Automatic images of opencart categories

Automatic category images help streamline product category image management: when there are empty category images in the database, the system automatically inserts suitable images from related products and child sections. This results in a more vibrant storefront, and helps users find what they're looking for faster.

Why do you need a module?

In practice, this often happens: a category is created, but the image field is empty. Customers see uniform placeholders or empty blocks, and they have to manually move images in the admin panel. This module takes care of this: it searches for products and subcategories with images and moves them to the appropriate categories.

What the module does (main functions)

The mechanics are built around selecting and updating the OpenCart database. After applying the module, a series of operations are performed: first, images are "cleaned" where they are missing, then images are selected from products and nested categories.

Update operations and logic

• Clearing empty values: empty lines are inserted where the image field is NULL (for categories and products).
• Collecting categories without images: the module finds categories with image = ''.
• Checking product links: for each such category, linked products are selected from the product_to_category table.
• Search for product images: if a product has an image, it is moved to the category.
• Multi-level structure support: additionally, categories' nesting levels are iterated over to pull images from child sections when possible.

Important: The module populates the image field for categories based on available images for related products and subsections. If a category truly doesn't have a product with an image or child categories with images, the update won't occur.
