slim3 | Boilerplate for Slim3 framework | Authentication library

I’m trying to create an authentication system in php with the Slim3 framework along with the Twig template system, and for the database I’m using MySQL with PDO. I’m also trying to implement it using a model view controller design pattern. However I’m having difficulty understanding how to use an MVC structure for a web application. I’ve looked at a plethora of explanations on the web and there doesn’t seem to be a clear cut answer. A lot of people say to to use a php framework such as Laravel, Symfony or CodeIgniter as they apparently employ an MVC like structure. However I would much rather keep things simple and to write the code manually rather than using a framework.

Currently there are two interpretations of MVC that I see. The first one being depicted in this diagram:

The other interpretation I’ve seen is this: (which is taken from this YouTube video)

I have done my research. Questions and answers such as this and this have been helpful. But I’m still not sure how I might structure my own applications, specifically indentifying and understanding the model aspect of MVC. I’ll now explain the register process of my authentication app. So you have an idea how my code is works.

Firstly I have an SQLQueries class that simply puts a series of SQL statements into functions. I then have a SQLWrapper class that has functions that can for example store a new users details inside the database. This class also calls functions from the SQLQueries class. I also have a ValidateSanitize class that has functions that cleans user input as well as checking if user input is valid in the form. These three classes I think are part of the model aspect of MVC but I'm not sure. I see a lot of other tutorials using a ‘User Model class’ but I can’t find the need for one in my application.

My views are simply Twig templates that display html, such as the homepage, register, login etc. I then have controllers. I intend to have multiple controllers that do different things. For now I’ve only implemented the AuthController which is responsible for Registering and Signing a user in.

So the first thing the AuthController does is to display the register form in a function called getRegisterForm. Once the user has submitted the form the postRegisterForm function takes that user input and assigns it to tainted variables.

i have problems on all my slim3/twig projects. i have this error : Class 'Twig_Function' not found.

my projects were working well 1 month ago. see one example : https://github.com/felixleo22/Smash2 (sorry it's in french language)

if someone got this error and got the issue, I will be very happy if more details are needed, i will be there to answer

I'm using Eloquent standalone inside Slim3 framework. I would like to log all DB queries from Eloquent, I see some implementation but what I'm missing is to log the query when it is made and without an explicit code to insert after each model request.

I found this: Laravel Eloquent display query log It works, but the best I could get is a Slim middleware that at the end of all request logs at once al queries.

Probably I need a listener, but how can I use it and how get ALL queries? This is my eloquent bootup inside Slim:

I’m trying to display validation error messages on a registration form. I’m using the Slim 3 framework for the routes and the Twig template system to display the html. Currently I'm trying to display error messages on the registration form if the user fails validation.

Here is the twig code for the registration form, note that {{email_error}}, {{username_error}} and {{password_error}} are Twig delimiters for printing out expressions which in my case is an error message for each input field.

register.html.twig:

Can somebody explain me why when I try to use PDO::PARAM_STR in my code, SLIM3 returns me an error ?

hi Guys im having trouble with get body form value in slim framework 3.

I am trying to implement http DELETE. The app is written with php and slim3 framework. The frontend is angular 2.

If the pattern looks like:$slimApp->delete('/delete', ...) everything is fine.

As soon as I introduce params like: $slimApp->delete('/delete/{id}', ...) I get the following error:

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

I already read the docs https://www.slimframework.com/docs/cookbook/enable-cors.html but however I cannot get it work.

Here is my middleware:

I want to prefix the incoming URL using an htaccess file. For example, the URL might be http://localhost/george_shop.html, I want the htaccess to prefix it like http://localhost/route/george_shop.html

This is my htaccess right now:

I'm new to SLIM3 and followed the tutorial to get some functions in the container that I want to access from anywhere in the code. So here's my index.php file where I initalise everything:
