Temproray file upload with S3

Level 58

The error message suggests that the S3 temporary file upload driver only supports single file uploads. Therefore, the solution would be to remove the "multiple" attribute from the input tag.

If you need to upload multiple files, you can loop through the files and upload them one by one. Here's an example using the AWS SDK for PHP:

use Aws\S3\S3Client;

// Initialize S3 client
$s3 = new S3Client([
    'version' => 'latest',
    'region' => 'your-region',
    'credentials' => [
        'key' => 'your-access-key',
        'secret' => 'your-secret-key',
    ],
]);

// Loop through uploaded files
foreach ($_FILES['file']['tmp_name'] as $index => $tmpName) {
    // Generate unique filename
    $filename = uniqid() . '-' . $_FILES['file']['name'][$index];

    // Upload file to S3
    $result = $s3->putObject([
        'Bucket' => 'your-bucket',
        'Key' => $filename,
        'Body' => fopen($tmpName, 'r'),
        'ACL' => 'public-read',
    ]);

    // Get URL of uploaded file
    $url = $result['ObjectURL'];

    // Do something with the URL (e.g. save to database)
}

This code assumes that the uploaded files are stored in the $_FILES superglobal array. You can adjust the S3 client configuration and putObject parameters to fit your needs.
