Have a read here: http://php.net/manual/en/mysqli.prepare.php prepare you get a false if it fails. Hence your error.

The issue is your SQL your need to use ? in place of variable names and prepare expects the data to bind. I believe you want:

$sql = "SELECT * FROM posts WHERE date >= ? AND date <= ? ORDER BY date DESC";
$stmt->bind_param('ii', $from, $to);
