Hi
Anyone have a good idea for a loop that could populate a select list(form) with time values from 08:00 - 18:00 (24h time format) with an interval of 15 min between each <option value> ?
<select name='time'>
<option value='08:00'>08:00</option>
<option value='08:15'>08:15</option>
<option value='08:30'>08:30</option>
...
<option value='18:00'>18:00</option>
</select>Kinda stuck with this one...help would be much appreciated.
Do not know if this is considered as a "good" solution to the problem, but it works for me. Feel free to give me som other alternatives if you have a better way :-)
function make_timelist($preval, $postname){
echo "<select name='".$postname."' class='formstyle'>";
echo "<option value=''>...</option>";
for($x=730; $x<1815; $x=($x+15)){
if($x < 1000){
$val = '0'.$x;
}else $val = $x;
$thistime = substr($val,0,2).":".substr($val,2,2);
echo "<option value='".$thistime."'>".$thistime."</option>";
if(substr($val,2,2)=='45'){
$x = ($x+40);
}//end if
}//end for
echo "</select>";
}//end function make_timelist
Try some arithmetic:
$start = 8*60+0;
$end = 18*60+0;
for($time = $start; $time<=$end; $time += 15)
{
$minute = $time%60;
$hour = ($time-$minute)/60;
echo sprintf('%02d:%02d', $hour, $minute), "\n";
}
(More long-winded than it needs to be so that it's more obvious what's going on. Obviously leaves out further cosmestic stuff.)
Thanks a lot. I agree that this is a far better solution :-)
