  11. </div>
  12. </nav>
  13. <div class="col-md-3"></div>
  14. <div class="col-md-6 well">

  25. <br />
  26. <?php include 'generate.php'?>
  27. </div>
  28. </form>
  29. </div>
  30. </div>
  31. </body>
  32. </html>

Creating The Main Function

This code contains the main function of the application. This script will render a barcode image when the user enter some data in the input. To create this just write these block of code inside the text editor. Save this as generate.php

  1. <?php
  2. if(ISSET($_POST['generate'])){
  3. $code=$_POST['barcode'];
  4. echo "<center><img alt='testing' src='barcode.php?codetype=code39&size=50&text=".$code."&print=true'/></center>";
  5. }
  6. ?>
