magento2 – How to override a method in a vendor module?

Hi so i wrote this code to override a method in the woom cmstree module. But it seems like, something is wrong and i have used an entire day to figure it out, without any success.

My Vendor/MyModule/Block/Widget/Children.php

<?php

namespace VendorMyModuleBlockWidget;

class Children extends WoomCmsTreeBlockWidgetChildren

{

protected $belongsToMenu = "";

public function prepareLinks($treeChildren, $first = false)
{
    $html = '';

    some random code

    return $html;
}
}

My etc/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="WoomCmsTreeBlockWidgetChildren" type="VendorMyModuleBlockWidgetChildren" />
</config>

So this is how i did it. And i of course got the registration file and module.xml

But when i go to the page where this widget is used i get this error

(2021-03-04 20:56:22) main.CRITICAL: Error: Class 'VendorMymoduleBlockWidgetChildren' not found in /home/sonose2/public_html/generated/code/Vendor/Mymodule/Block/Widget/Children/Interceptor.php:7

I have been look at some examples but the are exact as mine and i have been trying alot of other stuff and now i ran out of ideas what to do.

magento2 – Adding Google Web Font to Transactional Email?

I’m attempting to add a Google Web Font (Montserrat: https://fonts.google.com/specimen/Montserrat?preview.text_type=custom) in the Marketing -> Email Templates area and attempted to add this in two ways.

I added the <link .. /> element in the <header> and also tried adding an @import rule in the box that allows you to add styles in the Email Template section of the admin panel.

Am I doing this wrong? The font is not showing on my sales emails. Thank you.

magento2 – Product are not displaying on Category page after Data Migration

For this you need to change into database set only is_filterable_in_search to 0

This is old code

SELECT *
FROM catalog_eav_attribute cea
JOIN eav_attribute ea
ON ea.attribute_id = cea.attribute_id 
AND backend_type IN ('text')
WHERE 
cea.is_filterable = 1 OR cea.is_filterable_in_search = 1

Replace with below one code with your prefix like.

UPDATE **prefix_**catalog_eav_attribute cea 
JOIN **prefix_**eav_attribute ea
ON ea.attribute_id = cea.attribute_id
AND backend_type in ('text')
SET 
cea.is_filterable = 0, cea.is_filterable_in_search = 0
WHERE 
cea.is_filterable = 1 OR cea.is_filterable_in_search = 1

Now after that just do reindex and cache

magento indexer:reindex
magento cache:clean
magento cache:flush

That’s it..

magento2 – Assign images to products programmatically

I want to assign images to products in my store

I put my php file in root/pub and tried this code:

public function launch()
{
$state = $this->_objectManager->get(‘MagentoFrameworkAppState’);
$state->setAreaCode(‘adminhtml’);

    $galleryReadHandler = $this->_objectManager->create('MagentoCatalogModelProductGalleryReadHandler');
    $imageProcessor = $this->_objectManager->create('MagentoCatalogModelProductGalleryProcessor');
    $productGallery = $this->_objectManager->create('MagentoCatalogModelResourceModelProductGallery');

    /**
     * Assumed images are named (sku).(ext) and reside in ROOT/pub/media/(image_dir)
     */
    foreach (glob(__DIR__ . "/media/img/*.{jpg,png,gif}", GLOB_BRACE) as $image) {
        $imageFileName = trim(pathinfo($image)('filename'));
        $sku = $imageFileName;
        try {
            $product = $this->_objectManager->create('MagentoCatalogModelProduct')->loadByAttribute('sku', $sku);
            if ($product) {
                $galleryReadHandler->execute($product);

                // Unset existing images
                $images = $product->getMediaGalleryImages();
                foreach($images as $child) {
                    $productGallery->deleteGallery($child->getValueId());
                    $imageProcessor->removeImage($product, $child->getFile());
                }

                /**
                 * Add image. Image directory must be in ROOT/pub/media for addImageToMediaGallery() method to work
                 */
                $product->addImageToMediaGallery('img' . DIRECTORY_SEPARATOR . pathinfo($image)('basename'), array('image', 'small_image', 'thumbnail'), false, false);
                $product->save();
                echo "Added media image for {$sku}" . "n";
            }
        } catch (Exception $e) {
            echo $e->getMessage();
        }
    }
    return $this->_response;
}

public function catchException(MagentoFrameworkAppBootstrap $bootstrap, Exception $exception)
{
    echo $exception->getMessage();
    return false;
}

}

/** @var MagentoFrameworkAppHttp $app */
$app = $bootstrap->createApplication(‘AssignImages’);

But display this error:

magento2 – Error 404 on Magento 2.4.2 on Localhost

I have set up a localhost installation of Magento 2.4.2 community edition, now I am getting this error: 404 Not Found.

I’ve got elasticsearch installed, a mysql database created but I can’t even access the mainpage of magento 2.4.2.

I have magento set up on /var/www/html/magento/ and this is my /etc/apache2/apache2.conf configuration:

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#   /etc/apache2/
#   |-- apache2.conf
#   |   `--  ports.conf
#   |-- mods-enabled
#   |   |-- *.load
#   |   `-- *.conf
#   |-- conf-enabled
#   |   `-- *.conf
#   `-- sites-enabled
#       `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.


# Global configuration
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE!  If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.

# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.

# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here.  If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.

#
# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"

magento2 – How to create an Observer for the OrderCommentSender class

I need to create an observer of the vendor/magento/module-sales/Model/Order/Email/Sender/OrderCommentSender.php class, at the send() method (83th line), so that I can append a customized comment in the comments section.

Line 83 starts at $this->eventManager->dispatch

public function send(Order $order, $notify = true, $comment = '') {

$this->identityContainer->setStore($order->getStore());

$transport = (
    'order' => $order,
    'comment' => $comment,
    'billing' => $order->getBillingAddress(),
    'store' => $order->getStore(),
    'formattedShippingAddress' => $this->getFormattedShippingAddress($order),
    'formattedBillingAddress' => $this->getFormattedBillingAddress($order),
    'order_data' => (
        'customer_name' => $order->getCustomerName(),
        'frontend_status_label' => $order->getFrontendStatusLabel()
    )
);

$transportObject = new DataObject($transport);

/**
 * Event argument `transport` is @deprecated. Use `transportObject` instead.
 */
$this->eventManager->dispatch(
    'email_order_comment_set_template_vars_before',
    ('sender' => $this, 'transport' => $transportObject->getData(), 'transportObject' => $transportObject)
);

$this->templateContainer->setTemplateVars($transportObject->getData());

return $this->checkAndSend($order, $notify); }
