Hi.Supose you have this in a form:
<select name=selcolor multi>
<option value=yellow>Yellow</option>
<option value=red>Red</option>
</select>
Now if the both items are selected you will get an array.You can retrive the values like this.
$my_colors=$HTTP_GET_VARS['selcolor'];
if(is_array($my_colors))
{
//enumerate them
foreach($my_colors as $key => $val)
{
echo $key+1." is" $val,"<br>";
}
}
else
{
//we have only one selected
echo "selected one option color :". $my_color;
}
Hope to help.
