Question

我对此代码有疑问。当我登录它需要它不带我到主页但留在登录页面。我想将用户重定向到（http://localhost/trial/index.php#Home）成功登录后如何修复？

Answer 1

你至少有两个问题：

1 - 最重要的是，您在使用PHP发送一些内容后尝试重定向，这是不允许的：

echo "succes!";
header("Location:#Home");

删除echo行以解决此问题。

2 - 您还需要更新重定向以重定向服务器端的某个位置。 PHP不了解客户端指令，例如页面上的命名锚点（在您的情况下为#Home）

header("Location:#Home");

将此更新为header("Location:index.php#Home");以解决此问题。请注意，如果您的index.php是您的主页，则可能根本不需要#Home。

Answer 2

重定向中的＃符号会导致停留在同一页面上的问题 - 因为这表明它是您已经在的页面中的锚点位置。您需要将其更改为：

try
{
    String id = txtId.Text;
    String name = txtName.Text;
    String tel = txtTel.Text;
    String add = txtAdd.Text;

    String SqlQuery = @"INSERT INTO [Table]
                        VALUES(@id, @name, @tell, @add)";

    using (SqlConnection con = new SqlConnection(conString))
    using (SqlCommand cmnd = new SqlCommand(SqlQuery, con))
    {
        con.Open();

        cmnd.Parameters.Add("@id", SqlDbType.NVarChar).Value = id;
        cmnd.Parameters.Add("@name", SqlDbType.NVarChar).Value = name;
        cmnd.Parameters.Add("@tel", SqlDbType.NVarChar).Value = tel;
        cmnd.Parameters.Add("@add", SqlDbType.NVarChar).Value = add;

        cmnd.ExecuteNonQuery();

        MessageBox.Show("Saved Sucessfully", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message, "Error occurred while saving", MessageBoxButtons.OK, MessageBoxIcon.Information);
}

另外 - 如果您只是想将用户重定向到主页的顶部 - 根本不需要它 - 您只会尝试将它们带到页面下方存在的锚点。如果您试图将它们引导到hte页面的顶部，只需使用没有列出锚点的相对路径：

header("Location: index.php#Home");

Php主页重定向空白
