Interceptor generation error: The requested class did not generate properly, because the 'generated' directory permission is read-only. If --- after running the 'bin/magento setup:di:compile' CLI command when the 'generated' directory permission is set to write.

I also want to save the form data custom db table named "prescription_form"

My Controller code is:

<?php

namespace Softadroit\Prescription\Controller\Index;

use Magento\Framework\Controller\ResultFactory;
use Magento\Framework\App\ObjectManager;

class Save extends \Magento\Framework\App\Action\Action
{       
    protected $_pageFactory;

    protected $_postFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $pageFactory,
        \Softadroit\Prescription\Controller\Index $postFactory
        )
    {
        $this->_pageFactory = $pageFactory;
        $this->_postFactory = $postFactory;
        return parent::__construct($context);
    }
    
    public function execute()
    {
        $post = $this->getRequest()->getPost();
        
        
        if (!empty($post)) {
            $name   = $post['name'];
            $age    = $post['age'];
            $weight = $post['weight'];
            $height = $post['height'];
            $gender = $post['gender'];
            $product_id = $post['product_id'];
            $customer_id = $post['customer_id'];
        
            $model = $this->_objectManager->create('Softadroit\Prescription\Model\Prescription');           
            /* $model->setName($name);
            $model->setAge($age);
            $model->setWeight($weight);
            $model->setHeight($height);
            $model->setGender($gender);
            $model->setGender($product_id);
            $model->setGender($customer_id); */
            $model->setData([
                    "name" => $name,
                    "age" => $age,
                    "weight" => $weight,
                    "height" => $height,
                    "gender" => $gender,
                    "product_id" => $product_id,
                    "customer_id" => $customer_id
                    ]);
        
        /* echo "<pre>";
        print_r($model);
        die(); */
            
             $msg ="";
             $data =  $model->save();
            if($data != ''){ 
                //$model->save(); 
                $this->messageManager->addSuccessMessage('Thanks your form is submitted successfully!');
            }else{ 
                $this->messageManager->addSuccessMessage('Error in submitting data. Please contact on this email!'); 
            } 
            echo $msg; 
            
            // Redirect to your form page (or anywhere you want...)
            $resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
            $resultRedirect->setUrl('/prescription/index');
            return $resultRedirect;
        }
       
        $this->_view->loadLayout();
        $this->_view->renderLayout();
    }
}

Resource model code:

<?php
namespace Softadroit\Prescription\Model\ResourceModel;


class Prescription extends \Magento\Framework\Model\ResourceModel\Db\AbstractDb
{
    
    public function __construct(
        \Magento\Framework\Model\ResourceModel\Db\Context $context
    )
    {
        parent::__construct($context);
    }
    
    protected function _construct()
    {
        $this->_init('prescription_form', 'id');
    }
    
}

Model code:

<?php
namespace Softadroit\Prescription\Model;
class Prescription extends \Magento\Framework\Model\AbstractModel implements \Magento\Framework\DataObject\IdentityInterface
{
    const CACHE_TAG = 'prescription_form';

    protected $_cacheTag = 'prescription_form';

    protected $_eventPrefix = 'prescription_form';

    protected function _construct()
    {
        $this->_init('Softadroit\Prescription\Model\ResourceModel\Prescription');
    }

    public function getIdentities()
    {
        return [self::CACHE_TAG . '_' . $this->getId()];
    }

    public function getDefaultValues()
    {
        $values = [];

        return $values;
    }
}

HTML template code I used to make form:

<?php
// Get all visible items in cart
$quote = $block->getQuoteData();
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
?>

<div class="row">
    <div class="col-md-8">
        <form name="addData" method="post" id="addData" class="form" action="<?php echo $this->getFormAction(); ?>" data-hasrequired="<?= $block->escapeHtmlAttr(__('* Required Fields')) ?>" data-mage-init='{"validation":{}}'>
        <?php foreach($quote->getAllVisibleItems() as $_item) { 
            $product = $objectManager->create('Magento\Catalog\Model\Product')->load($_item->getProductId());
            $customerId = $block->getLoggedinCustomerId();
            //echo $product->getPrescription(); //die();
            $is_priscription = $product->getData('prescription');
            if($is_priscription != "" && $is_priscription == '5431'){  // change prescription option id here ?>

Step: 1

Please change the code in controller file as below

From:

protected $_postFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $pageFactory,
        \Softadroit\Prescription\Controller\Index $postFactory
        )
    {
        $this->_pageFactory = $pageFactory;
        $this->_postFactory = $postFactory;
        return parent::__construct($context);
    }

To:

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $pageFactory,
        \Magento\Checkout\Model\CartFactory $cartFactory
        )
    {
        $this->_pageFactory = $pageFactory;
        $this->cartFactory = $cartFactory;
        return parent::__construct($context);
    }

After that run php bin/magento setup:upgrade And then you can run php bin/magento setup:di:compile

Step 2:

Change the code in controller section

From =

if (!empty($post)) {
            $name   = $post['name'];
            $age    = $post['age'];

            $height = $post['height'];
            $gender = $post['gender'];
            $product_id = $post['product_id'];
            $customer_id = $post['customer_id'];
        
            $model = $this->_objectManager->create('Softadroit\Prescription\Model\Prescription');           
            /* $model->setName($name);

            $model->setGender($product_id);
            $model->setGender($customer_id); */
            $model->setData([

        /* echo "<pre>";
        print_r($model);
        die(); */

            $resultRedirect->setUrl('/prescription/index');
            return $resultRedirect;
        }

To=

    every attribute as an array. like $post['name'] is an array so you have to use foreach for every data. Aug 24 '20 at 17:25
  • I want to clear quote after submitting this form so what I have to do?
