Example for beginners on how to call vars from $this when looking at values from settings.php

[Guyverix]

I should clarify, the "$test = $this->get(PDO::class);" is one of the attempts I have made in my Action however since I already see the data inside the object, I moved on to trying to pull it out via the "$this->db->driver" and failing..

Sorry for any confusion.

You need to add PDO::class as a dependency in the constructor of your actions, PHP-DI will inject the dependency in there for you.

<?php
declare(strict_types=1);

namespace App\Application\Actions\User;

use App\Application\Actions\Action;
use App\Domain\User\UserRepository;
use Psr\Log\LoggerInterface;

abstract class MyAction extends Action
{
    protected PDO $db;

    public function __construct(LoggerInterface $logger, PDO $db)
    {
        parent::__construct($logger);
        $this->db = $db;
    }

   protected function action(): Response
   {
       $test = $this->db->doSomething();
   }
}

Still getting errs that it cannot seem to find the PDO that are defined in the settings.php and dependencies.php files..

"Error while injecting dependencies into App\\Application\\Actions\\Mapping\\ViewAllMappingAction: No entry or class found for 'App\\Application\\Actions\\Mapping\\PDO'"

This is literally what I have defined in the depnedencies.php. I know full well I am the one causing the problem not understanding the framework well enough yet. Just one heck of a road-block that I cannot seem to get past.

<?php
declare(strict_types=1);

use App\Application\Settings\SettingsInterface;
use App\Application\Settings\Settings;
use DI\ContainerBuilder;
use Monolog\Handler\StreamHandler;
use Monolog\Logger;
use Monolog\Processor\UidProcessor;
use Psr\Container\ContainerInterface;
use Psr\Log\LoggerInterface;

return function (ContainerBuilder $containerBuilder) {
    $containerBuilder->addDefinitions([
        LoggerInterface::class => function (ContainerInterface $c) {
            $settings = $c->get(SettingsInterface::class);

            $loggerSettings = $settings->get('logger');
            $logger = new Logger($loggerSettings['name']);

            $processor = new UidProcessor();
            $logger->pushProcessor($processor);

            $handler = new StreamHandler($loggerSettings['path'], $loggerSettings['level']);
            $logger->pushHandler($handler);

            return $logger;
        },
        PDO::class => function (ContainerInterface $c) {
            $settings = $c->get(SettingsInterface::class);
            $dbSettings = $settings->get('db');
            $host = $dbSettings['host'];
            $dbname = $dbSettings['database'];
            $username = $dbSettings['username'];
            $password = $dbSettings['password'];
            $charset = $dbSettings['charset'];
            $flags = $dbSettings['flags'];
            $dsn = "mysql:host=$host;dbname=$dbname;charset=$charset";
            return new PDO($dsn, $username, $password);
        },
    ]);
};

Still getting errs that it cannot seem to find the PDO that are defined in the settings.php and dependencies.php files..

"Error while injecting dependencies into App\\Application\\Actions\\Mapping\\ViewAllMappingAction: No entry or class found for 'App\\Application\\Actions\\Mapping\\PDO'"

Add a backslash to the PDO class reference:

abstract class MyAction extends Action
{
    protected \PDO $db;

[Guyverix]

No change. Still says it cannot find the class. In this framework, is it more reasonable to create a separate PDO file and call it with use instead of trying to make dependencies.php work?

<?php
declare(strict_types=1);

namespace App\Application\Actions\User;

use App\Application\Actions\Action;
use App\Domain\User\UserRepository;
use Psr\Log\LoggerInterface;

abstract class MyAction extends Action
{
    protected \PDO $db;

    public function __construct(LoggerInterface $logger, \PDO $db)
    {
        parent::__construct($logger);
        $this->db = $db;
    }

   protected function action(): Response
   {
       $test = $this->db->doSomething();
   }
}

You`ve declared the \App\Application\Actions\Mapping. So PDO without namespace will be \App\Application\Actions\Mapping\PDO. You need \PDO class for $db variable.

Thank you for the example. This is making more sense to me now.
