无法在网页中显示来自mysql的两个数据库

我无法在网页中显示我的两个数据库。我有一个数据库，用户可以在其中创建一个称为“票证”的新“票证”，当该票证标记为“待处理”时，它将数据库条目移至一个名为“ out_tickets”的新数据库表中。因此，在我的index.php页面上，我像仪表板视图一样显示新的“票证”以及显示“待处理”票证。但是现在我正在努力在index.php上显示数据库中的“待处理”票证结果。

这是我的代码：

 mysqli_error($link);
                }

                // Close connection
                mysqli_close($link);
                ?>
            </div>
        </div>        
    </div>
</div>

如您所见，第一个$sql = "SELECT * FROM tickets"; 可以，但是这个不$sql = "SELECT * FROM out_tickets";

我在MySQL中有这两个数据库，可以从PHPmyAdmin查看它们中的数据

这是我得到的错误：

Warning: mysqli_query(): Couldn't fetch mysqli in 
C:\index.php on line 211

Warning: mysqli_error(): Couldn't fetch mysqli in 
C:\index.php on line 254

ERROR: Could not able to execute SELECT * FROM out_tickets. 

Warning: mysqli_close(): Couldn't fetch mysqli in 
C:\index.php on line 258

2 个答案:

答案 0 :(得分：1)

我认为您的config.php仅连接到第一个数据库。您可以简单地在另一个数据库中设置另一个连接字符串，将其命名为$ link_2并在从out_tickets查询时使用$ link_2

答案 1 :(得分：0)

您介绍了两个带有特定表的数据库。从您的代码中，我可以看到SELECT * FROM out_tickets等于require_once 'config.php';行。您必须连接到另一个数据库（根据您的判断）。
