Question

I need to keep selected the options users choose in a multiple select menu. This is the code I have so far, but still doesnt’ work. Thank you for your help!

<select name="cb_estatura2[]" size="6" multiple="multiple" class="inputbox" id="cb_estatura2">
<?php 
$height = array("57","58","59","60");
$choosen_height = $_GET['cb_estatura2'];

for ($i=0;$i<count($height);$i++) 
     {
      $selected = ($height[$i] == $choosen_height[$i] ? 'selected="selected"' : ''); 
      echo "<option value='$height[$i]' $selected>$height[$i]</option>";
     } 
?>
</select>

The one thing that should work would be this:

<select name="cb_estatura2[]" size="6" multiple="multiple" class="inputbox" id="cb_estatura2">
<?php 
$height = array("57","58","59","60");
$choosen_height = $_GET['cb_estatura2'];

for ($i=0;$i<count($height);$i++) 
     {
      $selected = (in_array($height[$i],$choosen_height) ? 'selected="selected"' : ''); 
      echo "<option value='$height[$i]' $selected>$height[$i]</option>";
     } 
?>
</select>

This should work, just for the fact that the $_GET['cb_estatura2'] doesn’t populate like the $height array. Could be wrong, haven’t tested it.
