Programming? Aren’t 80% of the articles programming related? Well, yes. However, there are some that are really related to programming style, best practices, etc or ones that we couldn’t place anywhere else.

How to programmatically create customers in Magento 2.3.x

By: Deni Pesic, Last updated: Aug 28, 2023 | Published: May 08, 2020

There are several ways to create customers in Magento 2. A customer can create an account on their own using the sign-up form, a customer can be created through the admin interface, and there is even a built-in Magento 2 import feature that can mass import a huge number of customers from a CSV file, provided that the customer data in the CSV is import-ready.

But what if we have thousands of customers whose data still needs to be processed before they can be created? The best way to do this would be to create the customers programmatically.

In this article, we are going to cover the topic of creating customers programmatically, and to this purpose, we are going to create a simple Magento 2 module which is going to have a custom console command and a couple of models that are going to be used to read, process and create customers.

Logging is an important part of every development process. Logs provide insight into system processes of Magento 2 and are a great tool for tracking errors, significant events, exceptions and many more. In order for the logging library to be properly implemented with Magento 2, it must comply with PSR-3 standard.

Magento 2 comes with built-in logging solution based on Monolog Library which will be analyzed further in this article.

How to save custom data in cache in Magento 2

By: Lukas Scharmitzer, Last updated: Aug 28, 2023 | Published: Jul 30, 2019

Recently I was working on rendering images on a custom template. More precisely, I created a widget for inserting pictures that serve as a picture loader. And by default, the administrator has to input some parameters (width, height, alt) and if he decides, he could upload another image.

Reference for creating a widget tutorial could be seen here. The exciting part of the task was when the widget is saved on some of the Magento pages and loaded on i.e. ‘About Us’, image or images and parameter values have to be saved in the cache.

So when you visit ‘About Us’ another time, image content will be served instantly.

In this article, we’re going to save simple custom data inside the cache and load it when Magento renders the template.

How to improve usability for Magento 2 add to cart process

By: Filip Svetlicic, Last updated: Aug 29, 2023 | Published: Feb 05, 2018

Magento 2 introduced a new and improved way for adding products to the cart. The system now offers complete asynchronous (ajax) process, although the process itself is not activated in default application state. It requires some manual adjustments in the script call inside the templates. Someone would think, ok, we will simply modify the template script calls and that’s it! We successfully improved the process. Unfortunately, not so fast! There is still more room left for improvement. If you’re interested, let’s find out what’s left on the table.

The Fastly CDN will sometimes return a 503 error due to various issues that can occur. The generic text associated with a 503 error is “Service Unavailable” and it can mean variety of things. This default error response can be confusing to the customers and have a basic look and feel.

Pagination with rel=”next” and rel=”prev” in Magento 2

By: Sasa Brankovic, Last updated: Sep 18, 2019 | Published: May 10, 2017

Out of the box, Magento 2 offers fair amount of search engine optimization options but when it comes to category pages, we only have option to add canonical meta tags. In today’s blog post, we will try to spice that up a bit by implementing our own variation of canonical tag and by adding rel=”next” and rel=”prev” tags to help bots with paginated content.

Overriding classes in Magento 2

By: Damir Korpar, Last updated: Oct 07, 2019 | Published: Jan 04, 2017

Compared to its previous version, Magento 2 came out with a new concept of dependency injection where classes inject dependencies (different objects) for an object instead of that object manually creating them internally. That way overriding and manipulating with classes is much easier and allows us more ways of extending the native functionalities.

File upload in Magento 2 store configuration

By: Luka Rajcevic, Last updated: Sep 14, 2017 | Published: Nov 03, 2016

One of the best parts in Magento is its admin interface. There is support for all kinds of input types (text fields, radio buttons, dropdowns, multiple selects, etc.), that can be stored in various ways (plain, encrypted, serialized), and displayed in numerous ways (grids, forms, simple fields, images).

What makes Magento great is the possibility to extend this default interface (especially store configuration part), and add our own fields easily. Let’s extend it with a custom file upload field.

Add new console command in Magento 2

By: Luka Rajcevic, Last updated: Aug 28, 2023 | Published: Mar 02, 2016

Remember that time when you wanted to create a Magento shell or php script to perform some action, but didn’t know where to put it?
Remember the /shell folder in root Magento installation (or root folder, for that matter)?
Remember how it used to have, like, 50 shell and php scripts all mixed up, and you get a headache just by looking at them?
Pepperidge Farm remembers.

Those were good old times, and like all good times, they have now come to pass. There’s a new kid on the block, more powerful and way cooler, and the best part is – it’s integrated into Magento 2.

Interactive Bash script for managing themes in Magento 2

By: Danijel Vrgoc, Last updated: Mar 19, 2020 | Published: Feb 04, 2016

Do you remember, how many times you did something that was time consuming and/or required certain amount of steps to achieve your goal? After some time you had to repeat the whole process… And again… And again… I am pretty sure you came to an idea, “Wouldn’t it be really useful if I can somehow simplify the process?” Yes, you are correct, the same question troubled me when trying to figure out how the make my life easier when creating a custom theme. Unlike Magento 1, Magento 2 has a different (and more complex) way of setting up themes, so I started developing a Bash script that will make my life easier. Hopefully, yours as well.

Magento 2 Controllers

By: Zoran Salamun, Last updated: Sep 23, 2019 | Published: Oct 01, 2015

Controllers in Magento 2, like on other PHP MVC frameworks, are important part of Mvc flow. In Magento 2 there are lots of changes in controllers, for example; how they are structured and how they work compared with Magento 1. If you are familiar with Magento 1 controllers, then you know they can have multiple actions (class methods). In Magento 2 controllers have only one method (execute) that will be called by front controller. This article covers controller basics, matching flow, controller types (admin and frontend), changes on existing controllers, instructions to create custom controllers and an example how to create a few controllers.

Implementing payment gateway in Magento 2

By: Stjepan Udovicic, Last updated: Oct 15, 2019 | Published: Jul 24, 2015

This is a revised article originally written in September 2014 when I started to play with Magento 2 for the first time. Since there were a lot of changes in Magento 2, this article also needed some refreshment. We will glance over the backend, and proceed with the development of a simple module. For this task, I picked up the payment gateway API integration. This relatively simple task will help us demonstrate some key changes in Magento 2.

More precisely, we will be focusing on implementation of Stripe payment gateway. Even though Stripe has a rich set of features, here we will be focusing only on most basic functionalities to get you started with Magento 2 extension development.
