Get kernel root dir in Twig template with Symfony 2

Question

I need to get kernel.root_dir in my twig template, I found solutions here, but it does not work. I get error about non existing method Kernel in this class. Realy in GlobalVariables class method getKernel() not exists. So how I can get root_dir in twig template.

(P.S. No I cant get it form controller, and no I cant get it as container parameters)

I suggest you to add a global variable in your config.yml:

# app/config/config.yml
twig:
    # ...
    globals:
        kernelRootDir: "%kernel.root_dir%"

Then, use {{ kernelRootDir }} in your views.

Yes, this nice solution, but I dont want to tie my app to configuration. – nowiko Mar 05 '15 at 07:59
You can also create globals using an extension. But this is quite less friendly than the config file. – Alain Tiemblo Mar 05 '15 at 08:00
Okey, if is single proper way I will axcept your answer. Thanks for help man!) – nowiko Mar 05 '15 at 08:09
Be aware that `%kernel.root_dir%` must be quoted nowadays. – althaus Sep 04 '17 at 14:35

In newer Symfony versions the solution is similar, but the parameter kernel.root_dir has been removed in version 5.0 and the config file for twig is located elsewhere.

Now you can use the kernel.project_dir parameter, which resolves to the projct's root dir (not the kernel's root dir). This is usually the directory where your composer.json is located.

twig:
    globals:
        kernelProjectDir: '%kernel.project_dir%'

Then use {{ kernelProjectDir }} in your templates.
