How to replace "wp-content/blogs.dir" with "media" for attachment permalinks in a multisite environment?
This is how links look now:
http://url.com/wp-content/blogs.dir/21/files/2011/06/650026_x640_21.jpg -or- http://subdomain.url.com/wp-content/blogs.dir/21/files/2011/06/650026_x640_21.jpg
Ideally this is how the would look:
http://url.com/media/2011/06/650026_x640_21.jpg -or- http://subdomain.url.com/media/2011/06/650026_x640_21.jpg
Thank you!
Actually ... the blogs.dir part isn't used except for internally.
Let's say you have a network with two sites - http://url.com and http://sub.url.com. The files will be located in (respectively):
http://url.com/files/2011/06/...http://sub.url.com/files/2011/06/...The blogs.dir directory is where the images exist physically, yes, but your .htaccess file is routing the virtual directories I just listed above to the correct location.
I'm guessing you're manually putting together the URLs you reference above ... because that's not how Multisite is set up to work by default.
I just tested this on my own network installation to give you a specific example.
My main blog is http://mindsharestrategy.com (custom domain mapped to a subdomain network installation - http://business.eamann.com is the same site). A recent post with images: How to Publish a WordPress Plugin - Subversion.
The first image in the post is: http://mindsharestrategy.com/files/2011/05/checkout.png
But an alternate link that also works: http://eamann.com/wp-content/blogs.dir/2/files/2011/05/checkout.png
WordPress automatically maps the /files directory for this site to /wp-content/blogs.dir/2/files via the .htaccess file.
So your image permalinks will work with the shortened version ... there's nothing you need to do there. It sounds like your problem is actually with the way the [gallery] shortcode outputs content.
<!-- see gallery_shortcode() in wp-includes/media.php --> <div id='gallery-1' class='gallery galleryid-476 gallery-columns-6 gallery-size-photostream'><dl class='gallery-item'><dt class='gallery-icon'><a href='http://sub.url.com/wp-content/blogs.dir/21/files/2011/06/650026_x640_21.jpg' title='650026_x640_21'><img width="143" height="107" src="http://sub.url.com/wp-content/blogs.dir/21/files/2011/06/650026_x640_21-143x107.jpg" class="attachment-photostream" alt="650026_x640_21" title="650026_x640_21" /></a></dt></dl>
Take a look into core:
/wp-includes/ms-default-constants.php > line 21 : UPLOADBLOGSDIR
/wp-includes/ms-default-constants.php > line 27, 28 : BLOGUPLOADDIR
/wp-admin/includes/ms.php > line 91 ; apply_filters( 'wpmu_delete_blog_upload_dir', WP_CONTENT_DIR . "/blogs.dir/{$blog_id}/files/", $blog_id );
I don't know much about WPMU/Network installs, that's such what come up from a cross file search.
