In my php script, I'm trying to get the query string ($_SERVER['QUERY_STRING']), append it to another url, and then make a redirect.
If I use the query string without any processing, the new url shows "& amp;" for all the "&'s." Therefore the new url won't work.
I print out the $_SERVER['QUERY_STRING'] and view the page source. It does use "& amp;" for all the "&'s." It doesn't make sense to me and I wonder why. Is it just my server's configuration or PHP's default?
UPDATE: I tested it on MODX CMS using snippet. If running on a regular PHP script, there is no such issue. I guess the problem is with MODX. Any idea?
Just an idea: If you use TinyMCE to edit stuff, it changes all &'s to &'s - that has been driving me crazy for a lot of times. That happens in snippet calls and can be debugged if you either deactivate the rich text editor for a resource or "quick edit" a resource.
Also good practice: put snippet calls into a chunk. You can call that chunk without risking the syntax of the snippet call.
