WordPress会议室预订与资源调度管理系统开发详细教程

引言：为什么需要会议室预订与资源调度系统

在现代办公环境中，会议室和各种共享资源（如投影仪、车辆、设备等）的高效管理是企业运营的重要环节。传统的人工预约方式不仅效率低下，还容易引发时间冲突和资源浪费。随着远程办公和混合工作模式的普及，一个数字化的资源调度系统变得尤为重要。

WordPress作为全球最流行的内容管理系统，不仅适用于博客和网站建设，通过代码二次开发，完全可以实现会议室预订与资源调度这样的专业功能。本教程将详细指导您如何从零开始，在WordPress平台上开发一个功能完善的会议室预订与资源调度管理系统。

第一部分：系统需求分析与规划

1.1 核心功能需求

在开始开发之前，我们需要明确系统应具备的核心功能：

1. 会议室管理：添加、编辑、删除会议室，设置容量、设备配置等信息
2. 资源管理：管理可预订资源（投影仪、白板、视频会议设备等）
3. 预订功能：用户可查看可用时间段并进行预订
4. 冲突检测：自动检测时间冲突，避免重复预订
5. 日历视图：直观展示会议室和资源的占用情况
6. 用户权限管理：不同用户角色拥有不同权限
7. 通知系统：预订确认、提醒、变更通知
8. 报表统计：使用频率统计、资源利用率分析

1.2 技术架构设计

我们将采用以下技术架构：

• 前端：HTML5、CSS3、JavaScript（jQuery）、FullCalendar.js
• 后端：PHP（WordPress核心）、MySQL数据库
• 通信：AJAX实现无刷新操作
• 安全性：WordPress非ces、数据验证、权限检查

1.3 数据库设计

我们需要创建以下自定义数据表：

1. wp_meeting_rooms：存储会议室信息
2. wp_resources：存储可预订资源信息
3. wp_bookings：存储预订记录
4. wp_booking_resources：预订与资源的关联表

第二部分：开发环境搭建与基础配置

2.1 开发环境准备

首先确保您具备以下环境：

• WordPress 5.0+ 安装
• PHP 7.4+ 版本
• MySQL 5.6+ 数据库
• 代码编辑器（VS Code、Sublime Text等）

2.2 创建自定义插件

我们将创建一个独立的插件来实现所有功能，确保与主题分离，便于维护和迁移。

在WordPress的wp-content/plugins/目录下创建新文件夹meeting-room-booking-system，并在其中创建主插件文件：

<?php
/**
 * Plugin Name: 会议室预订与资源调度管理系统
 * Plugin URI:  https://yourwebsite.com/
 * Description: 一个功能完整的会议室与资源预订管理系统
 * Version:     1.0.0
 * Author:      您的名称
 * License:     GPL v2 or later
 * Text Domain: mr-booking
 */

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

// 定义插件常量
define('MRB_PLUGIN_PATH', plugin_dir_path(__FILE__));
define('MRB_PLUGIN_URL', plugin_dir_url(__FILE__));
define('MRB_VERSION', '1.0.0');

// 初始化插件
require_once MRB_PLUGIN_PATH . 'includes/class-init.php';

2.3 创建数据库表

在插件初始化类中，添加创建数据库表的代码：

class MRB_Init {
    
    public function __construct() {
        // 激活插件时创建表
        register_activation_hook(__FILE__, array($this, 'create_tables'));
        
        // 加载其他组件
        $this->load_dependencies();
    }
    
    public function create_tables() {
        global $wpdb;
        
        $charset_collate = $wpdb->get_charset_collate();
        
        // 会议室表
        $rooms_table = $wpdb->prefix . 'meeting_rooms';
        $rooms_sql = "CREATE TABLE IF NOT EXISTS $rooms_table (
            id mediumint(9) NOT NULL AUTO_INCREMENT,
            name varchar(100) NOT NULL,
            description text,
            capacity smallint NOT NULL DEFAULT 10,
            location varchar(200),
            amenities text,
            status tinyint(1) DEFAULT 1,
            created_at datetime DEFAULT CURRENT_TIMESTAMP,
            PRIMARY KEY (id)
        ) $charset_collate;";
        
