I have a php script with this code on it:
<?php
$sql="SELECT * from reminders where duedate < DATE(now()) and dismissed = '' ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
if(mysql_num_rows($rs) > 0)
{
?>
<div class="box">There are overdue reminders. <a href="/admin/reminders/reminders.php?action=overdue">Click Here to view</a></div>
<script type="text/javascript">
window.onload = function()
{
var answer = confirm("You have Overdue Reminders. Would you like to view them?")
if (answer)
{
window.location = "/admin/reminders/reminders.phpaction=overdue";
}
}
</script>
<?php
}
$sql="SELECT * from reminders where duedate = DATE(now()) and dismissed = '' ";
$rs=mysql_query($sql,$conn) or die(mysql_error());
if(mysql_num_rows($rs) > 0)

there are many SQL Queries that query different tables etc, i know you can use if(mysql_num_rows($rs) == 0) { echo 'something here'; }
but that would only be for one of the queries. whats the best way to see if NONE of the queries return any rows to display a message?
