I am trying to overriding the below class in my custom module:

vendormagentomodule-customerControllerAccountLoginPost.php

For overriding this I have created the Plugin file as per the below Magento 2 official reference:

http://devdocs.magento.com/guides/v2.0/extension-dev-guide/plugins.html

I have created the app/code/Vendor/MyModule/etc/di.xml file:

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <type name="MagentoCustomerControllerAccountLoginPost">

        <plugin name="MyCucomtLoginAccountLoginPost" type="VendorMyModulePluginCustomerLoginPost" sortOrder="10" disabled="false"/>

    </type>

</config>

Now, I have written the below is aroundExecute method to achieve my customization:

appcodeVendorMyModulePluginCustomer

<?php



namespace VendorMyModulePluginCustomer;



class LoginPost

{

    public function aroundExecute(MagentoCustomerControllerAccountLoginPost $subject, Closure $proceed)

    {   

        //echo 'here'; die;

        if (isset($login['press_room_page'])) {

            $custom_redirect=true;

            }

        if (isset($login['press_room_page']) && $custom_redirect) {



            $resultRedirect = $this->resultRedirectFactory->create();

            $resultRedirect->setPath('mycustomlogin/index');

            return $resultRedirect; 

        }

    }

}

?>

The above code is working fine when I am print something "here" it means the file is override successfully.

Now I am adding my logic in the execute method below is original file of vendor which I have edited for testing purpose to check the logic work or not:

            } else {

                $this->messageManager->addError(__('A login and a password are required.'));

            }

        }

        if (isset($login['my_custom_page']) && $custom_redirect) {

            $resultRedirect = $this->resultRedirectFactory->create();

            $resultRedirect->setPath('mycustomlogin/index');

            return $resultRedirect; 

        }

        return $this->accountRedirect->getRedirect();

    }

}

Please see the below image to better understand what I have added my logic:

Please see below is second image to written logic for redirect user to again if they enter wrong username or password:

Below is the main moto for override the controller:

I have created the custom login page for specific customer group, they will login from the custom design page, so I have created the mycustomlogin.phtml in my module like: appcodeVendorMyModuleviewfrontendtemplatesmycustomlogin.phtml and passed the hidden input field value in the form for check where user had posted the form. I have get the hidden input value in AuthenticationException $e to check. if user have posted the form from custom design.

Anyone can suggest me how I can add my logic into the Plugin file?

Thanks!

You need to rewrite the customer loginPost plugin file as per the below

<?php



namespace VENDORMYMODULENAMEPluginCustomer;



class LoginPost

{

    public function __construct(

        MagentoFrameworkAppActionContext $context

    ) {

        $this->_request = $context->getRequest();

        $this->_response = $context->getResponse();

        $this->resultRedirectFactory = $context->getResultRedirectFactory();

        $this->resultFactory = $context->getResultFactory();

    }



    public function aroundExecute(MagentoCustomerControllerAccountLoginPost $subject, $proceed)

    {           

        $login =  $this->_request->getPost('login');     

        $custom_redirect= false;



        $returnValue = $proceed();            



        if (isset($login['press_room_page'])) {

            $custom_redirect=true;

        }

        if (isset($login['press_room_page']) && $custom_redirect) {

            $resultRedirect = $this->resultRedirectFactory->create();

            $resultRedirect->setPath('mycustomlogin/index');

            return $resultRedirect; 

        }

        return $returnValue;

    }

}

You can use after execute plugin and after that you can check either customer is login or not if not than you can redirect to your press page url

namespace VendorMyModulePluginCustomer;



class LoginPost

{

    public function afterExecute(MagentoCustomerControllerAccountLoginPost $subject,$result)

    {   

       $objectManager = MagentoFrameworkAppObjectManager::getInstance();

       $customerSession = $objectManager->get('MagentoCustomerModelSession');

       if(!$customerSession->isLoggedIn()) {

          // redirect to press page

       }

    }

}

According to @lavanya answer, the best way indeed is to use the plugin interceptor, I wanted to add a full answer and in more clean.

        $login =  $this->_request->getPost('login');

        $custom_redirect= false;

        if (isset($login['press_room_page'])) {

            $custom_redirect=true;

        }

        /*Execute code after the original function*/

        if ($custom_redirect) {
