Selective database query variable use

Hi folks, I was wanting to create a MySQL database query where if a person enters a specific value in a box, that is passed to the query to search a field. In addition, if the person selects "all" from the box, I would like the query to change to select all rows from the field. Is there a simple way to do this?

One guy suggested something like this, but Im not sure how it works. Help appreciated, Doug

php Code:

Original - php Code
$query = "SELECT * FROM table1"; unset($constraint); if ($field2 != "all") $constraint[] = "field2 = '$field2'" if (isset($constraint)) $query .= " WHERE " . join(" AND ", $constraint);

$query = "SELECT * FROM table1";
 
unset($constraint);
if ($field2 != "all") $constraint[] = "field2 = '$field2'"
 
if (isset($constraint))
    $query .= " WHERE " . join(" AND ", $constraint);
