        $result = $this->addcategory->addcategory($add_cat); //Save the data
        if($result > 0){ //Check last inserted id
            if(!empty($_FILES['HM_cat_image']['name'])){ //check file upload or not
                $time = time();
                $upImage = uploadImage($_FILES['HM_cat_image'],$time); //Helper function to upload image in folder
                if($upImage == 1){ // if file upload then return 1
                    $catImage = $time . '_' . $_FILES['HM_cat_image']['name'];
                    $catImageData = array('category_id' => $result,'image' => $catImage);
                    $imgRes = $this->addcategory->addCategoryImage($catImageData); // Save image in database
                    if($imgRes > 0){
                        $this->session->set_flashdata('message', 'Information Has been Successfully Saved');
                    }else{
                        $this->session->set_flashdata('message', 'Information Has been Successfully Saved But Error In Image Saving.');
                    }
                }else{

Answer 1

检查以下几点，希望这会有所帮助。

将您的CI encryption_key设置为＆＃39; application / config.php＆＃39;使用会话。
加载会话库
检查您的表单是否已接受＆＃39; multipart＆＃39;。

Answer 2

确保您的会话已创建，请在您的登录控制器上添加此代码

$this->output->enable_profiler(true);

在codeigniter profiler输出的会话部分中搜索并找到您想要的会话。

或者您可以在数据库中保存会话，使用

$config['sess_use_database'] = TRUE;

并设置

会话在codeigniter中断了
