实现小批量快速打样的WordPress集成插件教程

概述

在当今快速发展的电商环境中，小批量快速打样已成为产品开发的关键环节。本教程将指导您创建一个WordPress插件，帮助用户高效管理小批量打样流程。这个插件将包含产品提交、打样状态跟踪和团队协作功能，适合初创企业和小型设计团队使用。

插件架构设计

1. 插件基础结构

首先，我们创建插件的基本文件结构：

<?php
/**
 * 插件名称: 小批量快速打样管理系统
 * 版本: 1.0.0
 * 描述: 用于管理小批量产品打样流程的WordPress插件
 * 作者: 您的姓名
 * 文本域: rapid-prototyping
 */

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

// 定义插件常量
define('RP_PLUGIN_VERSION', '1.0.0');
define('RP_PLUGIN_PATH', plugin_dir_path(__FILE__));
define('RP_PLUGIN_URL', plugin_dir_url(__FILE__));

// 初始化插件
class RapidPrototypingPlugin {
    
    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('init', array($this, 'init'));
        
        // 管理菜单
        add_action('admin_menu', array($this, 'add_admin_menu'));
        
        // 加载脚本和样式
        add_action('admin_enqueue_scripts', array($this, 'enqueue_admin_scripts'));
        add_action('wp_enqueue_scripts', array($this, 'enqueue_frontend_scripts'));
    }
    
    public function activate() {
        $this->create_database_tables();
        $this->create_default_options();
    }
    
    public function deactivate() {
        // 清理临时数据
        $this->cleanup_temporary_data();
    }
    
    public function init() {
        // 加载文本域
        load_plugin_textdomain('rapid-prototyping', false, dirname(plugin_basename(__FILE__)) . '/languages');
        
        // 注册自定义文章类型
        $this->register_custom_post_types();
    }
    
    // 其他方法将在下面实现
}

// 启动插件
RapidPrototypingPlugin::get_instance();
?>

2. 数据库表设计

创建必要的数据库表来存储打样项目数据：

<?php
// 在RapidPrototypingPlugin类中添加以下方法

private function create_database_tables() {
    global $wpdb;
    
    $charset_collate = $wpdb->get_charset_collate();
    $table_name = $wpdb->prefix . 'rapid_prototyping_projects';
    
    // 项目表
    $sql = "CREATE TABLE IF NOT EXISTS $table_name (
        id mediumint(9) NOT NULL AUTO_INCREMENT,
        project_name varchar(255) NOT NULL,
        description text,
        designer_id bigint(20) NOT NULL,
        status varchar(50) DEFAULT 'draft',
        priority tinyint(1) DEFAULT 1,
        materials text,
        quantity int(11) DEFAULT 1,
        due_date datetime,
        created_at datetime DEFAULT CURRENT_TIMESTAMP,
        updated_at datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
        PRIMARY KEY (id),
        KEY designer_id (designer_id),
        KEY status (status)
    ) $charset_collate;";
    
    require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
    dbDelta($sql);
    
    // 打样版本表
    $versions_table = $wpdb->prefix . 'rapid_prototyping_versions';
    $sql = "CREATE TABLE IF NOT EXISTS $versions_table (
        id mediumint(9) NOT NULL AUTO_INCREMENT,
        project_id mediumint(9) NOT NULL,
        version_number varchar(20) NOT NULL,
        file_url varchar(500),
        notes text,
        feedback text,
        approved_by bigint(20),
        approved_at datetime,
        created_at datetime DEFAULT CURRENT_TIMESTAMP,
        PRIMARY KEY (id),
        KEY project_id (project_id),
        FOREIGN KEY (project_id) REFERENCES $table_name(id) ON DELETE CASCADE
    ) $charset_collate;";
    
    dbDelta($sql);
    
