Question

我遇到了一个问题，我希望将数组中的ID存储在一个会话中，如数组（[＆＃39; docid＆＃39;] =＆gt; 1，[＆＃39; docid＆＃ 39] =→2，[＆＃39;文档ID＆＃39] =→3，[＆＃39;文档ID＆＃39] =→4，[＆＃39;文档ID＆＃39;] =＆GT ; 5，[＆＃39; docid＆＃39;] =＆gt; 6，[＆＃39; docid＆＃39;] =＆gt; 7）就像这样，当我点击时，我希望单个会话中的ID在链接上，任何帮助将不胜感激。谢谢

这是我的代码： -

public function addtoshortlist()
{

     $shortlist=array('docid'=>$_GET['id']);
    $this->session->set_userdata('shortlist',$shortlist);
    print_r($this->session->userdata('shortlist'));
    //$this->session->userdata('shortlist')['docid'];

    redirect($this->agent->referrer());
}

试试这个

public function addtoshortlist()
{
     $shortlist=array('docid' => array($_GET['id']));
     if(!$this->session->userdata('shortlist')['docid'])
     {
          $this->session->set_userdata('shortlist',$shortlist);
     }else{
          $session = $this->session->userdata('shortlist')['docid'];
          if(!in_array($_GET['id'],$session))
          $session[]=$_GET['id'];
          $this->session->set_userdata('shortlist',array('docid'=>$session));
     }
     print_r($this->session->userdata('shortlist'));

    redirect($this->agent->referrer());
}

在codeigniter中存储数组中的值
