Customizing pagination templates in Laravel 5.3
Jul 27, 2016 @ 12:33:36

Matt Stauffer is back with another in his series of posts about the new features coming in the v5.3 release of the popular Laravel framework. In the latest post he looks at pagination improvements allowing you to customize the related templates.

Laravel's pagination library is brilliant, because pagination is a common task that is a surprising amount of work to implement. In the past, if you wanted to customize your pagination templates, it was just as simple to customize your pagination template as it was to work with the rest of the pagination library.

However, for the sake of making the pagination library easier to extract for non-Laravel projects, Laravel 5.0 (or maybe even earlier?) introduced a much more complex—but more portable—system for pagination templates. Thankfully, in Laravel 5.3, we're going to go back to how it always was: simple and easy.

He then gets into the basics of how pagination works in Laravel applications (not the template part, the backend) using the Task::paginate handling. He includes the view to just show the results and the current view handling for the pagination links. Finally he shows how to customize the template in v5.3 by registering a custom view to the partials.paginator and using the links method to inject them into your current template.

Loïc Faugeron:
Mars Rover, Event Sourcing package
Jul 27, 2016 @ 11:51:05

Loïc Faugeron has continued his "Mars Rover" series in his latest post today. This series, based on a set of specifications from a development challenge. In this latest post he continues looking at event sourcing and creates a package to handle the eventing to make it more flexible and robust.

In this series we're building the software of a Mars Rover, according to the following specifications. It will allow us to practice the followings: Monolithic Repositories (MonoRepo), Command / Query Responsibility Segregation (CQRS), Event Sourcing (ES) Test Driven Development (TDD).

Up until now, we've implemented the first use case, "Landing a rover on Mars" [and] in the last article, we wrote some Event Sourcing code. [...] In this article, we're going to extract them from the navigation package and put them in their own event-sourcing package.

He starts by creating the package itself as a Composer package including the composer.json configuration and a few other files to have phpspec work correctly. He then adds the event-sourcing package to the main project and starts in on using phpspec to generate its basic files. He then updates the main Lander class to use this new package for events. There's no code in the eventing classes yet, but stay tuned for the next tutorial in the series that will update them and get it all working together.

Mars Rover, Landing event
Jul 20, 2016 @ 09:33:05

Loïc Faugeron has posted the latest tutorial in his series about developing a "Mars Rover" script using various design patterns and principles. In this latest part of the series he looks at handling the "landing event" of the rover.

In this series we're going to build the software of a Mars Rover, according to the following specifications. [...] Previously we've created a navigation package, and in it a LandRover class that validates input parameters for our first use case. [...] We've then refactored it to extract coordinates and orientation in their own classes.

In this article we're going to create the actual landing logic, using Event Sourcing

He then starts in, creating the tests first because of TDD, on the LandRoverHandler to integrate a command architecture (using the Command Bus pattern). He then sets up the structure for the event sourcing and an basic event for the landing of the rover. This includes the handler for the event, the event itself and the storage method for capturing that the event happened. He fills in the generated classes with a bit of logic and a few updates to the test for the new structure.

How to Program With Yii2: Uploading Files
Jul 15, 2016 @ 12:15:45

On the TutsPlus.com site there's a new installment in their "How to Program With Yii2 Series" looking at implementing file uploads with some simple examples.

In this How to Program With Yii2 series, I'm guiding readers in use of the Yii2 Framework for PHP. In this tutorial, I'll guide you through the basics of uploading files and images in Yii2.

For these examples, we'll continue to imagine we're building a framework for posting simple status updates, e.g. our own mini-Twitter. The image above demonstrates writing a short update while uploading a picture I took of the Taj Mahal.

They start with a look at some of the file upload plugins that seemed like the best they found to use with Yii2: FileInput and the 2Amigos BlueImp File Uploader. They go with the first option for the rest of the tutorial, showing you how to get it installed (via Composer), updating your current database tables and changing the model to reflect these updates. Next they help you create the view with the image upload form and one to display the image result once the upload is successful (including the controller code needed).

Advanced operations with Collection::where in Laravel 5.3
Jul 15, 2016 @ 11:35:44

Matt Stauffer has continued his series looking at new features in Laravel 5.3 with a look at advanced operations on collections, specifically related to the "where" handling.

If you want to filter a Laravel collection to only those records which meet particular criteria, you're most likely going to reach for filter() or reject(). [...] You might not know it, but there's also a where() method that's pretty simple that gives you the same functionality.

He points out the main difference in Laravel 5.3 - the change from a strict check (the ===) to looser checking (==) and the ability to modify the operation to your liking. He also links to more information about this and other methods in the Laravel code on GitHub.

Loïc Faugeron:
Mars Rover, Landing orientation
Jul 13, 2016 @ 10:40:41

Loïc Faugeron is back again with the next part of his "Mars Rover" series of tutorials. In this new article he refactors the current code even more to make it more flexible in the long run.

In this series we're going to build the software of a Mars Rover, according to the following specifications. It will allow us to practice the followings: Monolithic Repositories (MonoRepo), Command / Query Responsibility Segregation (CQRS), Event Sourcing (ES) and Test Driven Development (TDD). Previously we've created a navigation package, and in it a LandRover class that validates input parameters for our first use case.

