Как то так

Roma32, Непомогло , выбило другую ошибку. Там тот же код , его исправил , белый экран
Добавлено 23.04.15 в 16:44:20:
function num_rows($query_id = '')
{

if ($query_id == '') $query_id = $this->query_id;

return mysql_num_rows($query_id);
}






Код




return mysql_num_rows($query_id); // Ошибка

Спасибо , ответ был пуст

function num_rows($query_id = '')
{

if ($query_id == '') $query_id = $this->query_id;

return mysql_num_rows($query_id);
}







Где тут может быть баг ?
Ошибка :
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in там то там то
