SwapURL Plugin (Under Development)

SwapURL is a WordPress plugin that allows administrators to replace specific URLs in post content based on a JSON file. This ensures that outdated links are updated efficiently across all posts.

Features

• [x] Admin interface for uploading JSON files containing old and new URLs.
• [ ] Automated processing via WP Cron to replace URLs in post content.
• [ ] Logging of successful replacements and errors.
• [ ] Secure file handling with nonce verification.
• [ ] Simple progress tracking.

Installation

1. Upload the swapurl plugin to the wp-content/plugins/ directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. Navigate to SwapURL in the WordPress admin menu.
4. Upload a JSON file containing URL mappings.

JSON File Format

The JSON file should be an array of objects, each containing:

[
    {
        "old_url": "https://old-url.com",
        "new_url": "https://new-url.com"
    },
    {
        "old_url": "https://another-old-url.com",
        "new_url": "https://another-new-url.com"
    }
]

How It Works

1. Upload a JSON file via the SwapURL admin page.
2. A cron job runs 15 seconds after the successful upload.
3. The plugin searches post_content in wp_posts and replaces old URLs with the new ones.
4. Logs are stored and displayed on the admin page.

Security & Validation

• Nonce verification prevents unauthorized uploads.
• Uploaded JSON files are validated to ensure they contain only to_replace and new_url keys.

Uninstallation

• Deactivating the plugin will stop processing but retain logs and settings.
• Manually delete uploaded JSON files from wp-content/json-files/ if necessary.
