Question

您好我正在尝试创建一个评论PHP页面。但是数据库似乎没有链接到php页面。我已经三次检查了我的数据库信息，这绝对是正确的，但似乎无法允许用户提交评论。当您将文本放入框中并按提交页面时，只需重新加载，当我检查应该包含所有添加的注释的表时，它是空白的，就像我的代码中没有正确请求数据库一样？我不确定这是不是问题，因为我对PHP和数据库都很新！有谁知道我可能做错了什么？

数据库看起来像这样

名称类型归类空缺省额外

ID int（11）否无AUTO_INCREMENT
userID int（11）是NULL
profileID int（11）是NULL
评论文字utf8_general_ci否无
情绪int（11）是NULL
commDate timestamp否CURRENT_TIMESTAMP
