开发支持小批量生产的WordPress定制插件教程
概述
在当今数字化时代，许多中小型企业需要进行小批量生产的内容管理和展示。WordPress作为全球最流行的内容管理系统，通过定制插件可以轻松实现小批量生产管理功能。本教程将指导您开发一个完整的WordPress插件，用于管理小批量生产订单、产品和客户信息。
插件规划与结构设计
在开始编码之前，我们需要规划插件的基本功能：
- 产品管理：添加、编辑、删除小批量产品
- 订单管理：处理客户订单
- 客户管理：存储客户信息
- 生产状态跟踪：监控生产进度
- 数据报表：生成简单的生产报表
插件目录结构如下：
small-batch-production/
├── small-batch-production.php
├── includes/
│ ├── class-database.php
│ ├── class-products.php
│ ├── class-orders.php
│ └── class-admin.php
├── admin/
│ └── admin-pages.php
├── public/
│ └── public-display.php
└── assets/
├── css/
└── js/主插件文件开发
首先创建主插件文件，这是插件的入口点：
<?php
/**
* 插件名称: Small Batch Production Manager
* 插件URI: https://example.com/small-batch-production
* 描述: 用于管理小批量生产订单和产品的WordPress插件
* 版本: 1.0.0
* 作者: Your Name
* 作者URI: https://example.com
* 许可证: GPL v2或更高版本
* 文本域: small-batch-production
*/
// 防止直接访问
if (!defined('ABSPATH')) {
exit;
}
// 定义插件常量
define('SBP_VERSION', '1.0.0');
define('SBP_PLUGIN_DIR', plugin_dir_path(__FILE__));
define('SBP_PLUGIN_URL', plugin_dir_url(__FILE__));
// 插件激活时执行的操作
register_activation_hook(__FILE__, 'sbp_activate_plugin');
function sbp_activate_plugin() {
// 检查WordPress版本
if (version_compare(get_bloginfo('version'), '5.0', '<')) {
wp_die(__('此插件需要WordPress 5.0或更高版本', 'small-batch-production'));
}
// 创建数据库表
require_once SBP_PLUGIN_DIR . 'includes/class-database.php';
SBP_Database::create_tables();
// 设置默认选项
update_option('sbp_settings', array(
'items_per_page' => 20,
'currency' => 'USD',
'notify_admin' => true
));
}
// 插件停用时执行的操作
register_deactivation_hook(__FILE__, 'sbp_deactivate_plugin');
function sbp_deactivate_plugin() {
// 清理临时数据
delete_transient('sbp_daily_stats');
}
// 初始化插件
add_action('plugins_loaded', 'sbp_init_plugin');
function sbp_init_plugin() {
// 加载文本域用于国际化
load_plugin_textdomain('small-batch-production', false, dirname(plugin_basename(__FILE__)) . '/languages');
// 根据上下文加载不同的功能
if (is_admin()) {
require_once SBP_PLUGIN_DIR . 'includes/class-admin.php';
require_once SBP_PLUGIN_DIR . 'admin/admin-pages.php';
new SBP_Admin();
} else {
require_once SBP_PLUGIN_DIR . 'public/public-display.php';
}
// 加载公共功能
require_once SBP_PLUGIN_DIR . 'includes/class-database.php';
require_once SBP_PLUGIN_DIR . 'includes/class-products.php';
require_once SBP_PLUGIN_DIR . 'includes/class-orders.php';
}
// 添加插件设置链接
add_filter('plugin_action_links_' . plugin_basename(__FILE__), 'sbp_add_settings_link');
function sbp_add_settings_link($links) {
$settings_link = '<a href="admin.php?page=sbp-settings">' . __('设置', 'small-batch-production') . '</a>';
array_unshift($links, $settings_link);
return $links;
}
?>数据库管理类
接下来创建数据库管理类，用于处理所有数据库操作：
<?php
/**
* 数据库管理类
* 处理插件的所有数据库操作
*/
class SBP_Database {
/**
* 创建插件所需的数据库表
*/
public static function create_tables() {
global $wpdb;
$charset_collate = $wpdb->get_charset_collate();

// 订单表

// 客户表（简化版）

total_orders int DEFAULT 0,

require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
dbDelta($products_sql);
dbDelta($orders_sql);
dbDelta($customers_sql);
// 添加示例数据（仅用于演示）
self::add_sample_data();
}
/**

private static function add_sample_data() {

);
foreach ($sample_products as $product) {
$wpdb->insert($products_table, $product);
}
}
}
/**

?>产品管理类

?>管理界面实现
创建管理页面类，用于在WordPress后台显示管理界面：
<?php
/**
* 管理页面类
* 处理WordPress后台管理界面
*/
class SBP_Admin_Pages {
/**
* 初始化管理菜单
*/
public static function init_menu() {
// 主菜单
add_menu_page(
__('小批量生产管理', 'small-batch-production'),
__('生产管理', 'small-batch-production'),
'manage_options',
'sbp-dashboard',
array(__CLASS__, 'render_dashboard_page'),
'dashicons-products',
30
);
// 子菜单
add_submenu_page(
'sbp-dashboard',
__('产品管理', 'small-batch-production'),
__('产品', 'small-batch-production'),
'manage_options',
'sbp-products',
array(__CLASS__, 'render_products_page')
);
add_submenu_page(
'sbp-dashboard',接上文，继续生成管理界面实现代码：
<?php
/**
* 管理页面类
* 处理WordPress后台管理界面
*/
class SBP_Admin_Pages {
/**
* 初始化管理菜单
*/
public static function init_menu() {
// 主菜单
add_menu_page(

array(__CLASS__, 'render_orders_page')
);
add_submenu_page(
'sbp-dashboard',
__('客户管理', 'small-batch-production'),
__('客户', 'small-batch-production'),
'manage_options',
'sbp-customers',
array(__CLASS__, 'render_customers_page')
);
add_submenu_page(
'sbp-dashboard',
__('生产报表', 'small-batch-production'),
__('报表', 'small-batch-production'),

$in_production_orders = $wpdb->get_var("SELECT COUNT(*) FROM $orders_table WHERE status = 'in_production'");
// 获取最近订单
$recent_orders = $wpdb->get_results(

ORDER BY o.created_at DESC
