A quick guide to Magento 2 basic customisation – Part 1

1. Programmatically Get URLs in Magento

Step 1:

The initial step is to Create scripts/magentoUrl.php file.
Now place this file in the Magento root directory and just enter the code displayed below.

<?php

require dirname(__FILE__) . '/../app/bootstrap.php';
$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $_SERVER);

$objectManager = $bootstrap->getObjectManager();

$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');

$storeManager = $objectManager->get('Magento\Store\Model\StoreManagerInterface'); 

// For Site Base url
$baseUrl= $storeManager->getStore()->getBaseUrl();

// For Link url:
$linkUrl = $storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_LINK);

//For Media url:
$mediaUrl = $storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);

//For Static Folder url:
$staticUrl = $storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_STATIC);

echo “Site URL: ”.$baseUrl.”<br>”;
echo “Link url: ”.$linkUrl.”<br>”;
echo “Media URL: ”.$mediaUrl.”<br>”;
echo “Static Folder URL: ”.$staticUrl.”<br>”;

?>

2. Programmatically Get Category, Products and Customer data in Magento 2

With Magento 2 you can organise and administer your business data. Moreover its scalability feature allows you to make changes effortlessly.

Follow these simple steps given below to get data related to category, products and customers.

Step 1: First Create the scripts/abstract.php file in magento root directory. Place the following code in the file.

<?php

use \Magento\Framework\AppInterface as AppInterface;
use \Magento\Framework\App\Http as Http;

use Magento\Framework\ObjectManager\ConfigLoaderInterface;
use Magento\Framework\App\Request\Http as RequestHttp;
use Magento\Framework\App\Response\Http as ResponseHttp;
use Magento\Framework\Event;
use Magento\Framework\Filesystem;
use Magento\Framework\App\AreaList as AreaList;
use Magento\Framework\App\State as State;

abstract class AbstractApp implements AppInterface
{
    public function __construct(
        \Magento\Framework\ObjectManagerInterface $objectManager,
        Event\Manager $eventManager,
        AreaList $areaList,
        RequestHttp $request,
        ResponseHttp $response,
        ConfigLoaderInterface $configLoader,
        State $state,
        Filesystem $filesystem,
        \Magento\Framework\Registry $registry
    ) {
        $this->_objectManager = $objectManager;
        $this->_eventManager = $eventManager;
        $this->_areaList = $areaList;
        $this->_request = $request;
        $this->_response = $response;
        $this->_configLoader = $configLoader;
        $this->_state = $state;
        $this->_filesystem = $filesystem;
        $this->registry = $registry;
    }

    public function launch()
    {
        $this->run();
        return $this->_response;
    }

    abstract public function run();

    public function catchException(\Magento\Framework\App\Bootstrap $bootstrap, \Exception $exception)
    {
        return false;
    }
}
?>

Step 2: To avail the category Data

Follow these subsequent steps

Step 2.1: Create scripts/categoryData.php file in magento root directory and place the code below to get category data.

<?php
require dirname(__FILE__) . '/../app/bootstrap.php';
$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $_SERVER);
require dirname(__FILE__) . '/abstract.php';

class CategoriesDataApp extends AbstractApp
{
    public function run()
    {
        $this->_objectManager->get('Magento\Framework\Registry')
            ->register('isSecureArea', true);

        $category = $this->_objectManager->create('\Magento\Catalog\Helper\Category');
        $_categories = $category->getStoreCategories();
        foreach($_categories as $cat){
            $_category = $this->_objectManager->create('\Magento\Catalog\Model\Category');
            $_category = $_category->load($cat->getId());
            $_subcategories = $_category->getChildrenCategories();
            if (count($_subcategories) > 0){
                echo $_category->getId().'=>'.$_category->getName().'
';      
                foreach($_subcategories as $_subcategory){
                     echo "sub category: ".$_subcategory->getId().'=>'.$_subcategory->getName().'
';
                }
            }
        }

        /* for load Specific category uncomment below code */

        //$_category = $this->_objectManager->create('\Magento\Catalog\Model\Category');
        //$_category = $_category->load(4); // your category Id
        //echo '

';print_r($category->getData()); // for get category data
        //$category->delete(); // for delete category
    }
}

/** @var \Magento\Framework\App\Http $app */
$app = $bootstrap->createApplication('CategoriesDataApp');
$bootstrap->run($app);
?>

Step 2.2: Run the command http://www.yourdomian.com/scripts/categoryData.php in your browser. This will provide you all the data related to category right on your screen.
