加载图像预览Codeigniter

Question

我正在开发一个模块(在Codeigniter中)，用户可以在其中上传图像。他有权查看图像的预览，了解图像将如何显示。我想用ajax来做这件事。

      1. Is is necessary to upload the image (ie save image in our database , get the url where it is stored and Load the image) to load the preview of the image.

      2. Is there any other way through which I can display the preview without storing the image in our database. (Getting the url from the client side  and displaying it.. How to do this ? )

Answer 1

将镜像上传到您的资源文件夹中，并在表中插入镜像的路径。当你想预览图片时，将链接放入图片标签( <img src="path of the image from table" /> )。
