How to upload mpdf file after generating to s3 bucket in php - php

Question

Can I upload mpdf file to s3 server after generating.
$file_name = $pdf->Output(time().'_'.'E-Prescription.pdf','F');

Answer 1

Assuming you have the AWS SDK installed in your project using composer; specifically...
composer require aws/aws-sdk-php
Yes you can, using the stream wrapper like this:
require "vendor/autoload.php";
$aws_file = 's3://bucketname/foldername/your_file_name.pdf';
//the folder is optional if you have one within your bucket
try {
$s3->registerStreamWrapper();
$mpdf->Output($aws_file, \Mpdf\Output\Destination::FILE);
}
catch (S3Exception $e) {
$data['error'] = $e->getMessage();
//show the error as a JSON callback that you can use for troubleshooting
echo json_encode($data);
exit();
}
You might have to add write permissions to your web server as follows (using Apache server on Ubuntu AWS EC2):
sudo chown -R www-data /var/www/html/vendor/mpdf/mpdf/src/Config/tmp
sudo chmod -R 755 /var/www/html/vendor/mpdf/mpdf/src/Config/tmp
Then edit the ConfigVariables.php file found at:
\vendor\mpdf\mpdf\src\Config
Change:
'tempDir' => __DIR__ . '/../../tmp',
To:
'tempDir' => __DIR__ . '/tmp',
Then create an empty folder named 'tmp' in that same directory. Then upload with joy.

// Set yours config's
define("AWS_S3_KEY", "<your_key_here>");
define("AWS_S3_SECRET", "<your_secret_here>");
define("AWS_S3_REGION", "<your_region_here example:us-east-1>");
define("AWS_S3_BUCKET", "<your_bucket_folder_name_here>");

require_once 'mpdf/mpdf.php'; // load yout mdf libe
$mpdf = new mPDF(); // set init object mPDF
$nomeArquivo = md5('cliente_01'); // set file name and cripty this
$mpdf->WriteHTML("Teste upload PDF in s3 bucket");

*/
require_once 'aws/aws-autoloader.php'; // set locate yout lib AWS
$aws_file = 's3://'.AWS_S3_BUCKET.'/'.$nomeArquivo.'.pdf';
$s3 = new Aws\S3\S3Client([
'region' => AWS_S3_REGION,
'version' => 'latest',
'credentials' => [
'key' => AWS_S3_KEY,
'secret' => AWS_S3_SECRET,
]
]);
$s3->registerStreamWrapper();
$mpdf->Output($aws_file); //Send yout mPDF File in s3-file-bucket
} catch (S3Exception $e) {
die($e->getError().' => '.$e->getMessage();
}

To do this you could use the AWS SDK for PHP.
First you will need to create a client using your profile credentials.
use Aws\S3\S3Client;
$client = S3Client::factory(array(
'credentials' => array(
'key' => 'YOUR_AWS_ACCESS_KEY_ID',
'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
)
));
And, if the bucket already exists, you can upload your file from the file system like this:
$result = $client->putObject(array(
'Bucket' => $bucket,
'Key' => $file_name,
'SourceFile' => $pathToFile
));
