Breadcrumbs in CakePHP

I hope this helps you . You can see that the getCrumbs is hardcoded to '/'. You'll have to override getCrumbs to linking to admin, or alternatively just add an

$this->Html->addCrumbs('Admin','/admin');

I hope this helps you . The $options parameter is only used if you are outputting a link. You could try something like this instead:

$this->Html->addCrumb('<span id="crumbselected">' . $news['News']['title'] . '</span>',null);

I hope this helps . Double check the render call with Breadcrumb::render() in your Blade template:
It seems you're not passing a $product object:

{!! Breadcrumbs::render('product.detail', $user, $product) !!}
                                                 ^^^^^^^^ Did you forget this one?

route('product.detail', $product->id)
route('user.detail', $user->id)

I hope this helps . Yet another question due to the poor Cake 3 documentation...

$this->Breadcrumbs->add('Products',
    ['controller' => 'products', 'action' => 'index']);

echo $this->Breadcrumbs->render();
