README

A Laravel package for generating PDF invoices with full RTL support, specifically designed for Persian (Farsi) language invoices using the mPDF library.

Features

• Generates PDF invoices with complete RTL and Persian font support (Vazir font by default).
• Structured data management using Seller, Buyer, Bank, Product, and Invoice classes.
• Customizable invoice templates using Blade views.
• Configurable default font and theme via a configuration file.
• Seamless integration with Laravel 12.
• Supports dynamic data injection for invoices.
• Includes a test route for easy development and testing.

Requirements

• PHP >= 8.1
• Laravel >= 12.0
• mPDF >= 8.2

Installation

1. Install via Composer:

   composer require rmscms/pdf

2. Publish Assets: Publish fonts, views, and configuration to your project:

   php artisan vendor:publish --tag=rms-pdf-fonts
   php artisan vendor:publish --tag=rms-pdf-views
   php artisan vendor:publish --tag=rms-pdf-config

   This copies:

   • Vazir fonts to public/vendor/rms-pdf/fonts.
   • Blade templates to resources/views/vendor/rms-pdf.
   • Configuration file to config/rms-pdf.php.

3. Verify Dependencies: The mpdf/mpdf:^8.2 dependency is automatically included via the package's composer.json.

Configuration

The package uses the Vazir font and elegant template by default for Persian text. These can be customized in the config/rms-pdf.php file:

return [
    'default_font' => 'vazir',
    'default_theme' => 'elegant',
    'fontdata' => [
        'vazir' => [
            'R' => 'Vazir.ttf',
            'B' => 'Vazir-Bold.ttf',
            'useOTL' => 0xFF,
            'useKashida' => 75,
        ],
    ],
];

Adding Custom Fonts

To use a different font (e.g., IRANSans), place the .ttf files in your project's public/vendor/rms-pdf/fonts after publishing, and update config/rms-pdf.php:

return [
    'default_font' => 'iransans',
    'default_theme' => 'elegant',
    'fontdata' => [
        'iransans' => [
            'R' => 'IRANSans.ttf',
            'B' => 'IRANSans-Bold.ttf',
            'useOTL' => 0xFF,
            'useKashida' => 75,
        ],
    ],
];

Run the publish command to ensure fonts are available:

php artisan vendor:publish --tag=rms-pdf-fonts

Usage

The package provides a PDF facade to generate invoices. Data is structured using the Seller, Buyer, Bank, Product, and Invoice classes.

Classes

• Seller: Manages seller information and bank details.
  • Properties: company, address, postal_code, phone, bank (instance of Bank).
• Bank: Manages bank account details.
  • Properties: account_holder, card_number, sheba.
• Buyer: Manages buyer information.
  • Properties: name, address, postal_code, phone.
• Product: Represents a single invoice item.
  • Properties: description, quantity, unit_price, total.
• Invoice: Manages invoice details and a collection of products.
  • Properties: title, subtitle, invoice_number, invoice_date, reference, total_items, postage_cost, discount, discount_note, final_amount, products (array of Product objects), footer_left, footer_right.

Creating a Custom Template

To create a custom invoice template, follow these steps:

1. Create a Blade File: Place your template in resources/views/vendor/rms-pdf (after publishing views). Use the elegant.blade.php template as a reference:
   • Structure your HTML with lang="fa" dir="rtl" for Persian support.
   • Use unicode-bidi: embed in CSS for proper text rendering.
   • Access data via $seller, $buyer, and $invoice objects (e.g., $seller->company, $invoice->products).
2. Style with CSS:
   • Use mPDF-compatible CSS properties like border, border-radius, flex, grid, padding, margin.
   • Avoid complex CSS (e.g., box-shadow, gradient) as mPDF has limited support.
   • Ensure font-family matches the configured font (e.g., Vazir or IRANSans) and direction: rtl for Persian text.
3. Publish the Template: If you add templates to the package source, they will be published with:

   php artisan vendor:publish --tag=rms-pdf-views

4. Set Default Theme: Update config/rms-pdf.php to use your custom template:

   'default_theme' => 'your-custom-theme',

Route Configuration

The package includes a test route in routes/pdf.php for development purposes. To use it, ensure your application's routes/web.php includes:

// routes/web.php
use RMS\PDF\Http\Controllers\PdfController;

Route::get('/rms-pdf-test', [PdfController::class, 'generate']);

Testing

To test the package:

1. Publish fonts, views, and configuration:

   php artisan vendor:publish --tag=rms-pdf-fonts
   php artisan vendor:publish --tag=rms-pdf-views
   php artisan vendor:publish --tag=rms-pdf-config

2. Visit /rms-pdf-test in your browser to download the PDF generated by the package's test controller (RMS\PDF\Http\Controllers\PdfController).
3. Verify that:
   • Persian text (e.g., "ریال", "فاکتور فروش") is rendered correctly with connected characters.
   • Styles (e.g., grid, flex, border, double, dotted, border-radius) are applied properly.
   • Data from Seller, Buyer, Bank, and Invoice classes is displayed correctly.

Troubleshooting

• Text Rendering Issues: Ensure the font files (e.g., Vazir.ttf, Vazir-Bold.ttf or IRANSans.ttf, IRANSans-Bold.ttf) are in public/vendor/rms-pdf/fonts and are from a reliable source (e.g., Vazir GitHub).
• Class Not Found Errors: Run composer dump-autoload in your project root to refresh the autoloader.
• Styling Issues: If styles like border-radius or grid don't render correctly, simplify the CSS or check mPDF documentation for supported properties.
