php script not executing from subdirectory

Question

Here is the situation. I've setup prestashop 1.7.1 on an ubuntu 14.04 VM running Ajenti, so its php-fpm and nginx for me. After looking through a lot of tutorials and some custom configuration i managed to get everything working just fine. However i just installed a new module and when calling the php file that does the work (generates xml) i am served with the file instead of the proccessed result.I checked file permissions and i even tried 777 on all files. I've noted where the problem is, y nginx configuration is:

set $admin_dir /admin_folder;

gzip on;
gzip_vary on;
gzip_proxied any;

gzip_types
 application/atom+xml
 application/javascript
 application/json
 application/ld+json
 application/manifest+json
 application/rss+xml
 application/vnd.geo+json
 application/vnd.ms-fontobject
 application/x-font-ttf

 text/x-cross-domain-policy;
 # Supposed to be the case but we never know

gzip_disable "MSIE [1-6]\.(?!.*SV1)";

Any suggestions?

Answer 1

You need to include your PHP processing location block inside the .xml block for it to be able to execute PHP scripts. Otherwise it simply does the default which is sending the file directly to the client.

Answer 2

It looks like you're not including any method of actually processing the .php file.

You'll need to add something similar to this into that location:

fastcgi_split_path_info ^(.+?\.php)(/.*)$;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;

Please note that I say "similar" as this will change from server to server depending on your configuration. Nginx needs to know where to pass the php request to, and get the content from fastcgi, so you need to tell it how to do that. The above snippet will do that, maybe :)
