我现在已经搜索了几个小时但仍然遇到了这个问题（这让我发疯了）。正如主题已经说明的那样，我尝试在数据库中插入一行，该数据库失败而没有错误。在phpMyAdmin上执行语句工作正常。
我已在此处找到this question并应用了该解决方案。我怀疑character settings on the database并设置了所有内容（表格加上列加上db到utf8_bin）。我还设置了autocommit to false and I do my own commit。数据库连接就在那里，因为我可以在数据库表上选择几行（下面没有显示）并获得一个不错的结果。我甚至检查过我正在运行该语句（如建议here）。

我总是遇到if-Statement的else-branch，但是没有收到来自$ mysqli-＆gt;错误的错误消息（如suggested here）。任何人都可以给我一些可能出错的提示吗？
