So, I'd like to make a loop that loops through the results from the following code:
$check_events = "SELECT * FROM events_meedoen WHERE username=:username";
$stmt_check = $db->prepare($check_events);
$stmt_check->bindParam(':username', $username);
$stmt_check->execute();
$events_row = $stmt_check->fetch(PDO::FETCH_BOTH);
$event_id = $events_row['event_id'];
$get_event = "SELECT * FROM agenda WHERE event_id=:event_id";
$stmt = $db->prepare($get_event);
$stmt->bindParam(':event_id', $event_id);
$stmt->execute();
So, for example, I'd like to get all results with the $event_id
gotten by checking the agenda for all events that the user is signed up for.
This should result in 2 for my account, which it does not because it only checks once. Any help? :)
you need to put your call to fetch
in a while loop. As you can see from the docs , PDO::fetch
calls the next record from the result set.
so, something like this will loop through all of the results:
while($events_row = $stmt_check->fetch(PDO::FETCH_BOTH)) {
$event_id = $events_row['event_id'];
// do something with the $events_row array here
}
because PDO::fetch
returns false
when it hits the end of the result set, the while loop knows when to stop.
