mysqli_stmt :: bind_param(): Liczba elementów w łańcuchu definicji typu nie zgadza się z liczbą zmiennych wiążących

Question

Mam więc masywne zapytanie wywołujące ból głowy, które muszę wykonać, włączając w to dane wejściowe, które należy wstrzyknąć do baza danych za pomocą przygotowanych instrukcji mysqli.

Problem, na który napotykam, polega na tym, że liczba zmiennych, które próbuję wywołać bind_param, nie pasuje do # "" tych "", których używam. Policzyłem kilkanaście razy i nie widzę, gdzie się tu mylę. Jest 65 zmiennych i 65 "s".

Czy ktoś może zobaczyć coś, czego mi brakuje? Czy może używam metody bind_param w niewłaściwy sposób?

Answer 1

Znaki w ciągu nie powinny być oddzielone przecinkami:

$stmt->bind_param("sss...", /* variables */); 

Można zobaczyć ten format wykazano w przykładach na the manual page.

Answer 2

Istnieje 65 ciągów znaków, więc jeśli istnieją 65 s, to masz poprawną liczbę. Jednak błędy pojawiają się, ponieważ rozdzieliłeś litery s przecinkami. Zamiast $stmt->bind_param("s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s..." powinno być

$stmt->bind_param("sssssssssssssssss..." 

To powinno rozwiązać swoje błędy.
