I am having an error in the PHP code saying "Notice: Undefined index".
The code:
<?php require_once('../Connections/itemconn.php'); ?>
<?php
$id=$_GET['id'];
$query=mysql_query("select * from manuf where id='$id' ")or die(mysql_error());
$row=mysql_fetch_array($query);
?>
<form action="updateprice.php" method="post" enctype="multipart/form-data">
<table align="center">
<tr>
<td> <label><strong>Item Name</strong></label></td>
<td> <label> <?php echo $row['itemname']; ?></label><input type="hidden" name="id" value="<?php echo $id; ?> " />
<br /></td>
</tr>
<tr>
<td><label><strong>Unit price </strong></label></td>
<td> <input type="text" name="pass" value="<?php echo $row['unitprice']; ?> " /><br /></td>
</tr>
<tr>
<td>
<input type="reset" name="Reset" value="CANCEL" />
<br></td>
<td>
<input type="submit" name="Submit2" value="Update" /> </td>
</tr>
</table>
</form>
</body>
</html>
As I am a beginner I cant solve this issue. Can someone help me with this?
