Php在页面切换上保留数据过滤器

在分页模板上，除了在有页面切换时重置tsql过滤器外，其他一切都可以完美地工作

    session_start(); // initiate session

/*
    Place code to connect to your DB here.
*/

   First get total number of rows in data table. 
   If you have a WHERE clause in your query, make sure you mirror it here.

我尝试了会话来保持数据过滤器变量，但是当页面移动时，重置总是发生

任何想法都将不胜感激。

您将源查询存储在会话$\u session['sql\u src']=$sql；但在以后的请求中，您永远不会检查它

尝试：

更新：

在再次阅读您的代码后，我可以看到您只是在一篇文章上进行搜索。只有您的初始请求将是一篇帖子，所有其他来自点击寻呼机的请求都将是GETs。上述代码确实说明了这一点。

谢谢。代码运行正常，但在第一次点击页面时，以及在过滤数据时，页面按钮丢失。

if(isset($_POST['search'])){
    $sql = "SELECT * FROM $tbl_name WHERE s_educ01='".  $_SESSION['s_educ01']. "' LIMIT $start, $limit" ;
}else{
    if(isset($_SESSION['sql_src'])){
         $sql = $_SESSION['sql_src']; 
    }else{
        $sql =    "SELECT * FROM $tbl_name LIMIT $start, $limit";
    }
}
