AutoGrid – Make Model Year

AutoGrid – Make Model Year is a lightweight yet powerful plugin that lets you store, manage, search, and export vehicle data (Make → Model → Year) directly from your WordPress dashboard.

Key Features

• Custom database table for high-performance storage
• Add, edit, and delete car Makes, Models, and Years
• Bulk Export to CSV — handles 100,000+ records using chunked streaming (no PHP memory limit issues)
• Bulk Import via CSV — import large datasets with batch processing
• Search and filter from the admin list view
• Pagination for large datasets
• REST API endpoints for headless and external access
• Shortcode to display a vehicle selector on the frontend
• WP-CLI commands for server-side operations
• Compatible with WordPress Multisite
• No external dependencies — pure WordPress APIs

How It Works

The plugin creates a dedicated database table with proper indexes for fast queries, even with 1,000,000+ rows. Export uses PHP output buffering with chunked streaming so it never loads all records into memory. Import processes rows in configurable batches for reliability.

Shortcode

Display a cascading vehicle selector on any page:

[car_selector]

Optional attributes:

[car_selector show_year="true" show_search="true" redirect="/results/"]
