Question

I want to create a menu from category names in database, so far I have this:

$list  = "SELECT category FROM posts";
$rlist = mysql_query($list) or die(mysql_error());

while($rows = mysql_fetch_assoc($rlist)) 
 { 
 $catname = $rows['category'];
 echo '<li><a href="' . $url . '/index.php?cat=' . $catname . '">' . $catname . '</a></li>';
} 

Which lists everything but I need to make each only list once so its a menu.

Answer 1

Maybe you want

SELECT DISTINCT category FROM posts;

And assuming you want them ordered

SELECT DISTINCT category FROM posts ORDER BY category ;
