Multiple CSV Files

QR Images now supports processing multiple CSV files:

# Process multiple CSV files
bin/application save-image --file=office.csv --file=home.csv

# Process all CSV files in resources directory
bin/application save-image --all

# Process with wildcards
bin/application save-image "data/*.csv"

CSV File Format

Your CSV file should have the following format (3 columns minimum):

1,WIFI:S:SK_WiFiGIGADDF0_5G;T:WPA;P:JSV38@6701;;,WIFI:S:SK_WiFiGIGADDF0_2.4G;T:WPA;P:JSV38@6701;;
2,WIFI:S:SK_WiFiGIGADDF4_5G;T:WPA;P:KSV21@6702;;,WIFI:S:SK_WiFiGIGADDF4_2.4G;T:WPA;P:KSV21@6702;;

• Column 1: Network number (integer)
• Column 2: 5GHz WiFi QR code string
• Column 3: 2.4GHz WiFi QR code string

Notice

Ensure that the source file is not saved as UTF-8 with BOM. If your source file is currently in UTF-8 with BOM, please save it again as UTF-8 (without BOM).

Configuration

QR Images now supports flexible configuration through multiple methods.

Configuration File

Create a config/qr-images.php file in your project root:

<?php

return [
    // CSV file configuration
    'csv_file' => 'SSID_QR.csv',

    // QR Code settings
    'qr_code' => [
        'eccLevel' => \chillerlan\QRCode\QRCode::ECC_L,  // Error correction: L, M, Q, H
        'version' => 3,                // QR version (1-40)
        'quietzoneSize' => 4,          // Quiet zone size
    ],

    // Paths configuration
    'paths' => [
        'resources' => 'resources',
        'export' => 'resources/export',
        'images' => 'resources/images',
    ],
];

Environment Variables

Override configuration using environment variables:

# Override CSV file
QR_CSV_FILE=custom.csv bin/application save-image

# Override QR code settings

1. Default configuration (hardcoded)
2. config/qr-images.php file
3. Custom config file (via Config::load())
4. .env file
5. Environment variables
