widgets\ActiveField error()

error() public method

Generates a tag that contains the first validation error of $attribute.

Note that even if there is no validation error, this method will still return an empty error tag.

public $this error ( $options = [] )
$options	array\|false	The tag options in terms of name-value pairs. It will be merged with $errorOptions. The options will be rendered as the attributes of the resulting tag. The values will be HTML-encoded using yii\helpers\Html::encode(). If this parameter is `false`, no error tag will be rendered. The following options are specially handled: `tag`: this specifies the tag name. If not set, `div` will be used. See also yii\helpers\Html::tag(). If you set a custom `id` for the error element, you may need to adjust the $selectors accordingly.
return	$this	The field object itself.
