Yes. The values must be passed as an array. In order to do that the select
tag requires the [] braces. The proper syntax is:
<select name="my_select[]" multiple>
<option>One</option>
<option>Two</option>
<option>Three</option>
</select>
<?
// To read the selected items...
for($i=0; $i<count($_POST['my_select']); $i++)
{
echo $_POST['my_select'][$i]."<br>";
}
?>
Hope that helps.
