Help Implimenting a modular structure and role based security

Ok, I have a php/mysql web application I have been building for many years. When I started building the app I didn't know anything about php/mysql, so its pretty amateur, some of the newest code is a bit better....

The web app is a CRM package, but it uses multiple databases, so each account will have their own database but use the same front end code.

The problem is that adding customer specific modules, or any sort of module is a little tedious.

I know nothing about implementing a modular structure. I do have a 'sort of' modular structure, however I don't know if it’s a little amateur as there maybe a much better way of modularising a system.

The module structure is simply a set of fields in the database. At the top of each page I query the table and get back a set of variables. Within the page I use the variables to determine whether to display something or not.

i.e. navdiary = 1 (this is if the diary module is active)

then in the code I would do something like:

<?

If($navdiary == 1){

Echo ‘this is the diary’;

}

I have also implemented a very standard security system. A user has level 1-5. Level 5 can do everything, level 1 can't!

Again the problem is flexibility. I want to add a role based system.

Now the design I have in mind is basic, however I want the users to be assigned to a role, but they can have individual preferences to.

This was I can assign 10 people to a role that can view notes, and only one person within those 10 that can view and delete the notes.

Now, I don't expect anyone to actually implement this throughout the app (unless you give me a good price!) however I would like you to implement this on a couple of pages. I can then have a go at using the structure and implementing it site wide.
