我正在使用对 codeigniter 中的页面进行分页的搜索功能。因此，我将搜索词保存在会话中，因此当您切换页面时，该词仍然可用。不过，我有一个小问题，它会保存您输入的所有内容。

我知道我需要使用这个清除会话

$this->session->unset_userdata('searchChal');

但我只是不确定把它放在哪里。我尝试在函数的开头和结尾放置，但它清除会话太快，单击下一页时会话不再存在。

当用户输入另一个值时，有什么方法可以清除会话？还是我只是错过了什么？

这是我的功能

public function searchChallenges(){
//This function allows you to search through all the challenges
    $config["base_url"] = base_url()."index.php/story/searchChallenges";
    $config["total_rows"] = $this->data_model->searchChal_count();
    $config["per_page"] = 1;
    $config["uri_segment"] = 3;
    $choice = $config["total_rows"] / $config["per_page"];
    $config["num_links"] = round($choice);
    $this->pagination->initialize($config);
    $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
    $searchTerm = $this->input->post("searchC", TRUE);

    if($searchTerm) {
        $searchChal= $this->input->post("searchC", TRUE);
         $this->session->set_userdata('searchChal', $searchChal);

     }elseif($this->session->userdata('searchChal')){
         $this->search = $this->session->userdata('searchChal');

     }else{
        $searchTerm ="";
     }

        if (empty($this->user)) {
            $this->load->view('header_view', array(
                'cSearch' =>  $this->session->userdata('searchChal'),
            ));
            $story = $this->story_model->searchChal($config['per_page'], $page);
            if (! isset($story[0]->challenge_id)){
                $this->load->view('noSearchChal_view');
            }else{
                $this->load->view('challenge_view', array(
                    'query' => $this->story_model->searchChal($config['per_page'], $page),
                        'links' => $this->pagination->create_links(),
                        'searchTerm' =>   $this->session->userdata('searchChal'),
                )); 
            }   
            $this->load->view('footer_view');   
        }else{
            $this->load->view('header_view',array(
                'user' => $this->users_model->getUser($this->user->user_id),
                'cSearch' =>  $this->input->post("searchC"),
            ));
            $story = $this->story_model->searchChal($config['per_page'], $page);
            if (! isset($story[0]->challenge_id)){
                $this->load->view('noSearchChal_view');
            }else{
                $this->load->view('challenge_view', array(
                    'query' => $this->story_model->searchChal($config['per_page'], $page),
                    'links' => $this->pagination->create_links(),
                    'admin' => $this->admin_model->adminSearchChal(),
                    'searchTerm' =>  $searchTerm,
                )); 
            }   
            $this->load->view('footer_view');   
        }
}

我将不胜感激一些帮助！

把它放在页脚视图之后： -

$this->session->unset_userdata('searchChal');
