flashdata codeigniter with array

Question

我在flashdata codeigniter上的数组有问题发送警报，如果没有框架这个代码工作正确，我将其修改为codeigniter，但它不起作用。

控制器代码：

    function reply(){
    $id = $this->input->post('id');

    $err = array();

    if(!$_POST['msg']) {
        $err[] = 'all the fields must be filled in!';
    }

    else if(!count($err)){
        $data = array(
            'DestinationNumber'=> $this->input->post('hp'),
            'TextDecoded'=> $this->input->post('msg'),
            'i_id'=> $this->input->post('id'));

        $this->inbox_model->reply($data);

        if($data >= 1) {
            $this->session->set_flashdata['msg']['success']='Send Success!';
        }

        else {
            $err[] = 'Send Failed!';
        }

    }

    if(count($err)){
        $this->session->set_flashdata['msg']['err'] = implode('<br />',$err);
    }

    redirect('sms/inbox/read/'.$id);
}

查看代码：

if($this->session->flashdata['msg']['err']){
     echo "<div class='alert alert-danger alert-dismissible'>
           <button type='button' class='close' data-dismiss='alert' aria-hidden='true'>&times;</button>
           ".$this->session->flashdata['msg']['err']."</div>";
           $this->session->unset_flashdata['msg']['err'];
}                    
if($this->session->flashdata['msg']['success']){
     echo "<div class='alert alert-success alert-dismissible'>
           <button type='button' class='close' data-dismiss='alert' aria-hidden='true'>&times;</button>
           ".$this->session->flashdata['msg']['success']."</div>";
           $this->session->unset_flashdata['msg']['success'];
}

谁能帮帮我？

Answer 1

您可以使用简单的方法将数组设置为flashdata会话

$array_msg = array('first'=>'<p>msg 1</p>','second'=>'<p>msg2</p>');

然后将其传递给会话

$this->session->set_flashdata('msg',$array_msg);

然后访问它

$msg = $this->session->flashdata('msg');
echo $msg['first'];

控制器：

$err = array();
if(!$_POST['msg']) {
$err['msg_err'] = '<strong>Oh snap!</strong> all the fields must be filled in';}

查看：

if($this->session->flashdata('err')){
echo "<div class='alert alert-danger alert-dismissible'>
<button type='button' class='close' data-dismiss='alert' aria-hidden='true'>&times;</button>
".$this->session->flashdata('err')['msg_err']."</div>"; }