    // 团队成员表
    $team_table = $wpdb->prefix . 'rapid_prototyping_team';
    $sql = "CREATE TABLE IF NOT EXISTS $team_table (
        id mediumint(9) NOT NULL AUTO_INCREMENT,
        project_id mediumint(9) NOT NULL,
        user_id bigint(20) NOT NULL,
        role varchar(50) NOT NULL,
        added_at datetime DEFAULT CURRENT_TIMESTAMP,
        PRIMARY KEY (id),
        UNIQUE KEY project_user (project_id, user_id),
        FOREIGN KEY (project_id) REFERENCES $table_name(id) ON DELETE CASCADE
    ) $charset_collate;";
    
    dbDelta($sql);
}
?>

3. 管理界面实现

创建插件管理页面和功能：

<?php
// 在RapidPrototypingPlugin类中添加以下方法

public function add_admin_menu() {
    // 主菜单
    add_menu_page(
        __('快速打样管理', 'rapid-prototyping'),
        __('快速打样', 'rapid-prototyping'),
        'manage_options',
        'rapid-prototyping',
        array($this, 'render_dashboard_page'),
        'dashicons-hammer',
        30
    );
    
    // 子菜单
    add_submenu_page(
        'rapid-prototyping',
        __('所有项目', 'rapid-prototyping'),
        __('所有项目', 'rapid-prototyping'),
        'manage_options',
        'rp-projects',
        array($this, 'render_projects_page')
    );
    
    add_submenu_page(
        'rapid-prototyping',
        __('添加新项目', 'rapid-prototyping'),
        __('添加新项目', 'rapid-prototyping'),
        'manage_options',
        'rp-add-project',
        array($this, 'render_add_project_page')
    );
    
    add_submenu_page(
        'rapid-prototyping',
        __('设置', 'rapid-prototyping'),
        __('设置', 'rapid-prototyping'),
        'manage_options',
        'rp-settings',
        array($this, 'render_settings_page')
    );
}

public function render_dashboard_page() {
    ?>
    <div class="wrap rp-dashboard">
        <h1><?php _e('快速打样仪表板', 'rapid-prototyping'); ?></h1>
        
        <div class="rp-stats-container">
            <?php $this->display_statistics(); ?>
        </div>
        
        <div class="rp-recent-projects">
            <h2><?php _e('最近项目', 'rapid-prototyping'); ?></h2>
            <?php $this->display_recent_projects(); ?>
        </div>
    </div>
    <?php
}

private function display_statistics() {
    global $wpdb;
    $table_name = $wpdb->prefix . 'rapid_prototyping_projects';
    
    // 获取统计数据
    $total_projects = $wpdb->get_var("SELECT COUNT(*) FROM $table_name");
    $active_projects = $wpdb->get_var("SELECT COUNT(*) FROM $table_name WHERE status IN ('in_progress', 'review')");
    $completed_projects = $wpdb->get_var("SELECT COUNT(*) FROM $table_name WHERE status = 'completed'");
    
    ?>
    <div class="rp-stats-grid">
        <div class="rp-stat-card">
            <h3><?php echo esc_html($total_projects); ?></h3>
            <p><?php _e('总项目数', 'rapid-prototyping'); ?></p>
        </div>
        <div class="rp-stat-card">
            <h3><?php echo esc_html($active_projects); ?></h3>
            <p><?php _e('进行中项目', 'rapid-prototyping'); ?></p>
        </div>
        <div class="rp-stat-card">
            <h3><?php echo esc_html($completed_projects); ?></h3>
            <p><?php _e('已完成项目', 'rapid-prototyping'); ?></p>
        </div>
    </div>
    <?php
}
?>

