源代码

File: wp-includes/ms-default-constants.php

function ms_upload_constants() {
	global $wpdb;

	// This filter is attached in ms-default-filters.php but that file is not included during SHORTINIT.
	add_filter( 'default_site_option_ms_files_rewriting', '__return_true' );

	if ( ! get_site_option( 'ms_files_rewriting' ) )
		return;

	// Base uploads dir relative to ABSPATH
	if ( !defined( 'UPLOADBLOGSDIR' ) )
		define( 'UPLOADBLOGSDIR', 'wp-content/blogs.dir' );

	// Note, the main site in a post-MU network uses wp-content/uploads.
	// This is handled in wp_upload_dir() by ignoring UPLOADS for this case.
	if ( ! defined( 'UPLOADS' ) ) {
		define( 'UPLOADS', UPLOADBLOGSDIR . "/{$wpdb->blogid}/files/" );

		// Uploads dir relative to ABSPATH
		if ( 'wp-content/blogs.dir' == UPLOADBLOGSDIR && ! defined( 'BLOGUPLOADDIR' ) )
			define( 'BLOGUPLOADDIR', WP_CONTENT_DIR . "/blogs.dir/{$wpdb->blogid}/files/" );
	}
}
