Hi

I have one more problem

I have 2 tables:

Articles with fields aid, title, intro, content, timestamp

and

Comments with fields commentid, aid, poster, content, timestamp

Now, I want to print out titles of recently commented articles (unique).

Here is what I have so far:

Code: Select all

<ul>
<? $result = mysql_query("SELECT DISTINCT aid FROM comments ORDER BY commentid DESC LIMIT 0, 10") or die(mysql_error());
while($row = mysql_fetch_array($result)) {
$caid = $row['aid'];
		$art= mysql_query("SELECT title FROM articles WHERE aid='$caid'");
		$clanek = mysql_fetch_row($art);
		$title= $art[0];
?>
	<li><a href="<? echo $row['aid']; ?>-a.html"><? echo stripslashes($title); ?></a></li>
	<? } ?>
</ul>