4. 前端提交表单

创建用户提交打样请求的前端表单：

<?php
// 创建短码处理类
class RP_Shortcodes {
    
    public static function init() {
        add_shortcode('rp_submission_form', array(__CLASS__, 'render_submission_form'));
        add_shortcode('rp_project_status', array(__CLASS__, 'render_project_status'));
    }
    
    public static function render_submission_form($atts) {
        // 检查用户是否登录
        if (!is_user_logged_in()) {
            return '<p>' . __('请登录后提交打样请求。', 'rapid-prototyping') . '</p>';
        }
        
        ob_start();
        ?>
        <div class="rp-submission-form-container">
            <h2><?php _e('提交打样请求', 'rapid-prototyping'); ?></h2>
            
            <form id="rp-submission-form" method="post" enctype="multipart/form-data">
                <?php wp_nonce_field('rp_submit_project', 'rp_nonce'); ?>
                
                <div class="rp-form-group">
                    <label for="project_name"><?php _e('项目名称', 'rapid-prototyping'); ?> *</label>
                    <input type="text" id="project_name" name="project_name" required>
                </div>
                
                <div class="rp-form-group">
                    <label for="description"><?php _e('项目描述', 'rapid-prototyping'); ?></label>
                    <textarea id="description" name="description" rows="4"></textarea>
                </div>
                
                <div class="rp-form-row">
                    <div class="rp-form-group">
                        <label for="quantity"><?php _e('打样数量', 'rapid-prototyping'); ?></label>
                        <input type="number" id="quantity" name="quantity" min="1" max="100" value="1">
                    </div>
                    
                    <div class="rp-form-group">
                        <label for="priority"><?php _e('优先级', 'rapid-prototyping'); ?></label>
                        <select id="priority" name="priority">
                            <option value="1"><?php _e('低', 'rapid-prototyping'); ?></option>
                            <option value="2" selected><?php _e('中', 'rapid-prototyping'); ?></option>
                            <option value="3"><?php _e('高', 'rapid-prototyping'); ?></option>
                        </select>
                    </div>
                </div>
                
                <div class="rp-form-group">
                    <label for="materials"><?php _e('使用材料', 'rapid-prototyping'); ?></label>
                    <textarea id="materials" name="materials" rows="3" 
                              placeholder="<?php esc_attr_e('请详细描述所需材料...', 'rapid-prototyping'); ?>"></textarea>
                </div>
                
                <div class="rp-form-group">
                    <label for="due_date"><?php _e('期望完成日期', 'rapid-prototyping'); ?></label>
                    <input type="date" id="due_date" name="due_date">
                </div>
                
                <div class="rp-form-group">
                    <label for="design_files"><?php _e('设计文件', 'rapid-prototyping'); ?></label>
                    <input type="file" id="design_files" name="design_files[]" multiple accept=".jpg,.png,.pdf,.stl,.obj">
                    <p class="rp-help-text"><?php _e('支持JPG, PNG, PDF, STL, OBJ格式，最多5个文件', 'rapid-prototyping'); ?></p>
                </div>

                </div>
                
                <button type="submit" class="rp-submit-button">
                    <?php _e('提交打样请求', 'rapid-prototyping'); ?>
                </button>
                
                <div id="rp-form-message"></div>
            </form>
        </div>
        
        <script>
        jQuery(document).ready(function($) {
            $('#rp-submission-form').on('submit', function(e) {
                e.preventDefault();
                
                var formData = new FormData(this);
                formData.append('action', 'rp_submit_project');
                
                $.ajax({
                    url: '<?php echo admin_url("admin-ajax.php"); ?>',
                    type: 'POST',
                    data: formData,
                    processData: false,
                    contentType: false,
                    success: function(response) {
                        if (response.success) {
                            $('#rp-form-message').html(
                                '<div class="rp-success">' + response.data.message + '</div>'
                            );
                            $('#rp-submission-form')[0].reset();
                        } else {
                            $('#rp-form-message').html(
                                '<div class="rp-error">' + response.data.message + '</div>'
                            );
                        }
                    }
                });
            });
        });
        </script>
        <?php
        
