在现代生产管理中，实时了解生产进度对于提高效率和及时调整生产计划至关重要。本教程将指导您如何为WordPress创建一个定制插件，实现小批量生产进度的可视化展示。这个插件特别适合小型制造企业、手工作坊或任何需要跟踪多任务进度的场景。

我们的生产进度可视化插件将包含以下核心功能：

1. 生产任务管理（创建、编辑、删除任务）
2. 进度百分比跟踪
3. 可视化进度展示（进度条、图表）
4. 任务状态管理（未开始、进行中、已完成）
5. 数据导出功能

首先，在WordPress的wp-content/plugins目录下创建一个新文件夹，命名为production-progress-tracker。在该文件夹中创建主插件文件production-progress-tracker.php：

复制

<?php
/**
 * Plugin Name: 生产进度可视化追踪器
 * Plugin URI: https://yourwebsite.com/
 * Description: 一个小批量生产进度可视化追踪插件
 * Version: 1.0.0
 * Author: 您的名称
 * License: GPL v2 or later
 * Text Domain: production-progress
 */

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

// 定义插件常量
define('PPT_VERSION', '1.0.0');
define('PPT_PLUGIN_DIR', plugin_dir_path(__FILE__));
define('PPT_PLUGIN_URL', plugin_dir_url(__FILE__));

// 初始化插件
require_once PPT_PLUGIN_DIR . 'includes/class-production-progress.php';

function run_production_progress_tracker() {
    $plugin = new Production_Progress_Tracker();
    $plugin->run();
}
run_production_progress_tracker();

生产进度数据需要存储在数据库中。创建includes/class-database.php文件来管理数据库表：

复制

<?php
/**
 * 数据库处理类
 */
class PPT_Database {
    
    public function __construct() {
        // 构造函数
    }
    
    /**
     * 创建必要的数据库表
     */
    public function create_tables() {
        global $wpdb;
        
        $charset_collate = $wpdb->get_charset_collate();
        $table_name = $wpdb->prefix . 'production_tasks';
        
        // 生产任务表SQL
        $sql = "CREATE TABLE IF NOT EXISTS $table_name (
            id mediumint(9) NOT NULL AUTO_INCREMENT,
            task_name varchar(255) NOT NULL,
            description text,
            start_date date,
            due_date date,
            progress tinyint(3) DEFAULT 0,
            status varchar(50) DEFAULT 'pending',
            assigned_to varchar(255),
            created_at datetime DEFAULT CURRENT_TIMESTAMP,
            updated_at datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
            PRIMARY KEY (id)
        ) $charset_collate;";
        
        require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
        dbDelta($sql);
    }
    
    /**
     * 获取所有生产任务
     */
    public function get_all_tasks() {
        global $wpdb;
        $table_name = $wpdb->prefix . 'production_tasks';
        
        return $wpdb->get_results(
            "SELECT * FROM $table_name ORDER BY created_at DESC"
        );
    }
    
    /**
     * 添加新任务
     */
    public function add_task($data) {
        global $wpdb;
        $table_name = $wpdb->prefix . 'production_tasks';
        
        $wpdb->insert(
            $table_name,
            $data
        );
        
        return $wpdb->insert_id;
    }
    
    /**
     * 更新任务进度
     */
    public function update_progress($task_id, $progress) {
        global $wpdb;
        $table_name = $wpdb->prefix . 'production_tasks';
        
        return $wpdb->update(
            $table_name,
            array('progress' => $progress),
            array('id' => $task_id)
        );
    }
}

创建admin/class-admin.php文件来构建WordPress后台管理界面：

复制

<?php
/**
 * 管理界面类
 */
class PPT_Admin {
    
    private $database;
    
    public function __construct($database) {
        $this->database = $database;
        add_action('admin_menu', array($this, 'add_admin_menu'));
        add_action('admin_enqueue_scripts', array($this, 'enqueue_admin_scripts'));
    }
    
    /**
     * 添加管理菜单
     */
    public function add_admin_menu() {
        add_menu_page(
            '生产进度追踪',          // 页面标题
            '生产进度',             // 菜单标题
            'manage_options',       // 权限
            'production-progress',  // 菜单slug
            array($this, 'display_main_page'), // 回调函数
            'dashicons-chart-area', // 图标
            30                      // 位置
        );
        
        add_submenu_page(
            'production-progress',
            '添加新任务',
            '添加任务',
            'manage_options',
            'add-production-task',
            array($this, 'display_add_task_page')
        );
    }
    
    /**
     * 加载管理界面脚本和样式
     */
    public function enqueue_admin_scripts($hook) {
        if (strpos($hook, 'production-progress') === false) {
            return;
        }
        
        // 加载Chart.js用于可视化
        wp_enqueue_script(
            'chart-js',
            'https://cdn.jsdelivr.net/npm/chart.js',
            array(),
            '3.7.0',
            true
        );
        
        // 加载自定义CSS
        wp_enqueue_style(
            'ppt-admin-style',
            PPT_PLUGIN_URL . 'assets/css/admin-style.css',
            array(),
            PPT_VERSION
        );
        
        // 加载自定义JS
        wp_enqueue_script(
            'ppt-admin-script',
            PPT_PLUGIN_URL . 'assets/js/admin-script.js',

    }
