Codeigniter未定义的变量

Question

未定义

现在我想创建更新功能，我出现了未定义变量的问题。我使用相同的方法添加这个工作正常。我是编码的新手，也许有简单的答案，但我找不到。

控制器

$event_title = $this->input->post('title');
            $event_description = $this->input->post('description');
            $event_phone = $this->input->post('phone');
            $event_email = $this->input->post('email');
            $event_keywords = $this->input->post('keywords');
            $date_start = $this->input->post('date_start');
            $time_start = $this->input->post('time_start');
            $date_end = $this->input->post('date_end');
            $time_end = $this->input->post('time_end');

            $start = date_format(date_create( $date_start.' '.$time_start),"Y-m-d H:i:s");
            $end = date_format(date_create( $date_end.' '.$time_end),"Y-m-d H:i:s");




            if(!empty($_FILES['picture']['name']))
            {
                $data['picture'] = $this->validator->upload_image('./uploads/events/main','picture'); 
                $this->validator->resize_image($data['picture'],'./uploads/events/main','event_main_size');
            }

            $event_basic = [
                                'title'         => $event_title, 
                                'main_photo'    => $picture,
                                'description'   => $event_description,
                                'email'         => $event_email,
                                'phone'         => $event_phone,
                                'keywords'      => $event_keywords,
                                'start'         => $start,
                                'end'           => $end, 
                                'created_at'    => date('c')
                           ];

            $this->events_model->update_event_base($event_basic,$event_id);

模型

public function update_event_base($event_basic,$event_id){
    return  
    $this->db->where('event_id', $event_id)
             ->update('events', $event_basic);
}

错误

严重性：注意

消息：未定义的变量：图片

请检查一下。它可以帮到你。

$picture = $_FILES['picture']['name'];
     $event_basic = [
                                'title'         => $event_title, 
                                'main_photo'    => $picture,
                                'description'   => $event_description,
                                'email'         => $event_email,
                                'phone'         => $event_phone,
                                'keywords'      => $event_keywords,
                                'start'         => $start,
                                'end'           => $end, 
                                'created_at'    => date('c')
                           ];
