WordPress文创商品柔性预售与社区团购插件集成教程

一、项目概述与需求分析

在文创电商领域，柔性预售和社区团购是两种极具潜力的商业模式。柔性预售允许商家根据订单量灵活安排生产，减少库存压力；社区团购则通过社交裂变实现低成本获客。本教程将指导您如何在WordPress中集成这两种功能。

核心需求：

1. 商品支持预售模式，可设置预售期限和最小起订量
2. 社区团购功能，支持团长管理和佣金结算
3. 用户友好的前台界面和后台管理
4. 与WooCommerce无缝集成

二、环境准备与插件规划

2.1 环境要求

<?php
/**
 * 检查系统环境要求
 * 需要PHP 7.4+、WordPress 5.6+、WooCommerce 4.0+
 */
function check_environment_requirements() {
    $errors = array();
    
    // 检查PHP版本
    if (version_compare(PHP_VERSION, '7.4.0', '<')) {
        $errors[] = '需要PHP 7.4或更高版本';
    }
    
    // 检查WordPress版本
    if (version_compare(get_bloginfo('version'), '5.6', '<')) {
        $errors[] = '需要WordPress 5.6或更高版本';
    }
    
    // 检查WooCommerce是否激活
    if (!class_exists('WooCommerce')) {
        $errors[] = '需要安装并激活WooCommerce插件';
    }
    
    return $errors;
}

// 执行环境检查
$env_errors = check_environment_requirements();
if (!empty($env_errors)) {
    foreach ($env_errors as $error) {
        echo '<div class="error"><p>' . esc_html($error) . '</p></div>';
    }
}
?>

2.2 插件结构规划

wp-content/plugins/cultural-presale-groupbuy/
├── assets/              # 静态资源
├── includes/            # 核心代码
│   ├── class-presale.php
│   ├── class-groupbuy.php
│   └── class-integration.php
├── templates/           # 模板文件
├── cultural-presale-groupbuy.php  # 主文件
└── uninstall.php        # 卸载脚本

三、预售功能开发实现

3.1 预售商品数据模型

<?php
/**
 * 预售商品自定义字段
 */
class Cultural_Presale_Product {
    
    /**
     * 初始化预售功能
     */
    public function init() {
        // 添加商品预售设置字段
        add_action('woocommerce_product_options_general_product_data', array($this, 'add_presale_fields'));
        add_action('woocommerce_process_product_meta', array($this, 'save_presale_fields'));
        
        // 修改商品显示
        add_filter('woocommerce_get_price_html', array($this, 'display_presale_price'), 10, 2);
    }
    
    /**
     * 添加预售设置字段到商品编辑页面
     */
    public function add_presale_fields() {
        global $product_object;
        
        echo '<div class="options_group presale-options">';
        
        // 预售开关
        woocommerce_wp_checkbox(array(
            'id'            => '_is_presale',
            'label'         => __('启用预售', 'cultural-presale'),
            'description'   => __('启用商品预售功能', 'cultural-presale'),
            'value'         => $product_object->get_meta('_is_presale', true),
        ));
        
        // 预售开始时间
        woocommerce_wp_text_input(array(
            'id'            => '_presale_start_date',
            'label'         => __('预售开始时间', 'cultural-presale'),
            'type'          => 'datetime-local',
            'value'         => $product_object->get_meta('_presale_start_date', true),
        ));
        
        // 预售结束时间
        woocommerce_wp_text_input(array(
            'id'            => '_presale_end_date',
            'label'         => __('预售结束时间', 'cultural-presale'),
            'type'          => 'datetime-local',
            'value'         => $product_object->get_meta('_presale_end_date', true),
        ));
        
        // 最小起订量
        woocommerce_wp_text_input(array(
            'id'            => '_presale_min_qty',
            'label'         => __('最小起订量', 'cultural-presale'),
            'type'          => 'number',
            'value'         => $product_object->get_meta('_presale_min_qty', true) ?: 10,
            'custom_attributes' => array('min' => '1'),
        ));
        
