Question

我的控制器中有2个函数，我正在使用第一个函数向第二个函数发送会话。我所说的是：

public function search()
{

    $search_term = $this->input->post('search_term');
    $this->session->set_userdata('search_term', $search_term);

    redirect('search_result/');

}

和第二个功能：

function search_result()
{

    $search_term = $this->session->userdata('search_term');
    $data['search_term'] = $search_term;
    $this->load->view('includes/template', $data);

}

一切都很好，但问题是，我想阻止直接访问search_result()功能。我的意思是，当用户直接调用search_term时，我想取消设置search_result()会话。我该怎么办？！

Answer 1

您可以使用flashdata：http://ellislab.com/codeigniter/user-guide/libraries/sessions.html

CodeIgniter支持“flashdata”或仅可用于下一个服务器请求的会话数据，然后自动清除。这些非常有用，通常用于信息或状态消息

这就是你正在寻找的代码：

public function search()
{

    $search_term = $this->input->post('search_term');
    $this->session->set_flashdata('search_term', $search_term);

    redirect('search_result/');
}

function search_result()
{
    $search_term = $this->session->flashdata('search_term') ? $this->session->flashdata('search_term') : '';
    $data['search_term'] = $search_term;
    $this->load->view('includes/template', $data);
}

Answer 2

有很多方法可以做到。这是一些

如果存在，则附加一个get参数，然后搜索else重定向回来

public function search()
{
    $search_term = $this->input->post('search_term');
    $this->session->set_userdata('search_term', $search_term);
    redirect('search_result?status=1');
}
public function search_result()
{
    $status =   $this->input->get('status');
    if(status == 1){
        $search_term = $this->session->userdata('search_term');
        $data['search_term'] = $search_term;
        $this->load->view('includes/template', $data);  
    }else{
        $this->session->unset_userdata('search_term');
        redirect('search');
    }
}

保护你seach_result功能，不要让用户直接调用它。使用_将为您完成。
Here是您可以阅读的链接。

public function search()
{
    $search_term = $this->input->post('search_term');
    $this->session->set_userdata('search_term', $search_term);
    $this->_search_result($search_term);
}
function _search_result($keyword)
{
    if(strlen($keyword)>0){
        $data['search_term'] = $keyword;
        $this->load->view('includes/template', $data);  
    }else{
        redirect('search');
    }
}

在搜索功能

中

redirect('search_result/'.$this->session->userdata('search_term'));

<_>在search_result函数中

function search_result()
{
    if($this->uri->segment(3))
    {
        $search_term = $this->session->userdata('search_term');
        $data['search_term'] = $search_term;
        $this->load->view('includes/template', $data);
    }
    else
    {
        redirect('search_result/','refresh');
    }
}

希望它会对你有所帮助。如果你遇到任何问题，请告诉我。
