跨域上传类

Question

I finished writing a website and am currently deploying it on a hosting service. This website consists out of 2 separate domains hosted on the same server. (www.domain1.com & www.domain2.com)

Situation

When moving these domains to the hosting service, I figured that 1 script is not working as it was on the local server. This script is a custom upload class in php. This script is located on www.domain1.com but needs to upload the file to www.domain2.com.

My local server is a Xampp server with a simple file structure.

C:/xampp/htdocs

• Domain1/uploadscript.php

• Domain2/destinationfolder/

I am currently using the $_SERVER['DOCUMENT_ROOT'] function to navigate towards the other domain. This method works fine for the local server but not on the hosted version see below.

Main issue

Local server print_r ($_SERVER['DOCUMENT_ROOT']);

= C:/xampp/htdocs

On domain1.com print_r ($_SERVER['DOCUMENT_ROOT']);

= /home/myname/domains/domain1/public_html/

On domain2.com print_r ($_SERVER['DOCUMENT_ROOT']);

= /home/myname/domains/domain2/public_html/

The $_SERVER['DOCUMENT_ROOT'] is not pointing to the "domains" folder but already is pointing to the "public_html" .

The question(s)

How do I navigate towards the "domains" folder on my server? Are there other things necessary for cross domain uploading?

Answer 1

If you want to send some cross domain data, you should set Access-Control-Allow-Origin header.

You can do this in your .htaccess like below:

Header set Access-Control-Allow-Origin "*"

Be sure that you enabled mod_headers in your apache server.

For customizing access you can use something like https://stackoverflow.com/a/10605009/5397119 .
