How to make a simple website for internal use with custom php and js scripts?

Question

CMS

I want to make a website for internal use in a non-profit organization. It should have something like a simple CRUD to the database, and a couple of custom scripts that I will write.
The question is what can be used in order not to write from scratch such things as user authorization, sessions, design, and other things that any site will need. I looked first towards Drupal, then towards WordPress, but here and there, in order to use custom scripts in php and js, you need to write your own modules. Studying the structure of modules for such a simple project seems like an overkill to me.
Is there some simpler system that would give the standard basic functionality for the site, but not restrict me from using the scripts I wrote?
Thanks in advance.

Answer 1

If design is not fundamental, then why not love wiki engines? Among them are a lot of those who support scripts, I use XWiki, written in Java, LGPL distribution license, functionality includes a blog, API tools, comments, LDAP authentication, export pages to PDF. It is also possible to program scripts (Velocity, Groovy, Python, Ruby and PHP) and support the syntax of popular Wiki engines (Confluence, JSPWiki, Creole, MediaWiki, and TWiki)

Check out the Yii 2 framework. It has a code generator - Gii, which generates not only controllers and models, but also views for CRUD actions.

Try some kind of php framework, there are quite a lot of them, it is not necessary to take a large one, you can look at microframeworks like cakephp