        // 资源表
        $resources_table = $wpdb->prefix . 'resources';
        $resources_sql = "CREATE TABLE IF NOT EXISTS $resources_table (
            id mediumint(9) NOT NULL AUTO_INCREMENT,
            name varchar(100) NOT NULL,
            type varchar(50) NOT NULL,
            description text,
            quantity smallint NOT NULL DEFAULT 1,
            status tinyint(1) DEFAULT 1,
            created_at datetime DEFAULT CURRENT_TIMESTAMP,
            PRIMARY KEY (id)
        ) $charset_collate;";
        
        // 预订表
        $bookings_table = $wpdb->prefix . 'bookings';
        $bookings_sql = "CREATE TABLE IF NOT EXISTS $bookings_table (
            id mediumint(9) NOT NULL AUTO_INCREMENT,
            room_id mediumint(9) NOT NULL,
            user_id bigint(20) NOT NULL,
            title varchar(200) NOT NULL,
            description text,
            start_time datetime NOT NULL,
            end_time datetime NOT NULL,
            attendees smallint DEFAULT 1,
            status varchar(20) DEFAULT 'confirmed',
            created_at datetime DEFAULT CURRENT_TIMESTAMP,
            PRIMARY KEY (id),
            KEY room_id (room_id),
            KEY user_id (user_id),
            KEY start_time (start_time),
            KEY end_time (end_time)
        ) $charset_collate;";
        
        // 预订资源关联表
        $booking_resources_table = $wpdb->prefix . 'booking_resources';
        $booking_resources_sql = "CREATE TABLE IF NOT EXISTS $booking_resources_table (
            id mediumint(9) NOT NULL AUTO_INCREMENT,
            booking_id mediumint(9) NOT NULL,
            resource_id mediumint(9) NOT NULL,
            quantity smallint NOT NULL DEFAULT 1,
            PRIMARY KEY (id),
            KEY booking_id (booking_id),
            KEY resource_id (resource_id)
        ) $charset_collate;";
        
        require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
        dbDelta($rooms_sql);
        dbDelta($resources_sql);
        dbDelta($bookings_sql);
        dbDelta($booking_resources_sql);
    }
    
    private function load_dependencies() {
        // 加载其他类文件
        require_once MRB_PLUGIN_PATH . 'includes/class-admin.php';
        require_once MRB_PLUGIN_PATH . 'includes/class-frontend.php';
        require_once MRB_PLUGIN_PATH . 'includes/class-ajax.php';
        require_once MRB_PLUGIN_PATH . 'includes/class-shortcodes.php';
    }
}

new MRB_Init();

第三部分：后台管理界面开发

3.1 创建管理菜单

在class-admin.php中，添加管理菜单功能：

class MRB_Admin {
    
    public function __construct() {
        add_action('admin_menu', array($this, 'add_admin_menus'));
        add_action('admin_enqueue_scripts', array($this, 'enqueue_admin_scripts'));
    }
    
    public function add_admin_menus() {
        // 主菜单
        add_menu_page(
            '会议室预订系统',
            '会议室预订',
            'manage_options',
            'mrb-dashboard',
            array($this, 'dashboard_page'),
            'dashicons-calendar-alt',
            30
        );
        
        // 子菜单
        add_submenu_page(
            'mrb-dashboard',
            '会议室管理',
            '会议室',
            'manage_options',
            'mrb-rooms',
            array($this, 'rooms_page')
        );
        
        add_submenu_page(
            'mrb-dashboard',
            '资源管理',
            '资源',
            'manage_options',
            'mrb-resources',
            array($this, 'resources_page')
        );
        
        add_submenu_page(
            'mrb-dashboard',
            '预订管理',
            '预订',
            'manage_options',
            'mrb-bookings',
            array($this, 'bookings_page')
        );
        
        add_submenu_page(
            'mrb-dashboard',
            '系统设置',
            '设置',
            'manage_options',
            'mrb-settings',
            array($this, 'settings_page')
        );
    }
    
    public function enqueue_admin_scripts($hook) {
        // 仅在我们的插件页面加载脚本
        if (strpos($hook, 'mrb-') !== false) {
            wp_enqueue_style('mrb-admin-style', MRB_PLUGIN_URL . 'assets/css/admin.css', array(), MRB_VERSION);
            wp_enqueue_script('mrb-admin-script', MRB_PLUGIN_URL . 'assets/js/admin.js', array('jquery'), MRB_VERSION, true);
            
