列表对象 maatwebsite/Laravel-Excel 中的 Laravel excel 导出列表

Question

您好，我想将包含所有孩子的人员列表导出到 Excel。我正在使用 maatwebsite/Laravel-Excel 插件，它很容易导出用户集合，但我需要在该行中包含每个孩子的用户。它类似于 [{Name, Age, Gender, Job, Children[{name, age, gender, etc...}], Birthday, etc...}]。以及如何更改 Excel 上显示的数据列的顺序，就像我想切换年龄和性别的数据一样。谢谢！

您可以使用WithMapping https://docs.laravel-excel.com/3.1/exports/mapping.html

<?php
    public function map($user): array
    {
        //create initial array with user data in order that you want columns to be
        $data = [
           $user->name
           ...
        ];
        // the same way you should crate headers (if you have). But instead of values you should create column name
        foreach($user->children as $child){
            array_push($data, $child->name, $child->birthday, $child->...., ..., ...); //and so on
        }

        // returned data should be 1 level array as each item is a row in the table
        return $data;
    }
