WordPress文创IP柔性周边开发项目管理插件教程

一、项目概述与需求分析

文创IP柔性周边开发是一个复杂的过程，涉及设计、生产、库存、销售等多个环节。在WordPress中实现项目管理功能，可以帮助团队高效协作，跟踪项目进度，管理产品生命周期。

核心需求包括：

1. 项目创建与基本信息管理
2. 任务分配与进度跟踪
3. 设计稿版本管理
4. 生产流程监控
5. 库存与销售数据关联

二、插件基础结构搭建

首先，我们需要创建插件的基本文件结构：

<?php
/**
 * Plugin Name: 文创IP项目管理
 * Plugin URI: https://yourwebsite.com/
 * Description: 文创IP柔性周边开发项目管理插件
 * Version: 1.0.0
 * Author: 你的名字
 * License: GPL v2 or later
 */

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

// 定义插件常量
define('CULTURAL_PROJECT_VERSION', '1.0.0');
define('CULTURAL_PROJECT_PLUGIN_DIR', plugin_dir_path(__FILE__));
define('CULTURAL_PROJECT_PLUGIN_URL', plugin_dir_url(__FILE__));

// 初始化插件
add_action('init', 'cultural_project_init');

function cultural_project_init() {
    // 加载文本域
    load_plugin_textdomain('cultural-project', false, dirname(plugin_basename(__FILE__)) . '/languages');
    
    // 注册自定义文章类型
    register_project_post_type();
    
    // 注册自定义分类法
    register_project_taxonomies();
}

// 激活插件时创建数据库表
register_activation_hook(__FILE__, 'cultural_project_activate');

function cultural_project_activate() {
    // 创建必要的数据库表
    create_project_tables();
    
    // 设置默认选项
    update_option('cultural_project_version', CULTURAL_PROJECT_VERSION);
}
?>

三、自定义文章类型与分类法

创建项目管理所需的文章类型和分类系统：

<?php
// 注册项目自定义文章类型
function register_project_post_type() {
    $labels = array(
        'name'               => __('文创项目', 'cultural-project'),
        'singular_name'      => __('文创项目', 'cultural-project'),
        'menu_name'          => __('文创项目管理', 'cultural-project'),
        'add_new'            => __('添加新项目', 'cultural-project'),
        'add_new_item'       => __('添加新文创项目', 'cultural-project'),
        'edit_item'          => __('编辑项目', 'cultural-project'),
        'new_item'           => __('新项目', 'cultural-project'),
        'view_item'          => __('查看项目', 'cultural-project'),
        'search_items'       => __('搜索项目', 'cultural-project'),
        'not_found'          => __('未找到项目', 'cultural-project'),
        'not_found_in_trash' => __('回收站中无项目', 'cultural-project')
    );
    
    $args = array(
        'labels'             => $labels,
        'public'             => true,
        'publicly_queryable' => true,
        'show_ui'            => true,
        'show_in_menu'       => true,
        'query_var'          => true,
        'rewrite'            => array('slug' => 'cultural-project'),
        'capability_type'    => 'post',
        'has_archive'        => true,
        'hierarchical'       => false,
        'menu_position'      => 25,
        'menu_icon'          => 'dashicons-portfolio',
        'supports'           => array('title', 'editor', 'thumbnail', 'custom-fields'),
        'show_in_rest'       => true // 启用Gutenberg编辑器支持
    );
    
    register_post_type('cultural_project', $args);
}

// 注册项目分类法
function register_project_taxonomies() {
    // 项目状态分类
    $status_labels = array(
        'name'              => __('项目状态', 'cultural-project'),
        'singular_name'     => __('项目状态', 'cultural-project'),
        'search_items'      => __('搜索状态', 'cultural-project'),
        'all_items'         => __('所有状态', 'cultural-project'),
        'edit_item'         => __('编辑状态', 'cultural-project'),
        'update_item'       => __('更新状态', 'cultural-project'),
        'add_new_item'      => __('添加新状态', 'cultural-project'),
        'new_item_name'     => __('新状态名称', 'cultural-project'),
        'menu_name'         => __('项目状态', 'cultural-project')
    );
    
    $status_args = array(
        'hierarchical'      => true,
        'labels'            => $status_labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'query_var'         => true,
        'rewrite'           => array('slug' => 'project-status'),
        'show_in_rest'      => true
    );
    
    register_taxonomy('project_status', array('cultural_project'), $status_args);
    