            // 本地化脚本，传递数据到JS
            wp_localize_script('mrb-admin-script', 'mrb_admin', array(
                'ajax_url' => admin_url('admin-ajax.php'),
                'nonce' => wp_create_nonce('mrb_admin_nonce')
            ));
        }
    }
    
    public function dashboard_page() {
        include MRB_PLUGIN_PATH . 'templates/admin/dashboard.php';
    }
    
    public function rooms_page() {
        include MRB_PLUGIN_PATH . 'templates/admin/rooms.php';
    }
    
    public function resources_page() {
        include MRB_PLUGIN_PATH . 'templates/admin/resources.php';
    }
    
    public function bookings_page() {
        include MRB_PLUGIN_PATH . 'templates/admin/bookings.php';
    }
    
    public function settings_page() {
        include MRB_PLUGIN_PATH . 'templates/admin/settings.php';
    }
}

3.2 会议室管理界面

创建templates/admin/rooms.php文件：

<div class="wrap mrb-admin-wrap">
    <h1 class="wp-heading-inline">会议室管理</h1>
    <a href="#" class="page-title-action" id="mrb-add-room">添加新会议室</a>
    <hr class="wp-header-end">
    
    <!-- 添加/编辑会议室表单 (默认隐藏) -->
    <div id="mrb-room-form-container" style="display:none;">
        <h2 id="mrb-form-title">添加会议室</h2>
        <form id="mrb-room-form" method="post">
            <?php wp_nonce_field('mrb_save_room', 'mrb_room_nonce'); ?>
            <input type="hidden" id="room_id" name="room_id" value="0">
            
            <table class="form-table">
                <tr>
                    <th scope="row"><label for="room_name">会议室名称</label></th>
                    <td><input type="text" id="room_name" name="room_name" class="regular-text" required></td>
                </tr>
                <tr>
                    <th scope="row"><label for="room_capacity">容量</label></th>
                    <td><input type="number" id="room_capacity" name="room_capacity" min="1" max="500" value="10" required></td>
                </tr>
                <tr>
                    <th scope="row"><label for="room_location">位置</label></th>
                    <td><input type="text" id="room_location" name="room_location" class="regular-text"></td>
                </tr>
                <tr>
                    <th scope="row"><label for="room_description">描述</label></th>
                    <td><textarea id="room_description" name="room_description" rows="5" class="large-text"></textarea></td>
                </tr>
                <tr>
                    <th scope="row"><label for="room_amenities">设备配置</label></th>
                    <td>
                        <textarea id="room_amenities" name="room_amenities" rows="3" class="large-text" placeholder="例如：投影仪、白板、视频会议系统"></textarea>
                        <p class="description">每行一个设备，或使用逗号分隔</p>
                    </td>
                </tr>
                <tr>
                    <th scope="row"><label for="room_status">状态</label></th>
                    <td>
                        <select id="room_status" name="room_status">
                            <option value="1">可用</option>
                            <option value="0">不可用</option>
                        </select>
                    </td>
                </tr>
            </table>
            
            <p class="submit">
                <button type="submit" class="button button-primary">保存会议室</button>
                <button type="button" class="button" id="mrb-cancel-form">取消</button>
            </p>
        </form>
    </div>
    
    <!-- 会议室列表 -->
    <div id="mrb-rooms-list">
        <table class="wp-list-table widefat fixed striped">
            <thead>
                <tr>
                    <th scope="col" width="5%">ID</th>
                    <th scope="col" width="20%">名称</th>

                    <th scope="col" width="10%">操作</th>
                </tr>
            </thead>
            <tbody id="mrb-rooms-table-body">
                <!-- 通过AJAX加载数据 -->
                <tr>
                    <td colspan="7">加载中...</td>
                </tr>
            </tbody>
        </table>
    </div>
</div>

第四部分：前端预订界面开发

4.1 创建前端短代码

在class-shortcodes.php中，创建用于前端显示的短代码：

class MRB_Shortcodes {
    
    public function __construct() {
        add_shortcode('meeting_room_booking', array($this, 'booking_calendar_shortcode'));
        add_shortcode('meeting_room_list', array($this, 'room_list_shortcode'));
        add_action('wp_enqueue_scripts', array($this, 'enqueue_frontend_scripts'));
    }
    
    public function enqueue_frontend_scripts() {
        global $post;
        
