nginx rewrite in subfolder

Question

I'm venturing now into nginx rewrite rules so it's a fairly new topic for me.

I have in the root folder a series of pages which i use rewrite rules as follows:

server { listen 80; ## listen [::]:80 default_server ipv6only=on; listen 443 ssl; root /nginx/gtt/; index index.html index.htm index.php gttindex.php; # Make site accessible from http://localhost/ server_name gtt.deb; ssl_certificate /etc/nginx/ssl/nginx.crt; ssl_certificate_key /etc/nginx/ssl/nginx.key; client_max_body_size 10M; # When access gps page just show gps if ( $request_uri = "/gps" ) { rewrite ^ /gps.lf.ws.vh.sprite.php break; } # Administration if ( $request_uri = "/setup" ) { rewrite ^ /admin.php break; } # For clientadmin show admin if ( $request_uri = "/error" ) { rewrite ^ /gttindex.php?WARNING=wrongcredentials break; } rewrite ^/cargo(.*)$/(.*)$ /clientadmin/edit_task_details_form_multi$1.php?taskid=$2 break; rewrite ^/cargoadmin /clientadmin/admin.php last; location / { index index.html index.htm index.php gttindex.php; try_files $uri $uri/ =404; } } 

will redirect to admin.php

The problem comes when I have to rewrite in a subfolder that contains 4 php scripts:

admin.php edit_task_details_form.php edit_task_details_form_multi2.php edit_task_details_form_multi3.php 

It doesn't work and /cargo2/var or /cargo3/var (depending on which i select) are being appended to the url.

What I'd like to achieve is the following:

http://gtt.deb/clientadmin/admin.php -> http://gtt.deb/cargoadmin

http://gtt.deb/clientadmin/edit_task_details_form_multi.php?task=1 -> http://gtt.deb/cargo/1

http://gtt.deb/clientadmin/edit_task_details_form_multi2.php?task=1 -> http://gtt.deb/cargo2/1

http://gtt.deb/clientadmin/edit_task_details_form_multi3.php?task=1 -> http://gtt.deb/cargo3/1

You are using the rewrite directive wrong. You don't use if with the rewrite rules.

You should write your current rules like this:

rewrite ^/gps$ /gps.lf.ws.vh.sprite.php break; rewrite ^/setup$ /admin.php break; rewrite ^/error$ /gttindex.php?WARNING=wrongcredentials break; 

And most likely you should use last instead of break in the rules.

Regarding the actual issue, try a rewrite like this:

rewrite ^/cargoadmin$ /clientadmin/admin.php; rewrite ^/cargo([0-9]?)/([0-9]+)$ /clientadmin/edit_task_details_form_multi$1.php?task=$2; 

The ([0-9]?) matches all single-digit numbers or an empty string, and captures the number to $1. The ([0-9]+) matches multiple-digit numbers, and captures it into $2 variable.

The $ means that the string must end there, there cannot be any extra characters after that.

On another note, your URL system looks quite complex and it might well cause lots of problems later on. I would pay more attention to develop a simpler and more well defined system to the URL rewriting.
