Filter function to fix uploads directory (customized WordPress paths)

README.md

Moving WordPress to custom subdirectory and customize its managed paths

This is a must-use plugin to fix your uploads paths (URL & directory), for advanced paths customization for your wordpress intallation.

• WordPress is installed at /wp subdirectory.

//wp-config.php
define('WP_HOME', 'http://example.com');
define('WP_SITEURL', 'http://example.com/wp');

• WordPress front controller point to that directory

//index.php
/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp/wp-blog-header.php' );

• Content dir is at /, not subdirectory

define('WP_CONTENT_DIR', dirname(__FILE__) );
define('WP_CONTENT_URL', WP_HOME );

• Plugins are located in /extensions

define('WP_PLUGIN_DIR', WP_CONTENT_DIR . '/extensions');
define('WP_PLUGIN_URL', WP_HOME . '/extensions');

• Must use plugins located in /must

define('WPMU_PLUGIN_DIR', WP_CONTENT_DIR . '/must');
define('WPMU_PLUGIN_URL', WP_CONTENT_URL . '/must');

• Uploads placed in /media

define('UPLOADS', '../media'); // relative to ABSPATH, if you use only "media", it'd be "/wp/media"

However the uploaded files will have a URL like http://example.com/wp/../media/2017/01/media1.jpg

To fix this you place the PHP file into the /must plugins directory.

If you want to put your uploads directory in "/media" (i.e.: http://yoursite.net/media) instead of "wp-content/uploads".