        return ob_get_clean();
    }
}

// 在插件初始化时注册短码
add_action('init', array('RP_Shortcodes', 'init'));
?>

5. AJAX处理与数据验证

处理表单提交的AJAX请求：

<?php
// 在RapidPrototypingPlugin类中添加AJAX处理方法

private function init_ajax_handlers() {
    add_action('wp_ajax_rp_submit_project', array($this, 'handle_project_submission'));
    add_action('wp_ajax_nopriv_rp_submit_project', array($this, 'handle_no_privilege'));
    
    add_action('wp_ajax_rp_get_project_status', array($this, 'get_project_status'));
}

public function handle_project_submission() {
    // 验证nonce
    if (!wp_verify_nonce($_POST['rp_nonce'], 'rp_submit_project')) {
        wp_die(__('安全验证失败', 'rapid-prototyping'));
    }
    
    // 验证用户权限
    if (!is_user_logged_in()) {
        wp_send_json_error(array(
            'message' => __('请先登录', 'rapid-prototyping')
        ));
    }
    
    // 验证必填字段
    $required_fields = array('project_name');
    foreach ($required_fields as $field) {
        if (empty($_POST[$field])) {
            wp_send_json_error(array(
                'message' => sprintf(__('%s为必填字段', 'rapid-prototyping'), $field)
            ));
        }
    }
    
    global $wpdb;
    $table_name = $wpdb->prefix . 'rapid_prototyping_projects';
    
    // 准备数据
    $project_data = array(
        'project_name' => sanitize_text_field($_POST['project_name']),
        'description' => sanitize_textarea_field($_POST['description']),
        'designer_id' => get_current_user_id(),
        'status' => 'draft',
        'priority' => intval($_POST['priority']),
        'materials' => sanitize_textarea_field($_POST['materials']),
        'quantity' => intval($_POST['quantity']),
        'due_date' => !empty($_POST['due_date']) ? sanitize_text_field($_POST['due_date']) : null,
        'created_at' => current_time('mysql')
    );
    
    // 插入数据库
    $result = $wpdb->insert($table_name, $project_data);
    
    if ($result) {
        $project_id = $wpdb->insert_id;
        
        // 处理文件上传
        $this->handle_file_uploads($project_id);
        
        // 发送通知邮件
        $this->send_notification_email($project_id);
        
        wp_send_json_success(array(
            'message' => __('打样请求提交成功！', 'rapid-prototyping'),
            'project_id' => $project_id
        ));
    } else {
        wp_send_json_error(array(
            'message' => __('提交失败，请重试', 'rapid-prototyping')
        ));
    }
}

private function handle_file_uploads($project_id) {
    if (!empty($_FILES['design_files'])) {
        require_once(ABSPATH . 'wp-admin/includes/file.php');
        require_once(ABSPATH . 'wp-admin/includes/media.php');
        require_once(ABSPATH . 'wp-admin/includes/image.php');
        
        $files = $_FILES['design_files'];
        $upload_dir = wp_upload_dir();
        $rp_dir = $upload_dir['basedir'] . '/rapid-prototyping/' . $project_id;
        
        // 创建目录
        if (!file_exists($rp_dir)) {
            wp_mkdir_p($rp_dir);
        }
        
        // 处理多个文件
        foreach ($files['name'] as $key => $value) {
            if ($files['name'][$key]) {
                $file = array(
                    'name' => $files['name'][$key],
                    'type' => $files['type'][$key],
                    'tmp_name' => $files['tmp_name'][$key],
                    'error' => $files['error'][$key],
                    'size' => $files['size'][$key]
                );
                
                $upload_overrides = array('test_form' => false);
                $movefile = wp_handle_upload($file, $upload_overrides);
                
                if ($movefile && !isset($movefile['error'])) {
                    // 保存文件信息到数据库
                    $this->save_file_info($project_id, $movefile['url'], $file['name']);
                }
            }
        }
    }
}
?>

6. 样式与脚本优化

6. 样式与脚本优化

为插件添加专业的前端样式和交互功能：

<?php
