Notifications in Laravel
Apr 24, 2018 @ 13:25:24

On the TutsPlus.com site they've posted a new tutorial for the Laravel users out there showing how to work with notifications, a feature build into the framework to make it simpler to provide information to users when certain events are triggered.

In this article, we're going to explore the notification system in the Laravel web framework. The notification system in Laravel allows you to send notifications to users over different channels. Today, we'll discuss how you can send notifications over the mail channel.

The tutorial starts with some of the basics of the notification system including a mention of the other methods (like SMS and Slack) and storing them in a database for other interaction. It then moves on to the creation of a Messages model and a custom notification class to send email to a when a new message is sent from another user. With the class created, they move into the process required to send the notification using the Notification::send method.

Laravel Exceptions: How to Catch, Handle and Create Your Own
Apr 23, 2018 @ 11:25:10

On the Laravel Daily site they've posted a tutorial showing the Laravel users out there how to create and catch custom exceptions in your application. Exceptions are a useful tool to handle "exceptional situations" where something fails badly enough where the application cannot proceed.

Quite often web-developers don’t care enough about errors. If something goes wrong, you often see default Laravel texts like “Whoops, something went wrong” or, even worse, the exception code, which is not helpful at all to the visitor. So I decided to write a step-by-step article of how to handle errors in elegant way and present proper error information to the visitor.

He uses a "user search" task to help illustrate the methods for creating custom exceptions, catch exceptions and showing the error to the user. Code is included as well as screenshots of the output. With the basics of exception handling out of the way, they move the handling off into a service and take it one step further to create a custom "user not found" exception and its use in the search method.

Sameer Borate:
Creating custom stream filters in PHP
Apr 11, 2018 @ 09:45:43

Sameer Borate has a new post to his site showing you how to create custom stream filters for use with the streams functionality already included in the PHP language. The streams handling provides a resource instance (filesystem, network connection, etc) that can be interacted with in a more standardized way.

In this post we will see how to create a custom stream filter. Streams, first introduced in PHP 4.3, provide an abstraction layer for file access. A number of different resources besides files – like network connections, compression protocols etc. can be regarded as “streams” of data which can be serially read and written to.

He shows how to get the current list of streams available and includes an example of one in use, the "string.strip_tags" filter. From there he shows the creation of a custom filter, one that replaces any URLs detected in a string with a string of [--URL--]. He includes the code for the filter and shows how to register it using the stream_filter_register function. He also includes an example of it in use, grabbing the contents of the BBC site and having the filter automatically applied.

Try PSR-12 on Your Code Today
Apr 10, 2018 @ 10:51:19

In a post to his site Tomas Votruba shows you how to test the PSR-12 standard on your current codebase using some custom PHP-CS-Fixer rules. The PSR-12 standard is a recommendation from the PHP-FIG group about consistency in coding styles and formatting. It expands and replaces the previous PSR-2 standard.

The standard is still behind the door, but feedback, before it gets accepted, is very important. After accepting it will be written down and it will be difficult to change anything.

Try PSR-12 today and see, how it works for your code.

Korvin Szanto, a developer working on the PHP-CS-Fixer project, has put together a commit with the rules to update and enforce the PSR-12 coding standard. The post shows how to install these rules and how to change up your YAML configuration to include them. He also includes a discussion about agreeing/disagreeing with the coding standard idea and gives examples of two rules he personally doesn't agree with.

Laravel News:
User Defined Schedules in Laravel
Mar 09, 2018 @ 11:43:31

On the Laravel News site there's a new post looking at the use of user-defined schedules and some of the "hidden" features the Laravel framework provides to allow for even more customization.

Recently Adam Wathan and Taylor Otwell have used Basecamp to track what they are doing every day–a tech diary. Notably, they are using the check-in feature which allows you to schedule questions to be sent to members about almost anything. Taylor and Adam are using it for “What did you work on today?”

It’s not that it’s the same time of day or even that it’s only weekdays which peaked my curiosity but the fact every check-in has a custom schedule defined by a user. In Laravel, we can quickly schedule a job to run every weekday at 4 pm, and we can use a custom timezone. But out of the box, we cannot set a different schedule for every individual check-in. We would have to store a cron expression and manually check every minute if it’s due.

After some "source code diving" the author figured out that the Schedulable trait allows you to define a more customized version of a schedule to fit your needs, making it simple to implement in any class or model. Code examples of these changes are included in the post as well as some next steps to have it implemented more widely either in the Laravel core or a package.

Gates and Policies in Laravel
Nov 20, 2017 @ 12:46:28

On the TutsPlus.com site there's a new tutorial posted for the Laravel users out there covering a few pieces of the authorization features of the framework. The tutorial covers "gates" and "policies", introducing some of their basic concepts and providing example code to implement your own.

Today, we're going to discuss the authorization system of the Laravel web framework. The Laravel framework implements authorization in the form of gates and policies. After an introduction to gates and policies, I'll demonstrate the concepts by implementing a custom example.

I assume that you're already aware of the built-in Laravel authentication system as that's something essential in order to understand the concept of authorization. Obviously, the authorization system works in conjunction with the authentication system in order to identify the legitimate user session.

The article starts by introducing some of the basic approaches the framework takes to authorization handling and where gates and polices fit in. It then gets into the details of each including example code showing how to define them based on the interfaces provided. The tutorial then shows how to put them to use in a simple application, applying them at both the controller and view level.

Jeff Madsen:
PhpStorm: Tasks & Contexts with Your Git Branches
Sep 26, 2017 @ 09:37:29

On his Medium.com site Jeff Madsen shows you how to use contexts in the PhpStorm IDE to switch between environments or current work using a more streamlined process.

Switching context is a pain.

Not just because you need to mentally switch the complex web of ideas in your head. Think about all the physical files on different git branches you have to remember in order to answer a “quick question about task #123”. [...] PhpStorm has a lot of great context links and shortcuts to help you navigate among all these, but it is still a royal pain whenever you need to put one set of files aside and work in a different area of the codebase.

[...] When I finished something and pushed it up for review if there was even a small request to change a default or label I had to reopen the branch and track down the correct files where the work was done. How could I turn that all into a single, easy step?

Enter Contexts and Tasks!

He starts off by defining what a "context" is in the world of PhpStorm - a group of open files with a name attached - and how they can be created/saved inside the IDE. Next is the idea of "tasks" that help with performing operations and relating them to contexts and groupings of files. He then shows how to switch between tasks related to a certain feature and how to close it out when you're done.

Asmir Mustafic:
How to add custom error codes to your Symfony API responses
Sep 22, 2017 @ 11:10:01

Asmir Mustafic has posted a guide on his site showing how to create custom error codes in the API responses from your Symfony-based application.

When writing APIs, a proper error handling is fundamental. HTTP status codes are a great start, but often when we deal with user inputs is not enough. If out model has complex validation rules, understanding the reason behind an 400 Bad Request error can be not trivial.

Fortunately when for symfony developers there are many libraries to deal with it. Symfony Validator, <a href="https://github.com/symfony/form>Symfony Form, <a href="https://github.com/FriendsOfSymfony/FOSRestBundle>FOS REST Bundle and JMS Serializer combined allows you to have nice error messages to be shown to your users.

He walks you through the code required to create the default error handling with an "author" example. This includes the creation of the entity as well as the form and controller to handle the request/response. He then refactors this away from the default to create the custom error handler with handlers for the message and code to be returned. The post ends with the configuration changes to register it with the application and what the result ends up looking like.
