<option value="23:00:00">23:00:00</option>
<option value="23:30:00">23:30:00</option>
</select>
Is there a way to make it a little bit more dynamic, instead of having this huge html ?
Something like this
<?php foreach (date('H:i:s') as $time): ?>
<option value="<?php echo $time; ?>"><?php echo $time; ?></option>
<?php endforeach; ?>

Answer 1

You can use while loop to make it,
<?php
$start = "00:00"; //you can write here 00:00:00 but not need to it
$end = "23:30";
$tStart = strtotime($start);
$tEnd = strtotime($end);
$tNow = $tStart;
echo '<select name="schedule_time">';
while($tNow <= $tEnd){
echo '<option value="'.date("H:i:s",$tNow).'">'.date("H:i:s",$tNow).'</option>';
$tNow = strtotime('+30 minutes',$tNow);
}
echo '</select>';
?>

Answer 2

Best and simplest method:
<select>
<?php
for($hours=0; $hours<24; $hours++)
{
for($mins=0; $mins<60; $mins+=30)
{
$time = str_pad($hours,2,'0',STR_PAD_LEFT).':'.str_pad($mins,2,'0',STR_PAD_LEFT).':00';
echo '<option value= "'.$time.'">'.$time.'</option>';
}
}
?>
</select>

Answer 3

hey you can try this code, you can take whatever range $start and $end variable .
<?php
$start = "12:00:00";
$end = "24:00:00";
$tStart = strtotime($start);
$tEnd = strtotime($end);
$tNow = $tStart;
?>
<select name="schedule_time">
<?php
while($tNow <= $tEnd){ ?>
<option value="<?php echo date("H:i:s",$tNow); ?>"> <?php echo date("H:i:s",$tNow);?></option>
<?php
$tNow = strtotime('+30 minutes',$tNow);
}
?>

Answer 4

Try with this code.
<?php
$start = '00:00AM';
$end = '11:59PM';
$interval = '+30 minutes';
$now_str = strtotime($start);
$end_str = strtotime($end);
echo '<select name="schedule_time">';
while($now_str <= $end_str){
?>
<option value="<?php echo date('H:i A', $now_str);?>" ><?php echo date('H:i A', $now_str);?></option>
<?php
}
echo '</select>';
?>
