kaya po yan ng error boss kasi yung $_GET['id'] is based sa url ng page.
ito po example

http://www.symbianize.com/showthread.php?id=1432868

tapos kapag sa page mo may naka lagay na
$id = $_GET['id'];
then yung $id = '1432868'

pero since may error na undefined index, means walang id sa URL part

kasi yung GET is kumukuha ng value galing sa URL.

try nyo po gawing
$id = '1'; // or any value na meron sa database table mo

dba mawawala yung undefined error.

hope this helps. hehe senxa medyo matagal na hindi humahawak ng php
 
try this..

Code: 
$id= (!empty($_GET['id'] )? $_GET['id']: null);

actually, mas appropriate yung isset() kesa empty() / !empty,

empty = present, pero walang laman, kapag absent yung variable, mage-error ka
isset = iccheck muna kung present yung variable
 
Salamat po sa mga nag respond :) subukan ko po yung mga suggestions at tulong nyo po.
 
if(!isset($_GET['id']) || empty($_GET['id']))
{
echo '<div class="container">
<div class="row">
<div class="col-md-12 text-center">
<h4>Sorry! Missing ID!...</h4>
<button type="button" class="btn btn-warning" onClick="javascript:history.go(-1)"> Return to Previous Page </button>
</div>
</div>
</div>';
}else{
$id = trim($_GET['id']);
$id = $conn->real_escape_string($id);
$q = "SELECT * FROM employee WHERE name_id ='".$id."' ";
$result = $conn->query($q);
}
