helpers\BaseHtml beginForm()

The form action URL. This parameter will be processed by yii\helpers\Url::to().

The form submission method, such as "post", "get", "put", "delete" (case-insensitive). Since most browsers only support "post" and "get", if other methods are given, they will be simulated using "post", and a hidden input will be added which contains the actual method type. See yii\web\Request::$methodParam for more details.

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.

Special options:

• csrf: whether to generate the CSRF hidden input. Defaults to true.

The generated form start tag.