We've also started to refactor it by extracting coordinates in their own class. In this article we're going to further refactor LandRover

He found that the coordinates could become floats (or have additional values) and that the orientation could become an angular degree/be vertical. To help this situation, he pulls this logic out into an Orientation class. True to the TDD methods, he starts with the phpspec test and generates the skeleton class based on them. He makes some simple edits to make the tests pass and updates the main LandRover class to use the new Orientation class for these positions.

SitePoint PHP Blog:
PHP, Arduino, And… Minecraft? Connecting an Arduino to PHP!
Jul 12, 2016 @ 10:39:38

The SitePoint PHP blog has continued their series looking at connecting the real world with the online world via Minecraft and an Arduino. In this new post author Christopher Pitt picks up where he left off in part one and brings the Arduino in to the picture.

In the first part of this series, we learned a bit of Minecraft and the circuitry we can make inside it. We also made a circuit to alert us when the door to our mansion was opened. We then hooked this virtual alarm to a listening PHP script, so we can know when the door is opened in the context of a PHP script.

In this part, we’ll build a small Arduino-based alarm circuit. We’ll learn how to trigger the alarm, using the the official IDE and programming language, and then using something called Firmata. We’ll round the series out by connecting the alarm circuit to the Minecraft circuit, so we hear a real alarm for Minecraft mansion.

He takes some time at the beginning of the post introducing the Arduino hardware and what they have to offer. He lists the parts you'll need for this setup to work and how they need to be set up. He then gets into the code for the Ardunio side and how to get it over to the board. He presents another option to the potentially painful change-reupload cycle of debugging Arduino code: using the PHP "carica/firmata" library to connect to and add listeners to hook into the board. He uses this to then set up a PHP script to watch for changes in the Minecraft log files and fire an event to the waiting Arduino board.

The final item in this part of the tutorial series talks about bringing in the "Gorilla" extension for Carica Firmata to help prevent issues with too fast connections to the board interrupting the boot sequence.

New JSON-column where() and update() syntax in Laravel 5.3
Jul 11, 2016 @ 11:03:49

In his continuing series of posts looking at the new features in Laravel 5.3, Matt Stauufer has posted this guide to the use in the new JSON column functionality MySQL now provides in recent versions.

While Laravel has had the ability to cast your data to and from JSON since version 5.0, it was previously just a convenience—your data was still just stored in a TEXT field. But MySQL 5.7 introduced an actual JSON column type.

Laravel 5.3 introduces a simple syntax for lookups and updates based on the value of specific keys in your JSON columns.

He gives an example of a simple table with a JSON column storing some metadata for the entry. He includes a bit of example content showing the full entry and related metadata and the where format for querying it. It also includes the ability to run updates on the data just like with any other where clause.

Davey Shafik:
Community Relations: Not Just a Megaphone
Jul 11, 2016 @ 10:49:04

Davey Shafik has continued his series of posts with advice about growing a community around your product/open source libraries. In his first post he talked more about how to engage the community. In this latest post he talks about the role of "evangelists" in community relations (and why he dislikes the term).

The role of the Community Builder is to sell you on the idea of the company and the product. Not necessarily to sell you the product. Often times what we’re selling are not bought without some decision making process behind them, so a sale is not going to happen then and there anyway. Provide the education, and build the trust, and the sale will happen.

Davey then talks about why he hates the term "evangelist" and how it seems to relate more to "fanatic" than "advocate". He then gets into what he sees as the role of an advocate, including the role honesty plays and selling the customer on the right product. He then turns it around and talks about the other side of the role - advocating for the customer back to the rest of the company. Finally, he talks about two other kinds of advocacy that should also be included in the role: advocating for the community/their input and for yourself (finding a product you can be passionate about selling).

SitePoint PHP Blog:
PHP, Arduino And… Minecraft? Combining Minecraft with PHP!
Jul 07, 2016 @ 13:35:15

On the SitePoint PHP blog author Christopher Pitt has a new tutorial posted about combining PHP, Arduino and Minecraft and combine the physical and software worlds in an interesting IoT combination.

Some of the most interesting programming I’ve done has been in Minecraft. It’s an open-world, sandbox game developed by Mojang, (recently acquired by Microsoft). Minecraft began as a canvas for creative expression, and while I do very different things in it these days, it still is that for me.

I’m going to take you on a journey, as we build a Minecraft mansion, and then secure it with a real-world alarm system. There’s quite a bit of ground to cover, and though I plan for this to be a two-part series, I’m going to have to leave some of the tangential details for you to discover!

For those not familiar with "programming" in Minecraft (not the backend language, but using things like redstone) he gives a brief introduction. He then sets up the situation - the creation of a "sprawling mansion" in your Minecraft world and a need to secure the front door. He includes the command to set up the "door open" test on a command block. He then shows how to hook this into a loop to continuously test if a door is open or not. With this open/closed door check system in place he then brings PHP into the mix, having it check log files for the "whispers" when the door actions happen. He then creates a watcher for these events and has it respond with a chat message back to the user. That's all in this tutorial but a future part of the series will add on the physical aspect - the Arduino.
