How to export database table to excel file in laravel

Posted 7 months ago by konrms

Hi guys.

I'm trying to export the table "formal", to a simple excel file. I have installed the packet necessary with "composer require maatwebsite/excel" command from cmd and also have edited my app.php file adding "Maatwebsite\Excel\ExcelServiceProvider::class," to providers and "'Excel' => Maatwebsite\Excel\Facades\Excel::class," to aliases.

My blade successfully shows "formal" as html. Now I have added a second button with export to excel option. Unfortunately, I'm getting an error "Call to undefined method Maatwebsite\Excel\Excel::create()" when pressing "Download excel button".

Could you help me please?

This is my blade with the "Download excel" button added.

This is the ExportExcelController:

<?php namespace App\Http\Controllers;

use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

    public function excel()
        $formal_data = DB::table('formal')->get()->toArray();
        $programma_array[] = array('lesson_category', 'lesson_code', 'lesson_title', 'lesson_dep', 'pms',
        'ergastitiaki_monada', 'tmima_ergastitiakis_monadas', 'username', 'epitheto', 'onoma', 'tutor_dep', 'vathmida', 
        'semester', 'ypoxreotiko', 'syndidaskalia', 'akroatirio');
        foreach($formal_data as $pass)
            $programma_array[] = array
            'lesson_category'  => $pass->lesson_category,
            'lesson_code'   => $pass->lesson_code,

            'pms'   => $pass->pms,
            'ergastitiaki_monada'   => $pass->ergastitiaki_monada,
            'tmima_ergastitiakis_monadas'   => $pass->tmima_ergastitiakis_monadas,
            'username'   => $pass->username,

            'onoma'   => $pass->onoma,
            'tutor_dep'   => $pass->tutor_dep,
            'vathmida'   => $pass->vathmida,
            'semester'   => $pass->semester,
            'ypoxreotiko'   => $pass->ypoxreotiko,

            'akroatirio'   => $pass->akroatirio,                
            Excel::create('Programma_Data', function($excel) use ($programma_array)
                $excel->sheet('Programma_Data', function($sheet) use ($programma_array)
                    $sheet->fromArray($programma_array, null, 'A1', false, false);
            }) -> download('xlsx');

And my web.php

Route::get('/excel', '[email protected]')->name('export_excel.excel');
