I am following this thread because I am trying to do something simular.
That is pass value back to php on a select ONCHANGE=. Problem is I do
not know php\javascript all that well. I had posted my code to this
newsgroup but received no answer. So I do not know if I can do what I am
trying to do or I am just so far off that it does not warent an answer.
This is what I have so far. I can not get to work and have comment out
what I am trying:

//
// Handle the data coming back
echo '<FORM NAME=author method=post action='.$_SERVER['PHP_SELF'].'>';
//echo '<SELECT NAME=author_pk SIZE=20 COLS=20 ONCHANGE='.$_POST[id].'>';
//echo '<SELECT NAME=author_pk SIZE=20 COLS=20 ONCHANGE=getPK()>';
echo '<SELECT NAME=author_pk SIZE=20 COLS=20>';

while ($rows = mysql_fetch_object($result)) {
echo '<OPTION VALUE='.$rows->id.'>'.
$rows->TITLE.' '.
$rows->lastname.', '.
$rows->firstname.
$rows->middlename.
$rows->SUFFIX.
'</OPTION>';
}
echo '</SELECT>';
echo '</FORM>';
//echo '<script language=Javascript>';
//echo 'function getPK() {';
//echo
"document.author.author_pk.options[document.author.author_pk.selectedIndex].value
";
//echo '}';
//echo "</script>";
