Five Useful Laravel Blade Directives
May 23, 2018 @ 09:29:53

On the Laravel News site they've shared a list of five useful Blade directives that you may not have known about. Blade is the templating language included with the Laravel framework by default.

We’re going to look at five Laravel Blade directives you can use to simplify your templates, and learn about some convenient directives that make solving specific problems a cinch! If you’re new to the framework, these tips will help you discover the excellent features of Blade, Laravel’s templating engine.

The five on their list provide functionality to:

  1. Check if the user is authenticated
  2. Check if the user is a guest
  3. Include the first view if it exists or includes the second if it doesn’t
  4. Include a view based on a condition
  5. Include a view if it exists

Each one comes with example code showing it in use and a bit of explanation behind its use.

Understanding Design Patterns - Template Method
May 15, 2018 @ 13:07:06

The StarTutorial.com site has continued their series covering common design patterns and their implementation in PHP. In their latest article they cover the Template Method pattern.

[This pattern] defines the skeleton of an algorithm in a method, deferring some steps to subclasses. Template Method lets subclasses redefine certain steps of an algorithm without changing the algorithm’s structure.

In their example, they have two workers that have different schedules but with one difference. Instead of having implementations that differ widely between the two workers (represented by classes) they refactor the main class and allow for a doWork method to be defined in the child. This makes the parent class a sort of "template" for handling the processing with the child filling in the blanks.

Pineco.de:
Lightweight Breadcrumbs in Laravel
Apr 25, 2018 @ 12:10:15

On the Pineco.de site they've posted a tutorial showing how to create a lightweight breadcrumb system for use in a Laravel application. It makes use of a "view composer" to help translate the current path into a matching "crumb".

Breadcrumbs are important in web applications. But most of the time, it’s not the easiest to track the different levels in your URL and generate breadcrumbs from it. Now we give it a try with a simple yet elegant solution.

The post starts by describing the basic concept and the article that inspired their finished product. They needed a dynamic solution that could translate the URL to a breadcrumb list. They created an array with a crumb-to-URL relationship and made use of Laravel's view composer handling to create the collection of crumbs from the current request information. Finally they include the partial view that can be used to render the results, looping through them and outputting each as a link.

CloudWays Blog:
Getting Started With Vue.Js In Symfony
Feb 26, 2018 @ 12:57:04

On the CloudWays blog there's a tutorial posted that walks you through the beginning steps to create a Symfony + Vue.js application with a Symfony 4 application.

As a PHP developer who uses Symfony regularly, I have had a hard time choosing from the numerous JavaScript frontend frameworks available in the market. I had to pick one of the top-rated JavaScript frameworks including Angular, React, Vue and Aurelia.

[...] In this article, I will go through the process of enabling and configuring Vue.js within Symfony applications. Part of this process is covered in the official Symfony documentation.

The tutorial starts by answering the "Why Vue?" question and why frontends are important. He then gets into some of the prerequisites and the steps to create the application:

  • creating the Symfony 4 application via Composer
  • adding a default controller and route
  • making a default Vue.js template via Twig
  • pulling in Vue.js and its requirements via yarn
  • creating the Vue Component

The end result is a simple page that shows the component in a Bootstrap-themed page.

Laravel News:
New Blade Directives Coming to Laravel 5.6
Dec 13, 2017 @ 14:24:12

On the Laravel News site there's a new post sharing some of the new Blade directives coming in the 5.6 version of the Laravel framework.

Laravel 5.6 will include two new form blade directives for cross-site request forgery (CSRF) and HTTP method input, thanks to Taylor Otwell.

The new CSRF handling replaces the previously used format with a simple @csrf tag in the Blade template (inside of the form). The other is related to the method used to submit the form. The new addition allows you to submit the form via something other than POST using the method_field function.

Symfony Finland:
Attaching React.js to a template rendered on the server with Twig
Nov 13, 2017 @ 09:27:49

On the Symfony Finland blog there's a new tutorial posted sharing the results of their effort to get React.js to play nice with Twig, a popular PHP templating library, via a server-side generated template.

React.js is a JavaScript view library that allows developers to create interfaces is a structured way based on a hierarchical component structure. React can either create the DOM structure from scratch, or attach to an existing one rendered by the server to speed up the first load.

If you create Twig templates that match the React rendering, you can take advantage of this feature without a complicated rendering setup.

While there were other methods created to try to solve the problem (rendering the React.js template on the server side) they show a better way via React.js 16 and Twig templates. Code is included showing how to create a simple React application, and how to hook in Twig via a "hydrate" call to pull in the content. React.js has a bit of an issue by default but a little extra work on the Twig side fixes that (see the post for the solution on that one).

Laravel News:
Dynamic templates in Laravel Blade with View::first
Sep 14, 2017 @ 10:54:11

On the Laravel News site there's a tutorial posted showing you how to use Blade's View::first functionality to dynamically show a template if it exists.

When building dynamic components or pages sometimes we want to display a custom template if it exists or otherwise fall back on a default one.

[...] We can solve this problem with a series of conditionals or by using view()->exists() to check if a custom template exists or not, however, Laravel 5.5 brings us a better and more elegant way.

A screencast of the functionality in action is included as well as a text-only version with code samples showing the previously used "if view exists" check and the refactor to use View::first instead.

This dynamic view loading feature was added to Blade in Laravel v5.5 and is a great way of keeping your controllers simple by avoiding extra conditionals when dealing with dynamic templates.

Pawel Mikolajczuk:
Create custom Twig node and parser
Aug 28, 2017 @ 09:16:47

On his Mdeium.com site Pawel Mikolajczuk has written up a post showing you how to create a custom Twig node and parser to extend the powerful functionality already included in this popular PHP templating package.

If You want to create custom twig node then this tutorial is for You. I will show you step by step how to create custom twig syntax (DSL) called gimme (we build it for our Superdesk Publisher project).

He starts with the required changes to your composer.json file to pull Twig in and a sample index.php file to build the Twig instance and add in the new extension (the "gimmie" handling). He then provides the code needed to create the extension based on Twig_Extension for the new node type. Next is an example of the "gimmie" handling in action in a template, dumping out the user information when the article is requested. He explains what each part of the tag is doing and shares the code to create the parser for its contents. Finally he shares the code required to create the "node" class, converting it over to its parsed PHP equivalent.

Introduction to Latte | Best PHP templating engine
Aug 17, 2017 @ 11:30:15

On the Omniceps site there's a new post introducing you to Latte, the templating component of the Nette framework that can be used independently.

A PHP templating engine is the one which gives you ability to write html for your clients efficiently using PHP variables.

However, PHP was originally built to be a templating engine, but yet it was never used primarily as a templating engine. There has been so many PHP templating engine so far in the market since PHP evolved, but none of them has made as great impression on us as Latte. Introducing you to Latte, one of the best PHP templating engine you have come across so far. Also Latte protects your web app from vulnerabilities like XSS (cross site scripting).

The tutorial starts with an example comparing "plain old PHP" templating with the Latte version for a foreach loop. Next they show how to install the Latte component and the two different kinds of macros the tool includes. They also talk about filters, performance concerns, context aware escaping and "pretty output" options.
