WordPress文创数字藏品柔性发行与管理插件开发教程

WordPress文创数字藏品柔性发行与管理插件开发教程

一、项目概述与需求分析

在数字文创产业蓬勃发展的今天，数字藏品作为文化创意产品的新形态，正受到越来越多创作者和收藏家的青睐。本教程将指导您开发一个WordPress插件，实现文创数字藏品的柔性发行与管理功能。

核心需求分析：

支持数字藏品的创建、编辑和分类管理
实现灵活的发行策略（限量发行、定时发行、分阶段发行）
集成区块链元数据记录（模拟实现）
提供用户收藏、展示和交易功能
确保数据安全和权限控制

二、开发环境搭建与插件基础结构

首先，我们需要创建插件的基本结构。在WordPress的wp-content/plugins/目录下创建新文件夹digital-collections。

<?php
/**
 * Plugin Name: 文创数字藏品管理系统
 * Plugin URI: https://yourwebsite.com/
 * Description: WordPress文创数字藏品柔性发行与管理插件
 * Version: 1.0.0
 * Author: 您的名称
 * License: GPL v2 or later
 * Text Domain: digital-collections
 */

// 防止直接访问
if (!defined('ABSPATH')) {
    exit;
}

// 定义插件常量
define('DC_VERSION', '1.0.0');
define('DC_PLUGIN_DIR', plugin_dir_path(__FILE__));
define('DC_PLUGIN_URL', plugin_dir_url(__FILE__));

// 初始化插件
class DigitalCollections {
    
    private static $instance = null;
    
    public static function get_instance() {
        if (null === self::$instance) {
            self::$instance = new self();
        }
        return self::$instance;
    }
    
    private function __construct() {
        $this->init_hooks();
    }
    
    private function init_hooks() {
        // 激活/停用插件时的操作
        register_activation_hook(__FILE__, array($this, 'activate'));
        register_deactivation_hook(__FILE__, array($this, 'deactivate'));
        
        // 初始化
        add_action('init', array($this, 'init'));
        
        // 管理菜单
        add_action('admin_menu', array($this, 'add_admin_menu'));
        
        // 加载脚本和样式
        add_action('admin_enqueue_scripts', array($this, 'enqueue_admin_scripts'));
        add_action('wp_enqueue_scripts', array($this, 'enqueue_frontend_scripts'));
    }
    
    public function activate() {
        // 创建必要的数据库表
        $this->create_tables();
        
        // 刷新重写规则
        flush_rewrite_rules();
    }
    
    public function deactivate() {
        // 清理临时数据
        flush_rewrite_rules();
    }
    
    public function init() {
        // 注册自定义文章类型
        $this->register_post_types();
        
        // 注册短代码
        $this->register_shortcodes();
        
        // 加载文本域
        load_plugin_textdomain('digital-collections', false, dirname(plugin_basename(__FILE__)) . '/languages');
    }
    
    // 其他方法将在后续部分实现
}

// 启动插件
DigitalCollections::get_instance();
?>

三、自定义文章类型与分类系统

数字藏品需要自定义的文章类型来存储和管理。我们将创建digital_collection文章类型和相应的分类法。

// 在DigitalCollections类中添加以下方法

/**
 * 注册数字藏品自定义文章类型
 */
public function register_post_types() {
    // 数字藏品主类型
    $labels = array(
        'name'               => __('数字藏品', 'digital-collections'),
        'singular_name'      => __('数字藏品', 'digital-collections'),
        'menu_name'          => __('数字藏品', 'digital-collections'),
        'add_new'            => __('添加新藏品', 'digital-collections'),
        'add_new_item'       => __('添加新数字藏品', 'digital-collections'),
        'edit_item'          => __('编辑数字藏品', 'digital-collections'),
        'new_item'           => __('新数字藏品', 'digital-collections'),
        'view_item'          => __('查看数字藏品', 'digital-collections'),
        'search_items'       => __('搜索数字藏品', 'digital-collections'),
        'not_found'          => __('未找到数字藏品', 'digital-collections'),
        'not_found_in_trash' => __('回收站中未找到数字藏品', 'digital-collections'),
    );
    
    $args = array(
        'labels'             => $labels,
        'public'             => true,
        'publicly_queryable' => true,
        'show_ui'            => true,
        'show_in_menu'       => true,
        'query_var'          => true,
        'rewrite'            => array('slug' => 'collection'),
        'capability_type'    => 'post',
        'has_archive'        => true,
        'hierarchical'       => false,
        'menu_position'      => 5,
        'menu_icon'          => 'dashicons-format-image',
        'supports'           => array('title', 'editor', 'thumbnail', 'excerpt', 'comments'),
        'show_in_rest'       => true, // 支持Gutenberg编辑器
    );
    
    register_post_type('digital_collection', $args);
    
    // 注册数字藏品分类
    $category_labels = array(
        'name'              => __('藏品分类', 'digital-collections'),
        'singular_name'     => __('藏品分类', 'digital-collections'),
        'search_items'      => __('搜索分类', 'digital-collections'),
        'all_items'         => __('所有分类', 'digital-collections'),
        'parent_item'       => __('父分类', 'digital-collections'),
        'parent_item_colon' => __('父分类:', 'digital-collections'),
        'edit_item'         => __('编辑分类', 'digital-collections'),
        'update_item'       => __('更新分类', 'digital-collections'),
        'add_new_item'      => __('添加新分类', 'digital-collections'),
        'new_item_name'     => __('新分类名称', 'digital-collections'),
        'menu_name'         => __('藏品分类', 'digital-collections'),
    );
    
    $category_args = array(
        'hierarchical'      => true,
        'labels'            => $category_labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'query_var'         => true,
        'rewrite'           => array('slug' => 'collection-category'),
        'show_in_rest'      => true,
    );
    
    register_taxonomy('collection_category', array('digital_collection'), $category_args);
    
