How to Use Barcode Scanner With Datatables Laravel?

6 minutes read

To use a barcode scanner with DataTables in Laravel, you can follow these steps:

  1. Implement a barcode scanner into your front-end application that can scan and read barcodes.
  2. Create a route in your Laravel application that will receive the scanned barcode data.
  3. Use an AJAX request in your DataTables implementation to send the scanned barcode data to the route created in step 2.
  4. In the Laravel controller method that handles the scanned barcode data, query your database to retrieve the relevant information based on the scanned barcode.
  5. Return the data retrieved from the database back to the front-end application.
  6. Update the DataTables instance with the data returned from the server to display the information related to the scanned barcode.


By following these steps, you can effectively integrate a barcode scanner with DataTables in your Laravel application to enhance user experience and streamline data input processes.


What are some practical applications for using a barcode scanner with datatables in Laravel?

  1. Inventory management: Barcode scanners can be used to quickly and accurately track inventory items in a warehouse or retail store. By integrating a barcode scanner with datatables in Laravel, users can easily scan barcodes to update inventory levels in real-time.

How to scan barcodes and display data in datatables using Laravel?

To scan barcodes and display data in datatables using Laravel, you can follow these steps:

  1. Install Laravel and set up a basic project structure.
  2. Install the Laravel Collective HTML package for easier form handling and rendering. You can install it using Composer by running the following command:
1
composer require laravelcollective/html


  1. Create a migration and model for the table where you will store barcode data. For example, you can create a products table with columns like name, barcode, price, etc.
  2. Create a form in your Blade view where users can input barcodes. You can use the HTML package to create a form like this:
1

3
4
{!! Form::open(['route' => 'scanned-barcode.store']) !!}
  {!! Form::text('barcode', null, ['class' => 'form-control', 'placeholder' => 'Scan barcode...']) !!}
  {!! Form::submit('Submit', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}


  1. Create a controller with the necessary methods for scanning and displaying barcode data. You can create a controller with the following command:
1
php artisan make:controller BarcodeController


  1. In the controller, create methods for storing scanned barcodes, listing all barcodes in the datatable, and returning the data as a JSON response.
  2. Install the DataTables JQuery plugin in your project for displaying data in a table format. You can include the DataTables CDN in your Blade view like this:
1
2
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.25/css/jquery.dataTables.min.css">
<script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.25/js/jquery.dataTables.min.js"></script>


  1. Use AJAX to fetch data from your Laravel backend and load it into the DataTable. You can make an AJAX call in your Blade view like this:
 1
 2
 3
 4
 5
 6
 7
 8
 9

11
$('#barcode-table').DataTable({
    processing: true,
    serverSide: true,
    ajax: "{{ route('scanned-barcode.index') }}",
    columns: [
        {data: 'id', name: 'id'},
        {data: 'barcode', name: 'barcode'},
        {data: 'name', name: 'name'},
        {data: 'price', name: 'price'},
    ]
});


  1. Finally, in your controller, return the scanned barcode data as a JSON response when requested. You can do this using the DataTable library in Laravel by modifying the method that fetches and returns the scanned barcode data.


By following these steps, you can scan barcodes and display data in datatables using Laravel.


How to create custom functionality for barcode scanning with datatables in Laravel?

To create custom functionality for barcode scanning with datatables in Laravel, you can follow these steps:

  1. Install the required packages: Install the Barcode Scanner library for Laravel: composer require milon/barcode Install DataTables library for Laravel: composer require yajra/laravel-datatables-oracle
  2. Create a new route in your routes/web.php file: Route::get('/barcode-scanner', 'BarcodeScannerController@index');
  3. Create a new controller for barcode scanning: php artisan make:controller BarcodeScannerController
  4. Update the BarcodeScannerController with the following code: get('barcode'); $product = Product::where('barcode', $barcode)->first(); return response()->json($product); } }
  5. Create a new view for barcode scanning: Create a new folder resources/views/barcode-scanner Create a new file index.blade.php in the barcode-scanner folder with the following code: Search
    NamePriceDescription
  6. Update the web.php file to include the route for searching by barcode: Route::post('/search-by-barcode', 'BarcodeScannerController@searchByBarcode');
  7. Make sure to include the necessary CSS and JS files in your layout file to enable DataTables functionality.


Now you have a custom functionality for barcode scanning with datatables in Laravel. When a user enters a barcode and clicks the search button, it will make an AJAX request to search for the product by barcode and display the details in a datatable format.


What is the role of datatables in conjunction with a barcode scanner in Laravel?

In Laravel, datatables can be used to display table data in a more interactive and user-friendly way. When used in conjunction with a barcode scanner, datatables can help improve the efficiency of data entry tasks by allowing users to quickly scan barcodes to populate fields in the table.


For example, when a barcode is scanned using a barcode scanner, the scanned data can be automatically populated into the corresponding fields in the datatables. This can help reduce the need for manual data entry and minimize errors.


Overall, using datatables in conjunction with a barcode scanner in Laravel can streamline data entry processes and improve the accuracy and efficiency of managing data.


How to validate scanned barcodes and update datatables in Laravel?

To validate scanned barcodes and update datatables in Laravel, you can follow these steps:

  1. Create a form in your Laravel application where users can input scanned barcodes.
  2. Use JavaScript to listen for when a barcode is scanned and send an AJAX request to your Laravel backend with the scanned barcode.
  3. In your Laravel controller, create a method that validates the scanned barcode. You can use the Laravel validation rules to check if the barcode is in the correct format or if it exists in your database.
  4. If the scanned barcode is valid, update the appropriate datatable in your database with the new information.
  5. Return a response to the frontend indicating whether the barcode was successfully validated and the datatable updated.
  6. Update the frontend UI to display the result of the validation and datatable update.


By following these steps, you can validate scanned barcodes and update datatables in your Laravel application.
