ThinkPHP upload file summary

This article summarizes several methods of uploading files by combining js and php

• Test environment Thinkphp3.2, phpStudy2014 (Apache + php 5.3)
• No matter which method, you must first configure the php upload file size
  Open php.ini and modify the following three items:
  max_execution_time = longest execution time (0 means no limit)
  post_max_size = maximum size allowed
  upload_max_filesize = the maximum size of the uploaded file

Thinkphp uploads files directly

Thinkphp's own upload class, supports multiple file uploads, refer to the documentation
Note: The form tag needs to add enctype="multipart/form-data"

If you want to display the image without refreshing after uploading, you need to upload it with ajax, and then set src according to the returned image address. However, ajax cannot add enctype, so you need other method.

You can use iframe http://blog.csdn.net/hytfly/article/details/6267229
You can also use xhr http://updates.html5rocks.com/2012/04/Processing-XHR2-file-uploads-in-PHP
