Question

I am making a recurring event system and have to hard code a check to see if an event has passed to make a new one. (No, I can not make a cron job because the system base is Windows and no, I do not have access to the task scheduler.)

This is the code I have so far:

<?php
require('common.php');
$query = "SELECT 
             *
          FROM 
             DD_events
      ";
try{
$stmt = $db->prepare($query);
$result = $stmt->execute();
}
catch(PDOException $ex){
die("Failed to run query: " . $ex->getMessage());
}
$chk = $stmt->fetchall();
//print_r($chk);

foreach ($chk as $chks) {
if (time() > $chks['event_date']) {
//Add 1 day to event time
$time = strtotime($chks['event_date']);
$newTime = $time + 86400; // 24 * 60 * 60

// Create query to make the next event
    $query = "INSERT INTO
            DD_events (event_name, event_date, initiator, min_lvl, max_level)
              VALUES 
            ({$chks['event_name']}, {$newTime}, 0, {$chks['min_lvl']}, {$chks['max_level']})
      ";
    try
    {
        // These two statements run the query against your database table.
        $stmt = $db->prepare($query);
        $stmt->execute();
    }
    catch(PDOException $ex)
    {
        // Note: On a production website, you should not output $ex->getMessage().
        // It may provide an attacker with helpful information about your code. 
        die("Failed to run query: " . $ex->getMessage());
    }
}
}

it returns this error:

Failed to run query: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 200)' at line 4

Can anyone spot the error I am making because I have been looking at it for the past 30 mins and can’t see it.

Answer 1

Perhaps an easier way to do the same thing:

INSERT INTO DD_events
(event_name, event_date, initiator, min_lvl, max_level)
SELECT event_name, DATE_ADD(event_date, INTERVAL 1 DAY), 0, min_lvl, max_lvl
FROM DD_events

This will create a new event for each existing event one day later (which is what you said the code was supposed to do) and eliminates the need for basically your whole script
