global variable by reference accessible for all views.

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

Static Yes
Parameters
Param Default Description
$key required variable name
$value required the value
Returns Void
Example
View::bind_global('users', $users);

render($file = null)

The render method renders the view object to a string. Global and local data are merged and extracted to create local variables within the view file.

Static No
Parameters
Param Type Default Description
$file string
null
the view filename without the extension
Returns the rendered view file
Example
$html = View::forge()->render('path/to/view');

// or

$html = View::forge('path/to/view')->render();

// or

$html = View::forge()->set_filename('path/to/view')->render();
