I have resolved this issue using below code instead of creating config.php file.
$config = array(
'key' => '----------KEY-----------',
'secret' => '-----SECRET KEY---------------',
'region' => 'us-east-1'
);
$this->s3 = Aws::factory($config)->get('s3')->registerStreamWrapper();

I am facing one more issue related to generate thumbnail using imagick. It is showing error like:

Fatal error: Uncaught exception 'ImagickException' with message 'unable to open image `s3://bucketname/uploads/2014/03/24/Wallpaper1 (1).jpg': No such file or directory @ error/blob.c/OpenBlob/2643' in /var/www/domain.com/public/2014/file_upload/server/php/UploadHandlerS3.php:991

Please help me to resolve above issue.
Thanks in advance

@bijalbhavsar did you solve your problem?

Hey, How can I add ACL here?

@indicalabs
Copy link

@tim-peterson
Thanks for the great work. I am able to upload successfully to s3 but the uploaded documents are 'private' by default, how to add ACL, policy, Signature.
One important question is that the documents are having the 'tmp_name' property, like below 'tmp_name' => [
'file' => '/private/var/tmp/phpQda26G'
]

that means the documents are comming to Webserver.
Is it not Direct Browser Upload? Is it same as PutObject?

@tim-peterson
This is great, we've been adapting this to work with Yii and it works great. However we also have the same problem with ACL that @bijalbhavsar and @venu85 have. When we upload files, they're private.

Somehow we need to specify ACL => 'public-read', but we can't see how to do this in an option or setting anywhere.

Thanks

As an interim fix, this is what we ended up doing: just after the call to move_uploaded_file we added a call to putObjectAcl, as follows:

                else {
                    move_uploaded_file($uploaded_file, $file_path);
                    $key = $this->prefix . $name;
                    $this->s3->putObjectAcl(array(
                        'ACL' => 'public-read',
                        'Bucket' => $this->bucket,
                        'Key' => $key,
                    ));
                }

It's not very elegant, but at least it works.

@tim-peterson,
Is it possible to upload files directly to S3 from Dropbox without downloading first on my local or on server first?
Thanks

Thank you @isocra :) That did the trick!

Improvement on @isocra's hack:

move_uploaded_file($uploaded_file, $file_path);
$key = $this->prefix . basename($file_path);
$this->s3->putObjectAcl(array(
  'ACL' => 'public-read',
  'Bucket' => $this->bucket,
  'Key' => $key,
));

I use basename($file_path) instead of $name to handle the cases when you upload a file with a repeated filename

Does anybody get it working perfectly with image scale with all sizes?

This is what I got:

Warning: imagepng(): Unable to open 's3: ...

About the code line: ) && $write_func($new_img, $new_file_path, $image_quality);

@cassianotartari

Finally get it working, using GD library I've changed the final of method gd_create_scaled_image to this:

$success = imagecopyresampled(
            $new_img,
            $src_img,
            $dst_x,
            $dst_y,
            0,
            0,
            $new_width,
            $new_height,
            $img_width,
            $img_height
        );

        ob_start();
        $result = $write_func($new_img, NULL, $image_quality);
        if ($result) {
             $contents = ob_get_contents();
             ob_end_clean();
        }
        $this->gd_set_image_object($file_path, $new_img);

         $context = stream_context_create(array(
            's3' => array(
                'ACL' => \AmazonS3::ACL_PUBLIC,
                'ContentType' => $this->get_file_type($file_path)
            )
        ));

        return file_put_contents($new_file_path, $contents, null, $context);

The $write_func functions (imagegif, imagepng, imagejpeg) doesn't work with stream wrapper so I've done that using a buffer and writing the result to server using file_put_contents

Hope it help somebody.

@bijalbhavsar, take a look.

This script does not directly upload to s3 for me. Files are still being stored in the servers /tmp folder and then hitting upload limits from cloudflare.

@thond1st - Any luck with uploading directly to s3 from dropbox?

This script is basically exactly what i'm looking for but i'm not really sure how the connect it to the "File Upload Plugin". This is basically a class definition but how to the hook this up to the AJAX request from the "File Upload Plugin"? Do I just create a class instance on the page that AJAX calls?

What am I suppose to pass in? $options = null, $initialize = true, $error_messages = null

options - Does this value matter? Looks like it will be overwritten anyways?
initalize - I would pass true here
error_messages - not sure what I should pass here

Also, I want to update my mysql database when files are upload / deleted. Should I just add this to the post() and delete() methods or is there a better way way? Should I update mysql db in the head() method to, but really sure what head() does

Thanks in advance!

Thanks for this. Trying to get this script to work however, the file upload but then the script fails.
The file does initially load to the profiles directory but then stops afterwards, please see error below

This is working fine for me except performance seems low. I am uploading at about 300 kbps on a connection that provides almost 2 mbps for ftp to the server (no s3). The issue seems to be that transfers are limited to 6 concurrent session for some reason. I have tried increasing the concurrency in $config but it doesn't seem to impact throughput. Any thoughts on improving throughput?

OH... using GD instead of ImageMagick works in line #126. So I guess I'll just go that route. Thanks

It works for me, thanks.

does any one know how to use this with bucketname.s3-accelerate.amazonaws.com – to access an acceleration-enabled bucket. To make uploads faster. Since it takes million years currently.
