Kesempatan kali ini kita akan mencoba membuat barcode di php. Persiapan pertama yaitu siapkan folder projek bernama barcode.
Setelah membuat folder barcode, silahkan buat file barcode.php dan index.php di dalamnya.
Selanjutnya silahkan masukan script di bawah ini ke dalam index.php
index.php
<html>
<head>
<title>Generate Barcode di PHP</title>
</head>
<body>
<h4>Generate Barcode di PHP</h4>
<hr>
<form action="<?= $_SERVER['PHP_SELF'] ?>" method="POST">
<input type="text" name="barcode">
<input type="submit" name="simpan" value="Simpan">
</form>
<br>
<div>
<?php
if(isset($_POST['simpan'])){
echo "<left><img alt='testing' src='barcode.php?codetype=code39&size=15&text=".$_POST['barcode']."&print=true'/></left>";
}
?>
</div>
</body>
</html>
Selanjutnya masukan juga script di bawah ini ke dalam barcode.php
barcode.php
<?php

?>
Lalu coba jalankan, maka akan ada tampilan untuk input. silahkan isi dan klik tombol simpan maka akan ada barcode muncul
