How to generate barcode in Codeigniter?

@samara 

To generate a barcode in CodeIgniter, you will need to use a barcode generation library. One option is to use the "Barcode Generator" library, which can be found at this link: https://github.com/bramp/php-barcode.

To use this library, you will need to download the files and place them in your CodeIgniter project. Then, you can use the following steps to generate a barcode:

1. Load the library in your controller:

1

$this->load->library('barcode');

1. Generate the barcode using the render() method of the library, passing in the barcode text and any options you want to set:

1

$barcode = $this->barcode->render('1234567890', 'code128', array('text' => true));

1. Display the barcode in your view by outputting the $barcode variable.

1

echo $barcode;

You can also specify the width and height of the barcode, and set other options such as the font size and margin size. You can refer to the library's documentation for more information on the available options.

To generate a barcode in CodeIgniter, you can follow these steps:

Step 1: Install the CodeIgniter Library

• Download and install the TCPDF library in the libraries folder of your CodeIgniter project. You can find the latest version of TCPDF on the official website: https://tcpdf.org/
• Extract the downloaded file and rename the TCPDF directory to "tcpdf". Move this directory to the libraries folder of your CodeIgniter project.

Step 2: Create a Barcode Helper

• Create a new file called "barcode_helper.php" in the application/helpers folder.
• Add the following code to the "barcode_helper.php" file:

 '',
        'align' => 'C',
        'stretch' => false,
        'fitwidth' => true,
        'cellfitalign' => '',
        'border' => false,
        'hpadding' => 'auto',
        'vpadding' => 'auto',
        'fgcolor' => array(0, 0, 0),
        'bgcolor' => false,
        'text' => true,
        'font' => 'helvetica',
        'fontsize' => 8,
        'stretchtext' => 4,
    );

    // Generate barcode
    $pdf->SetFont('helvetica', '', 8);
    $pdf->SetXY(15, 15);
    $pdf->write1DBarcode($code, 'C128', '', '', 45, 10, 0.4, $style, 'N');

    // Output PDF
    $pdf->Output('barcode.pdf', 'I');
}

Step 3: Load Helper and Generate Barcode

• In your controller or view, load the barcode helper using the following code:

1

$this->load->helper('barcode');

• Use the generate_barcode() function to generate the barcode. Pass the barcode value as the parameter.

1

generate_barcode('123456789');

This will generate a PDF file containing the barcode.

You can customize the barcode style in the $style array before generating the barcode. You can also modify the PDF file name and output type according to your requirements.
