Magento 2 Plugin – How to Override Block

blocksmagento2plugin

I want to override a _prepareLayout function of the block module-catalog-search/Block/Result.php .

 protected function _prepareLayout()
    {
        $title = $this->getSearchQueryText();
        $this->pageConfig->getTitle()->set($title);
        // add Home breadcrumb
        $breadcrumbs = $this->getLayout()->getBlock('breadcrumbs');
        if ($breadcrumbs) {
            $breadcrumbs->addCrumb(
                'home',
                [
                    'label' => __('Home'),
                    'title' => __('Go to Home Page'),
                    'link' => $this->_storeManager->getStore()->getBaseUrl()
                ]
            )->addCrumb(
                'search',
                ['label' => $title, 'title' => $title]
            );
        }

        return parent::_prepareLayout();
    }

In above function, if I want to change the breadcrumbs name from Home > Search Result to something else.
How can I do it with the help of plugin ?

Easiest solution is that use translations

Translation is simple way with doing less code:

Create a translation file at theme translation folder

app/design/frontend/[VendorName]/[Theme]/i18n/[Your_Lanague_Code].csv

and write code

"Search results for: '%1'", "My results for: '%1'"

See how use http://devdocs.magento.com/guides/v2.0/frontend-dev-guide/translations/translate_practice.html

Magento2 Module – Fix ‘main.CRITICAL: Plugin Class Doesn’t Exist’

I couldn't reproduce your error, but I got an other one.

Then I did some minor adjustments to your code and it worked.
First drop the InstallSchema.php file. It does nothing so it is useless.

Then make sure that your plugin file is in Amaj/CorePlugin/Model/Currency/Plugin.php and it looks like this:

<?php

namespace Amaj\CorePlugin\Model\Currency;

class Plugin
{
    protected $logger;

    public function __construct(\Psr\Log\LoggerInterface $logger) {
        $this->logger = $logger;
    }

    /**
     * @param $subject
     * @param \Closure $proceed
     * @param $price
     * @param array $options
     * @return string
     */
    public function aroundFormatTxt(
        $subject,
        \Closure $proceed,
        $price,
        $options = []
    )
    {
        $this->logger->info('Amaj aroundFormatTxt');
        return '2';
    }

}

you don't need parent::__construct(); in the constructor because there is no parent class.
And I replaced $logger->info with $this->logger->info because there is no $logger variable.
