mysqli_stmt :: bind_param（）：型定義文字列の要素の数がバインド変数の数と一致しない

ですから、mysqliで準備されたステートメントを使用してデータベースに注入する必要のある65フォーム入力を含む、実行する必要があるこの大きな頭痛を引き起こすクエリがあります。

私が実行している問題は、それが私が呼び出そうとしている変数の数を示しているということですbind_param onは、使用している「s」の数と一致しません。 私は十数回数えましたそして、私がここでどこが間違っているのかわかりません。 65個の変数と65個の「s」があります。

誰かが私が行方不明のものを見ることができますか？または、おそらくbind_paramメソッドを誤った方法で使用していますか？

文字列内の文字はコンマで区切られてはなりません：

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

manページ の例に示されているこのフォーマットを確認できます。

65個の文字列パラメータがあるので、65個ある場合は正しい数になります。ただし、sをカンマで区切っているため、エラーが表示されています。の代わりに $stmt->bind_param("s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s,s..." そのはず

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

これでエラーが解決します。

bind_paramの文字はコンマで区切ってはいけません。

2つの変数をバインドする必要がある場合は、次のようにします。

$stmt->bind_param('ss', $firstvariable, $secondvariable);
