Requirements

• PHP >= 8.0
• Laravel 9.x, 10.x, 11.x, 12.x, or 13.x
• ClamAV anti-virus scanner running on the server

You can see the ClamAV installation instructions on the official ClamAV documentation.

For example on an Ubuntu machine, you can do:

# 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

This package is not tested on Windows, but if you have ClamAV running (usually on port 3310) it should work. You will also need to have sockets extension installed and enabled (all executions without this module will fail with this error - "Use of undefined constant 'AF_INET'").

Installation

1. Install the package through Composer.

composer require sunspikes/clamav-validator

2. Publish assets from the vendor package

Config file

The default configuration file does use ENV to override the defaults. If you want to change the configuration file anyway you run the following command to publish the package config file:

php artisan vendor:publish --provider="Sunspikes\ClamavValidator\ClamavValidatorServiceProvider" --tag=config

Once the command is finished you should have a config/clamav.php file that will be used as well.

Language files

If you want to customize the translation or add your own language you can run the following command to publish the language files to a folder you maintain:

php artisan vendor:publish --provider="Sunspikes\ClamavValidator\ClamavValidatorServiceProvider" --tag=lang

This will copy the language files to lang/vendor/clamav-validator.

Configuration

The package can be configured using environment variables:

Usage

Use it like any Validator rule:

$rules = [
    'file' => 'required|file|clamav',
];

Or in a Form Request:

class UploadRequest extends FormRequest
{
    public function rules(): array
    {
        return [
            'file' => 'required|file|clamav',
        ];
    }
}

ClamavValidator will automatically run multiple files one-by-one through ClamAV in case file represents multiple uploaded files.
