Use \Magento\Catalog\Model\Product\Image\UrlBuilder, check out an example below.

You’re probably aware of the fact that Magento is a very heavy application. It is especially hard on database, and performs a lot of queries in order to function properly (which it does not a lot of times, unfortunately). Sooner or later, a need will arise for you to check what queries are being performed on the page. Either you’re hunting for the slow ones, or are trying to optimize their number. There is a simple way to have this working.

If you’re like me, you probably just fly through the Magento 2 installation, without actually reading anything. Usually, this is not an issue (especially if you’ve done it several times), but recently Magento has an addition with creating an administration url.

What can we do to implement a repeat email frontend validation?

Maybe you’ve noticed that Magento 2 does not allow you to reindex data from the administration side. Additionally, there is no script called ‘indexer.php’ or something like that, that you would usually call. How do you reindex manually then? Use magento command line tool:

Wouldn’t it be great if you could show all your coupons to customers on one page? This way they would know where to search for the coupons, and coupons would come from a reliable source - you. Also, you could advertise this page and get more customers to sign up because, well, you offer coupons only for registered customers. ^^ How would we go about doing something like this?

Let’s say you want your customer to change his password. Nice way to do it is to send him a ‘reset password’ email. Here is the snippet:

At times there is a need to switch the eCommerce platform you are working on. Reasons for this can be numerous. Your existing platform might be outdated, might be without any future improvements coming up, you might have heard great things about some other platform or simply you are not satisfied with the way your current platform works and behaves. Nevertheless, you’ve decided to do the switch. It is not an easy task to do because, in almost every case, platforms are not compatible with each other and in order to keep all of the data from previous platform (like your customers, orders, reviews etc.), some changes have to be performed on the data.

Sometimes a need arises for you to add additional attributes to the standard Magento API responses. While doing this in Mageno API v1 is fairly easy, as you will see soon, the v2 has some quirks that had to be found out the hard way, unfortunately. So in order for this to not happen again, here is the explanation. I will assume you already have your API roles set up, and you can invoke Magento API and get responses.

Everyone knows what a caching is, but to put it simply, it is a mechanism to store (save) data that is frequently accessed but rarely changed in order to have a faster response time.

One of the requirements from clients will likely be to change transactional emails. Whether they want to add some styling or add new informations, you will have to change the default emails. Sometimes the requirement involves showing products on emails, to increase marketing and in extend revenue.

I had this error on my local apache server. While trying to invoke some Magento API,apache log showed this error. To get rif of it, simply remove the MultiViews part in you apache virtualhost file. For me it was in

In the last few days I have been playing with the functionality of adding another fee to the checkout process. While exploring the topic I stumbled upon a lot of good tutorials for doing exactly that. Namely this, and this one. I read them and followed instructions stated there. With some changes, I managed to recreate the functionality I needed. But, while reading the comments for both articles, I saw the main trouble people had with them. The part about showing the fee or discount in email messages of orders, invoices and credit memos was missing (or not implemented), so here is how i did it.

Reward messages in magento are not coming from database. They are not coming from configuration in admin. They are not set in blocks nor templates. So where are they then?

Sometimes you would like to customize the page depenfing on the category. For example, you would like to change the header picture or change other things.

Magento search query, when entered in the form.mini.phtml (template/catalogsearch/form.mini.phtml) is doing the search on database in Mage_CatalogSearch_Model_Layer:prepareProductCollection().

Recently I got a new job (my first real one, actually), and it is revolving around PHP, i.e. Magento development. Before my first day at the job, I was wondering what kind of IDE or text editor should I use and what kind of one my future co-workers use. I emailed them and the response was just as I expected it to be: “full fledged IDEs like eclipse, netbeans or phpStorm”. I have had a lot of previous experience with those environments, mostly doing Java programming, and I was aware of all the bloat they bring. They were slow most of the time, they were laggy and pretty much uneasy to work with. Sure, that was the case on my own machine which is not really a “state of the art”, and I am sure they perform better on more powerful computers.

Just a regular function, which yields things (but can return them sometimes as well).

