Subject

I have a hybrid page, created and configured using SonataAdminBundle+SonataPageBundle. Suppose it’s has “old title” as title. And I want to change title at runtime (which will be later rendered by sonata_seo_title() Twig helper). Using SeoPage->setTitle() doesn’t works for me.

Steps to reproduce

Set title “old title” to some hybrid page through admin interface. In controller action for this page, try to change title:

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class MyController extends Controller
{
    public function someAction(Request $request)
    {
        // ...
        $seoPage = $this->get('sonata.seo.page');
        $seoPage->setTitle('new title');
        // ...
        return $this->render('template.html.twig');
    }
}

<!-- template.html.twig -->
<!DOCTYPE html>
<html>
    <head>
        {{ sonata_seo_title() }}
    </head>
</html>

Expected results

sonata_seo_title() output:

<title>new title</title>

Actual results

<title>old title</title>

Thanks so much @Neodork! It worked perfectly and it’s really good to know, might be useful again in the future!

Hello @Aylarius

As mentioned by Rande, you are supposed to override the PageService. I can imagine that overriding it can be hard for new Sonata users. So I’ll go over the basics a bit to help you out.

In Sonata most important services and classes have been set as “Parameter”. This way you can override these services without accessing or modifying the vendor bundle. In our case we’re looking to override sonata.page.service.default.class. Look at the example below.

Note: It’s also possible to edit parameters programmatically.

# app/config/parameters.yml

parameters:
    database_host: 127.0.0.1
    database_port: null
    database_name: name
    database_user: root
    database_password: root
    mailer_transport: smtp
    mailer_host: 127.0.0.1
    mailer_user: null
    mailer_password: null
    ...
    sonata.page.service.default.class: Neodork\AppBundle\Page\Service\DefaultPageService

Now that we set the new service make sure to create it. The simplest way to do this is copying DefaultPageService from the vendor bundle. And pasting it at the location specified in the parameters.yml file. In this case that would be Neodork\AppBundle\Page\Service\DefaultPageService.

Now clear your cache and the new service should be in use. Modify it to suit your needs and you’re done!

@greg0ire the code is part of the PageBundle
