PHP Add Image Upload to Existing Form

Hi all,

I need to add image upload functionality to my existing form.

Can anyone help?

Here is the current code:

//index.php

//form part

<form method="post" name="formBarang" action="process.php" id="formBarang">
<table width="400">
<tr>
<td>ID</td><td><input type="text" name="id" size="10" value="<?php echo $id;?>" readonly="Yes" /></td>
</tr>
<tr>
<td>Name</td><td><input type="text" name="name" size="50" value="<?php echo $name;?>" /></td>
</tr>

<tr>
<td>Short Description</td><td><input type="text" name="short_desc" size="50" value="<?php echo $short_desc;?>" /></td>
</tr>
<tr>
<td>Price</td><td><input type="text" name="price" size="10" value="<?php echo $price;?>" /></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="<?php echo $status;?>"</td>
</tr>
</table>
<input type="hidden" name="action" value="<?php echo $action;?>" />

</form>


//Process.php
<?php


include("conn.php");
if(isset($_POST))
{
$action=$_POST['action'];
$id=$_POST['id'];
$name=$_POST['name'];
$price=$_POST['price'];
$short_desc=$_POST['short_desc'];
}
if($action=="new")
{
$check=mysql_query("select * from tbl_barang where id='$id'");
if(mysql_num_rows($check)==0)
{

mysql_query("insert into tbl_barang(id,name,short_desc,price) values('$id','$name',$short_desc','$price')") or die("data cannot be inserted");
echo 1;
}
else
{
echo "code cannot be nothing";
}
exit;
}
elseif($action=="update")
{
mysql_query("update tbl_barang set name='$name',short_desc='$short_desc',price='$price' where id='$id'") or die ("data cannot be updated");
echo 1 ;


exit;
}
elseif($_GET['action']=="delete")
{
$id=intval($_GET['id']);
mysql_query("delete from tbl_barang where id='$id'")or die("Cannot Delete record");
echo 1;
exit;
}

?>


Hope someone can help.

Thanks
