WordPress文创产品柔性限时预售插件开发实战教程
一、项目概述与需求分析
在文创产品销售领域，柔性预售模式越来越受欢迎。这种模式允许商家根据预售情况调整生产数量，降低库存风险。本教程将带领大家开发一个完整的WordPress文创产品柔性限时预售插件。
核心功能需求：
- 为产品添加预售状态和预售时间设置
- 显示预售倒计时和预售进度
- 支持预售数量限制和柔性调整
- 预售结束后自动转为正常销售或下架
- 后台管理界面和销售数据统计
二、插件基础结构搭建
首先创建插件的基本目录结构和主文件：
<?php
/**
* Plugin Name: 文创产品柔性限时预售插件
* Plugin URI: https://yourwebsite.com/
* Description: 为WordPress文创产品添加柔性限时预售功能
* Version: 1.0.0
* Author: 你的名字
* License: GPL v2 or later
* Text Domain: flexible-presale
*/
// 防止直接访问
if (!defined('ABSPATH')) {
exit;
}
// 定义插件常量
define('FLEXIBLE_PRESALE_VERSION', '1.0.0');
define('FLEXIBLE_PRESALE_PATH', plugin_dir_path(__FILE__));
define('FLEXIBLE_PRESALE_URL', plugin_dir_url(__FILE__));
// 初始化插件
class Flexible_Presale_Plugin {
private static $instance = null;
public static function get_instance() {
if (null === self::$instance) {
self::$instance = new self();
}
return self::$instance;
}
private function __construct() {
$this->init_hooks();
}
private function init_hooks() {
// 激活/停用钩子
register_activation_hook(__FILE__, array($this, 'activate'));
register_deactivation_hook(__FILE__, array($this, 'deactivate'));
// 初始化
add_action('plugins_loaded', array($this, 'init'));
}
public function activate() {
// 创建必要的数据库表
$this->create_tables();
// 设置默认选项
update_option('flexible_presale_version', FLEXIBLE_PRESALE_VERSION);
}
public function deactivate() {
// 清理临时数据
wp_clear_scheduled_hook('flexible_presale_daily_check');
}
public function init() {
// 加载文本域
load_plugin_textdomain('flexible-presale', false, dirname(plugin_basename(__FILE__)) . '/languages');
// 包含必要文件
$this->includes();
// 初始化组件
$this->init_components();
}
private function includes() {
// 包含后台管理类
require_once FLEXIBLE_PRESALE_PATH . 'includes/class-admin.php';
// 包含产品管理类
require_once FLEXIBLE_PRESALE_PATH . 'includes/class-product.php';
// 包含前端显示类
require_once FLEXIBLE_PRESALE_PATH . 'includes/class-frontend.php';
// 包含AJAX处理类
require_once FLEXIBLE_PRESALE_PATH . 'includes/class-ajax.php';
}
private function init_components() {
// 初始化各个组件
Flexible_Presale_Admin::init();
Flexible_Presale_Product::init();
Flexible_Presale_Frontend::init();
Flexible_Presale_Ajax::init();
}
private function create_tables() {
global $wpdb;
$charset_collate = $wpdb->get_charset_collate();
$table_name = $wpdb->prefix . 'flexible_presale_data';
$sql = "CREATE TABLE IF NOT EXISTS $table_name (

require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
dbDelta($sql);
}
}
// 启动插件
Flexible_Presale_Plugin::get_instance();
?>三、产品预售数据管理模块
接下来创建产品管理类，用于处理产品的预售设置：
<?php
/**
* 产品预售管理类
*/
class Flexible_Presale_Product {
public static function init() {
// 添加产品预售设置字段
add_action('woocommerce_product_options_general_product_data', array(__CLASS__, 'add_presale_fields'));

// 添加预售状态到产品列表
add_filter('manage_product_posts_columns', array(__CLASS__, 'add_presale_column'));
add_action('manage_product_posts_custom_column', array(__CLASS__, 'show_presale_column'), 10, 2);
}
/**
* 在产品编辑页面添加预售设置字段
*/
public static function add_presale_fields() {

echo '</div>';
// 添加JavaScript处理日期时间选择器
self::add_admin_scripts();
}
/**
* 保存产品预售设置
*/
public static function save_presale_fields($post_id) {
// 验证nonce
if (!isset($_POST['woocommerce_meta_nonce']) ||

return;
}
// 保存预售设置
$is_presale = isset($_POST['_is_presale']) ? 'yes' : 'no';

