How to Override Templates from Third-Party Bundles

How to Override Templates from Third-Party Bundles

The Symfony community prides itself on creating and maintaining high quality bundles (see KnpBundles.com) for a large number of different features. Once you use a third-party bundle, you'll likely need to override and customize one or more of its templates.

Suppose you've installed an imaginary open-source AcmeBlogBundle in your project. And while you're really happy with everything, you want to override the template for a blog list page. Inside the bundle, the template you want to override lives at Resources/views/Blog/index.html.twig.

To override the bundle template, just copy the index.html.twig template from the bundle to app/Resources/AcmeBlogBundle/views/Blog/index.html.twig (the app/Resources/AcmeBlogBundle directory won't exist, so you'll need to create it). You're now free to customize the template.

Caution

If you add a template in a new location, you may need to clear your cache (php bin/console cache:clear), even if you are in debug mode.

This logic also applies to any template that lives in a bundle: just follow the convention: app/Resources/{BUNDLE_NAME}/views/{PATH/TO/TEMPLATE.html.twig}.

Note

You can also override templates from within a bundle by using bundle inheritance. For more information, see How to Use Bundle Inheritance to Override Parts of a Bundle.

Overriding Core Templates

Since the Symfony Framework itself is just a bundle, core templates can be overridden in the same way. For example, the core TwigBundle contains a number of different "exception" and "error" templates that can be overridden by copying each from the Resources/views/Exception directory of the TwigBundle to, you guessed it, the app/Resources/TwigBundle/views/Exception directory.
