在codeigniter中取消一些会话数据

Question

我在会话中保存了一些数据,并在我的网站中保存了某些点,我给用户提供了根据数组键删除会话的某些部分的选项,我得到的数组,

print_r($this->session->userdata('shortlist'); 这给我留下了以下输出,

Array ( [0] => Array ( 
    [id] => 40 
    [name] => Namey Name 
    [location] => location is a place 
    [talent] => voice over 
    [image] => ./media/uploads/headshots/width_60_249613_10150280293315435_717615434_9570480_8341358_n.jpg ) );

如何从我的候选名单会话中删除此内容？我尝试过以下操作,但无济于事,

unset($this->session->userdata('shortlist')[0]);

Answer 1

你可以用这个:

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

编辑:评论后:你可以这样做 -

$shortlist = $this->session->userdata('shortlist');
unset($shortlist[0]);
$this->session->set_userdata('shortlist',$shortlist);
