我不确定为什么我的数据库没有从我的网站接收信息。此外，没有弹出错误消息，所以我根本不确定数据是否在任何地方。它似乎允许我连接到数据库，但当我单击"添加员工"时，我只得到一个空白页面。有什么建议吗？编辑：我已经将代码更改为只输入一个变量，但仍然只返回一个空白页。

$sql = "INSERT INTO employee ". "(employee_name) ". "VALUES('$emp_name', NOW())";
您在sql中传递了两个值，但只指定了一列。employee_name
您可能需要删除NOW（）值或添加另一列（employee_name，date_aded）
$sql = "INSERT INTO employee ". "(employee_name) ". "VALUES('$emp_name')";
$sql = "INSERT INTO employee ". "(employee_name, date_added) ". "VALUES('$emp_name', NOW())";
