Question

为什么我无法将数据保存到数据库？我手动检查每行代码，但没有任何内容抛给数据库。另一件事它没有显示任何错误。

最后一次它还在工作但在我将<input type= text name=firstname...>附加到<div></div>以及其他输入文本之后......最终没有任何事情发生..

Answer 1

您正在检查是否设置了$ _POST ['pawnshopName']，而不是。您应该将其更改为$ _POST ['businessName']。或者，您可以使用name =“businessName”将输入字段更改为name =“pawnshopName”。

为什么我不能使用PHP和HTML将数据保存到MySQL数据库？