        // 仅在包含我们短代码的页面加载脚本
        if (is_a($post, 'WP_Post') && has_shortcode($post->post_content, 'meeting_room_booking')) {
            
            // FullCalendar库
            wp_enqueue_style('fullcalendar-css', 'https://cdn.jsdelivr.net/npm/fullcalendar@5.10.1/main.min.css', array(), '5.10.1');
            wp_enqueue_script('fullcalendar-js', 'https://cdn.jsdelivr.net/npm/fullcalendar@5.10.1/main.min.js', array('jquery'), '5.10.1', true);
            
            // 本地化日历
            wp_enqueue_script('fullcalendar-locale', 'https://cdn.jsdelivr.net/npm/fullcalendar@5.10.1/locales/zh-cn.js', array('fullcalendar-js'), '5.10.1', true);
            
            // 插件前端样式和脚本
            wp_enqueue_style('mrb-frontend-style', MRB_PLUGIN_URL . 'assets/css/frontend.css', array(), MRB_VERSION);
            wp_enqueue_script('mrb-frontend-script', MRB_PLUGIN_URL . 'assets/js/frontend.js', array('jquery', 'fullcalendar-js'), MRB_VERSION, true);
            
            // 传递数据到前端JS
            wp_localize_script('mrb-frontend-script', 'mrb_frontend', array(
                'ajax_url' => admin_url('admin-ajax.php'),
                'nonce' => wp_create_nonce('mrb_frontend_nonce'),
                'current_user_id' => get_current_user_id(),
                'calendar_locale' => get_locale(),
                'time_format' => get_option('time_format', 'H:i'),
                'date_format' => get_option('date_format', 'Y-m-d')
            ));
        }
    }
    
    public function booking_calendar_shortcode($atts) {
        // 检查用户是否登录
        if (!is_user_logged_in()) {
            return '<div class="mrb-login-required">请先登录系统以预订会议室。</div>';
        }
        
        ob_start();
        include MRB_PLUGIN_PATH . 'templates/frontend/booking-calendar.php';
        return ob_get_clean();
    }
    
    public function room_list_shortcode($atts) {
        ob_start();
        include MRB_PLUGIN_PATH . 'templates/frontend/room-list.php';
        return ob_get_clean();
    }
}

4.2 预订日历界面

创建templates/frontend/booking-calendar.php：

<div class="mrb-booking-container">
    <div class="mrb-booking-header">
        <h2>会议室预订系统</h2>
        <div class="mrb-user-info">
            欢迎，<?php echo wp_get_current_user()->display_name; ?>！
        </div>
    </div>
    
    <div class="mrb-booking-main">
        <div class="mrb-sidebar">
            <div class="mrb-room-filter">
                <h3>筛选会议室</h3>
                <div class="mrb-filter-section">
                    <label for="mrb-filter-capacity">最小容量：</label>
                    <select id="mrb-filter-capacity">
                        <option value="0">不限</option>
                        <option value="5">5人以上</option>
                        <option value="10">10人以上</option>
                        <option value="20">20人以上</option>

<option value="30">30人以上</option>

                    <option value="50">50人以上</option>
                </select>
            </div>
            <div class="mrb-filter-section">
                <label for="mrb-filter-equipment">设备要求：</label>
                <div class="mrb-equipment-checkboxes">
                    <label><input type="checkbox" value="projector"> 投影仪</label>
                    <label><input type="checkbox" value="whiteboard"> 白板</label>
                    <label><input type="checkbox" value="videoconf"> 视频会议</label>
                    <label><input type="checkbox" value="phone"> 电话会议</label>
                </div>
            </div>
            <button id="mrb-apply-filter" class="button">应用筛选</button>
            <button id="mrb-reset-filter" class="button button-secondary">重置筛选</button>
        </div>

    add_action('wp_ajax_nopriv_mrb_get_bookings', array($this, 'get_bookings'));
    add_action('wp_ajax_mrb_create_booking', array($this, 'create_booking'));
    add_action('wp_ajax_mrb_cancel_booking', array($this, 'cancel_booking'));
    
    // 后台AJAX动作
    add_action('wp_ajax_mrb_admin_save_room', array($this, 'admin_save_room'));
    add_action('wp_ajax_mrb_admin_delete_room', array($this, 'admin_delete_room'));
