laravel-admin 自定義導出表單

官方導出文檔

laravel-admin自帶的導出excel會導出與此模型關聯的其餘數據。因此參考官方文檔調整代碼

文章表:id,title,user_id

用戶表:id,username

//文章模型關聯用戶
    public function user(){ return $this->belongsTo(User::class, 'user_id', 'id'); } 

//ExcelExporter.php
<?php namespace App\Admin\Extensions; use Encore\Admin\Grid; use Encore\Admin\Grid\Exporters\AbstractExporter; use Maatwebsite\Excel\Facades\Excel; class ExcelExpoter extends AbstractExporter { protected $head = []; protected $body = []; public function setAttr($head, $body){ $this->head = $head; $this->body = $body; } public function export() { Excel::create('Filename', function($excel) { $excel->sheet('Sheetname', function($sheet) { // 這段邏輯是從表格數據中取出須要導出的字段
                $head = $this->head; $body = $this->body; $bodyRows = collect($this->getData())->map(function ($item)use($body) { foreach ($body as $keyName){ $arr[] = array_get($item, $keyName); } return $arr; }); $rows = collect([$head])->merge($bodyRows); $sheet->rows($rows); }); })->export('xls'); } }

使用方法：

$excel = new ExcelExpoter(); $excel->setAttr(['id', '標題', '做者'], ['id', 'title', 'user.username']); $grid->exporter($excel);