    // 注册创作者分类法
    $creator_labels = array(
        'name'              => __('创作者', 'digital-collections'),
        'singular_name'     => __('创作者', 'digital-collections'),
        'search_items'      => __('搜索创作者', 'digital-collections'),
        'all_items'         => __('所有创作者', 'digital-collections'),
        'edit_item'         => __('编辑创作者', 'digital-collections'),
        'update_item'       => __('更新创作者', 'digital-collections'),
        'add_new_item'      => __('添加新创作者', 'digital-collections'),
        'new_item_name'     => __('新创作者名称', 'digital-collections'),
        'menu_name'         => __('创作者', 'digital-collections'),
    );
    
    $creator_args = array(
        'hierarchical'      => false,
        'labels'            => $creator_labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'query_var'         => true,
        'rewrite'           => array('slug' => 'collection-creator'),
        'show_in_rest'      => true,
    );
    
    register_taxonomy('collection_creator', array('digital_collection'), $creator_args);
}

四、元数据管理与发行策略

数字藏品需要存储额外的元数据，如发行数量、发行时间、区块链信息等。我们将创建自定义元字段和发行策略管理。

// 在DigitalCollections类中添加以下方法

/**
 * 添加数字藏品元数据框
 */
public function add_meta_boxes() {
    add_meta_box(
        'digital_collection_meta',
        __('藏品发行信息', 'digital-collections'),
        array($this, 'render_meta_box'),
        'digital_collection',
        'normal',
        'high'
    );
}

/**
 * 渲染元数据框内容
 */
public function render_meta_box($post) {
    // 添加安全验证
    wp_nonce_field('digital_collection_meta_box', 'digital_collection_meta_box_nonce');
    
    // 获取现有值
    $total_supply = get_post_meta($post->ID, '_dc_total_supply', true);
    $minted_count = get_post_meta($post->ID, '_dc_minted_count', true) ?: 0;
    $price = get_post_meta($post->ID, '_dc_price', true);
    $release_date = get_post_meta($post->ID, '_dc_release_date', true);
    $release_type = get_post_meta($post->ID, '_dc_release_type', true) ?: 'immediate';
    $blockchain_hash = get_post_meta($post->ID, '_dc_blockchain_hash', true);
    $contract_address = get_post_meta($post->ID, '_dc_contract_address', true);
    
    // 发行类型选项
    $release_types = array(
        'immediate' => __('立即发行', 'digital-collections'),
        'scheduled' => __('定时发行', 'digital-collections'),
        'phased'    => __('分阶段发行', 'digital-collections'),
        'auction'   => __('拍卖发行', 'digital-collections'),
    );
    
    ?>
    <div class="dc-meta-box">
        <table class="form-table">
            <tr>
                <th><label for="dc_total_supply"><?php _e('发行总量', 'digital-collections'); ?></label></th>
                <td>
                    <input type="number" id="dc_total_supply" name="dc_total_supply" 
                           value="<?php echo esc_attr($total_supply); ?>" min="1" max="100000" />
                    <p class="description"><?php _e('该藏品的总发行数量', 'digital-collections'); ?></p>
                </td>
            </tr>
            <tr>
                <th><label for="dc_minted_count"><?php _e('已铸造数量', 'digital-collections'); ?></label></th>

    <script>
    jQuery(document).ready(function($) {
        // 显示/隐藏发行时间字段
        $('#dc_release_type').change(function() {
            if ($(this).val() === 'scheduled') {

public function save_meta_box($post_id) {
    // 安全检查
    if (!isset($_POST['digital_collection_meta_box_nonce']) ||
        !wp_verify_nonce($_POST['digital_collection_meta_box_nonce'], 'digital_collection_meta_box')) {

add_action('add_meta_boxes', array($this, 'add_meta_boxes'));
add_action('save_post_digital_collection', array($this, 'save_meta_box'));

五、用户收藏与交易系统

创建用户收藏功能和简单的交易记录系统。

// 创建用户收藏功能
class DC_User_Collections {
    
    /**
     * 用户收藏藏品
     */
    public static function add_to_collection($user_id, $collection_id) {

            return new WP_Error('invalid_collection', __('无效的藏品', 'digital-collections'));
        }
        
        // 检查发行限制
        $total_supply = get_post_meta($collection_id, '_dc_total_supply', true);
        $minted_count = get_post_meta($collection_id, '_dc_minted_count', true) ?: 0;

            return new WP_Error('sold_out', __('该藏品已售罄', 'digital-collections'));
        }
        
        // 创建收藏记录
        $result = $wpdb->insert(
            $table_name,
            array(

        if ($result) {
            // 更新已铸造数量
            update_post_meta($collection_id, '_dc_minted_count', $minted_count + 1);
            
            // 记录交易
            self::record_transaction($user_id, $collection_id, 'purchase');

创建前端展示功能和短代码，让用户可以在网站任何位置展示数字藏品。

// 在DigitalCollections类中添加短代码功能

/**

注册短代码

// 用户收藏展示短代码
add_shortcode('my_collections', array($this, 'my_collections_shortcode'));

// 最新藏品短代码
add_shortcode('latest_collections', array($this, 'latest_collections_shortcode'));

}

藏品展示短代码
*/

    'limit' => 12,
    'columns' => 3,

// 构建查询参数
$args = array(
    'post_type' => 'digital_collection',
    'posts_per_page' => intval($atts['limit']),

// 添加分类筛选

        'taxonomy' => 'collection_category',
        'field' => 'slug',
        'terms' => explode(',', $atts['category'])
    );
}

// 添加创作者筛选
if (!empty($atts['creator'])) {
