Magento – How to set data from controller to .phtml file in magento

custommagento-2.1module

I have created a custom module and there are some drop downs in it. I have done all the things in .phtml file as pure php.

How can I change that to correct way code in my .phtml file:

<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$resource = $objectManager->get('Magento\Framework\App\ResourceConnection');
$connection = $resource->getConnection();

$tableColor = $resource->getTableName('color_price');

$sql = "SELECT * FROM " . $tableColor;
$color = $connection->fetchAll($sql);
?>

drop down like below its in .phtml file too:

<p><br>Frame Color</p>
<select id="color">
<?php
foreach($color as $c){ ?>
    <option value="<?php print_r($c['price_component']);?>"><?php print_r($c['color']);?></option>
<?php
}
?>
</select>

<b><p id="framecolor"></p></b>

below code is my layout.xml file

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd" 
layout="1column">
    <body>
        <referenceContainer name="content">
            <block class="Test2\Helloworld\Block\Helloworld" 
            name="helloworld" template="helloworld.phtml" />
        </referenceContainer>
    </body>
</page>

what is the correct way of doing this. now all the things in .phtml file

In controller file,

$om = \Magento\Framework\App\ObjectManager::getInstance();
$persistor = $om->get('Magento\Framework\App\Request\DataPersistorInterface');
$data = array('test1','test2');
<!-- set data in persistor object -->
$persistor->set('coloroption', $data);

In template file,

<!-- get data in persistor object -->  

  $om = \Magento\Framework\App\ObjectManager::getInstance();
  $persistor = $om->get('Magento\Framework\App\Request\DataPersistorInterface');
  $colorOption =     $persistor->get('coloroption');
  print_r($colorOption);

How to Pass Data from Controller to .phtml File in Magento 2.1

--We can use \Magento\Framework\Registry in your Block or Controller.

/**
 * Core registry
 *
 * @var \Magento\Framework\Registry
 */
protected $_coreRegistry = null;

...
$this->_coreRegistry = $registry;
...
$this->_coreRegistry->register('voucherNumber', $voucherNumber);

//We can get
$this->_coreRegistry->registry('voucherNumber');

--After loading layout, get the block and set values in Controller.

/**
 * @var \Magento\Framework\App\ViewInterface $_view
 */


/**
 * @return void
 */
public function execute()
{
    $voucherNumber = 24566;
    $this->_view->loadLayout();

    $block = $this->_view->getLayout()->getBlock('your_block_name');
    if($block) {
        $block->setVoucherNumber($voucherNumber);
    }
    $this->_view->renderLayout();
}

--We can use setData() or getData() in our Block.

  //In your Block:
  public function getVoucherNumber()
  {
        if (!$this->hasData('voucherNumber')) {

            $this->setData('voucherNumber', $voucherNumber);
     }
     return $this->getData('voucherNumber');
  }

 //In your template:
 <?php $voucherNumber = $block->getVoucherNumber();?>

Sample: Pass model object via controller.

<?php

namespace Vendor\Module\Controller\Test;

class Index extends \Magento\Framework\App\Action\Action
{
    /**
     * @var \Magento\Framework\Registry
     */
    protected $_coreRegistry;
    /**
     * @var \Magento\Framework\Controller\ResultFactory
     */
    protected $_resultPageFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $pageFactory,
        \Magento\Framework\Registry $coreRegistry
    )
    {
        $this->_coreRegistry = $coreRegistry;
        $this->_resultPageFactory = $pageFactory;
        parent::__construct($context);
    }

    public function execute()
    {
        //Get ID and create model
        $entityId = $this->getRequest()->getParam('entity_id');
        $model = $this->_objectManager->create('Vendor\Module\Model\VoucherEntity');
        if($entityId) {
            $model->load($entityId);
            if(!$model->getId()) {
                $this->messageManager->addError(__('This entity no longer exists.'));
                /** \Magento\Backend\Model\View\Result\Redirect $resultRedirect */
                $resultRedirect = $this->resultRedirectFactory->create();
                return $resultRedirect->setPath('*/*/');
            }
        }

        /** @var \Magento\Framework\View\Result\Page $resultPage */
        $resultPage = $this->_resultPageFactory->create();
        //Register model to use later in blocks
        $this->_coreRegistry->register('voucher_entity', $model);
        return $resultPage;
    }
}

In your Block, you can get:$this->_coreRegistry->registry('voucher_entity');
