Upload folder alias – Almost working

Hi @morcth,

Thank you for your message.

Please tell me, are the images in the uploads directory converted correctly to WebP format?

Could you please describe the directory structure to me like this:

├── directory_a
    ├── directory_aa
    ├── directory_ab
├── directory_b
    ├── directory_ba
    ├── directory_bb
├── directory_c

Hi @mateuszgbiorczyk,

Yes, everything is converted flawlessly. If I have plugins, themes and uploads checked, a themes and plugins folder is correctly in the uploads-webpc folder but there is also an srv folder which should be the uploads folder and that srv folder then goes to www then site.com -> shared and finally uploads. Below, the “current” folder is also an alias to the current release.. the server holds the most recent 4 or 5.

Folder structure after conversion:

from /srv/www/site.com/current/web/

├── app 
    ├── mu-plugins
    ├── plugins
    ├── themes
    ├── uploads -> /srv/www/site.com/shared/uploads
    ├── uploads-webpc
        ├── plugins
        ├── themes
        ├── srv
            ├── www        
                ├── site.com
                    ├── shared
                        ├── uploads

All webp images are correctly in uploads.
So, if I leave your nginx settings from your faq as is, all plugin and theme images work but uploads do not. If I change the try statement and put in /app/uploads-webpc/srv/www/site.com/shared/$path.$ext.webp $uri =404; Uploads work but plugins and themes do not.

Thank you for looking into it!

In that case, try the following configuration:

server {
  # ...

  location ~ /wp-content/(?<dir>plugins|themes)/(?<path>.+)\.(?<ext>jpe?g|png|gif)$ {
    if ($http_accept !~* "image/webp") {
      break;
    }
    add_header Vary Accept;
    expires 365d;
    try_files /wp-content/uploads-webpc/$dir/$path.$ext.webp $uri =404;
  }

  location ~ /wp-content/srv/(?<path>.+)\.(?<ext>jpe?g|png|gif)$ {
    if ($http_accept !~* "image/webp") {
      break;
    }
    add_header Vary Accept;
    expires 365d;
    try_files /app/uploads-webpc/srv/www/site.com/shared/srv/$path.$ext.webp $uri =404;
  }
}

I had tried some if statements in the same location block. I was hoping it would be a simple nginx config addition but I am unfamiliar with the format.

I had to change around what you sent a bit but got it working!
Thanks so much for being a freakin genius! Bought you a few cups of coffee.

Awesome plugin and easy setup!

Working code below in case it helps anyone!

location ~ /app/(?<dir>plugins|themes)/(?<path>.+)\.(?<ext>jpe?g|png|gif)$ {
  if ($http_accept !~* "image/webp") {
    break;
  }
  add_header Vary Accept;
  expires 365d;
  try_files /app/uploads-webpc/$dir/$path.$ext.webp $uri =404;
}

location ~ /app/(?<dir>uploads)/(?<path>.+)\.(?<ext>jpe?g|png|gif)$ {
  if ($http_accept !~* "image/webp") {
    break;
  }
  add_header Vary Accept;
  expires 365d;
  try_files /app/uploads-webpc/srv/www/site.com/shared/uploads/$path.$ext.webp $uri =404;
}

Thank you for the detailed description of the case and cooperation. It was a pleasure helping you!

@morcth, if you are satisfied with using the plugin, I will be grateful for adding a review.

Done!

Thanks again

Hi @mateuszgbiorczyk,

New but connected issue that you can hopefully help with.

So I realized that everytime I deploy a new version, the uploads-webpc folder disappears because the “current” folder is another alias to a new release folder: /srv/www/site.com/releases/20200730120153/web/

So I tried creating the uploads-webpc folder in the shared folder where the uploads folder actually lives. This works fine… all images are correctly converted.

The issue now though is that the uploads folder does not have the long path anymore because no alias’s are being used and the themes and plugins folders do.

New folder structure:
From /srv/www/site.com

├── current -> /srv/www/site.com/releases/20200730120153
 ├──web
  ├── app 
    ├── mu-plugins
    ├── plugins
    ├── themes
    ├── uploads -> /srv/www/site.com/shared/uploads
├──shared
  ├── uploads 
  ├── uploads-webpc
    ├── uploads
    ├── srv
      ├── www        
        ├── site.com
          ├── releases
            ├── 20200730120153 --This will always change but maybe can use "current" alias in nginx?
              ├── web
                ├── app
                  ├── plugins
                  ├── themes
├── logs
├── releases

SO, we need the server to check /srv/www/site.com/shared for the uploads-webpc folder which is outside the web/app folder and we need to be able to use “current” alias instead of release location as this will change with every new deployment.

Can we use alias path in nginx conf? Am I able to have the try_files statement in nginx check folders outside of the site root? I also did see that there is an “alias” command for nginx conf.

Any help is appreciated.

Thanks!

@morcth, unfortunately, I am not able to help you here.

I do not have much experience in the configuration server nginx, but I assume that if the directory /uploads will be the root /app directory it will not work.

Please contact the Administrator of your server.

Sadly, I am the admin.

I just saw this:

add_action(‘init’, function()
{
do_action(‘webpc_regenerate_all’);
});

I’m thinking of running a cronjob to check for the uploads-webpc folder every 15 minutes or so. If there, do nothing. If not there, then run the regenerate all action.

So at max, 15 minutes after a new deploy, it will check and see no webp folder and regenerate all.

Can you think of any issues this might cause?

Thanks!

By running the action webpc_regenerate_all, only new images will be converted. The existing ones will not be converted a second time.

The following code should help you:

add_action('webpc_regeneration', function() {
  do_action('webpc_regenerate_all');
});

add_action('init', function() {
  if (wp_next_scheduled('webpc_regeneration')) return;
  wp_schedule_event(time(), 'hourly', 'webpc_regeneration');
});

Everything should run smoothly in the background.

Ok great… so I don’t have to check if the folder exists… just if the cron does.

Every hour it will run and 99% of the time have nothing to convert and once in a while, due to a new deploy, it will not find the uploads-webpc folder at all and will convert all.

Love it.

Will implement tomorrow and report back.

Thanks!
