Hi there, is there a simpler way of writing the below?

   
<option <? if ($nights == "1") echo "selected=\"selected\""; ?> value="1">1</option>
  	<option <? if ($nights == "2") echo "selected=\"selected\""; ?> value="2">2</option>
  	<option <? if ($nights == "3") echo "selected=\"selected\""; ?> value="3">3</option>
  	<option <? if ($nights == "4") echo "selected=\"selected\""; ?> value="4">4</option>
  	<option <? if ($nights == "5") echo "selected=\"selected\""; ?> value="5">5</option>
  	<option <? if ($nights == "6") echo "selected=\"selected\""; ?> value="6">6</option>

Dear,

Something like :

if($nights=="")
{
$nights = 7;
}

for($j=0; $j <= 7 ; $j++){
if ($nights == $j)
{
echo"<option value='".$j."'>".$j."</option>";
}
else
     {
     echo"<option value='".$j."' selected=\"selected\">".$j."</option>";
     }
}

You can use jquery to select the option.

<select name="select_box_name" id="select_box_name">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
</select>
<script type="text/javascript" language="javascript">
      $("select#select_box_name option[value='<?php echo $nights;?>']").attr("selected", "selected");
</script>

if($nights==""){$nights = 7;}

for($j=0; $j <= 7 ; $j++){
if ($nights == $j)
{
echo"<option value='".$j."' selected=\"selected\">".$j."</option>";
}
else
     {
     echo"<option value='".$j."'>".$j."</option>";

Hi GamesNET2,

Please refer to the following code.Please note that the loop should be start from 1 and end by 6.

<?php
$nights = isset($night)?$night:7;
$str_selected = '';
echo '<select name="select_night">';
for($i = 1; $i<=6;$i++){
      if($nights == $i)  $str_selected = 'selected';                  
      else $str_selected = '';
      ?>
            <option value="<?php echo $i;?>" <?php echo $str_selected;?>  ><?php echo $i?></option>
      <?php
}
echo '</select>';
