how to use post method in two functions in codeigniter

我有两个函数使用post方法。它们工作得很好。但问题是我不能同时使用这两种工具。如何解决这个问题?

function search_keyword()
{
    $keyword = $this->input->post('keyword');
    $this->data['result'] = $this->mymodel->search($keyword);
    $this->twig->display('home.html', $this->data);
}
function genarate_csv(){
    $pro_id = $this->input->post('keyword');
    $this->data['re'] = $this->csv->ExportCSV($pro_id);
}

你可以试试这个方法

function search_keyword()
    {
        $keyword = $this->input->post('keyword');
        $this->data['result'] = $this->mymodel->search($keyword);
        $this->data['re'] = $this->genarate_csv($keyword);
        $this->twig->display('home.html', $this->data);
    }
    function genarate_csv($keyword){
        $re = $this->csv->ExportCSV($keyword);
        return $re
    }

try this

function search_keyword()
{
    $keyword = $this->input->post('keyword');
    $this->data['result'] = $this->mymodel->search($keyword);
    $this->data['re'] = $this->csv->ExportCSV($keyword);
    $this->twig->display('home.html', $this->data);
}

你可以在同一个函数中做

buhaaaaa haaaa....我解决了我的问题。我用治疗来解决我的问题。我想这会帮助像我这样的新手。

function __construct()
{
    parent::__construct();
    $this->load->model('mymodel');  
    $this->load->model('csv');  
    session_start();
    $this->load->library('session');
}

public function search_keyword($key = "")
   {
       $keyword    =   $this->input->post('keyword');
       $this->data['result']    =   $this->mymodel->search($keyword);
       $_SESSION[$key] = $keyword;            
       $this->twig->display('home.html', $this->data);
   }
public function download($key = ""){
    //print_r($_SESSION[$key]);
    $keyword = $_SESSION[$key] ;
    //print_r($keyword);
    $this->data = $this->csv->ExportCSV($keyword);
    $this->session->unset_userdata($keyword);
    //$this->twig->display('home.html', $this->data);
}
