public function __clone()
{
$this->_events = [];
$this->_eventWildcards = [];
$this->_behaviors = null;
}
Defined in: yii\base\BaseObject::__construct()
Constructor.
The default implementation does two things:
- Initializes the object with the given configuration
$config
. - Call init().
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$config
here. - call the parent implementation at the end of the constructor.
public void __construct ( $config = [] ) | ||

}
Defined in: yii\base\Component::__get()
Returns the value of a component property.
This method will check in the following order and act accordingly:
- a property defined by a getter: return the getter result
- a property of a behavior: return the behavior property value
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $value = $component->property;
.

}
}
$this->dynamicPlaceholders[$placeholder] = $statements;
Defined in: yii\base\View::afterRender()
This method is invoked right after renderFile() renders a view file.

$viewFile | string |
The view file being rendered. |
$params | array |
The parameter array passed to the render() method. |

]);
$event->output =& $output;
$this->trigger(self::EVENT_AFTER_RENDER, $event);
}
}
Defined in: yii\base\Component::attachBehavior()
Attaches a behavior to this component.

{
$this->ensureBehaviors();
return $this->attachBehaviorInternal($name, $behavior);
}
Defined in: yii\base\Component::attachBehaviors()
Attaches a list of behaviors to the component.

return Block::begin([
'id' => $id,
'renderInPlace' => $renderInPlace,
'view' => $this,
]);
}
Defined in: yii\base\View::beginCache()
Begins fragment caching.
This method will display cached content if it is available. If not, it will start caching and would expect an endCache() call to end the cache and save the content into cache. A typical usage of fragment caching is as follows,
if ($this->beginCache($id)) {
// ...generate content here
$this->endCache();
}
public boolean beginCache ( $id, $properties = [] ) | ||
$id | string |
A unique ID identifying the fragment to be cached. |
$properties | array |
Initial property values for yii\widgets\FragmentCache |
return | boolean |
Whether you should generate the content for caching. False if the cached version is available. |
---|
public function beginCache($id, $properties = [])
{

$this->endCache();
return false;
}
return true;
}
Defined in: yii\base\View::beginContent()
Begins the rendering of content that is to be decorated by the specified view.
This method can be used to implement nested layout. For example, a layout can be embedded in another layout file specified as '@app/views/layouts/base.php' like the following:
<?php $this->beginContent('@app/views/layouts/base.php'); ?>
//...layout content here...
<?php $this->endContent(); ?>
See also yii\widgets\ContentDecorator.
public yii\widgets\ContentDecorator beginContent ( $viewFile, $params = [] ) | ||
$viewFile | string |
The view file that will be used to decorate the content enclosed by this widget. This can be specified as either the view file path or path alias. |

return | yii\widgets\ContentDecorator |
The ContentDecorator widget instance |
---|
public function beginContent($viewFile, $params = [])

]);
}
Defined in: yii\base\View::beginPage()
Marks the beginning of a page.
public void beginPage ( ) |
public function beginPage()
{
ob_start();
ob_implicit_flush(false);
$this->trigger(self::EVENT_BEGIN_PAGE);
}
Defined in: yii\base\Component::behaviors()
Returns a list of behaviors that this component should behave as.
Child classes may override this method to specify the behaviors they want to behave as.
The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:
'behaviorName' => [
'class' => 'BehaviorClass',
'property1' => 'value1',
'property2' => 'value2',
]
Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.
Behaviors declared in this method will be attached to the component automatically (on demand).
public array behaviors ( ) | ||
return | array |
The behavior configurations. |
---|
public function behaviors()
{
return [];
}
Defined in: yii\base\Component::canGetProperty()
Returns a value indicating whether a property can be read.
A property can be read if:
- the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when
$checkVars
is true); - an attached behavior has a readable property of the given name (when
$checkBehaviors
is true).

Defined in: yii\base\Component::on()
Attaches an event handler to an event.
The event handler must be a valid PHP callback. The following are some examples:
function ($event) { ... } // anonymous function
[$object, 'handleClick'] // $object->handleClick()
['Page', 'handleClick'] // Page::handleClick()
'handleClick' // global function handleClick()
The event handler must be defined with the following signature,
function ($event)
where $event
is an yii\base\Event object which includes parameters associated with the event.
Since 2.0.14 you can specify event name as a wildcard pattern:
$component->on('event.group.*', function ($event) {
Yii::trace($event->name . ' is triggered.');
});
See also off().
public void on ( $name, $handler, $data = null, $append = true ) | ||
$name | string |
The event name |
$handler | callable |
The event handler |
$data | mixed |
The data to be passed to the event handler when the event is triggered. When the event handler is invoked, this data can be accessed via yii\base\Event::$data. |
$append | boolean |
Whether to append new event handler to the end of the existing handler list. If false, the new handler will be inserted at the beginning of the existing handler list. |
public function on($name, $handler, $data = null, $append = true)
{
$this->ensureBehaviors();

Defined in: yii\base\View::render()
Renders a view.
The view to be rendered can be specified in one of the following formats:
- path alias (e.g. "@app/views/site/index");
- absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the view path of the application.
- absolute path within current module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the view path of the current module.
- relative view (e.g. "index"): the view name does not start with
@
or/
. The corresponding view file will be looked for under the view path of the view$context
. If$context
is not given, it will be looked for under the directory containing the view currently being rendered (i.e., this happens when rendering a view within another view).
See also renderFile().
public string render ( $view, $params = [], $context = null ) | ||
$view | string |
The view name. |
$params | array |
The parameters (name-value pairs) that will be extracted and made available in the view file. |

}
Defined in: yii\base\View::renderDynamic()
Renders dynamic content returned by the given PHP statements.
This method is mainly used together with content caching (fragment caching and page caching) when some portions of the content (called dynamic content) should not be cached. The dynamic content must be returned by some PHP statements.
public string renderDynamic ( $statements ) | ||
$statements | string |
The PHP statements for generating the dynamic content. |
return | string |
The placeholder of the dynamic content, or the dynamic content if there is no active content cache currently. Note that most methods that indirectly modify layout such as registerJS() or registerJSFile() do not work with dynamic rendering. |
---|
public function renderDynamic($statements)
{

}
Defined in: yii\base\View::renderFile()
Renders a view file.
If $theme is enabled (not null), it will try to render the themed version of the view file as long as it is available.
The method will call yii\helpers\FileHelper::localize() to localize the view file.
If renderer is enabled (not null), the method will use it to render the view file. Otherwise, it will simply include the view file as a normal PHP file, capture its output and return it as a string.
public string renderFile ( $viewFile, $params = [], $context = null ) | ||
$viewFile | string |
The view file. This can be either an absolute file path or an alias of it. |
$params | array |
The parameters (name-value pairs) that will be extracted and made available in the view file. |
$context | object|null |
The context that the view should use for rendering the view. If null, existing $context will be used. |

Defined in: yii\base\View::renderPhpFile()
Renders a view file as a PHP script.
This method treats the view file as a PHP script and includes the file. It extracts the given parameters and makes them available in the view file. The method captures the output of the included view file and returns it as a string.
