How to get element attribute in extension?

Question

Yii

I want to create an extension of this plugin for yii2, but I need to get the id attribute of the used field, relatively speaking
<?= $form->field($model, 'datapicker')->widget(Datapicker::classname(), [...]) ; ?>
I need to get the id of this field. Don't tell me how?

Answer 1

well, in the widget:

echo $this->id;
echo $this->counter;
echo $this->autoIdPrefix;

or

$this->autoIdPrefix = 'mySuperWidget';
echo $this->id;

See what you need. Here is the dock: www.yiiframework.com/doc-2.0/yii-base-widget.html Your widget is inherited from yii\base\Widget, which means that all the charms and methods are available to you.
