The scenario is I have multiple if-conditions to create product programmatically or load at controller action. I need a single variable who's value should be updating through different functions.

I have tried custom php ways but are not working. How can I achieve this?

Edit

Here is my class, I want to create product one(first) time and after that each time same product should gets load so that it could be added to cart programmatically. I am loading product using SKU. To read code please focus on $sku variable which I want to make global or static.

class Index extends MagentoFrameworkAppActionAction

protected $resultPageFactory;
protected $session;
protected $sku;
private $productRepository;
public function __construct(
 FormKey $formKey,
 Cart $cart,
 Product $product,
 MagentoFrameworkAppActionContext $context,
 MagentoCustomerModelSession $customerSession,
 MagentoCatalogApiProductRepositoryInterface $productRepository,
 PageFactory $resultPageFactory
)

 $this->session = $customerSession;
 $this->formKey = $formKey;
 $this->sku = $sku;
 $this->cart = $cart;
 $this->productRepository = $productRepository;
 $this->product = $product; 
 parent::__construct($context);
 $this->resultPageFactory = $resultPageFactory;

public function execute()

 if (!$this->session->isLoggedIn())
 
 $resultRedirect = $this->resultRedirectFactory->create();
 $resultRedirect->setPath('customer/account/login');
 return $resultRedirect;
 
 else
 
 $resultPage = $this->resultPageFactory->create();
 $resultPage->getConfig()->getTitle()->set(__('My Wallet'));


 $vat_exempt_name = $this->getRequest()->getPost('vat_exempt_name');
 //...........Load Product...............//
 $product= $this->loadMyProduct();
 $ID = $product->getId();

 //.............. For Add to Cart .........//
 $productId =$ID;
 $params = array(
 'form_key' => $this->formKey->getFormKey(),
 'product' => $productId, 
 'qty' =>1
 );
 $product = $this->product->load($productId); 
 $this->cart->addProduct($product, $params);
 $this->cart->save();
 return $resultPage;
 
 
 public function loadMyProduct()
 
 if (empty($this->sku))
 $this->createProduct();
 
 else
 return $this->productRepository->get($this->sku);
 
 
 public function createProduct()
 $posted = $this->getRequest()->getParam('vat_exempt_name');
 $objectManager = MagentoFrameworkAppObjectManager::getInstance(); // instance of object manager
 $product = $objectManager->create('MagentoCatalogModelProduct');
 $product->setSku('my-sku44'); // I need this SKU to be set for global variable $sku
 $product->setName('Wallet Amount'); // Name of Product
 $product->setAttributeSetId(4); // Attribute set id
 $product->setStatus(1); // Status on product enabled/ disabled 1/0
 $product->setWebsiteIds(array(1));
 $product->setWeight(10); // weight of product
 $product->setVisibility(4); // visibilty of product (catalog / search / catalog, search / Not visible individually)
 $product->setTaxClassId(0); // Tax class id
 $product->setTypeId('simple'); // type of product (simple/virtual/downloadable/configurable)
 $product->setPrice(199); // price of product
 $product->setStockData(
 array(
 'use_config_manage_stock' => 0,
 'manage_stock' => 1,
 'is_in_stock' => 1,
 'qty' => 99999
 )
 );
 $product = $product->save();
 $ID = $product->getId();
 //global $sku;
 $this->sku = $product->getSku(); // here global variable $sku should update
 

Thanks.

I think I'm more going to answer a "php question" than a "magento question" here.

I would have use

$this->sku

and declare it with the others (protected $resultPageFactory;protected $session;private $productRepository;)

Its value will be updated in the object rather than in the method.

I Hope I'm clear enough ;)

If not, there is the documentation.

I solved problem using core session to store value and access globally, here is example to understand concept:

use MagentoFrameworkSessionSessionManagerInterface as CoreSession;

class MyClass


protected $_coreSession;

public function __construct(
 ...
 CoreSession $coreSession
 ...
) 
 $this->_coreSession = $coreSession;


public function setValue()
 $this->_coreSession->start();
 $this->_coreSession->setMyVariable('My variable value');

Get your variable value anywhere by core session as:

public function getValue()
 $this->_coreSession->start();
 return $this->_coreSession->getMyVariable();

We can also unset session variable by

public function unsetValue()
 $this->_coreSession->start();
 return $this->_coreSession->unsMyVariable();
