致命的なエラー: キャッチされない例外 'PDOException' とメッセージ 'SQLSTATE[42000]: 構文エラーまたはアクセス違反: 1064 SQL 構文にエラーがあります。C:\xampp\htdocs\PhpProject1\userv2.php:120 スタック トレース: #0 C: \xampp\htdocs\PhpProject1\userv2.php(120): PDOStatement->execute() #1 C:\xampp\htdocs\PhpProject1\create.php(41): User->Save() #2 {main} がスローされるC:\xampp\htdocs\PhpProject1\userv2.php の 120 行目
ここの投稿のいくつかで提案されているように、列名にバックティックを使用しましたが、エラーを完全に解決するわけではありません。私は同様の投稿を読みましたが、解決策を見つけることができなかったので、あなたの助けのためにエラーとコードをポッティングしています. 前もって感謝します。
