public errorSummary ( Model | Model[] $models, array $options = [] ) : string
$models yii\base\Model | yii\base\Model[] the model(s) associated with this form.
$options array the tag options in terms of name-value pairs. The following options are specially handled: - `header`: string, the header HTML for the error summary. If not set, a default prompt string will be used. - `footer`: string, the footer HTML for the error summary. The rest of the options will be rendered as the attributes of the container tag. The values will be HTML-encoded using [[\yii\helpers\Html::encode()]]. If a value is `null`, the corresponding attribute will not be rendered.
return string the generated error summary.
