A text must be provide to Barcode before drawing in codeigniter

I use zend libraries to generate barcode in codeigniter.

This is my controller :

$this->load->library('zend');
$this->zend->load('Zend/Barcode');
$barcode = $this->input->post('barcode'); //nomor id barcode
$imageResource = Zend_Barcode::factory('code128', 'image', array('text'=>$barcode), array())->render();

$imageName = $barcode.'.jpg';
$imagePath = 'barcode/'; // penyimpanan file barcode
imagejpeg($imageResource, $imagePath.$imageName);
$pathBarcode = $imagePath.$imageName;

$kd_barang = $this->input->post('kd_barang');

$pathBarcode = $this->input->post('barcode');



$editdata=array(
/*Nama Field => $Nama Variabel*/

'barcode' => $pathBarcode
);


/*Primary Key Sebagai Kunci*/
$where=array(
'kd_barang'=>$kd_barang
);
/*Mengambil Function Dari Model*/
$this->m_operator->aksi_update_barang($where,$editdata,'barang');
redirect('c_op/index');


This is my view :

<form action="<?php echo base_url(). 'index.php/c_op/aksi_editbarang'; ?>" method="post">

<center>

<table border="1">
<?php

foreach ($edit->result() as $c)?>
<tr>
<td>Kode Barang</td>
<!-- Primary Key Sebagai Kunci -->
<td><input type="text" name="kd_barang" value="<?php echo $c->kd_barang ?>" readonly></input></td>

<tr>
<td>Barcode</td>
<td><input type="text" name="barcode" value="<?php echo $c->kd_barang ?>" readonly><?php echo $c->barcode;?></td>
</tr>
<tr>
<td><button type="submit">UPDATE</button></td>
</tr>
<?php ?>
</table>

</center>

</form>


But the barcode could not be drawn because it said "A text must be provide to Barcode befeore drawing". But i have already declare that the text for $barcode is $kd_barang.
It's saved to the database but as a text, not as image. Please help me.

var_dump($barcode);

For whatever reason you aren't getting the $barcode value. I suspect the view you posted isn't directly related.

$barcode

The following code will validate input to some degree and fix the path issue.

$this->load->library('zend');
$this->zend->load('Zend/Barcode');
$barcode = $this->input->post('barcode'); //nomor id barcode
$kd_barang = $this->input->post('kd_barang');
if (is_null($barcode) || is_null($kd_barang))
show_error('Missing parameters');

// make barcode
$imageResource = Zend_Barcode::factory('code128', 'image', array('text' => $barcode), array())->render();
$imageName = $barcode . '.jpg';
$imagePath = 'barcode/'; // penyimpanan file barcode
imagejpeg($imageResource, $imagePath . $imageName);
$pathBarcode = $imagePath . $imageName;
$editdata = array(
'barcode' => $pathBarcode
);
$where = array(
'kd_barang' => $kd_barang
);
$this->m_operator->aksi_update_barang($where, $editdata, 'barang');
//redirect('c_op/index'); commented out for debugging