    // IP分类
    $ip_labels = array(
        'name'              => __('IP分类', 'cultural-project'),
        'singular_name'     => __('IP分类', 'cultural-project'),
        'search_items'      => __('搜索IP', 'cultural-project'),
        'all_items'         => __('所有IP', 'cultural-project'),
        'edit_item'         => __('编辑IP', 'cultural-project'),
        'update_item'       => __('更新IP', 'cultural-project'),
        'add_new_item'      => __('添加新IP', 'cultural-project'),
        'new_item_name'     => __('新IP名称', 'cultural-project'),
        'menu_name'         => __('IP分类', 'cultural-project')
    );
    
    $ip_args = array(
        'hierarchical'      => true,
        'labels'            => $ip_labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'query_var'         => true,
        'rewrite'           => array('slug' => 'ip-category'),
        'show_in_rest'      => true
    );
    
    register_taxonomy('ip_category', array('cultural_project'), $ip_args);
}
?>

四、项目元数据管理

为项目添加自定义字段，存储项目详细信息：

<?php
// 添加项目元数据框
add_action('add_meta_boxes', 'cultural_project_add_meta_boxes');

function cultural_project_add_meta_boxes() {
    add_meta_box(
        'cultural_project_details',
        __('项目详情', 'cultural-project'),
        'cultural_project_details_callback',
        'cultural_project',
        'normal',
        'high'
    );
    
    add_meta_box(
        'cultural_project_tasks',
        __('项目任务', 'cultural-project'),
        'cultural_project_tasks_callback',
        'cultural_project',
        'normal',
        'high'
    );
}

// 项目详情元数据框回调函数
function cultural_project_details_callback($post) {
    // 添加安全验证
    wp_nonce_field('cultural_project_save_data', 'cultural_project_meta_nonce');
    
    // 获取现有值
    $budget = get_post_meta($post->ID, '_project_budget', true);
    $start_date = get_post_meta($post->ID, '_project_start_date', true);
    $end_date = get_post_meta($post->ID, '_project_end_date', true);
    $product_manager = get_post_meta($post->ID, '_product_manager', true);
    $designer = get_post_meta($post->ID, '_designer', true);
    
    // 输出表单字段
    ?>
    <table class="form-table">
        <tr>
            <th><label for="project_budget"><?php _e('项目预算 (元)', 'cultural-project'); ?></label></th>
            <td>
                <input type="number" id="project_budget" name="project_budget" 
                       value="<?php echo esc_attr($budget); ?>" class="regular-text" step="0.01" min="0">
            </td>
        </tr>
        <tr>
            <th><label for="project_start_date"><?php _e('开始日期', 'cultural-project'); ?></label></th>
            <td>
                <input type="date" id="project_start_date" name="project_start_date" 
                       value="<?php echo esc_attr($start_date); ?>" class="regular-text">
            </td>
        </tr>
        <tr>
            <th><label for="project_end_date"><?php _e('预计完成日期', 'cultural-project'); ?></label></th>
            <td>
                <input type="date" id="project_end_date" name="project_end_date" 
                       value="<?php echo esc_attr($end_date); ?>" class="regular-text">
            </td>
        </tr>
        <tr>
            <th><label for="product_manager"><?php _e('产品经理', 'cultural-project'); ?></label></th>
            <td>
                <input type="text" id="product_manager" name="product_manager" 
                       value="<?php echo esc_attr($product_manager); ?>" class="regular-text">
            </td>
        </tr>
        <tr>
            <th><label for="designer"><?php _e('设计师', 'cultural-project'); ?></label></th>
            <td>
                <input type="text" id="designer" name="designer" 
                       value="<?php echo esc_attr($designer); ?>" class="regular-text">
            </td>
        </tr>
    </table>
    <?php
}

// 保存元数据
add_action('save_post', 'cultural_project_save_meta_data');

function cultural_project_save_meta_data($post_id) {
    // 检查非ce
    if (!isset($_POST['cultural_project_meta_nonce'])) {
        return;
    }
    
    // 验证nonce
    if (!wp_verify_nonce($_POST['cultural_project_meta_nonce'], 'cultural_project_save_data')) {
        return;
    }
    
    // 检查自动保存
    if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
        return;
    }
    
    // 检查用户权限
    if (!current_user_can('edit_post', $post_id)) {
        return;
    }
    
