Query koji si izvrsio (ili nisi) nije vratio dobar Resource ID pa samim tim i poziv mysql_fetch_... (Resource ID) ne moze da se izvrsi. Za svaki query vraca se ResourceID, true ili false (resourceID samo za one koji vracaju podatke: SHOW, SELECT..., true za INSERT, UPDATE,... a FALSE u oba slucaja ako nije izvrsen query ili je doslo do bilo kakve mysql greske)
Zato bi bilo sigurnije da pises:
$res = mysql_query (...)
if ($res) {
while ($r = mysql_fetch_assoce ($res))
{
...
}
}
else {
echo "query nije izvrsen";
}
ili koristi cuveno ingeniozno
$res = mysql_query (...) or die ("problem");
ili
$res = mysql_query (...) or print ("problem");
