The problem lies in this statement: if(!$result1).
Mysqli_query returns returns an object, except when the query fails. The query doesn't fail when the number of found rows is zero. So, if your query is syntactically correct, but there is no data found, $result1 is not false, but an object.
Do a test for $result1->num_rows, like this: if ( 0 === $result1->num_rows ) echo "No data found".
