####################################### Sample Data install after magento2 install ################

php bin/magento sampledata:deploy


####################################### Install magento with command line ######################
php bin/magento setup:install --base-url="http://127.0.0.1/mage227/" --db-host="localhost" --db-name="mage227" --db-user="root" --db-password="" --admin-firstname="zaheer" --admin-lastname="badi" --admin-email="[email protected]" --admin-user="admin" --admin-password="kgn@123" --language="en_GB" --currency="GBP" --timezone="Europe/London" --use-rewrites="1" --backend-frontname="admin"

###################### Get price inc and excl price ##############

$excPrice = $childProduct->getPriceInfo()->getPrice('final_price')->getAmount()->getBaseAmount();
$inclPrice = $childProduct->getPriceInfo()->getPrice('final_price')->getAmount()->getValue();

#############################################################################

########################## Check customer is logged in even if FPC is enable ##############
use: Magento\Framework\App\Http\Context::getValue(Magento\Customer\Model\Context::CONTEXT_AUTH)
to see if the current user is logged in. This should work even when you have FPC enabled.

############################################################################################

#################### Use block in phtml using DI #########################

You can create a new class (or Service Contract) and add it to the $data-array using di.xml:

<type name="Vendor\Module\Block\Example">
    <arguments>
        <argument name="data" xsi:type="array">
            <item name="my-custom-stuff" xsi:type="object">Vendor\AnotherModule\Block\Example</item>
        </argument>
    </arguments>
</type>

The above code adds a new instance of Vendor\AnotherModule\Block\Example to your
(overwritten) template file. In that file you can access your block class like so:

/** @var \Vendor\Module\Block\Example $block */
/** @var \Vendor\AnotherModule\Block\Example $myCustomStuff */
$myCustomStuff = $block->getData(‘my-custom-stuff’);

############################ Set collection to Magento Listing ###################################
<?php echo $this->getLayout()->createBlock("Magento\Catalog\Block\Product\ListProduct")->setCollection($categoryProducts)->setTemplate("Magento_Catalog::product/homelist.phtml")->toHtml();?>

##################################### Check is customer logged in ######################################
$om = \Magento\Framework\App\ObjectManager::getInstance();
/** @var \Magento\Framework\App\Http\Context $context */
$context = $om->get('Magento\Framework\App\Http\Context');
/** @var bool $isLoggedIn */
$isLoggedIn = $context->getValue(\Magento\Customer\Model\Context::CONTEXT_AUTH);

     if($isLoggedIn == 1){
     //Customer is Logged In
     }



##################################### Ajax form submit #########################
<script type="text/javascript">
require([
    "jquery",
    "mage/mage"

    $(document).ready(function() {
        $('#custom-contact-form').mage(
