Class yii\bootstrap\ActiveForm
Inheritance | yii\bootstrap\ActiveForm » yii\widgets\ActiveForm » yii\base\Widget » yii\base\Component » yii\base\BaseObject |
---|---|
Implements | yii\base\Configurable, yii\base\ViewContextInterface |
Available since version | 2.0 |
Source Code | https://github.com/yiisoft/yii2-bootstrap/blob/master/ActiveForm.php |
A Bootstrap 3 enhanced version of yii\widgets\ActiveForm.
This class mainly adds the $layout property to choose a Bootstrap 3 form layout. So for example to render a horizontal form you would:
use yii\bootstrap\ActiveForm;
$form = ActiveForm::begin(['layout' => 'horizontal'])
This will set default values for the yii\bootstrap\ActiveField
to render horizontal form fields. In particular the template
is set to {label} {beginWrapper} {input} {error} {endWrapper} {hint}
and the
horizontalCssClasses are set to:
[
'offset' => 'col-sm-offset-3',
'label' => 'col-sm-3',
'wrapper' => 'col-sm-6',
'error' => '',
'hint' => 'col-sm-3',
]
To get a different column layout in horizontal mode you can modify those options through $fieldConfig:
$form = ActiveForm::begin([
'layout' => 'horizontal',
'fieldConfig' => [
'template' => "{label}\n{beginWrapper}\n{input}\n{hint}\n{error}\n{endWrapper}",
'horizontalCssClasses' => [
'label' => 'col-sm-4',
'offset' => 'col-sm-offset-4',
'wrapper' => 'col-sm-8',
'error' => '',
'hint' => '',
],
],
]);

The form layout. Either 'default', 'horizontal' or 'inline'. By choosing a layout, an appropriate default field configuration is applied. This will render the form fields with slightly different markup for each layout. You can override these defaults through $fieldConfig.
See also yii\bootstrap\ActiveField for details on Bootstrap 3 field configuration.
Method Details
Defined in: yii\base\Component::__call()
Calls the named method which is not a class method.
This method will check if any attached behavior has the named method and will execute it if available.
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
public mixed __call ( $name, $params ) | ||

}
}
throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
Defined in: yii\base\Component::__clone()

}
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.

}
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;
.

}
Defined in: yii\base\Component::__isset()
Checks if a property is set, i.e. defined and not null.
This method will check in the following order and act accordingly:
- a property defined by a setter: return whether the property is set
- a property of a behavior: return whether the property is set

}
Defined in: yii\base\Widget::afterRun()
This method is invoked right after a widget is executed.
The method will trigger the EVENT_AFTER_RUN event. The return value of the method will be used as the widget return value.
If you override this method, your code should look like the following:
public function afterRun($result)
{
$result = parent::afterRun($result);
// your custom code here
return $result;
}
public mixed afterRun ( $result ) | ||
$result | mixed |

$this->trigger(self::EVENT_AFTER_RUN, $event);
return $event->result;
}
Defined in: yii\base\Component::attachBehavior()
Attaches a behavior to this component.
This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the yii\base\Behavior::attach() method.
See also detachBehavior().
public yii\base\Behavior attachBehavior ( $name, $behavior ) | ||
$name | string |
The name of the behavior. |
$behavior | string|array|yii\base\Behavior |

---|
public function attachBehavior($name, $behavior)
{
$this->ensureBehaviors();
return $this->attachBehaviorInternal($name, $behavior);
}
Defined in: yii\base\Component::attachBehaviors()
Attaches a list of behaviors to the component.
Each behavior is indexed by its name and should be a yii\base\Behavior object, a string specifying the behavior class, or an configuration array for creating the behavior.
See also attachBehavior().
public void attachBehaviors ( $behaviors ) | ||
$behaviors | array |
List of behaviors to be attached to the component |
public function attachBehaviors($behaviors)
{
$this->ensureBehaviors();
foreach ($behaviors as $name => $behavior) {
$this->attachBehaviorInternal($name, $behavior);
}
}
Defined in: yii\base\Widget::beforeRun()
This method is invoked right before the widget is executed.
The method will trigger the EVENT_BEFORE_RUN event. The return value of the method will determine whether the widget should continue to run.
When overriding this method, make sure you call the parent implementation like the following:
public function beforeRun()
{
if (!parent::beforeRun()) {
return false;
}
// your custom code here
return true; // or false to not run the widget
}
public boolean beforeRun ( ) | ||
return | boolean |
Whether the widget should continue to be executed. |
---|
public function beforeRun()
{
$event = new WidgetEvent();
$this->trigger(self::EVENT_BEFORE_RUN, $event);
return $event->isValid;
}
Defined in: yii\base\Widget::begin()
Begins a widget.
This method creates an instance of the calling class. It will apply the configuration to the created instance. A matching end() call should be called later. As some widgets may use output buffering, the end() call should be made in the same view to avoid breaking the nesting of output buffers.
See also end().
public static static begin ( $config = [] ) | ||
$config | array |
Name-value pairs that will be used to initialize the object properties |
return | yii\base\Widget |
The newly created widget instance |

$widget = Yii::createObject($config);
self::$stack[] = $widget;
return $widget;
}
Defined in: yii\widgets\ActiveForm::beginField()
Begins a form field.
This method will create a new form field and returns its opening tag. You should call endField() afterwards.
See also:
public string beginField ( $model, $attribute, $options = [] ) | ||
$model | yii\base\Model |
The data model. |
$attribute | string |
The attribute name or expression. See yii\helpers\Html::getAttributeName() for the format about attribute expression. |

The opening tag. |
---|
public function beginField($model, $attribute, $options = [])
{
$field = $this->field($model, $attribute, $options);
$this->_fields[] = $field;
return $field->begin();
}
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).

$checkVars
is true); - an attached behavior has a readable property of the given name (when
$checkBehaviors
is true).

}
Defined in: yii\base\Component::canSetProperty()
Returns a value indicating whether a property can be set.
A property can be written if:
- the class has a setter 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 writable property of the given name (when

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.');
});
