title: "[FEATURE] Batch Processing — Generate OG Tags for All Existing Articles"
labels: "enhancement, priority: high"
milestone: "v01.01"
---

## Feature Description
Add batch processing capability to generate or regenerate Open Graph tags for all existing articles in bulk, rather than requiring manual editing of each article.

## Problem or Use Case
When MokoOpenGraph is installed on an existing site with hundreds of articles, each article needs OG tags. Manually editing each one is impractical. Tagz Pro offers this as a premium feature — we should include it in the base package.

## Proposed Solution
Add a "Batch Generate" toolbar button to the com_mokoog admin view that:
1. Scans all published articles in `#__content`
2. For each article without existing OG data in `#__mokoog_tags`, auto-generates:
   - `og_title` from article title
   - `og_description` from meta description or intro text (first 160 chars)
   - `og_image` from full-text image or intro image
3. Shows a progress bar during processing
4. Reports how many records were created/skipped

## Implementation Details
- New `Controller/BatchController.php` with `generate()` action
- New `Model/BatchModel.php` for bulk operations
- AJAX endpoint for progress reporting (avoid PHP timeout on large sites)
- Process in chunks of 50 articles per request
- Add batch button to `View/Tags/HtmlView.php` toolbar
