Views and Blade
Although the Flarum UI you know and love is powered by our Mithril frontend, server-side generated templates are still used throughout Flarum. Most notably, the HTML skeleton of the forum, which includes various SEO meta tags, as well as the no-js view of the forum, is implemented through the Views and Blade systems.
Blade is Laravel's templating engine, which allows you to conveniently generate HTML (or other static content) from PHP. It's the same idea as Jinja or EJS. Views are Laravel's system for organizing/registering Blade templates, and also includes utilities for rendering them and providing them with variables.
For our purposes, views are directories containing
.blade.php template files (possibly contained in subdirectories).
You will need to tell the view factory where it can find your extension's view files by adding a
View extender to
To learn about the syntax for Blade templates, read Laravel's documentation.

You can obtain the view factory instance through dependency injection.
The format is
"VIEW_NAMESPACE::VIEW_NAME". If the view folder is organized as subdirectories, replace
. in the pack.
So if you have a file at
"forum/error.blade.php" in a namespace called
"custom-views", you would use
Note that all Blade templates rendered this way automatically have access to the following variables:
$url: a URL generator instance.
$translator: a Translator instance.
$settings: a SettingsInterface instance.
$slugManager: a SlugManager instance.
Additionally, templates used by content logic have access to
$forum, which represents the Forum API Document's attributes.
If you want to override templates added by core or extensions, set up a view folder structure matching the one you are trying to override, containing just the files you are trying to override. Then use the
