图片上传无法在codeignitor中使用

Question

我创建图像上传代码.首先创建目录,然后将图像上传到它.

在表单中我上传了3张图片.

我的代码是:

$dir_path = 'assets/images/product_images/'.$model;
mkdir($dir_path, 0777);

$i = 1 ;

    foreach ($image as $new_image)
        {
            $dir_path_up = 'assets/images/product_images/'.$model."/";
            $filename = $_FILES["$new_image"]["name"];
            $image_name  = $dir_path_up .$filename . $i. ".jpg";
                echo $image_name;

                $i++;
        }
        die();

回声的结果

assets/images/product_images/255_2555/1.jpg
assets/images/product_images/255_2555/2.jpg
assets/images/product_images/255_2555/3.jpg

但是这些图像并没有进入目录.我回应了我创建的图像名称.它的alredy重新命名.那么为什么图像没有上传到目录中.

这有什么不对？

从这里阅读CI图像上传手册.

在codignator中我们使用上传库来上传图片.

你根据你的要求传递你的参数

           $config['upload_path'] = 'assets/images/product_images/'.$model."/";
            $config['allowed_types'] = 'gif|jpg|png';
            $config['max_size'] = '100';
            $config['max_width']  = '1024';
            $config['max_height']  = '768';

            $this->load->library('upload', $config);

            if ( ! $this->upload->do_upload())
            {
                $error = array('error' => $this->upload->display_errors());

                $this->load->view('Your View', $error);
            }
            else
            {
                $data = array('upload_data' => $this->upload->data());

                $this->load->view('Your View', $data);
                }
