[PHP-DB] SQL Query - Using variable from another SQL Query

[Matthew Ferry]

Hello Everyone....

Got a simple / stupid question.
Worked on this all night. I'm over looking something very basic here.

The query "event_time" brings back the calendar id for each event that is 
pending in the future.
ie.... 12, 13, 14, 26  (There could be 100 of them out there)

The second query "events" needs to meet both reqirements.  
 1 - cal_category='501' 
 2 - cal_id= a number from the "event_time" query

I think i need to do a loop inside of a loop

Thanks...

Here is my code: 

<?php

$todays_year = date("Y");

$todays_month = date("m");

$todays_day = date("d");

$tstamp = mktime(0, 0, 0, $todays_month, $todays_day, $todays_year);

$event_time = mysql_query("SELECT cal_id FROM egw_cal_dates where cal_start > 
$tstamp", $db);

$events = mysql_query("SELECT * FROM egw_cal WHERE cal_category='501' and 
cal_id='$event_time'\n", $db);



if ($event = mysql_fetch_array($events)) {

echo "<center>\n";

echo "<HR>\n";

do {

echo "<B><Font 
Size='10'>$event[cal_title]&nbsp;&nbsp;&nbsp;&nbsp;-&nbsp;&nbsp;&nbsp;$event[cal_location]</B></Font>\n";

echo "<BR>\n";

echo "$event[cal_description]";

echo "<BR>\n";

echo "<HR>\n";

} while ($event = mysql_fetch_array($events));

} else {

echo "No Public Events Are Currently Scheduled...";

}

?>
