Flash variables\hive values null in template

[Yoeri Nijs]

For a new project, I work with Ikkez's Flash plugin. This plugin is great for displaying messages and I am using it with a lot of joy for another project as well. 

Now, for a new project, I am working with Flash again, but the plugin does not work. The messages are null after a addMessage() and a direct get request to '/', while this does work for the other project. After some debugging, I am unable to determine what the cause is. Maybe you guys have an idea? I assume it has something to do with my autoload in globals.ini, but I am not sure (all other views do work, though). 

The setup is as follows:

- app
  - config
    - globals.ini
    - message.ini
    - ...
  - controllers
    - ...
  - models
    - ...
  - core
    - component
      - message
        - Message (is just a wrapper for Flash)
        - ...
      - ...
  - views
    - inc
      - components
        - message.htm
        - ...
      - ...
    layout.htm

Globals.ini

[globals]

; Load directly

AUTOLOAD = ../app/

UI = ../app/views/

Message.ini (contains just some styling and some default labels)

[message]

                break;

The message.htm component (uses Tailwind). I should use a switch here ;)

In layout.htm, I display the components view like so. 

<!-- Messages -->

<include href="inc/components/message.htm" />

When I change to content of message.htm to 'foo' and nothing else, 'foo' is displayed. This tells me that Flash might not be reachable by the template, hence my autoload assumption.

Are you sure to use the template engine to render the template? (not view or preview?!)

The SESSION is also working correctly?

If Flash is not be available, I guess it would raise an error 500 instead of just doing nothing.

I am using Template for GET requests. This works:

// GET REQUEST

function getFunction() {
  Message::infoCustom('foo');
  $this->render()
}


protected function render(): void {
     $template = new Template();
     echo $template->render('layout.htm');
 }

However, this does not work (i.e.: I do not see any message). I am just initializing this with the router:

// POST REQUEST

function postFunction() {
  Message::infoCustom('foo');
  $this->f3->reroute('/');
}

// ROUTE '/'

function getRequest() {

  $this->render();

}

Is my implementation wrong?

Well, it turns out that setting a SQL session prior to displaying any messages is responsible for this behaviour.

So executing new Session() before all of this breaks everything. I do not understand it atm, so I will debug it later.
