This is the last part in three of the hexagonal pattern series. You can download a simple example [here](].

Presenters allow you to tack on additional fields and logic to an existing Laravel model. There are several libraries out there that assist in creating presenters, namely,

I am going to use robclancy presenter just because I have more experience with it. After we include it in our composer.json and include the two ServiceProviders and we are set to use it.

Laravel is traditionally an MVC framework but MVC just doesn’t seem to scale for larger projects. Typically what ends up happening is logic is crammed into each section: models, views and controllers as the application grows which becomes next to impossible to test. Taylor Otwell’s book mentions the repository pattern but even that doesn’t really solve this scalability problem. After a colleague showed me a blog post about the Hexagonal Pattern in rails, I decided to try the design in Laravel - the results were nice.

Well, I attempted to create a guard/grunt prototype for php. I attempted and failed. Why did I fail? The technology just isn’t there yet. I am going to have to re-think the architecture if I go any further.

I was using pcntl_signal to determine when an application shuts down, so that I could terminate any external processes that had been spawned by guard. One such process event handler was the livereload-protocol I implemented in php which via web sockets notifies any connected clients when files were changed on the server. Similar to how grunt watch works with livereload.

The problem is that pcntl_signal doesn’t work in Windows. Thus, I stopped working on this.

If you’ve ever ventured into javascript land with your Laravel application and suddenly you don’t have a nice <form> to work with but instead are making ajax calls then you might have wondered how to do CSRF protection. Here’s how easy it is to do ajax csrf protection.

headers: {
'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')

So a few months ago, I remember having lunch with Taylor at Genghis Grill and he was talking about maybe doing a video series to make money. Travis and I both suggested he write a book on Laravel. Heck, I even promised that I’d buy, so here we are a few months later and he has his book out. I’ve purchased the book, but haven’t gotten to read it yet.

The IoC container in Laravel is a hidden diamond in the rough that not a lot of people seem to know about. It allows for dependency injection and extremely testable code. However, there was a bug in it so that you could not resolve any class that used optional parameters in it’s constructors (including Eloquent). The bug had been fixed in Laravel 4 which is still not out for beta, so I decided to backport this to Laravel 3 for Taylor (since he’s really busy with L4).
