$_GET problems...

[jwwceo]

I'm trying to make a page to update or delete a shirt from a database. I am passing the shirt_id in through a URL link and using GET. I used the exact same GET code on another page and it worked fine.  Can anyone see anything wrong with this... I am getting this error

Undefined index: shirt_id in E:\ProgramFiles\Apache\htdocs\ShirtSite\edit.php on line 15

Thanks in advance!!!!

<?php

include 'library/config.php';
include 'library/opendb.php';

$shirt_id = $_GET['shirt_id'];  [b]//LINE 15[/b]

if(isset($_POST['delete'])) {

$query = "DELETE FROM shirts WHERE shirt_id='$shirt_id'";
$delete = mysql_query($query) or die("Error: ". mysql_error(). " with query ". $query);
    echo "Your shirt has been deleted!";

}



else if(isset($_POST['submit'])) {

  $name=$_POST['name'];
  $comment=$_POST['comment'];
  $link=$_POST['link'];
  $site=$_POST['site'];
  $image=$_POST['image'];
  $active=$_POST['active'];
  $commission=$_POST['commission'];

  $query="UPDATE shirts SET name='$name', comment='$comment', link='$link', site ='$site',
  image ='$image', active ='$active', commission ='$commission' WHERE shirt_id ='$shirt_id'";

  $result = mysql_query($query) or die("Error: ". mysql_error(). " with query ". $query);
    echo "Your shirt has been updated!";


} else

{


$data = mysql_query("SELECT * FROM shirts WHERE shirt_id ='$shirt_id'") or die(mysql_error());
$info = mysql_fetch_array( $data );

it's not an error, it's a warning.  You can simply reduce the error_reporting level to get rid of it.

Will the code work if I change the error level...as of right now, the code doesn't do what it's supposed to do. it doesn't update the database when the submit button is pressed...I get the warning only...

can I change the code to get rid of the warning?

try to change
<form method='post' action='edit.php'>
to
<form method='post' action=''>
or
<form method='post' action='edit.php?shirt_id=$shirt_id'>
