laravel-admin custom export form

Official export documentation

The export excel that comes with laravel-admin will export other data associated with this model. So refer to the official documentation to adjust the code

Article table: id, title, user_id

User table: id, username

//The article model is associated with the user
    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 ) {
                 // This logic is to extract the fields to be exported from the table data 
                $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');
    }
}
