Php 无法更新codeigniter中数据库中的字段

我正在尝试创建更新用户详细信息的函数。但是模型中的数据库事务失败。它只是弹出失败消息，没有给出任何数据库错误或任何东西

有没有一种方法可以查看db日志以便在控制器中的var_dump之类的模型中进行调试

错误发生在哪里？哪一行？它不显示任何行，只是弹出失败消息，这是**if（$this->medit\u account->update\u user（$userid，$array1））**中if条件的另一部分@paskl您的方法“update_user”不返回任何值，这意味着在条件下调用永远不会工作。因此你总是在“其他”中。如果什么都没发生，你检查过数据库吗？你真的需要一个事务吗？如果是，那么您需要结束它——查看codeigniter手册中的代码行。还请记住，您可以使用if$this->db->impacted_rows（）==“1”检查是否有更新，但如果您发送重复信息（如数据库中没有任何内容实际随更新而更改），则这将是错误的。即使删除了事务开始，也会发生同样的情况，检查了手册中的更新代码，我没有看到任何错误。数据库条目中没有任何更改@红花
