Question

I have used library to generate barcode. Bar code is generated but problem is that how can i save that generated image?

Here i am giving my code i have used:

Answer 1

We can save barcode image into a directory or we can save it into database or both.

function set_barcode($code){
    //load library
    $this->load->library('zend');
    //load in folder Zend
    $this->zend->load('Zend/Barcode');

    //generate barcode
    $barcode = Zend_Barcode::factory('code128', 'image', array('text' => $code, 'barHeight'=>30, 'factor'=>2), array('imageType' => 'png'));

    //set dir path for barcode image store
    $path = './you/dir/path/'.$code.'.gif';
    imagegif($barcode->draw(), $path);

    /* if you want to permanently store your barcode image, and 
       save the path into your database, 
       just return this path. */
    // return $path

    //convert image into base64
    $code_img_base64 = base64_encode(file_get_contents($path));

    //if you want, remove the temporary barcode image
    unlink($path);

    return $code_img_base64;
}
