hi im trying to remove articles from a database
what i do is retrive the list turn them into links

and when you click the link that article will be removed from the table

here is the code

$query = mysql_query("SELECT * FROM Articles");

while($queryresult = mysql_fetch_array($query))
{
	$articleid = $queryresult["ID"];
	$headline = $queryresult["headline"];
	$body = $queryresult["body"];
	$date = $queryresult["date"];
	$staffid = $queryresult["staffid"];

$listofarticles .= "<li><a href=\"index.php?id=" . $articleid . "\">" . $headline . "</a></li>";
}

	if($_GET["id"])
	{

	mysql_query("DELETE FROM Articles WHERE class_id = '" . id ."'");
	$statement= 'articlet deleted';
}else{

?>
	<h1>Political Science Data Base</h1>

	<form>
		<input type="button" onClick="window.location='index.php'" value="main menu" />
	</form>

	<h4>List of Articles</h4>

	<?php echo $statement; ?>
	<?php echo $listofarticles; ?>

<?php } ?>

im not sure if i am even using the right code

change this line...

mysql_query("DELETE FROM Articles WHERE class_id = '" . id ."'");

to...

mysql_query("DELETE FROM Articles WHERE class_id = '" . $_GET['id'] ."'");

As an addendum, make sure your syntax reflects the case of your field names - you use both ID and id, which is it?

To keep your code a lil smaller, you could also create (as you did in the first snippet)
$id = $_GET['id'], then make your query "DELETE FROM Articles where class_id = '$id'"