Streaming a large video file from your Symfony application is an interesting problem. We need to be able to serve data to the client continuously, as well as make sure memory footprint on server is not causing issues. Let’s take a look at a simple approach to solving this.

One of those weird function calls we see when reading internal code for majority of frameworks. ob_start() and ob_end_flush() may have caused some confusion, but no more. The thing is fairly straightforward.

Interesting nugget of PHP behaviour I was not aware of. Check it out.

Xdebug 3 has some major differences in configuration, when compared to older versions. I’m showing how to set it up on your dockerized environment.

Introduction

Bitcoinj is a library designed specifically to interact with Bitcoin network. You can use it to interact with real bitcoin blockchain, or play around in TestNet - bitcoin’s testing network. It allows us to do some pretty cool stuff. This post (and hopefully a series of them) is my way of trying to learn more about bitcoin, and its inner workings by using this library. For starters, I’d like to focus on simple tasks - creating a wallet, an address, and receiving some funds to it. This introduction assumes you’ll be able to download the library, and include it into Java project, either using Maven, or manually. Either way is fine.

When you’re working on many different servers, you might get tired of constantly looking for an IP address, or a password to log in. This makes the whole process very tiring.. Ctrl+R on linux can be helpful if you remember a part of the hostname, but remembering the password is almost impossible - of course if you use a secure one.

There are times when you need to zip your project, either for backup or whatever. You can always use tar or zip commands. But if you use git as a version control, there is a very simple way to achieve this.

So, you’re connected to a server via SSH, doing your wizardry and dark magic. Suddenly, a wild Pidgey appears. Just kidding.

You know what an email address is? I’m sure you do.. It’s a string of letters (and numbers) in a certain format (eg. with an @ symbol), that serves as your identification and also as a pointer as to where the message you’re sending should go. Bitcoin’s address is very similar, only instead of sending the message to it, you’re sending a different kind of information - Bitcoin.

I like to look at Bitcoin the same way as I look at gold. Here’s a quick explanation as to why.

Recently, my interest in large proportions switched to Bitcoin both from financial and technical standpoint. I’ve been reading a lot on the topic (be it books, forums, reddit discussions, youtube videos, various conference talks etc.). One thing I noticed, and it has been noted many times by many people (and very influential ones) in Bitcoin community, is the difficulty of “getting” the Bitcoin, and understanding what it is from the standpoint of a “regular” human - Homo Domesticus .

Things you should know about ruby regular expressions.

Strings in Ruby are, just like in other programming languages, objects for handling text. If you ever tried to write some Ruby code, you are familiar with them and their syntax. But this post is not about syntax that is well known. While reading through some ruby books and tutorials I found some pretty interesting ways of dealing with strings.

I’ve been going through Ruby Best Practices book lately and, while it covers a lot of interesting topics, one thing caught my eye. It was sub-chapter about memoization.

Memoization is an optimization technique used to speed up your programs by avoiding to repeat function calls for already calculated inputs.

Cool thing I ran into when watching Douglas Crockford’s talk on Javascript: the good parts was a different way of creating objects, with lot more options than usual way I was doing it. More specifically, I found it interesting to see that we can set certain properties as non-writeable ie. immutable.

Recently I have been playing with Ember.js. It is a javascript front-end framework for developing web applications. You can find more details and really thorough guides on their website. As my new blog post, I have decided to create a tutorial for building a simple markdown editor (in ember). Markdown, for those unaware of it, is a simple, lightweight markup language. I use it a lot for my github readme pages. While there are several great applications for editing markdown in real time out there, I thought it would be a good exercise to create one of my own, and since this is really easy to do in ember, I am showing it as a simple tutorial.

I have been reading about Hadoop in the last few weeks. I went through few books and articles, and wanted to try a more hands-on approach. So, while googling for examples I noticed that there is only one real simple example for Hadoop - Word count. This one is pretty easy, but it would not be really interesting to write another article about it. So, my example will be to count the sum of even and odd numbers in a file.

It feels like everyone in tech circles is talking about this, and even non-tech people got interested, and joined on the fun. ChatGPT - the man of the hour.
