How to generate barcodes in laravel applications

Generating barcodes in an application has become a crucial ability.

If you have been having trouble doing this in your own applications, this shot will make it a breeze.

In just three steps you can get this up and running:

Step 1: Installation

First, we install milon\barcode, which is a composer package that supports barcode generation as follows:

composer require milon/barcode

Sample of a Barcode
Sample of a Barcode

Step 2: Controller Setup

public function generateBarcode(Request $request){
	$id = $request->get('id');
	$product = Product::find($id);
	return view('barcode')->with('product',$product);
}

The main purpose of the function in the above code is to return the barcode of the product received in the ＄request.

The function does so in three steps:

  1. Extracts id of the ＄request
  2. Finds the product corresponding to the ＄id
  3. Returns the barcode of the ＄product

Step 3: View Setup

The view for the function in Step 2 looks like this:

<div class="barcode">
    <p class="name">{{$product->name}}</p>
    <p class="price">Price: {{$product->sale_price}}</p>
    {!! DNS1D::getBarcodeHTML($product->pid, "C128",1.4,22) !!}
    <p class="pid">{{$product->pid}}</p>
</div>

In this view, we print the name, sale-price, barcode (using the DNS1D::getBarcodeHTML() method), and the pid of the product.

The DNS1D::getBarcodeHTML() receives four arguments:

  1. An identifier: In this case, we used the product id.

  2. Barcode type: In this case, we used the C128.

  3. Barcode height (dimension)

  4. Barcode width (dimension)
