How to save custom data in cache in Magento 2

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.

Magento 2 introduced a new and improved way for adding products to the cart.

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!

Overriding classes in Magento 2

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

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

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.
