Preserve cache busting without query strings for WordPress

nginx.md

With this simple plugin, your URLs will be stripped of their query string, but the version is preserved to allow for cache busting.

However you need instruct your webserver to strip the version added in order to let clients use the files.

    location ~ /Versioned/ {
        rewrite ^/Versioned/([^/]+)(/.*)(\.[0-9a-zA-Z]+)$ /$2$3 last;
    }

strip_qstring_static_files.php

<?php
// put this in your must-use plugins path
function _remove_query_strings_1( $src ){
    $host = $_SERVER['HTTP_HOST'];
    $new = preg_replace( "/^(http|https:\/\/)({$host})\/([^?&]+)([&?]+ver=)(.*)$/", "$1$2/Versioned/$5/$3", $src);
    return $new;
}
if ( !is_admin() ) {
        add_filter( 'script_loader_src', '_remove_query_strings_1', 15, 1 );
        add_filter( 'style_loader_src', '_remove_query_strings_1', 15, 1 );
}
