Steve,
These can be a PITA. Here's how I've done it.
1. Create a function to determine which is selected:
function is_selected( $option_expression )
{
if ($option_expression)
{
$retval = "selected";
}
else
{
$retval = "";
}
return $retval;
} // end of function is_selected
2. Build your list of selection, in this case a list of classifications
fetched from a database;
$option_class is the variable holding the list of options:
$sql = "select * from class";
$result = mysql_query( $sql );
while( $row = mysql_fetch_array( $result ) )
{
$nClassKey = $row["nClassKey"];
$cClass = $row["cClass"];
$selectval = is_selected( $nClassKey == $nClass );
$option_class .= "<option value = \"$nClassKey\"
$selectval >$cClass</option>";
} // end while $row = mysql_fetch...
3. Then display it this way in the form:
<Select name="nClass">
<? echo $option_class ?>
</select>
Hope this is helpful - Miles
