    Pretty popular question on SO. It means your query failed, so $result is false.

    Add 

    if (!$result){
    echo mysql_error();
}

    To see what exactly error was. Most probably you have some illegal characters in $name variable. So, before embedding it into query string, you need to mysql_escape_string() it.

    $name= mysql_escape_string($name);

    Btw, your code is subject to SQL-injection. So, you’d better use prepared_statements
