Key Features

​
Multi-Language Support

OpenCart supports multiple languages for your catalog content. Each product, category, and attribute can have descriptions in different languages. 
// Product descriptions are stored per language
$product_description = [
    1 => [ // English
        'name' => 'Product Name',
        'description' => 'Product description',
        'meta_title' => 'Product Meta Title'
    ],
    2 => [ // Spanish
        'name' => 'Nombre del Producto',
        'description' => 'Descripción del producto',
        'meta_title' => 'Título Meta del Producto'
    ]
];

​
Multi-Store Support

Manage products across multiple stores from a single admin panel. Each product can be assigned to specific stores.
Products must be explicitly assigned to stores. By default, new products are only available in the main store (store_id = 0).

​
SEO-Friendly URLs

Create custom SEO URLs for products and categories:
  • Products: https://yourstore.com/product-name
  • Categories: https://yourstore.com/category-name
  • Manufacturers: https://yourstore.com/brand-name
$product_seo_url = [
    0 => [ // Main store
        1 => 'laptop-computer', // English URL
        2 => 'ordenador-portatil' // Spanish URL
    ]
];

​
Catalog Filters

The catalog system includes powerful filtering capabilities:
  • Filter by name - Search products by name
  • Filter by model - Find products by model number
  • Filter by category - View products in specific categories
  • Filter by manufacturer - Show products from specific brands
  • Filter by price range - Set minimum and maximum prices
  • Filter by quantity - Find products by stock levels
  • Filter by status - Show enabled or disabled products
  • Filter by store - View products for specific stores
  • Filter by language - Filter by content language
Disabling a product will hide it from your storefront but preserve all product data. Use this feature instead of deleting products if you plan to re-enable them later.

​
Managing Catalog Data

​
Bulk Operations

Perform actions on multiple items simultaneously:
  • Enable/Disable - Toggle product or category status
  • Delete - Remove multiple items at once
  • Copy - Duplicate products with all settings

​
Data Export/Import

OpenCart supports exporting and importing catalog data through extensions and built-in tools. Always backup your data before performing bulk import operations.

​
