我如何使用 php 在另一个页面中显示单个记录的详细信息

Question

以下代码仅显示记录列表，当我们单击链接时，我希望它转到另一个页面，该页面假定仅显示所选标题的记录详细信息。目前，它总是显示相同的细节。现在只显示所选标题的记录详细信息的解决方案是什么

<table class="table table-striped table-bordered bootstrap-datatable datatable">// the record list table

Answer 1

将表格标题内容更改为锚标签 例如作为

<a href="?sortby=id">ID</a>

然后在服务器端，将查询处理为

$sort = 'id'; if(isset($_REQUEST['sortby'])&&str_replace(' ','',$_REQUEST['sortby'])!="") $sort = $_REQUEST['sortby']; $queryText= "select * from table_name where order by ".$sort;

确保href传递的值是你sql表中的属性名

此代码使查询按 id 默认排序。如果用户使用另一个标题，它将根据需要切换。

希望这行得通..
