Get system config values in magento 2

How to get data from Magento 2 System Configuration ? Here's how to.

We need to call the default method available.

Just Use \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
In your constructor argument and create an Object $this->scopeConfig = $scopeConfig;

Now to Get the configuration value just use
$this->_scopeConfig->getValue('dev/debug/template_hints', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);

First argument is the value which we need from system configuration and the Second argument is the Store scope.


public function __construct(
\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
) {
$this->_scopeConfig = $scopeConfig;

public function helloWorld(){

   $showTemplateHint =  $this->_scopeConfig->getValue('dev/debug/template_hints', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);

Logging in magento 2 including FirePHP

Magento 2 uses Monolog library to log messages. More information about the monolog is here

You can find the Library package in the following location in Magento 2

Log files will be created inside var/log folder.

To add logging to your class we need to add an instance of the monolog class. As magento 2 uses Dependency Injection(DI)  we need to pass the instance in the constructor of your class.

Just for testing, we are going to add this in one of the magento's default class. Go to app/code/Magento/Cms/Block/Page.php

And add the below lines After Protected $pageConfig

* @var \Psr\Log\LoggerInterface
protected $_logger;

And add this line \Psr\Log\LoggerInterface $logger,  as the parameter of the __construct() 

Now we need to create an object. so add these line inside the function

$this->_logger = $logger;
$this->_logger->addDebug('some text or variable');

So Finally our Constructor function will look like this.

public function __construct(
        \Magento\Framework\View\Element\Context $context,
        \Magento\Cms\Model\Page $page,
        \Magento\Cms\Model\Template\FilterProvider $filterProvider,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Cms\Model\PageFactory $pageFactory,
        \Magento\Framework\View\Page\Config $pageConfig,
        \Psr\Log\LoggerInterface $logger,
        array $data = []
    ) {
        parent::__construct($context, $data);
        // used singleton (instead factory) because there exist dependencies on \Magento\Cms\Helper\Page
        $this->_page = $page;
        $this->_filterProvider = $filterProvider;
        $this->_storeManager = $storeManager;
        $this->_pageFactory = $pageFactory;
        $this->pageConfig = $pageConfig;
        $this->_logger = $logger;
        $this->_logger->addDebug('some text or variable');


Detailed Article here

Monolog has inbuilt FirePHP logging library. FirePHP is used to send log messages to the FireBug Console. More information here. Install FirePHP Firefox / Chrome addon to use this.

Now to Use FirePHP in Magento 2 just use this line
$this->_logger->pushHandler(new \Monolog\Handler\FirePHPHandler());
$this->_logger->addDebug('some text here');

You can see the message available on the Firebug Console panel, instead of creating a log file.
