WordPress文创插件开发：柔性产品生命周期分析模块教程

引言：文创产品与生命周期管理

在当今数字化文创产业中，产品生命周期管理变得日益重要。文创产品（如数字艺术品、文创衍生品、文化IP产品等）通常具有非标准化的特性，其生命周期受到市场需求、文化趋势、季节因素等多重影响。本教程将指导您开发一个WordPress插件，专门用于分析和管理文创产品的柔性生命周期。

通过这个插件，文创企业可以：

• 追踪产品从概念到退市的完整周期
• 分析不同文创产品的市场表现
• 预测产品生命周期阶段并制定相应策略
• 可视化展示产品生命周期数据

环境准备与插件基础结构

首先，我们需要创建插件的基本文件结构：

<?php
/**
 * Plugin Name: 文创产品生命周期分析
 * Plugin URI: https://yourwebsite.com/
 * Description: 用于分析和管理文创产品柔性生命周期的WordPress插件
 * Version: 1.0.0
 * Author: 您的名称
 * License: GPL v2 or later
 */

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

// 定义插件常量
define('CPLA_VERSION', '1.0.0');
define('CPLA_PLUGIN_DIR', plugin_dir_path(__FILE__));
define('CPLA_PLUGIN_URL', plugin_dir_url(__FILE__));

// 初始化插件
require_once CPLA_PLUGIN_DIR . 'includes/class-core.php';

// 插件激活时的操作
register_activation_hook(__FILE__, 'cpla_activate_plugin');
function cpla_activate_plugin() {
    require_once CPLA_PLUGIN_DIR . 'includes/class-activator.php';
    CPLA_Activator::activate();
}

// 插件停用时的操作
register_deactivation_hook(__FILE__, 'cpla_deactivate_plugin');
function cpla_deactivate_plugin() {
    require_once CPLA_PLUGIN_DIR . 'includes/class-deactivator.php';
    CPLA_Deactivator::deactivate();
}
?>

数据库设计与产品数据模型

文创产品生命周期分析需要存储产品信息、销售数据和生命周期阶段。以下是数据库表的设计：

<?php
// 文件路径：includes/class-activator.php

class CPLA_Activator {
    public static function activate() {
        global $wpdb;
        $charset_collate = $wpdb->get_charset_collate();
        
        // 文创产品表
        $table_products = $wpdb->prefix . 'cpla_products';
        $sql_products = "CREATE TABLE IF NOT EXISTS $table_products (
            id mediumint(9) NOT NULL AUTO_INCREMENT,

        ) $charset_collate;";
        
        // 产品销售数据表
        $table_sales = $wpdb->prefix . 'cpla_sales_data';
        $sql_sales = "CREATE TABLE IF NOT EXISTS $table_sales (

        // 生命周期阶段定义表
        $table_stages = $wpdb->prefix . 'cpla_lifecycle_stages';
        $sql_stages = "CREATE TABLE IF NOT EXISTS $table_stages (

            stage_order int(11) NOT NULL COMMENT '阶段顺序',

        require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
        dbDelta($sql_products);

        dbDelta($sql_stages);
        
        // 插入默认的生命周期阶段数据
        self::insert_default_stages();
    }
    
    private static function insert_default_stages() {
        global $wpdb;
        $table_stages = $wpdb->prefix . 'cpla_lifecycle_stages';
        
        $default_stages = array(
            array('stage_name' => '概念期', 'stage_order' => 1, 'min_duration' => 30, 'color_code' => '#95a5a6'),
            array('stage_name' => '开发期', 'stage_order' => 2, 'min_duration' => 60, 'color_code' => '#3498db'),

核心功能：生命周期分析算法

柔性产品生命周期分析的核心是根据销售数据和产品特征动态判断产品所处的生命周期阶段：
