Redirect customer to product page from where customer logged in to website Magento 2

Question

In Magento 2, I have a custom login form in Header.

If a customer is on the product page for eg :

http://www.testwebsite.com/catalog/product/view/id/10

and login from header form then customer should redirect to the same product page instead of Customer Dashboard.

I have tried plugin code from this link.

Below is my custom header form code -

<?php 

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$customerSession = $objectManager->get('Magento\Customer\Model\Session'); 

$urlInterface = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\UrlInterface');
$currenturl =  $urlInterface->getCurrentUrl();

if(!$customerSession->isLoggedIn()) {?>
<div class="header-login-main">
    <form action="<?php echo $this->getUrl('customer/account/loginPost');?>" method="post" id="login-form" novalidate="novalidate">
        <input name="form_key" value="" type="hidden">
        <div class="header-login" style="">
            <span>Email</span>
            <input name="login[username]" id="email" class="input-text" title="Email" data-validate="{required:true, 'validate-email':true}" aria-required="true" type="email">
        </div>
        <div class="header-login">
            <span>Password</span>
            <input name="login[password]" id="pass" class="input-text" title="Password" data-validate="{required:true}" aria-required="true" type="password">

        </div>
        <div class="header-login1">
            <button type="submit" class="action login primary" name="send" id="send2"><span>Login</span>
        </div>
    </form>
    <a href="<?php echo $this->getUrl('customer/account/forgotpassword');?>" class="f-right" style="padding: 3px 5px;">Reset Your Password?</a>
</div>

<?php } ?> 

Plugin Code -

<?php
namespace Vendor\Module\Plugin;
class LoginPostPlugin
{

    /**
     * Change redirect after login to home instead of dashboard.
     *
     * @param \Magento\Customer\Controller\Account\LoginPost $subject
     * @param \Magento\Framework\Controller\Result\Redirect $result
     */
    public function afterExecute(
        \Magento\Customer\Controller\Account\LoginPost $subject,
        $result)
    {
        $result->setPath('/'); // Change this to what you want
        return $result;
    }

}

I want to redirect the customer to $currenturl. Link tutorial can be able to redirect to the home page. Please suggest what needs to be done to achieve to redirect the customer to the current page.

Try the below:

Header Login Form :-

<?php 

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$customerSession = $objectManager->get('Magento\Customer\Model\Session'); 

$urlInterface = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\UrlInterface');
$currenturl =  $urlInterface->getCurrentUrl();

if(!$customerSession->isLoggedIn()) {?>
<div class="header-login-main">
    <form action="<?php echo $this->getUrl('customer/account/loginPost');?>" method="post" id="login-form" novalidate="novalidate">
        <input name="form_key" value="" type="hidden">
        <input type="hidden" name='referer' value="<?php echo $currenturl ?>">
        <div class="header-login" style="">
            <span>Email</span>
            <input name="login[username]" id="email" class="input-text" title="Email" data-validate="{required:true, 'validate-email':true}" aria-required="true" type="email">
        </div>
        <div class="header-login">
            <span>Password</span>
            <input name="login[password]" id="pass" class="input-text" title="Password" data-validate="{required:true}" aria-required="true" type="password">

        </div>
        <div class="header-login1">
            <button type="submit" class="action login primary" name="send" id="send2"><span>Login</span>
        </div>
    </form>
    <a href="<?php echo $this->getUrl('customer/account/forgotpassword');?>" class="f-right" style="padding: 3px 5px;">Reset Your Password?</a>
</div>

<?php } ?> 

Plugin Code : -

<?php
namespace Vendor\Module\Plugin;
class LoginPostPlugin
{
    protected $request;
    public function __construct(
       \Magento\Framework\App\RequestInterface $request
    ) {
       $this->request = $request;
    }
    public function getPostReferer()
    {
        return $this->request->getPostValue('referer');
    }

    /**
     * Change redirect after login to home instead of dashboard.
     *
     * @param \Magento\Customer\Controller\Account\LoginPost $subject
     * @param \Magento\Framework\Controller\Result\Redirect $result
     */
    public function afterExecute(
        \Magento\Customer\Controller\Account\LoginPost $subject,
        $result)
    {
        $result->setPath($this->getPostReferer());
        return $result;
    }    
}
