Adding and viewing comments isn't working for me???

[cturner]

I am trying to add an articleid everytime a comment has been added to a database table then view the comments when an article has selected and it isn't working out for me. It isn't displaying every comments for the particular article. Can someone please help me solve this problem? Thanks in advance. ???

Here is the code for adding the articleid:
[code]
$articleid = mysql_real_escape_string($_GET['articleid']);
// get the user's username that made the comment
$username = mysql_real_escape_string($_COOKIE['username']);
// get the comment from the form
$comment = mysql_real_escape_string($_POST['comment']);
// get today's date
$date_entered = date("j F, Y");
$date = mysql_real_escape_string($date_entered);
// insert the articleid into the commentpost table
$insert = "INSERT INTO `commentpost` (`id`, `articleid`, `comment`, `date_entered`, `username`) VALUES (0, '$articleid', '$comment', '$date', '$username')";

if (mysql_query ($insert)) {
// once the data has been added go to the comment_added page
header ('Location: comment_added.php');
} else {
print "<p>Could not add the entry because: <b>" . mysql_error() .
"</b>. The query was $sql.</p>";
}
mysql_close();
[/code]

Here is the code for viewing the comments:
[code]
$articleid = mysql_real_escape_string($_GET['articleid']);

// select the articleid
$query = "SELECT * FROM `commentpost` WHERE articleid = $articleid";
$result = mysql_query ($query) or die("Could not query because: " . mysql_error());

while($row = mysql_fetch_array($result)) {
// print the comments for that article and the date entered and the username
echo "<br /><br />".$row['date_entered']."<br />".$row['comment']."<br />";
echo $row['username']."<br />";
}
mysql_close();
[/code]
