Resource Versioning

Turn Query String Parameters into file revision numbers.

It is much easier to use a CDN without Query String Parameters. This plugins alters only local resources' URL-s. The ver Query String Parameter will be inserted into the filename.

jquery.min.js?ver=1.10 becomes jquery.min.110.js

To "revert" that change add this line to your nginx config:

server {
    location ~ ^(.+)\.\d\d+\.(js|css|png|jpg|jpeg|gif|ico)$ {
        #try_files $uri $1.$2 /index.php?$args;
        try_files $uri $1.$2 =404;
    }
}

Or to your Apache config or .htaccess file.

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)\.\d\d+\.(js|css|png|jpg|jpeg|gif|ico)$ $1.$2 [NC,L]

Testing the plugin before live usage

You can test the plugin by replacing the two add_filter() calls with this

require_once dirname( dirname( dirname( dirname( __FILE__ ) ) ) ) . '/wp-load.php';
wp();
echo o1_revving_src( $argv[1] ) . PHP_EOL;

Then start it from CLI: php revving.php <TEST-URL>

How to remove all Query String Parameters from resources?

Poorly written plugins and themes may add unwanted Query String Parameters. For example ?rev=4.10.

To drop all these parameters copy this into your wp-config.php

define( 'O1_REMOVE_ALL_QARGS', true );
