Amazon

If you are uploading file to your server and then moving to Amazon S3 then you can choose 'direct upload to Amazon S3' option for your application to replace two steps to one. Also, one advantage of this is uploading directly to Amazon S3 will be faster as Amazon S3 will have enough bandwidth to take file. If you are looking for direct posting file by submitting form then you can follow steps given in Amazon AWS article "Browser Uploads to S3 using HTML POST Forms" but if you like to upload file without refreshing page using Ajax and Bluimp plugin there here is the code for this. To implement this functionality, first of all, you have to add CORS configuration to Amazon S3 bucket. http://www.example.com PUT POST DELETE * * GET You need to download Jquery and blueimp for this plugin. http://blueimp.github.io/jQuery-File-Upload/ <?php $bucket "s3.triotips.com"; $accesskey "AKIAILSadOUXCX6TU7IEVA"; $secret "JmCr3d1W4ZI/BzwOjAFk0AbvNgrk37FtlqxVH"; function getS3Policy() { $now strtotime(date("Y-m-d\TG:i:s")); $expire date('Y-m-d\TG:i:s\Z', strtotime('+30 minutes', $now)); $policy'{ "expiration": "' . $expire .
