DX Template Manager

Create page templates like the ones in your theme folder but through a «DX Templates» menu in your Admin dashboard. Paste HTML, JS and PHP code which you could assign to your posts, pages or custom post types via a meta box dropdown. Create page templates and apply them to be evaluated.

Note: eval() function is used. However, it is available only for admin users to submit code and normally admin users could do a lot harm or upload external harmful plugins as well.
