Hello.
I think, maybe it's better to use JavaScript in this case. For example, You need:

<form action="..." method=POST>
<select onClick="...">
<option value="1">First</option>
...

<option value="265">Last</option>
</select>
<input type=hidden name="hvalue">
</form>

On every mouse click, You must take selected value and add it to the "hvalue" with JavaScript. You may separate values with ";" (1;256).

Maybe it helps You

Look, my form action=$PHP_SELF

So i want all my field to be refilled but there is a mutlyple select so i can take the $_POST[''] aray but when the page get reloaded then i don;t know how this multiple select mark some of its values selected (something like edition page)

I've tried to execute code like this:

<?php
$testval = trim($_POST["testval"]);
echo "<html>";
echo "<body>";
   if (!empty($testval))
      echo $testval;
   else { 
      echo "<form action='".$PHP_SELF."'> method=POST>";
         echo "<select name='testval' multiple>";
            echo "<option>First</option>";
            echo "<option>Second</option>";
            echo "<option>Third</option>";
         echo "</select>";
         echo "<input type='submit'>"; 
      echo "</form>";
   }
echo "</body>";
echo "</html>";

It returns only the last value I've selected. That's why I offered You to use JavaScript. Because You can analyze $testval (separate values from ";"); And when somebody selects value JavaScript simply add new value to the hidden variable (look below in my first reply). You must reload page only after user clicks button. But when he'll do it who will know all selected values...
