Question

I want to display a tag with a selected option, which would come from a database.
This is my code:

<?
function check($opt) {
    if ($rows['fa'] = $opt) {
        echo " selected='selected'";
    }
}
echo $fa;
?>

<select name="opt" id="opt">
    <option value="o1"<? check('o1'); ?>>Option1</option>
    <option value="o2"<? check('o2'); ?>>Option2</option>
</select>

The problem is that the function doesn’t work with $rows[‘$fa’], and it works if I just type either “o1”, or “o2”.
If I echo $fa, it gives me the result (“o1″, or”o2”) from the database.

Answer 1

If the data of row is on $fa, set as global, please attention to the scope, the comparison (==):

<?
function check($opt) {
   global $fa;
   if ($fa == $opt) {
      echo " selected='selected'";
   }
}
echo $fa;
?>
