Sonata Admin: Add custom triggers/actions to list/edit action

To add an action for edit form

Add to your admin class:

protected function configureSideMenu(MenuItemInterface $menu, $action, Admin $childAdmin = null){    if (!$childAdmin && !in_array($action, array('edit'))) {        return;    }    $admin = $this->isChild() ? $this->getParent() : $this;    $id = $admin->getRequest()->get('id');    $menu->addChild('My action', array('uri' => 'http://google.com?id=' . $id));}

It will create left side menu for actions like /admin/acme/videos/x/edit/. Having id for current item allows you to build any custom URL.

To add an action for list:In your admin file add

protected function configureListFields(ListMapper $listMapper){    $listMapper        ->add('_action', 'actions', array(            'actions' => array(                'act' => array('template' => 'AcmeBundle:Video:my_temp.html.twig'),            )        ))    ;}

It will add a column with links, then you need to create a template for your column, something like

<a href="{{ admin.generateObjectUrl('delete', object) }}" class="delete_link" title="{% trans from 'SonataAdminBundle' %}action_delete{% endtrans %}">    <img src="{{ asset('bundles/sonataadmin/famfamfam/delete.png') }}" alt="{% trans from 'SonataAdminBundle' %}action_delete{% endtrans %}" /></a>

All examples are taken from link that you provided. Hope it helps
