我有一个搜索代码的程序。当我进行搜索时，它会显示一个带有搜索结果的页面。该页面将显示一些可以点击的内容。当我单击该内容时，它将向我显示产品的详细信息。在此详细信息页面中，当我在浏览器中单击返回时，它应该返回到搜索结果页面，但我在这里发现文档已过期。当我重新加载文档过期的页面时，它将再次显示搜索结果。我正在使用代码点火器。我尝试了一些我发现的代码，但它仍然无法正常工作。那是我的问题。请帮我。谢谢你。

您已经包含了两次表格。一个表单是使用创建的<?php echo form_open('home_controller/search_bar');?>，另一个是 html 中的静态表单。因此需要删除静态 html 表单，for_open 是可以的。在 form_open 中，您需要指定 get 方法。在这里，我更新了此代码-

<div class="header-bottom">
    <div class="col-xs-1">
        <button class="toggle-button"></button>
    </div>
    <div class="col-xs-11">
    <?php echo form_open('home_controller/search_bar',array('method' => 'get'));?>
    <div class="search">

        <input type="text" id= "input-keyword" name="input-keyword" placeholder="Search ..." value="<?php echo set_value('input-keyword')?>" >
        <input type="submit" value="">  
    </div>
   <?php echo form_close(); ?> 
    </div>
<div class="clearfix"> </div>

在 search_bar 函数中的控制器现在使用 get 方法获取表单值，而不是像 as

$keyWordRestoran_ip = $this->input->get('input-keyword');
