Quick Start

Basic Usage

use MatthijsNeijenhuijs\FilamentQrButton\QrCodeColumn;

public static function table(Table $table): Table
{
    return $table
        ->columns([
            TextColumn::make('name'),
            
            QrCodeColumn::make('qr_code')
                ->qrUrl('url') // Column containing the URL
                ->buttonLabel('View QR'),
        ]);
}

Dynamic URL Generation

QrCodeColumn::make('qr_code')
    ->qrUrl(fn ($record) => route('products.show', $record))
    ->buttonLabel('Product QR')
    ->modalHeading('Product QR Code')

Configuration Options

Note: We use qrUrl() instead of url() to avoid conflicts with Filament's built-in url() method on table columns, which is used for making the entire column clickable.

URL Source

Define where to get the URL from:

// From a database column
QrCodeColumn::make('qr_code')
    ->qrUrl('product_url')

// Using a closure for dynamic URL generation
QrCodeColumn::make('qr_code')
    ->qrUrl(fn ($record) => "https://example.com/track/{$record->tracking_code}")

QR Code Size

Set the size of the generated QR code (in pixels):

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->size(200) // Default is 150

Button Label

Customize the button text:

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->buttonLabel('Show QR Code')

Modal Configuration

Control the modal display:

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->showInModal(true) // Default is true
    ->modalHeading('Scan this QR Code')

Display Inline (Without Modal)

Show the QR code directly in the table:

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->showInModal(false)
    ->size(80) // Smaller size for inline display

Error Correction Level

Set the QR code error correction level:

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->errorCorrectionLevel('H') // High error correction

Error correction levels:

• L - Low (7% correction)
• M - Medium (15% correction) - Default
• Q - Quartile (25% correction)
• H - High (30% correction)

Output Format

Choose the output format:

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->format('svg') // svg, png, eps, pdf (default: svg)

Real-World Examples

Product URL QR Code

QrCodeColumn::make('product_qr')
    ->label('Product QR')
    ->qrUrl(fn ($record) => route('products.public', $record))
    ->buttonLabel('QR Code')
    ->modalHeading('Product QR Code')
    ->size(200)
    ->errorCorrectionLevel('H')

Order Tracking QR Code

QrCodeColumn::make('tracking_qr')
    ->label('Tracking')
    ->qrUrl(fn ($record) => "https://tracking.example.com/{$record->tracking_number}")
    ->buttonLabel('Track')
    ->modalHeading('Track Your Order')

Warehouse Location QR Code

QrCodeColumn::make('location_qr')
    ->label('Location')
    ->qrUrl(fn ($record) => route('warehouse.location', ['location' => $record->location_code]))
    ->buttonLabel('Location QR')
    ->size(150)

Invoice QR Code (Inline Display)

QrCodeColumn::make('invoice_qr')
    ->label('Invoice QR')
    ->qrUrl(fn ($record) => route('invoices.download', $record))
    ->showInModal(false)
    ->size(60)

Advanced Usage

Conditional Display

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->visible(fn ($record) => $record->is_active && $record->url !== null)

Dynamic Button Labels

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->buttonLabel(fn ($record) => $record->qr_label ?? 'QR Code')

Dynamic Size

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->size(fn ($record) => $record->is_important ? 200 : 150)

Custom Modal Headings

QrCodeColumn::make('qr_code')
    ->qrUrl('url')
    ->modalHeading(fn ($record) => "QR Code for {$record->name}")

Complete Example

Here's a complete example in a Filament resource:

<?php

namespace App\Filament\Resources;

use App\Models\Product;
use MatthijsNeijenhuijs\FilamentQrButton\QrCodeColumn;
use Filament\Resources\Resource;
use Filament\Tables\Table;
use Filament\Tables\Columns\TextColumn;

class ProductResource extends Resource
{
    protected static ?string $model = Product::class;

    public static function table(Table $table): Table
    {
        return $table
            ->columns([
                TextColumn::make('reference_code')
                    ->searchable(),
                    
                TextColumn::make('name')
                    ->searchable(),
                    
                TextColumn::make('ean')
                    ->label('EAN')
                    ->searchable(),
                    
                QrCodeColumn::make('product_qr')
                    ->label('QR Code')
                    ->qrUrl(fn ($record) => route('products.show', $record))
                    ->buttonLabel('View QR')
                    ->modalHeading('Product QR Code')
                    ->size(180)
                    ->errorCorrectionLevel('H'),
            ]);
    }
}

Configuration File

The default configuration can be customized in config/filament-qr-button.php:

return [
    'default_size' => 150,
    'default_error_correction' => 'M',
    'default_format' => 'svg',
    'default_button_label' => 'QR Code',
    'show_in_modal' => true,
    'default_modal_heading' => 'QR Code',
];

Tips & Best Practices

1. Performance: For large tables, enable pagination to avoid generating too many QR codes at once
2. Size: Keep QR codes between 100-200px for optimal scanning
3. Error Correction: Use higher error correction (Q or H) for QR codes that might be damaged
4. URLs: Ensure URLs are publicly accessible if QR codes will be scanned by external users
5. Testing: Always test QR codes with different scanner apps

Troubleshooting

QR Code Not Displaying

• Ensure the URL attribute exists on your model
• Check that the URL is not null or empty
• Verify dependencies are installed: composer show lara-zeus/simple-qrcode

Modal Not Opening

• Clear your browser cache
• Ensure Livewire is properly loaded
• Check browser console for JavaScript errors

QR Code Quality Issues

• Increase the size() parameter
• Use a higher errorCorrectionLevel() (Q or H)
• Consider using SVG format for better quality

Testing

composer test
