Is this what you mean?

 

1 = male

2 = female

0 = all?

 

 

if($xx = 0){
     $sql = "SELECT * FROM table WHERE gender = 1 AND gender = 2";
}

If the gender is specified as both, just omit it as a parameter in the query string. Most often if you just build the query string dynamically, you don't need to construct multiple query strings just because the WHERE clause parameters change.

 

// assuming you've already validated/sanitized the value of $_POST['gender']
$gender = $_POST['gender'] == 'both' ? '' : "AND gender = '{$_POST['gender']}";
$query = "SELECT field FROM table WHERE a.active = 0 $gender";
