nginx with a separate root per subdirectory - php

Question

I'm trying to setup nginx so each path has it's own root directory. This is working for the most part, however POST to php-fpm a throwing a 405.
Currently trying:
location ^~ /foo {
alias /www/foo;
#index index.php;
try_files $uri /www/foo/index.php$request_uri;
access_log /var/log/nginx/foo.log main;
error_log /var/log/nginx/foo.log error;
}
location ^~ /bar {
alias /www/bar;
#index index.php;
try_files $uri /www2/bar/index.php$request_uri;
access_log /var/log/nginx/bar.log main;
error_log /var/log/nginx/bar.log error;
}
location ~ \.php {
set $php_root /usr/local/deploy/baz/current/web;
if ($request_uri ~* /foo ) {
set $php_root /www/foo/current/web;
}
if ($request_uri ~* /bar ) {
set $php_root /www2/bar/current/web;
}
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $php_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $php_root;
include fastcgi_params;
}

Alias does not append location path to the file path. Check the logical flow. If server root is at /var/www/public, foo is located at /var/www/foo/public, bar is located at /var/www/bar/public. Then, this will be the easy config :
server {
root /var/www/public;
...
location /foo {
root /var/www/foo/public;
}
location ~ /foo/.+\.php$ {
fastcgi_param SCRIPT_FILENAME /var/www/foo/public$fastcgi_script_name;
# rest of fastcgi
}
location /bar {
root /var/www/bar/public;
}
location ~ /bar/.+\.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME/var/www/bar/public$fastcgi_script_name;
# rest of fastcgi
}
} # ends server
If you want to use PHP in one directive then :
server {
...
root /var/www/public;
...
location /foo {
root /var/www/foo/public;
}
location /bar {
root /var/www/bar/public;
}
location ~ \.php$ {
set $php_root /var/www/public;
if ($request_uri ~* /foo) {
set $php_root /var/www/foo/public;
}
if ($request_uri ~* /bar) {
set $php_root /var/www/bar/public;
}
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $php_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
...
} # server block ends

If you need more number of path, then you have to symlink.