        // 预计发货时间
        woocommerce_wp_text_input(array(
            'id'            => '_estimated_delivery_date',
            'label'         => __('预计发货时间', 'cultural-presale'),
            'type'          => 'date',
            'value'         => $product_object->get_meta('_estimated_delivery_date', true),
        ));
        
        echo '</div>';
    }
    
    /**
     * 保存预售字段数据
     */
    public function save_presale_fields($product_id) {
        $product = wc_get_product($product_id);
        
        // 保存预售开关
        $is_presale = isset($_POST['_is_presale']) ? 'yes' : 'no';
        $product->update_meta_data('_is_presale', $is_presale);
        
        // 保存预售时间
        if (isset($_POST['_presale_start_date'])) {
            $product->update_meta_data('_presale_start_date', sanitize_text_field($_POST['_presale_start_date']));
        }
        
        if (isset($_POST['_presale_end_date'])) {
            $product->update_meta_data('_presale_end_date', sanitize_text_field($_POST['_presale_end_date']));
        }
        
        // 保存最小起订量
        if (isset($_POST['_presale_min_qty'])) {
            $product->update_meta_data('_presale_min_qty', absint($_POST['_presale_min_qty']));
        }
        
        // 保存预计发货时间
        if (isset($_POST['_estimated_delivery_date'])) {
            $product->update_meta_data('_estimated_delivery_date', sanitize_text_field($_POST['_estimated_delivery_date']));
        }
        
        $product->save();
    }
    
    /**
     * 显示预售价格信息
     */
    public function display_presale_price($price, $product) {
        if ($product->get_meta('_is_presale') === 'yes') {
            $end_date = $product->get_meta('_presale_end_date');
            $delivery_date = $product->get_meta('_estimated_delivery_date');
            
            if ($end_date) {
                $price .= '<div class="presale-badge">';
                $price .= '<span class="presale-label">' . __('预售商品', 'cultural-presale') . '</span>';
                $price .= '<span class="presale-end">' . sprintf(__('预售截止: %s', 'cultural-presale'), date('Y-m-d H:i', strtotime($end_date))) . '</span>';

            }
        }
        
        return $price;
    }
}

// 初始化预售功能
$presale_product = new Cultural_Presale_Product();
$presale_product->init();
?>

四、社区团购功能开发

4.1 团长管理与佣金系统

<?php
/**
 * 社区团购功能核心类
 */
class Cultural_Groupbuy {
    
    private $table_name;
    
    public function __construct() {
        global $wpdb;
        $this->table_name = $wpdb->prefix . 'cultural_groupbuy_leaders';
        
        // 初始化数据库表
        register_activation_hook(__FILE__, array($this, 'create_tables'));
        
        // 添加用户角色
        add_action('init', array($this, 'add_groupbuy_leader_role'));
        
        // 团长申请表单
        add_shortcode('groupbuy_leader_application', array($this, 'leader_application_form'));
    }
    
    /**
     * 创建团长数据表
     */
    public function create_tables() {
        global $wpdb;
        
        $charset_collate = $wpdb->get_charset_collate();
        
        $sql = "CREATE TABLE IF NOT EXISTS {$this->table_name} (
            id mediumint(9) NOT NULL AUTO_INCREMENT,

            wechat_id varchar(100),
            address text NOT NULL,
            status varchar(20) DEFAULT 'pending',
            commission_rate decimal(5,2) DEFAULT 10.00,
            total_commission decimal(10,2) DEFAULT 0.00,
            created_at datetime DEFAULT CURRENT_TIMESTAMP,

        dbDelta($sql);
    }
    
    /**

     */
    public function add_groupbuy_leader_role() {
        add_role('groupbuy_leader', __('社区团长', 'cultural-groupbuy'), array(
            'read' => true,
            'edit_posts' => false,
            'delete_posts' => false,
            'manage_groupbuy' => true,
        ));
    }
    
    /**
     * 团长申请表单短代码
     */
    public function leader_application_form() {

五、功能集成与前端展示

5.1 商品页面集成

<?php
