Hi
I am not sure I am approaching this correctly.
I need to increment the appointment time by 15 mins for each loop.
This is would be the correct result:
13:00, 13:15, 13:30, 13:45, 14:00,
This is what I am getting:
13:15, 13:15, 13:15, 13:15, 13:15
The user selects the first appointment example 13:00:00 hrs (HH:MM)
and one or more time blocks. Time blocks range from 1 to 10. Each is 0.15 mins (H).
$event_time = 13:00;//start time
$time_block = 5;// number of loops
$event_length = 0.15;//start time increment by

Hi
Thanks for the response.
This is the solution:
[PHP]
$event_time = "13:00";
$time_block = 5;
$event_length = 15; // minutes
for($i = 0, $eTime = strtotime($event_time);
$i < $time_block;
$i++, $eTime = strtotime("+$event_length minutes", $eTime))
{
$new_event_time = date('H:i', $eTime);
echo "<p>$new_event_time</p>\n";
}
[/PHP]
