【问题描述】：
大家好，我正在尝试过滤表格，然后将过滤后的表格打印为 pdf。
我输入了其他代码，但这已经接近完成了。
我尝试了不同的解决方案，但似乎无法解决。
如果你们对如何做到这一点有任何建议，请说。任何帮助都会很棒。
帮助大家！提前致谢！
这是reportss.php

$result = mysqli_query($conn, $sql);
while($row = mysqli_fetch_array($result))

$output .= '<tr>

【问题讨论】：
-
filterss.php是您的问题文本中的错字吗？因为在您的代码中包含filters.php并且在该文件中您有注释//filter.php -
是名为filters.php（如包含）或filters.php（如文中给出）的文件？
-
@James 抱歉忘记删除评论及其只是 filters.php

如果您刚刚开始使用 PHP 并想要构建应用程序，我还强烈建议您查看各种 development frameworks 以查看是否可以找到适合您的风格和需求的。它们有多种风格，从 Fat-Free Framework 这样的轻量级到像 Laravel 这样的更全面。这些为您提供了具体的示例，以及关于如何编写代码和组织文件的更有力的指导。你这里的代码很混乱。
