How to update older Image URLs?

yup, same question here.
moving older image to s3
thanks in advance

Hey @sforsberg,

That is a good idea, any other ideas on what you would do for media which isn’t images, such as pdf’s etc ?

Cheers.

Not sure if this will help, but this is how I think we are going to deal with this.

For images already placed in posts and pages, we’ve used a redirect in our .htaccess file. for our regular non-multi site wp, we’ve used:
RewriteRule ^wp-content/uploads/(.*)$ https://thebucketname.s3.amazonaws.com/wp-content/uploads/$1 [L]
of course your path might be different.

For our wp-mu site we’ve created our own ms-files.php to point to our s3 path and then pointed to it via .htaccess ala this:
RewriteRule ^(.*/)?files/(.*) wp-content/mu-plugins/vital-scripts/ourown-ms-files.php?file=$2 [L]

in that file basically we’ve replaced:
$file = rtrim( BLOGUPLOADDIR, '/' ) . '/' . str_replace( '..', '', $_GET[ 'file' ] );
with
$file = "{$bucket}.s3.amazonaws.com/blogs.dir/{$blog_id}/files" . '/' . str_replace( '..', '', $_GET[ 'file' ] ) ;
we also removed/updated some of the code to work with S3.

This is the down and dirty that we’ve done but since the plugin creates a global object of
$as3cf you could use that to get your bucket and other features set via the plugin to use in various urls.

So far it seems to be working.

Not implemented but and idea for older images that haven’t been place into posts yet, you could use the wp_get_attachment_url filter to filter the url before it gets inserted. Doing it on the fly would basically eliminate the need to update the db. Just a thought.

thanks

I used the plugin Velvet Blues Update URLs and it worked great for changing the URLs in my posts and pages. But when I am in my WP admin and look at the media library, all of the images that I transferred myself to my S3 bucket don’t show thumbnails. I’ll have to try the regenerate thumbnails to see if that does it. I can probably make changes in my database, but . . .

Samb_nz–the velvet blues plugin should work for other files as well.

@tracibunkers I also ended up using an .htaccess file in the wp-uploads dir that just redirects to the s3 bucket, and manually uploaded all my old media. That way I didn’t have to alter anything in wordpress, then this plugin takes care of any new files.

Yeah @tracibunkers,

I used the .htaccess, which meant everything worked as normal in the wordpress admin.

I figured it out:

1. With some basic SQL knowledge you can determine all posts of post type attachment that do not have an entry with the meta_key “amazonS3_info” in the table wp_postmeta.
2. Extract the file name of each attachment from the old guid in wp_posts.
3. Add for each attachment a line like the following to functions.php and refresh the website: add_post_meta( 2868, 'amazonS3_info', array('bucket' => "your-bucket", 'key' => "path/to/media/in/bucket"));
