Step 2: Automated Content Enrichment and Sanitization Engine

Create a custom plugin or add the following production-ready code to your theme’s `functions.php` file. This snippet hooks into the post-transition event, intercepts new directory submissions, cleans input data against XSS vectors, and dispatches a structured prompt to OpenAI to generate optimized meta descriptions and clean business summaries.

 * Plugin Name: SiteSuraksha Directory AI Accelerator
 * Description: Automates business listing enrichment and taxonomy mapping securely.
 * Version: 1.0.0

Step 3: WP-CLI Batch Processing Automation

For existing directories containing thousands of legacy listings, running real-time updates upon publish is insufficient. Utilize WP-CLI to execute asynchronous batch processing scripts via SSH, preventing PHP timeout errors during mass enrichment.

# Create a custom WP-CLI command or run an iterative batch loop via bash
wp eval '
$posts = get_posts([
    "post_type"      => "business_listing",
    "posts_per_page" => 50,
    "meta_query"     => [
        [
            "key"     => "_sitesuraksha_ai_description",
            "compare" => "NOT EXISTS"
        ]
    ]
]);

foreach ( $posts as $post ) {
    WP_CLI::line( "Processing Listing ID: " . $post->ID );
    // Trigger enrichment function logic here
}
