README

A Laravel package to generate context-aware placeholder content for your applications.

Installation

1. Install the package via Composer:

composer require halaabusalim/laravel-dynamic-placeholder

1. Publish the configuration file:

php artisan vendor:publish --provider="Halaabusalim\LaravelDynamicPlaceholder\DynamicPlaceholderServiceProvider" --tag="config"

Usage

Using the Facade

use Halaabusalim\LaravelDynamicPlaceholder\Facades\DynamicPlaceholder;

// Generate text placeholders
$productName = DynamicPlaceholder::text('ecommerce.product_name');
$blogTitle = DynamicPlaceholder::text('blog.title');

// Generate number placeholders
$price = DynamicPlaceholder::number('ecommerce.price');

// Generate image placeholders
$imageUrl = DynamicPlaceholder::image('product-image');

Using Dependency Injection

use Halaabusalim\LaravelDynamicPlaceholder\DynamicPlaceholder;

class ProductController extends Controller
{
    public function __construct(private DynamicPlaceholder $placeholder)
    {
    }

    public function index()
    {
        $productName = $this->placeholder->text('ecommerce.product_name');
        $price = $this->placeholder->number('ecommerce.price');
        
        return view('products.index', compact('productName', 'price'));
    }
}

Configuration

The package comes with a configuration file that you can customize. Edit config/dynamic-placeholder.php:

return [
    'contexts' => [
        'ecommerce' => [
            'product_name' => ['Laptop', 'Smartphone', 'Headphones', 'Smartwatch'],
            'description' => [
                'High-performance device for professionals.',
                'Sleek design with cutting-edge technology.',
                'Perfect for everyday use.'
            ],
            'price' => ['min' => 50, 'max' => 1000],
        ],
        'blog' => [
            'title' => ['Top 10 Tips for Success', 'How to Start a Blog', 'The Future of Tech'],
