fastadmin实现导出Excel和导入Excel数据

第一：导出数据为Excel

注意：直接url访问，不能使用ajax，因为ajax要求返回数据，和PHPExcel一会浏览器输出冲突！将数据作为参数

1、导出所有用户数据

代码：在index.html文件中的{:build_toolbar('refresh,del')}后面添加下面代码

 导出数据 

2、导出单个用户数据

代码

{field: 'id', title: __('按钮'), table: table, buttons:
                                [
                                    // {name: 'addname',
                                    //     text: '添加字段',
                                    //     title: '添加字段',
                                    //     icon: 'fa fa-list',
                                    //     classname: 'btn btn-xs btn-primary btn-dialog',//以弹窗方式
                                    //     url: 'zhuhai/msgcat/addname'
                                    // },
                                    {   name: '导出测评数据',
                                        text: '导出测评数据',
                                        title: '导出测评数据',
                                        icon: 'fa fa-flash',
                                        classname: 'btn btn-xs btn-success',//btn-ajax不能以以ajax方式请求
                                        url: 'appletls/user/out',
                                    },
                                ], operate:false, formatter: Table.api.formatter.buttons
                        },

php代码：

    }

第二：导入Excel【fastadmin自带导入】

注意：上传只支持xls、xlsx、csv三种格式的数据

1、在你的模块控制器下添加import方法
public function import(){
     return parent::import();
}

2、在index.html中的build_toolbar方法添加import，如下
{:build_toolbar(‘refresh,add,edit,del,import’)}

3、在模块对应的JS中添加import_url，如下
Table.api.init({
     extend: {
          index_url: ‘example/index’,
          add_url: ‘example/add’,
          edit_url: ‘example/edit’,
          del_url: ‘example/del’,
          import_url: ‘example/import’,
          multi_url: ‘example/multi’,
          dragsort_url: ‘’,
          table: ‘category’,
     }
});

第三：自定义导入Excel
