Good front end to wp programming

I used data access to develop mysql queries to manage my project data. The query manager in data access does not have short codes so I had to manually go into the queries and run them when I wanted to change my data.
With code manager I was able to create php code which ran those queries from wp pages. I simply used the code manager shortcodes for those php programs that ran the queries and inserted them into pages.
I used session variables to pass data from program to program and even created drop-down menus to allow the user to select the data to pass to those session variables.
Again, no hesitation in recommending this plugin to anyone willing to experiment and learn!
