使用codeigniter上传原始图像后如何裁剪和接收两张图像

Question

我创建了一个库，它只上传 1 张图片，并根据路径、宽度和高度对其进行裁剪。但我不知道如何让它裁剪尽可能多的图像并返回它创建的所有文件名的数组。这是我的图书馆，如果有好的方法，请告诉我。谢谢

        //if upload do something
        if($CI->upload->do_upload())
        {
            $image_data = $CI->upload->data();

            $config2 = array(
                'image_library' => 'gd2',
                'source_image' => $image_data['full_path'],
                'new_image' => $path . '/' . $image_data['file_name'],

                'height' => $height
            );


            $CI->load->library('image_lib', $config2);
            $CI->image_lib->resize();
            return $image_data['file_name'];
        }
        else
        {
            return FALSE;
        }
    }
}

更新：我想通了，这是课程以及如何为任何尝试做某事的人使用它。这个类的作用是上传图片，并让您创建任意大小的原始上传文件。

        $config = array(

        );

        $CI->load->library('image_lib', $config);
        $CI->image_lib->resize();

        $CI->image_lib->clear();
        unset($config);
        return $data['file_name'];
    }
}

用法

$img1 = $this->up_image->upload_image();
$thumb = $this->up_image->resize($img1, 140, 120);

$img2 = $this->up_image->upload_image();
$large = $this->up_image->resize($img2, 420, 360);

将裁剪方法与上传方法分开。

上传后，对上传的文件分别进行两次裁剪。

删除上传的温度。文件。

完成。