}
}
/**

*/
private static function add_admin_scripts() {
?>
<script type="text/javascript">
jQuery(document).ready(function($) {

<?php
}
}
?>四、前端预售展示与倒计时功能
创建前端显示类，处理产品页面的预售信息展示：
<?php
/**

if (!self::is_presale_product($product->get_id())) {
return;
}
$product_id = $product->get_id();
$presale_data = self::get_presale_data($product_id);

<?php
$current_qty = $presale_data->current_quantity;
$target_qty = $presale_data->target_quantity;
$percentage = $target_qty > 0 ? min(100, ($current_qty / $target_qty) * 100) : 0;
?>
<div class="progress-bar">
<div class="progress-fill" style="width: <?php echo $percentage; ?>%"></div>
</div>
<p class="progress-text">

<?php if ($presale_data->is_flexible) : ?>
<?php _e('✅ 此为柔性预售：最终生产数量将根据预售情况调整', 'flexible-presale'); ?>
<?php else : ?>
<?php _e('📦 此为定量预售：达到目标数量即开始生产', 'flexible-presale'); ?>
<?php endif; ?>
</p>
<p>
<?php _e('⏰ 预售结束后将根据订单安排生产，预计发货时间将另行通知', 'flexible-presale'); ?>
</p>
</div>
</div>
<script type="text/javascript">
jQuery(document).ready(function($) {
// 初始化倒计时
initializeCountdown(<?php echo $product_id; ?>, '<?php echo $presale_data->presale_end; ?>');
});
</script>
<?php
}
/**
* 在商品列表显示预售标签
*/
public static function add_presale_badge() {

*/
public static function enqueue_frontend_scripts() {

return $wpdb->get_row($wpdb->prepare(
"SELECT * FROM $table_name WHERE product_id = %d AND status = 'active'",
$product_id
));
}}
?>
## 五、倒计时与预售进度JavaScript实现
创建倒计时JavaScript文件：
/**
- 预售倒计时功能
*/
(function($) {
'use strict';
// 倒计时计时器集合
var countdownTimers = {};
/**
* 初始化倒计时
*/
window.initializeCountdown = function(productId, endDateStr) {
var endDate = new Date(endDateStr);
var countdownElement = $('#presale-countdown-' + productId);
if (!countdownElement.length || isNaN(endDate.getTime())) {
return;
}
// 更新倒计时显示
function updateCountdown() {
var now = new Date();
var timeLeft = endDate - now;
if (timeLeft <= 0) {
clearInterval(countdownTimers[productId]);
countdownElement.html('<div class="countdown-ended">预售已结束</div>');
updatePresaleStatus(productId);
return;
}
var days = Math.floor(timeLeft / (1000 * 60 * 60 * 24));
var hours = Math.floor((timeLeft % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((timeLeft % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((timeLeft % (1000 * 60)) / 1000);
var countdownHtml = '<div class="countdown-digits">';
countdownHtml += '<div class="countdown-unit"><span class="digit">' + days + '</span><span class="label">天</span></div>';
countdownHtml += '<div class="countdown-unit"><span class="digit">' + hours + '</span><span class="label">时</span></div>';
countdownHtml += '<div class="countdown-unit"><span class="digit">' + minutes + '</span><span class="label">分</span></div>';
countdownHtml += '<div class="countdown-unit"><span class="digit">' + seconds + '</span><span class="label">秒</span></div>';
countdownHtml += '</div>';
countdownElement.html(countdownHtml);
}
// 立即更新一次
updateCountdown();
// 每秒更新一次
countdownTimers[productId] = setInterval(updateCountdown, 1000);
};
/**
* 更新预售状态
*/
function updatePresaleStatus(productId) {
$.ajax({
url: presale_vars.ajax_url,
type: 'POST',
data: {
action: 'update_presale_status',
product_id: productId,
nonce: presale_vars.nonce
},
success: function(response) {
if (response.success) {
// 刷新页面或更新UI
location.reload();
}
}
});
}
/**
* 更新预售进度
*/
window.updatePresaleProgress = function(productId, quantity) {
$.ajax({
url: presale_vars.ajax_url,
type: 'POST',
data: {
action: 'update_presale_progress',
product_id: productId,
quantity: quantity,
nonce: presale_vars.nonce
},
success: function(response) {
if (response.success) {
// 更新进度条显示
var percentage = response.data.percentage;
$('.progress-fill').css('width', percentage + '%');
$('.progress-text').text('已预售 ' + response.data.current + ' / 目标 ' + response.data.target + ' (' + percentage.toFixed(1) + '%)');
}
}
});
};
/**
* 页面加载完成后初始化所有倒计时
*/
$(document).ready(function() {
$('[id^="presale-countdown-"]').each(function() {
var id = $(this).attr('id');
var productId = id.replace('presale-countdown-', '');
var endDate = $(this).data('end-date');
if (productId && endDate) {
initializeCountdown(productId, endDate);
}
});
// 监听加入购物车事件
$(document).on('added_to_cart', function(e, fragments, cart_hash, $button) {
var productId = $button.data('product_id');
var quantity = $button.data('quantity') || 1;
if (productId) {
updatePresaleProgress(productId, quantity);
}
});
});
})(jQuery);
## 六、AJAX处理与后台管理
创建AJAX处理类：
<?php
/**
- AJAX处理类
*/
class Flexible_Presale_Ajax {
public static function init() {
// 更新预售状态
add_action('wp_ajax_update_presale_status', array(__CLASS__, 'update_presale_status'));

