请问有没有插件开发手册，我想自己开发插件了

1.目前没有详细的开发fecmall应用市场插件的文档，但也有一些

http://www.fecmall.com/doc/fecshop-guide/addons/cn-2.0/guide-fecmall-addons-developer-add.html

fecmall后台油一个gii初始化生成器，可以生成初始化文件

2.应用市场有几个免费的扩展，您可以安装看一下文件结构

3.插件和本地二开的配置语法是一致的，原理就是通过配置覆盖的方式实现重写

贴一个配置你参考一下

<?php
/**
 * Fecmall Addons Config File
 */

// set namespace alisa
Yii::setAlias('@fecbdc', dirname(dirname(dirname(__DIR__))).'/addons/fecmall/fecbdc/');

        'install' => [

                        ],
                    ],
                ],
            ]
        ],
        // console，命令行脚本端
        'console' =>[],
    ],
    
    
];

配置重写这块太麻烦了，如果不是深入研究，非常熟练的话，这块得绕好久。有一定门槛。直接开发吧，又不能插件化放到应用市场。。
