3 | * Unified backend for ImageManager |
---|
4 | * |
---|
5 | * Image Manager was originally developed by: |
---|
6 | * Xiang Wei Zhuo, email: xiangweizhuo(at)hotmail.com Wei Shou. |
---|
7 | * |
---|
8 | * Unified backend sponsored by DTLink Software, http://www.dtlink.com |
---|
9 | * Implementation by Yermo Lamers, http://www.formvista.com |
---|

---|
15 | * DESCRIPTION: |
---|
16 | * |
---|
17 | * Instead of using separate URL's for each function, ImageManager now |
---|
18 | * routes all requests to the server through this single, replaceable, |
---|
19 | * entry point. backend.php expects at least two URL variable parameters: |
---|
20 | * |
---|
21 | * __plugin=ImageManager for future expansion; identify the plugin being requested. |
---|
22 | * __function=thumbs|images|editorFrame|editor|manager function being called. |
---|
23 | * |
---|
24 | * Having a single entry point that strictly adheres to a defined interface will |
---|
25 | * make the backend code much easier to maintain and expand. It will make it easier |
---|
26 | * on integrators, not to mention it'll make it easier to have separate |
---|
27 | * implementations of the backend in different languages (Perl, Python, ASP, etc.) |
---|
28 | * |
