Codeigniter 和 GD 图像处理

发布于 2024-08-15 12:46:44 字数 752 浏览 10 评论 0原文

在 codeigniter 中，我正在创建一个应用程序，允许用户一次性上传多个文件，对此我正在使用这个库， http://www.mitesdesign.com/blog/open-source/multi-upload-jquery-code-igniter

我的问题是是否有已上传的多个图像如何在 $config 中定义源图像，到目前为止我已经这样做了，

                    $gd['image_library'] = 'gd2';
            $gd['source_image'] = '';
            $gd['create_thumb'] = TRUE;
            $gd['maintain_ratio'] = TRUE;
            $gd['width'] = 164;
            $gd['height'] = 103;
            $this->load->library('image_lib', $gd);
            $this->image_lib->resize();

您可以看到 source_image 是空的，因为我不知道如何获取用户上传的所有图像。

任何人都可以提出任何建议吗？

In codeigniter I am creating an application that allows the user to upload multiple files in one go, to this I am using this library, http://www.mitesdesign.com/blog/open-source/multi-upload-jquery-code-igniter

My question is if there are multiple images that have been upload how do I define the source image in the $config, so far I have done this,

                    $gd['image_library'] = 'gd2';
            $gd['source_image'] = '';
            $gd['create_thumb'] = TRUE;
            $gd['maintain_ratio'] = TRUE;
            $gd['width'] = 164;
            $gd['height'] = 103;
            $this->load->library('image_lib', $gd);
            $this->image_lib->resize();

as you can see the source_image is empty as I do not know how to get all the images that the user has upload.

Can anyone suggest anything?

查看本文 ZIP 中提供的 Multi_upload 库，您所要做的就是：

$files = $this->multi_upload->go_upload();

这将返回一个如下所示的多维数组：

                        'name' => $CI->upload->file_name,
                        'file' => $CI->upload->upload_path.$CI->upload->file_name,
                        'size' => $CI->upload->file_size,
                        'ext' => $CI->upload->file_ext,
                        'image_type' => $imageVar->image_type,
                        'height' => $imageVar->height,
                        'width' => $imageVar->width

然后只需进行 foreach 并在调整大小代码中使用这些详细信息。

Looking at the Multi_upload library supplied in the ZIP in this article, all you have to do is this:

$files = $this->multi_upload->go_upload();

That will return a multi-dim array like this:

                        'name' => $CI->upload->file_name,
                        'file' => $CI->upload->upload_path.$CI->upload->file_name,
                        'size' => $CI->upload->file_size,
                        'ext' => $CI->upload->file_ext,
                        'image_type' => $imageVar->image_type,
                        'height' => $imageVar->height,
                        'width' => $imageVar->width

Then just foreach through and use those details in your resizing code.
