PHP For Beginners, Ep 39 - Write Your First Middleware

In this episode, we'll discuss the concept of middleware, and how it can be used as a bridge between an incoming request and the core of your application. We'll create two middleware classes to handle route authorization for guests and authenticated users. Watch this full series at phpforbeginners....

Hi Jeffrey, I hope you will see this. First I would like to express my heartfelt gratitude for the priceless contribution you have made to my programming career. I used the PHP for beginners series and I got a distinction in the exams. I once tried Laravel last year on some other channel tutorial but it quickly confused me and I quit. Today, I have completed the Laravel 5.4 series and I am moving to the next Laravel series. Words will never be enough to thank you. You have made more impact than you can even imagine..All the love from Africa, Zimbabwe to be specific.

[@belalehner3937]

This series is getting better and better with every episode. As someone hasn't noticed. JW let You learn the basic logic and techniques behind the very popular Laravel framework. It's very much worth to work with him and write the code (or maybe improve it) by your own, it's for your own benefit... And a short remark on the naming of the series: it's much more advanced than beginner level, but it's not a problem at all!

[@koller18]

Jeffrey, we hope you are doing well and just decided to take a vacation or important business came up. All the best to you, thousands of people are waiting for your return! From Russia with love 💖

[@md.anwarhossain1179]

Dear Jeffrey, This series is really very very helpful. I requested to you please describe about 01. Model and 02. Create a controller NoteController.php Finally, many many thanks for this series ❤

[@RazvanIacob]

I like the longer form videos. Thank you for another good video!

[@Razor2k3]

I am eagerly waiting for the next videos in the series!

[@oheneadjei9832]

Can wait....I’m loving this tutorial from Jeff..

[@MasroorHaider-dk2ch]

Guys more videos are on their website, link is in description

[@jakubfrei3757]

Thx :)

[@thepianist123]

I have seen your tweet on your new phpstorm course on laracast. Now, that must be great. But, we are eagerly waiting for this wonderful php course of yours. So, this is probably high time for you to concentrate on finishing this course again - if possible.

[@hotwings9382]

I hope you didnt give up, i am waiting for the next steps.

[@asheaven1st]

Can't thank enough for this lesson.

[@braintricker_soft]

why i didn't I find this type of content when I learned PHP 6-7 years ago .. Thanks, Jeffery

[@TheRafark]

Where did you learn php 6?

[@braintricker_soft]

@@TheRafark i did not mention php 6 any where i wrote 6-7 years (a period )

[@lserranoit]

It would be awsome, another video with php units tests

[@opionetics]

Awesome series, just wondering if more episodes are coming out or is the end of the series ?

[@thepianist123]

No ChatGPT can deliver a course like this. We need him continue. Let us cheer him up!

[@Фанат-щ9ь]

Wow, my respect, absolutely useful, I have an idea to translate your lessons into my language and we can help a bunch of people to understand php.

[@devgaming4045]

Can we translate this video langauge from English to hindi

[@guisande]

Could the "middleware not found" case, where you throw an Exception, be handled using an Enum? The error would be caught at the editor level (within the language server)

[@jeremyframirezpasapera596]

Hello, if I wanted the controllers to be a class, what would be the best way to do it?

[@pratikbhujel]

Is this the last one ?

[@hilalahmad4736]

Awesome series 👍. Kindly create a video on phpstorm and customization

[@socialoutcast5387]

Hi, Jeffrey it's been over 2 weeks that you haven't uploaded any video in this series please try to be consistent with this series because its my only source of learning programmning and thank you for the great work.

[@alexanderrobinson5570]

Check out Programing with Gio

[@Doomw1ngs]

I'm considering to join your company and start learning about Laravel because I think is powerful tool to do anything. Can I ask you because I saw the "path section" on your site which is amazing btw, if something change on technology and the lectures for example "PHP for beginner " does not working as it used to be, do you update them frequently?

[@whatamiwitnessing1003]

What php version does this series target?

[@patricktrivino4770]

great video! it clearly explains the topic.

[@lahoucineoldakdim7778]

Can you refactor the code to implementing PSR-7 interfaces for HTTP requests and responses.

[@AtomTCP]

finally please implement middleware system in your router

[@olaitanmichaelolanrewaju9122]

I find it hard to use my custom css styling Cus I don't want to use and css frameworks How can i go about that? Thanks for the tutorial

[@PawełJanczak-e6d]

very good series, will it continue?

