FROM `tests` 
LIMIT 0 , 30 ");

{
$QQQ4 = 'to come';
}

ok i found this in the manuel

$q = "SELECT * FROM tests";
$res = mysql_query($q);
$row = mysql_fetch_assoc($res);
echo (empty($row['d'])? "empty": "not empty");

works great but i want it to echo the content if there is not not empty

try this

<?php
$QQQ4 = mysql_query("  SELECT *
FROM `tests` 
LIMIT 0 , 30 ");

if(!mysql_num_rows($QQQ4))
{
$QQQ4 = 'to come';
}

i got it going with this.the only think is that it links the empty to...

[code]
$q = "SELECT * FROM tests";
$res = mysql_query($q);
$row = mysql_fetch_assoc($res);


<a href="events.php?id=<?php echo $row['id'] ?>"target="_blank"><? echo (empty($row['evenement'])? "A venir": $row['evenement']);
?></a>
