submitInput() публичный статический Метод

Be careful when naming form elements such as submit buttons. According to the jQuery documentation there are some reserved names that can cause conflicts, e.g. submit, length, or method.
public static submitInput ( string $label = 'Submit', array $options = [] ) : string
$label string the value attribute. If it is null, the value attribute will not be generated.
$options array the tag options in terms of name-value pairs. These will be rendered as the attributes of the resulting tag. The values will be HTML-encoded using [[encode()]]. If a value is null, the corresponding attribute will not be rendered. See [[renderTagAttributes()]] for details on how attributes are being rendered.
Результат string the generated button tag
    public static function submitInput($label = 'Submit', $options = [])
    {
        $options['type'] = 'submit';
        $options['value'] = $label;
        return static::tag('input', '', $options);
    }
