Question

I’m stuck on a simple MYSQL UPDATE statement; selecting an ID from the database, and then updating a record WHERE ID = $ID. Code:

$searchDates = ('SELECT * FROM booking_event WHERE subject != "Closed" AND is_reminded IS NULL AND DATE_ADD(NOW(), INTERVAL 2 DAY) >= `starting_date_time` AND NOW() <= `starting_date_time`'); 

$result = mysql_query($searchDates) or die (mysql_error());

while ($row = mysql_fetch_array($result)) {
  $id = $row['event_id'];

mysql_query("UPDATE booking_event SET is_reminded = 1 WHERE event_id = '$id'") or die (mysql_error()); 

}

For some reason it won’t update with the ID selected from the database – I’ve tried using a testID variable and it works fine.

Any help would be appreciated
Thanks!

Answer 1

PHP variables are case sensitive. Most likely your column name in MYSQL will be something like Event_Id or any other casing. Using SELECT * will return the actual name, so to fetch it you would need $id = $row['Event_Id'];

Best thing to be sure you dont have a casing problem, use:

SELECT event_id FROM ....

and then $id = $row['event_id']; will work.