// 更新预售进度
add_action('wp_ajax_update_presale_progress', array(__CLASS__, 'update_presale_progress'));
add_action('wp_ajax_nopriv_update_presale_progress', array(__CLASS__, 'update_presale_progress'));
// 获取预售统计数据
add_action('wp_ajax_get_presale_stats', array(__CLASS__, 'get_presale_stats'));
// 每日检查预售状态
add_action('flexible_presale_daily_check', array(__CLASS__, 'daily_status_check'));
}
/**
* 更新预售状态
*/
public static function update_presale_status() {
// 验证nonce
if (!wp_verify_nonce($_POST['nonce'], 'flexible_presale_nonce')) {
wp_die('权限验证失败');
}
$product_id = intval($_POST['product_id']);

);
// 发送邮件通知
self::send_presale_end_notification($product_id);
wp_send_json_success(array(

$quantity = intval($_POST['quantity']);
if ($product_id && $quantity > 0) {

: 0;
// 检查是否达到目标
if ($new_quantity >= $current_data->target_quantity && $current_data->target_quantity > 0) {
self::handle_target_reached($product_id, $current_data);
}
wp_send_json_success(array(

## 七、CSS样式设计与优化
创建前端样式文件：
/ 预售插件前端样式 /
.flexible-presale-info {
background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
border-radius: 10px;
padding: 25px;
margin-bottom: 30px;
color: white;
box-shadow: 0 10px 30px rgba(0, 0, 0, 0.1);}
.presale-header h3 {
margin: 0 0 10px 0;
font-size: 24px;
font-weight: bold;}
.presale-description {
margin: 0 0 20px 0;
opacity: 0.9;
font-size: 14px;}
/ 倒计时样式 /
.presale-countdown {
margin: 25px 0;
padding: 20px;
background: rgba(255, 255, 255, 0.1);
border-radius: 8px;}
.presale-countdown h4 {
margin: 0 0 15px 0;
font-size: 16px;}
.countdown-timer {
display: flex;
justify-content: center;
gap: 15px;}
.countdown-unit {
text-align: center;
min-width: 70px;}
.countdown-unit .digit {
display: block;
font-size: 32px;
font-weight: bold;
background: rgba(255, 255, 255, 0.2);
padding: 10px;
border-radius: 5px;
margin-bottom: 5px;}
.countdown-unit .label {
font-size: 12px;
opacity: 0.8;
text-transform: uppercase;}
.countdown-ended {
text-align: center;
font-size: 18px;
font-weight: bold;
padding: 15px;
background: rgba(255, 255, 255, 0.2);
border-radius: 5px;}