[@JACKoPL]

This is last free video? Laracast Ep40 for subs...

[@galihanggorojati3455]

Hi Jeffrey, what editor theme you are using?

[@swancompany_inc]

Thanks for the video Jeffery! Had a question about screencasts in general. Have you ever tried recording a down view of your keyboard? So people can see how you work the keyboard and mouse? Wonder if that would add any value or just cause distraction. Just a thought.

[@edewaal97]

I know the software called Camtasia incorporates key presses or shortcut keys. That would be nice to show how he moves between files with his keyboard, or uses it to go to a line in the code for example. I get that's not what this course is about, but these are nice things to know. Maybe something for another series? "How to navigate quickly in phpstorm" But than these videos will come out slower than they already get released. I'm impatiently waiting after every one for the next.

[@eduardogomez4676]

Fantastic video thanks a lot

[@jediampm]

Hi, any news when we will get a new video ???? thanks

[@mpavankumar6695]

what is your editor's font family

[@vincentbeaulieu7553]

What are the advantages of using the key in the route file? Can't I just use `only->(Auth::class)` in the router file directly ? Is it to verify that the middleware exist? can we do that using my technique also? Thanks for these videos !

[@Sunil-kq9bx]

Yes you can do it the way you described. No it is not to verify if the middleware exists. Doing it with a keyword requires the map. Your way would not require to check if the key refers to a class. But you might wanna check if the class being passed to the only method is a middleware. You could make a MiddlewareInterface and have every middleware implement that and cast the parameter from the only method to the MiddlewareInterface. If you than rename $key to $middleware and cast it to be either null or MiddlewareInterface in the resolve method from the Middleware class you could also skip the if check to throw an exception if the middleware is not found (in your case invalid class).

[@jhnsmllr]

@@Sunil-kq9bx Yes better is to create the MiddlewareInterface and simply implement `public function middleware(MiddlewareInterface $middleware): void` Method in the Router.php. Then use it on `routes.php` with `$router->get(...)->middleware(new MyMiddleware())`.

[@teamaccount9320]

Love the lesson

[@socialoutcast5387]

Hi, Jeffrey it's been over 4 months that you haven't uploaded any video in this series please try to be consistent with this series because its my only source of learning programming and thank you for the great work.

[@mexantos]

If there any of your videos explain about hook, event or whatever you call it in the PHP atmosphere, and how to do it just like of this middleware or router on your video, with simple php ways not with frameworks, so we know how it works and got better knowledge about that

[@bulent2435]

nice one. thanks.

[@toanquoc506]

What PHP IDE are you using? thank

[@laracastsofficial]

PHPStorm.

[@amanchaudhary101]

can I get the source code of this project?, that would help me

[@kansermusika2456]

waiting for EPS 40...:

[@howuseehim]

Wow, it's over, after everything...

[@joemart6887]

My spl_autoload_register had an issue finding the files "Core/Middleware/Auth.php" and "Core/Middleware/Guest.php" since I was using the files as Jeffrey did: if($route['middleware'] == "guest") (new Guest)->handle(); if($route['middleware'] == "auth") (new Auth)->handle(); To fix this, I added "Middleware\" before them and it worked! if($route['middleware'] == "guest") (new Middleware\Guest)->handle(); if($route['middleware'] == "auth") (new Middleware\Auth)->handle(); Hopefully this helps someone! You can also add use Core\Middleware\Auth; use Core\Middleware\Guest; at the top! His IDE adds it automatically! It was so confusing!

[@ابوأحمد-ث9ت4ض]

I think this is too advanced for a beginner

[@martinsluters3651]

Thank you for the episode! Would it be correct to say that within Core\Middleware\Middleware class you used static factory pattern to instantiate a concrete middleware?

[@ihorchyshkala6325]

Short answer is 'no'

[@martinsluters3651]

​@@ihorchyshkala6325 thanks. Is it mainly because Core\Middleware\Middleware does not return the instantiated object? A factory should return an object, right?

[@Sunil-kq9bx]

​@@martinsluters3651 correct, it is not a factory because it never returns an object. A factory ussually returns an object, altough it is not common practice there are cases where a factory can return null
