Introduction
In today’s digital age, data is a valuable asset for businesses. Being able to import and export data to and from different formats is crucial for efficient data management. Laravel, a popular PHP framework, provides a powerful package called Maatwebsite that allows developers to easily import and export data to Excel and CSV files.
In this step-by-step guide, we will walk you through the process of installing and using Maatwebsite in Laravel 5 to import and export data to Excel and CSV files.
Prerequisites
Before we begin, make sure you have the following prerequisites:
1. Laravel 5 installed on your local machine.
2. Basic knowledge of Laravel and PHP.
3. Composer installed on your local machine.
Installation
To get started, open your terminal and navigate to your Laravel project directory. Then, run the following command to install Maatwebsite:
composer require maatwebsite/excel
This command will download and install the Maatwebsite package along with its dependencies.
Once the installation is complete, open the `config/app.php` file in your Laravel project and add the following line to the `providers` array:
MaatwebsiteExcelExcelServiceProvider::class,
Next, add the following line to the `aliases` array:
‘Excel’ => MaatwebsiteExcelFacadesExcel::class,
Save the changes and close the file.
Importing Data
Now that we have Maatwebsite installed and configured, let’s see how we can import data from Excel and CSV files into our Laravel application.
First, create a new controller by running the following command in your terminal:
php artisan make:controller ImportController
This command will generate a new controller file named `ImportController.php` in the `app/Http/Controllers` directory.
Open the `ImportController.php` file and add the following code:
«`php
file(‘file’);
Excel::import($file, function($reader) {
// Process the imported data
});
return redirect()->back()->with(‘success’, ‘Data imported successfully!’);
}
}
«`
In this code, we define a `import` method that takes a `Request` object as a parameter. Inside the method, we retrieve the uploaded file using the `file` method of the `Request` object. Then, we use the `Excel::import` method to import the data from the file. You can process the imported data inside the callback function.
Next, open the `routes/web.php` file and add the following route:
Route::post(‘/import’, ‘ImportController@import’)->name(‘import’);
Save the changes and close the file.
Now, let’s create a view file for the import form. Create a new file named `import.blade.php` in the `resources/views` directory and add the following code:
«`html
«`
In this code, we define a form that uploads a file and submits it to the `import` route. Make sure to include the `@csrf` directive to protect against cross-site request forgery attacks.
Finally, open the `app/Http/Kernel.php` file and add the following line to the `$routeMiddleware` array:
‘web’ => AppHttpMiddlewareEncryptCookies::class,
Save the changes and close the file.
Now, if you navigate to the `/import` route in your browser, you should see the import form. Select a file and click the «Import» button to import the data.
Exporting Data
In addition to importing data, Maatwebsite also allows us to export data from our Laravel application to Excel and CSV files. Let’s see how we can do that.
First, create a new controller by running the following command in your terminal:
php artisan make:controller ExportController
This command will generate a new controller file named `ExportController.php` in the `app/Http/Controllers` directory.
Open the `ExportController.php` file and add the following code:
«`php
setTitle(‘Users’);
$excel->sheet(‘Sheet 1’, function($sheet) use ($data) {
$sheet->fromArray($data, null, ‘A1’, false, false);
});
}, ‘users.xlsx’);
}
}
«`
In this code, we define an `export` method that generates an array of data to be exported. We then use the `Excel::download` method to generate the Excel file. Inside the callback function, we set the title of the Excel file and add the data to the first sheet.
Next, open the `routes/web.php` file and add the following route:
Route::get(‘/export’, ‘ExportController@export’)->name(‘export’);
Save the changes and close the file.
Now, if you navigate to the `/export` route in your browser, the Laravel application will generate and download an Excel file named `users.xlsx` containing the data specified in the `export` method.
