WordPress文创项目柔性众筹插件开发详解
一、项目背景与需求分析
随着文创产业的蓬勃发展，越来越多的创作者需要灵活的资金支持方式。传统的众筹平台往往采用"全有或全无"的固定模式，缺乏灵活性。为此，我们开发了一款WordPress柔性众筹插件，允许创作者设置弹性目标，按实际筹集金额比例交付回报。
核心需求：
- 支持弹性目标设置（最低目标、理想目标、超额目标）
- 多种支付方式集成（支付宝、微信支付、银行卡）
- 多级回报体系
- 实时进度展示
- 后台管理界面
- 数据统计与分析
二、插件架构设计
2.1 数据库设计
<?php

*/
function flexible_crowdfunding_create_tables() {
global $wpdb;
$charset_collate = $wpdb->get_charset_collate();
$table_prefix = $wpdb->prefix . 'fc_';
// 项目表
$projects_table = $table_prefix . 'projects';
$projects_sql = "CREATE TABLE IF NOT EXISTS $projects_table (

// 支持记录表
$backers_table = $table_prefix . 'backers';
$backers_sql = "CREATE TABLE IF NOT EXISTS $backers_table (

INDEX idx_status (status)

// 回报等级表
$rewards_table = $table_prefix . 'rewards';
$rewards_sql = "CREATE TABLE IF NOT EXISTS $rewards_table (
id INT(11) NOT NULL AUTO_INCREMENT,