    // 保存字段数据
    $fields = array(
        'project_budget',
        'project_start_date',
        'project_end_date',
        'product_manager',
        'designer'
    );
    
    foreach ($fields as $field) {
        if (isset($_POST[$field])) {
            update_post_meta($post_id, '_' . $field, sanitize_text_field($_POST[$field]));
        }
    }
}
?>

五、任务管理系统

实现项目任务管理功能：

<?php
// 任务管理回调函数
function cultural_project_tasks_callback($post) {
    // 获取现有任务
    $tasks = get_post_meta($post->ID, '_project_tasks', true);
    $tasks = $tasks ? json_decode($tasks, true) : array();
    
    ?>
    <div id="project-tasks-container">
        <table class="widefat fixed" id="tasks-table">
            <thead>
                <tr>
                    <th width="5%"><?php _e('ID', 'cultural-project'); ?></th>
                    <th width="30%"><?php _e('任务名称', 'cultural-project'); ?></th>
                    <th width="15%"><?php _e('负责人', 'cultural-project'); ?></th>
                    <th width="15%"><?php _e('截止日期', 'cultural-project'); ?></th>
                    <th width="10%"><?php _e('状态', 'cultural-project'); ?></th>
                    <th width="10%"><?php _e('优先级', 'cultural-project'); ?></th>
                    <th width="15%"><?php _e('操作', 'cultural-project'); ?></th>
                </tr>
            </thead>
            <tbody id="tasks-list">
                <?php if (!empty($tasks)): ?>
                    <?php foreach ($tasks as $index => $task): ?>
                    <tr data-index="<?php echo $index; ?>">
                        <td><?php echo $index + 1; ?></td>
                        <td><input type="text" name="tasks[<?php echo $index; ?>][name]" 
                                   value="<?php echo esc_attr($task['name']); ?>" class="regular-text"></td>
                        <td><input type="text" name="tasks[<?php echo $index; ?>][assignee]" 
                                   value="<?php echo esc_attr($task['assignee']); ?>" class="regular-text"></td>
                        <td><input type="date" name="tasks[<?php echo $index; ?>][due_date]" 
                                   value="<?php echo esc_attr($task['due_date']); ?>" class="regular-text"></td>
                        <td>
                            <select name="tasks[<?php echo $index; ?>][status]" class="regular-text">
                                <option value="pending" <?php selected($task['status'], 'pending'); ?>><?php _e('待开始', 'cultural-project'); ?></option>
                                <option value="in_progress" <?php selected($task['status'], 'in_progress'); ?>><?php _e('进行中', 'cultural-project'); ?></option>

                            </select>
                        </td>
                        <td>
                            <select name="tasks[<?php echo $index; ?>][priority]" class="regular-text">
                                <option value="low" <?php selected($task['priority'], 'low'); ?>><?php _e('低', 'cultural-project'); ?></option>

                            </select>
                        </td>
                        <td>

    </script>
    <?php

    }

} else {
    delete_post_meta($post_id, '_project_tasks');
}

}
?>

## 六、设计稿版本管理系统

文创IP开发中设计稿版本管理至关重要，以下是实现代码：

<?php
// 添加设计稿管理元数据框
add_action('add_meta_boxes', 'cultural_project_design_meta_box');

function cultural_project_design_meta_box() {

add_meta_box(
    'cultural_project_designs',
    __('设计稿管理', 'cultural-project'),
    'cultural_project_designs_callback',
    'cultural_project',
    'side',
    'default'
);

}

// 设计稿管理回调函数
function cultural_project_designs_callback($post) {

// 获取现有设计稿
$designs = get_post_meta($post->ID, '_project_designs', true);
$designs = $designs ? json_decode($designs, true) : array();

wp_nonce_field('cultural_project_save_designs', 'cultural_project_design_nonce');
?>
<div id="design-version-manager">
    <div id="design-list">
        <?php if (!empty($designs)): ?>
            <?php foreach ($designs as $index => $design): ?>
            <div class="design-item" data-index="<?php echo $index; ?>">
                <h4><?php echo esc_html($design['version']); ?> - <?php echo esc_html($design['title']); ?></h4>
                <p><strong><?php _e('设计师:', 'cultural-project'); ?></strong> <?php echo esc_html($design['designer']); ?></p>

                <?php endif; ?>

            </div>
            <?php endforeach; ?>
        <?php endif; ?>
    </div>
    
    <hr>
