The code will automaticlly generate a filename based on users current time, HTTP_USER_AGENT and users current IP address. I came up with this because Google did not have an easy way to rename an uploaded file that a user wants to upload.

Please folk this code and improve apon it.

1. Install Google/Cloud using composer Google Cloud GitHub
2. Get your .JSON file and verify your domain with google.

Edit google_storage_rename_upload.php

1. Put the name of your bucket here

$b_name = 'BUCKET NAME HERE';

2. Once you have our .json file from google cloud store it in a path that is not accessable via browser (example: /home/ACCOUNTNAME/google/access_key.json) then put that FULL path below.

putenv('GOOGLE_APPLICATION_CREDENTIALS=YOUR PATH TO JSON API CREDENTIALS');

3. Lastly we need to get the projectID from Google Cloud, this should be all numbers.

$storage = new StorageClient([ 'projectId' => 'XXXXXX' ]);

• Creates a new file with the contents of the old file
• Generates a MD5 hashed filename (this should not be used as a key)
• Uploads new file to google
• Deletes the newly created cache file once image is uploaded to Google Storage
• Makes uploaded file public (default) - you can bracket out the code if you don't want the uploads to be public.

• This code does not check to see how big the file is.
• Does not block filetypes (you may want to add this if you are only after images for example)
• Does not check to see if the image has already been uploaded (you could make a script to check if the file contents already exists in your bucket)

• Filetype allow/disallow
• UID
• Geo-location
