Available since version | 2.0 |
Breadcrumbs displays a list of links indicating the position of the current page in the whole site hierarchy.
For example, breadcrumbs like "Home / Sample Post / Edit" means the user is viewing an edit page for the "Sample Post". He can click on "Sample Post" to view that page, or he can click on "Home" to return to the homepage.
To use Breadcrumbs, you need to configure its $links property, which specifies the links to be displayed. For example,
// $this is the view object currently being used
echo Breadcrumbs::widget([
'itemTemplate' => "<li><i>{link}</i></li>\n", // template for all links
'links' => [
[
'label' => 'Post Category',
'url' => ['post-category/view', 'id' => 10],
'template' => '<li><b>{link}</b></li>\n', // template for this link only
],
['label' => 'Sample Post', 'url' => ['post/edit', 'id' => 1]],
'Edit',
],
]);
Because breadcrumbs usually appears in nearly every page of a website, you may consider placing it in a layout view.
You can use a view parameter (e.g. $this->params['breadcrumbs']
) to configure the links in different
views. In the layout view, you assign this view parameter to the $links property like the following:
// $this is the view object currently being used
echo Breadcrumbs::widget([
'links' => isset($this->params['breadcrumbs']) ? $this->params['breadcrumbs'] : [],
]);

Property Details
The template used to render each active item in the breadcrumbs. The token {link}
will be replaced with the actual HTML link for each active item.
Whether to HTML-encode the link labels.
The first hyperlink in the breadcrumbs (called home link). Please refer to $links on the format of the link. If this property is not set, it will default to a link pointing to \yii\web\Application::homeUrl with the label 'Home'. If this property is false, the home link will not be rendered.
The template used to render each inactive item in the breadcrumbs. The token {link}
will be replaced with the actual HTML link for each inactive item.
List of links to appear in the breadcrumbs. If this property is empty, the widget will not render anything. Each array element represents a single link in the breadcrumbs with the following structure:
[
'label' => 'label of the link', // required
'url' => 'url of the link', // optional, will be processed by Url::to()
'template' => 'own template of the item', // optional, if not set $this->itemTemplate will be used
]
If a link is active, you only need to specify its "label", and instead of writing ['label' => $label]
,
you should simply use $label
.
The HTML attributes for the breadcrumb container tag.
See also \yii\helpers\Html::renderTagAttributes() for details on how attributes are being rendered.
The name of the breadcrumb container tag.
