Extensibility

The plugin is built with extensibility in mind. Here are the key hooks:

Actions

// Before content generation starts
do_action('demo_content_before_generation', $subject, $post_types, $items_per_type);

// After content generation completes
do_action('demo_content_after_generation', $results, $subject, $post_types);

// After a single post is created
do_action('demo_content_post_created', $post_id, $post_type, $content_data);

// When plugin is loaded
do_action('demo_content_loaded');

Filters

// Modify available post types
apply_filters('demo_content_available_post_types', $post_types);

// Customize OpenAI text generation parameters
apply_filters('demo_content_openai_text_params', $data, $prompt, $model);

// Customize OpenAI image generation parameters
apply_filters('demo_content_openai_image_params', $data, $prompt, $size);

// Modify title generation prompt
apply_filters('demo_content_title_prompt', $prompt, $subject, $post_type, $item_number);

// Modify content generation prompt
apply_filters('demo_content_content_prompt', $prompt, $subject, $post_type, $title);

// Modify image generation prompt
apply_filters('demo_content_image_prompt', $image_prompt, $subject, $title);

// Filter generated content before creating post
apply_filters('demo_content_generated_item', $data, $subject, $post_type, $item_number);

// Filter post data before wp_insert_post
apply_filters('demo_content_post_data', $post_data, $post_type, $content_data);

// Enable/disable image generation
apply_filters('demo_content_enable_image_generation', true, $subject, $title);

// Custom handler for specific post types
apply_filters('demo_content_custom_post_type_handler', null, $post_type, $subject, $items_per_type, $openai);

// Customize post type icon in admin
apply_filters('demo_content_post_type_icon', $icon, $post_type);

Creating Add-ons

Add-ons can extend the plugin to support additional post types or features. Here's an example:

<?php
/**
 * Plugin Name: Demo Content - WooCommerce Products
 * Description: Generate WooCommerce products with Demo Content Generator
 */

// Handle WooCommerce product generation
add_filter('demo_content_custom_post_type_handler', function($handler, $post_type, $subject, $items_per_type, $openai) {
    if ($post_type === 'product') {
        $products = array();

        for ($i = 0; $i < $items_per_type; $i++) {
            // Your custom product generation logic here
            $product_id = create_woocommerce_product($openai, $subject, $i);
            $products[] = array(
                'id' => $product_id,
                'title' => get_the_title($product_id)
            );
        }

        return $products;
    }

    return $handler;
}, 10, 5);

Cost Considerations

• GPT-4o-mini: ~$0.15 per 1M input tokens, ~$0.60 per 1M output tokens
• DALL-E 3: ~$0.04 per standard quality 1024x1024 image
