Symfony 2 project in nested directory - php

Question

I need to deploy a Symfony 2 project in nested directory on production server. Effectively, this would mean that all URLs are prefixed with /subdirectory/ path, i.e.
http://host.com/subdirectory/project/web/app.php/survey
I don't need URL rewriting and are am not going to set it up. The app should work when accessed via above URL only.
The problem I have is that all links generated by path and asset Twig functions are relative to server root (/), and not subdirectory the project is in (/subdirectory/). Is there any config parameter in Symfony 2 to override relative paths globally?
I tried to work around that problem by adding HTML tag, but it doesn't work for links.
Update: I owe you further details. I'm running IIS with its version of mod_rewrite, so part of your suggestions may still be valid.
Update: Ideally I would like to see a solution that sets root dir on AppKernel object - method AppKernel::setRootDir() had it existed to complement existing AppKernel::getRootDir().

Answer 1

Strange... with default config, path/asset should handle subdirectories. Have you tried it with symfony distribution out-of-the-box? On localhost im mostly using it this way.
Would you mind posting your config file?
Anyway...
For assets paths you could try to configure:
#config.yml
templating:
assets_base_urls: { http: "http://yoursite.com/dir1", ssl: "https://yoursite.com/dir1" }
(http://symfony.com/doc/current/reference/configuration/framework.html#assets-base-urls)
For router you should read: http://symfony.com/doc/current/cookbook/console/sending_emails.html#configuring-the-request-context-globally
It could give you some ideas about changing router context like:
# app/config/parameters.yml
parameters:
router.request_context.host: example.org
router.request_context.scheme: http
router.request_context.base_url: my/path
Anyway - context is automaticlly set based on request information. Try to debug:
$context = $this->getContainer()->get('router')->getContext();
// you should be mainly interested in:
$context->getBaseUrl();
It is possible to easily create listener class which will manually set your base url if anyhow it is wrong:
class RouterContextListener {
protected $router;
public function __construct(RouterInterface $router)
{
$this->router = $router;
}
public function onKernelRequest(Event $event)
{
$this->router->setBaseUrl('somedir');
}
}

You are looking for RewriteBase rule, add it to your in your .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /subdirectory/project/web
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>
Also take a look onto symfony-standard 2.3 .htaccess file, mb it can help
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^app\.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]
# If the requested filename exists, simply serve it.
# We only want to let Apache serve files and not directories.
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .? - [L]
# Rewrite all other queries to the front controller.
RewriteRule .? %{ENV:BASE}/app.php [L]
</IfModule>

Look at app/config/routing.yml where you import routing from your bundles. Records in that file would look similar to this:
somename:
resource: "#YourBundle/Resources/config/routing.yml"
prefix: /
You can add your subdirectory in prefix, like prefix: /subdirectory
Then all generated URLs will include subdirectory.

To enable it the rewrite module, run "apache2 enable module rewrite":
sudo a2enmod rewrite
You need to restart the webserver to apply the changes:
sudo service apache2 restart
VirtualHost should be like this
ServerName localhost.myproject.dev
ServerAdmin webmaster#localhost
DocumentRoot /var/www/project_path
<Directory /var/www/project_path>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /app.php [QSA,L]
</IfModule>
</Directory>
this option is redirect your index.php, index.html or whatever:
Options Indexes FollowSymLinks MultiViews
it will rewrite your htacces!
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /app.php [QSA,L]
</IfModule>

My solution to this on a local environment was adding the following code in app/config/config.yml
framework:
assets:
base_urls:
- 'http://localhost/symfony_dir/'
No rewrite needed!
