I'm trying to figure out something. I found some calendar making code. For each table cell, I want to add <a href="">$day</a> around $day if an entry exists in $db.$table $sql = 'SELECT * FROM '.$db.'.'.$table.' where eventid like '.$eventid.';'; if ($sql ??) This will do:

if ($sql) Best Bao

{echo "<td><a href=\"\">$day</a></td>"; }else{ echo "<td>$day</td>"; } How do I code to know if $sql has returned something? Thanks, John P.S. Greg, Thanks. I'm going to try to do this on my own. If not, I will look at that. Thanks much for the reply.
