This question already has an answer here:
I wonder if I could produce a blank page (not within theme) and write something to it - I need my custom page. I know about WP Ajax, but it's not that simple, cos I wanted to be able to get some data crossdomain (with PHP and regexp) but Im not sure with that.
Simply: I want bypass the theme (and its design) and give a blank page with custom plugin output. (Would be nice to be able to use WP functions)
Is it possible, or I have to use WP Ajax? Thank you
Edit1: I want to add something like post with it's permalink (following permalink structure), but without using theme - just blank page with data created by plugin
I know about including WP into external PHP files. I dont want any external file - it should be working within plugin
