与状态和分页mysql的问题

我打电话给一个mysql查询，作为不同的结果（关闭打开，挂起，所有）和分页的各种不同的状态，一切都很好，除了当我点击下一页链接或任何其他页面我失去了状态设置，例如“关闭”，并显示所有结果。与状态和分页mysql的问题

我是一个PHP和MySQL的新手，所以不真的没有如何实现这个，以便以某种方式存储一个会话，以便一旦分页被使用，状态仍然被设置。

请参阅代码。

任何帮助真的很感激。

这里的解决方案是将您的$viewstate传递给您的所有分页链接。示例前一个链接，添加&viewstate=$viewstate

if ($current_page != 1) { 
     echo '<a href="?page_id=1072&amp;startoftable=' . ($start - $display) . '&np=' . $num_pages . '&viewstate=' .$viewstate. '">Previous</a> '; 
    }

然后，在您的视图状态设置代码，添加$ _GET到你的条件，因此可以判断什么是当前视图状态。

/* View state set code */ 

if (isset($_POST['showopen']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'open')) { 
    $viewstate='open'; 
} 

if (isset($_POST['showpending']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'pending')) { 
    $viewstate='pending'; 
} 


if (isset($_POST['showclosed']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'closed')) { 
    $viewstate='closed'; 
} 

if (isset($_POST['show_all']) || (isset($_GET['viewstate']) && $_GET['viewstate'] == 'all')) { 
    $viewstate='all'; 
}

希望这项工作。

嗨，非常感谢，非常感谢。但现在一个小问题是我需要解决如何删除np（页数）的查询字符串，并在点击新状态后开始行。如果您在页面3上并单击另一个只有一页结果的状态，则由于查询字符串显示页面3 = 12的开始，您将得不到结果。希望是有道理的。你有什么想法？ – Maximus

我认为你需要计算某个视图状态有多少记录。因此，如果记录数小于页面，请将其设置为第1页。 – ace

使用$ _SERVER ['REQUEST_URI'] = preg_replace（'！＆startoftable =。*！'，''，$ _SERVER ['REQUEST_URI']]破解它）; – Maximus
