I would do it another way.
say you have all the possible choices in an array that come out of a
database, and ypou want, if the user already selected one, this one to
be selected, right?
Then i would set the selected atribute only if the value out of the
database is the same as the one submitted by the form:
like this (omitting the surrounding html):
$query= "select distinct * from sometable";
$result=mysql_query($query);
// the select field is named selectfield,
echo "<form name=\"myform\" action=\"$PHP_SELF\" Method=\"post\">";
echo "<select name=\"selectfield\">";
// the variable $selectfield is, if set the value submitted by the form
$selectfield = $_POST["selectfield"];
while ($row=mysql_fetch_array($result)){
echo "<option";
// assuming the second element of this array holds your
// choices then
if($selectfield == $row[1]){
echo " selected";
}
echo ">" . $row[1] . "</option>\n";
}
echo "</select>"
echo "<input type=\"submit\">\n";
echo "</form>";
i think this is a more straightforward solution for your problem...
