Answer 1

id recommend either building your options first then appending them to your echo string like so:

$optionString = '';
for ( $i = $data['timeh']; $i <=24; $i++ ){
 $optionString .= "<option ...>".$i."</option>";
}

or making 2 echos to open and close the select and a loop with the option echo in the middle eg

echo "<select ...>";

for ( $i = $data['timeh']; $i <=24; $i++ ){
 echo "<option ...>".$i."</option>";
}

echo "</select>";

try this..

echo "<select class='formfield_select'   name='return_pickuptime_hh' id='rhh' >
                  <option value='' selected='selected' >Hour</option>
                  ";


                  for($i=0;$i<=24;$i++) 
                  {

                  echo "<option value=$i>$i</option>";

                   } 

                echo "</select>";
