如何存储帖子变量值 [英] How to store post variables value

问题描述

我有一个包含搜索页面的索引页面，提交后，它通过操作和方法发布将值传递给find.php.代码在下面

I got a Index page on which search page is included, and when I submit it, it passes values to find.php through action and method post. The code is below

if($_POST['searchsubmit']=="Search"){
$cat=$_POST['searchcategory'];
$area=$_POST['searcharea'];
$term=$_POST['searchbox'];
}

上面的代码是写在find.php上的，现在，当我尝试通过基本分页方法实现分页时，要在何处进行适当的搜索查询条件

The above code is written on find.php, Now when I try to implement paging through basic paging method with where conditions to make appropiate search query

$where="where approved='yes'";
        if($term!=""){
            $where.=" and name like '%$term%'";
        }
        if($cat!=""){
            $where.=" and category like '%$cat%'";
        }
        if($area!=""){
            $where.=" and area like '%$area%'";
        }
        $start=0;
        $end=5;
        if($_GET['page']!="")
        {
            $start=$_GET['page']*$end;
        }

其中$ start是我的初始限制，而$ end是我的记录数.对于分页的第一页，我将第一页的变量页面传递为0

Where $start is my initial limit, and $end is my number of records. For the first page of paging, I pass a variable page with 0 for first page

<a href="find.php?page=<?php echo 0;?>">First</a>

现在我的搜索查询变为

$que="select * from shops ".$where." ORDER BY likes DESC  limit $start,$end";

当我单击第一个"时，我的新链接将变为"/find.php?page=0" 而且我从索引页搜索栏中获得的帖子值也丢失了.

As soon as I click on "first", My new link become "/find.php?page=0" and the post values which I recivied from index page search bar are lost.

有什么方法可以保留这些值吗?我还是通过GET通过url再次发送它们的两种方法，或者另一种方法是将它们存储在会话中. 有没有第三种方法?

Is there any way to retain those values ?The two methods which I though are sending them again through url with GET, or the other way is to store them in session. Is there any third method available ?

推荐答案

马克绝对正确.不要按原样使用代码.

Marc is absolutely right. Do not use the code as it is.

作为解决您问题的另一种方法-

As an alternate solution to your problem -

• 您的页面index.php(搜索表单)提交给自己
• 在搜索查询中将其作为poststring组合成index.php
• 使用组合的查询字符串重定向到find.php
• 所有搜索信息将始终位于查询字符串中.
• 愉快地使用分页.
