Installation

You can install the package via Composer. Run the following command:

composer require sar-cubet/file-upload

Installing the package (publishing the resources)

php artisan fileupload:install

Implementation

We provide SarCubet\FileUpload\Facades\Upload Facade which you can use to perform operations like file validation, image optimization, file storage etc. You can validate your file by using the Upload::validate() method. The Upload::validateFile() accepts a file of type Illuminate\Http\UploadedFile and return a Illuminate\Support\Facades\Validator object that you can use as per the application requirement. All the supported file types can be found inside the config file config/fileupload.php (which will be published). You can modify the config as per your requirement. Also if you wish to add any other file types, you can add it up inside allowed_file_extensions.others list in the config file.

'allowed_file_extensions' => [
    'image' => ['jpeg', 'jpg', 'png', 'gif'],
    'doc' => ['pdf', 'doc', 'docx', 'xls', 'xlsx', 'ppt', 'pptx'],
    'text' => ['txt'],
    'others' => []
]

use SarCubet\FileUpload\Facades\Upload;

$validator = Upload::validateFile($request->file('file'));
if ($validator->fails()) {
    return response()->json(['status' => 0, 'errors' => $validator->errors()]);
}

If you want to use custom validation and/or validation messages you can pass the rules and messages as an associative array (optional)

$rules = [
    'required'      => 'The file is required',
    'mimes:jpg,png' => 'The file types should be any of the following: jpg,png',
    'max:5120'      => 'The file size should not exceed 5MB'
];

$validator = Upload::validateFile($request->file('file'), $rules);

If you wish to scan the uploaded file for any type of malwares. You can use the Upload::scanFile() method(Note: Its recomented to use before using validateFile() or any other services.). Under the hood we are making use of ClamAV anti-virus scanner. So you need to install ClamAV in your machine. Here are the commands for installation (Ubuntu):

# Install clamav virus scanner
sudo apt-get update && sudo apt-get install -y clamav-daemon

# Update virus definitions
sudo freshclam

# Start the scanner service
sudo systemctl enable --now clamav-daemon clamav-freshclam

Additionally you can use isFileInfected() and getMalwareName() methods identify and provide information of any malware like below:

$scan_file = Upload::scanFile($request->file('file'));
        
if ($scan_file->isFileInfected()) {
    return "This file is found with the malware :" . $scan_file->getMalwareName() . '.';
} else {
    return "This file is safe to upload.";
}

You can optimize the image by using Upload::optimizeImage() method. Optimization is provided in 3 levels (excellent, moderate and average).

$file = Upload::optimizeImage($request->file('image'), 'moderate'); 

You can resize the image by using Upload::resize() method. The resize() method accepts 4 parameters: width, height, file and preserve_aspect_ratio (optional)

Upload::resize(200, null, $file);

or

Upload::resize(200, null, $file, true);

File storage is possible through Upload::store() method. store() accepts 3 parameters: file, disk_name, path (optional)

$url = Upload::store($file, 's3');

or

$url = Upload::store($file, 's3', 'your_path');

Chunk file upload functionlaity is provided. You can use Upload::receiveChunks() method to receive chunks and its metadata. You can pass the $request instance into the method. The function will automatically recieve the metadata and each chunks and combine the chunks into a new file when all chunks are received.

use Illuminate\Http\Request;

public function chunkFileUpload(Request $request)
{
    $recieve = Upload::receiveChunks($request);
}

The first Http POST request should contain the metadata and then the chunks should be send. The metadata should contain the data as shown below.

metadata:{
    chunk_size: chunk_size,
    total_chunk_count: total_chunk_count,
    file_size: file_size,
    file_extension: file_extension
}

You can check upload status and store the file like below.

if($receive->isUploadComplete()){
    Upload::store($receive->getFile(), 'public');
}

We also provide two methods for getting the last uploaded chunk and upload progress in percentage.

$receive->getLastUploadedChunkIndex();
$receive->getUploadProgressInPercentage();
