I am building a plugin for the first time and I have setup my rewrite rules to call a PHP file I have located in my plugin folder and this is working but all I have it output just now is "test"
I wanted to ask, is there is a way of pulling in the existing theme and using this as the basis for the page, then I can have my plugin just output the page content area so to speak.
My plugin is quite big in terms of the amount of data it handles so I would like to be able to use a menu link to the aforementioned file and this file can then output all the sub pages of content but still using the default theme (theme I have made) and fill the content area only is this possible and if so is there anything to explain this already available because I couldn't see it.
Any help with this would be much appreciated.
Edit: I have tried including a file from my current theme but this will give me a 500 error so I assume its not as simple as this.
