@@nelsonke6840 It's simple! Learn one new thing every day, and by day 365 you will have learned 365 new things. 🙂 Learn two new things a day, and you'll know twice that. That's the simple rule I go by, to not let new knowledge overwhelm or demotivate me. ☺ One step at a time, and eventually you'll reach your destination.

What a great tutorial. At first well explained, super easy and good to follow because at the right pace. Compared to your two previous login systems in PHP, this one is even better, don't get me wrong, your previous tutorials also been great. With that said, I can't await part 2 coming out, and please keep up the good work. Have a great day, Daniel.

Great job and amazing tutorial! If you are thinking about a login system next i would love one that uses a role on the sessions in order to unlock some content of the webiste if you are a admin, a normal user etc. Keep it up!

[@chriseski]

What an amazing tutorial Dani! I really appreciate the fact that you explain even the simplest thing over and over again, using almost the same words every time, as if you try to explain something simple to a child. Nothing is taken for granted even after having explained something 2 or 3 times already, or even in a previous video of the series. Repetition is what makes something concrete in our brains, and you do this the best way possible IMO! Thank you very much! 👌💪

great video! I was surprised by how much you have thought about implementing a robust system. This is easily production ready code. Thank you for teaching :)

[@Dani_Krossing]

Thank you. ☺ It is not production ready code though. 🙂 There are much missing in terms of error handling, and hack prevention. But it's a good video for learning the basics .

[@hindihits9260]

@@Dani_Krossing at least it's better than what I have found in other tutorials.

[@ArtOlson2008]

I've learned alot from this video, but I think it is unnecessarily advanced in the way it builds up all of the security, errors, exceptions and supporting files. While these are all implementations a beginner may come across this is hardly accessible to a beginner when the most basic functional password validation is nested in 7 supporting files.

[@GerritforBazeja]

Love you! Nice to learn the saver way of data handling from you! Question: * Why not repaet password as you did in the earlier course? * can you show how to do it with the radio_button?!

[@techyjc]

Another great video, just an observation might be worth mentioning filter_var($email, FILTER_VALIDATE_EMAIL, FILTER_FLAG_EMAIL_UNICODE) as it supports email addresses with characters from other languages. Otherwise some addresses with foreign language characters would return false.

[@dconnectzone]

It was so helpful! I'm creating admin panel for my project. It would be nice if you made video about using volley php and creating profile picture setup. Or at least video on php creating profile picture setup. I'm trying to create android app and inside fragment_userprofile I wanted to let user set picture for profile but getting stuck as It was my first time doing volley php project.

[@felixkuluchumila5262]

I'm gonna watch this video ten times , its so important, i gotta master all these!

[@regimatic]

@regimatic 0 seconds ago I watched this twice. I think you went from crawling to running without learning how to walk. I watched and performed all the previous 27 lessons. This is over my head. You got into object oriented programming (I guess): arrays within PDOs, methods, sessions, try-catch, MBC-model, etc. I think I needed another 10 lessons to truly understand this. To use this on a project, I'd have to paste your code and pray... because I couldn't duplicate a custom effort. I wish you would have just showed us how to do it as procedures. I though I learned something with lesson 1-27 (and I did), but now think I need something in between lesson 27 and lesson 37. I TRUELY like our training, but am lost here.

[@yousifky]

❤❤❤❤

[@Sweetcommando]

Just a heads up, if anyone has any errors along the way, it is 99% a simple typo. I spent almost an hour trying to figure out why the error handlers don't work and its because I wrote config.session.inc.php instead of config_session.inc.php lmao

[@LokaiOFF]

Hey i have built website with your login system, and its amazing, not this one, i have watched the one that is a year older but still amazing work, but could you do forgotten password recovery in OOP PDO PHP kind of stuff? I tried to find something on the internet and theres nothing, because you know i think o lot of people have built a login system based on that video, and video you have on your profile doesnt seem to continue on the logic you have implemented in that year old one, so i would really apreciate it! :D

[@skillz3501]

Can you do a 2023 update for a login system and forgot password? Love your vids btw really helpful. Thanks

[@samstephens3946]

Hi all, 👋 I know it's probably beyond the scope of this tutorial but is anyone having issues with the "check_signup_errors()" when using Safari. It all works perfectly in Chrome etc etc but the _SESSION isn't returning the error data to the index.php page when using Safari it only returns the 'last_regeneration' when var_dump'd/print_r'd. As I say all works perfectly in Chrome just wondered if anyone had similar issues when using Safari. (and maybe a cheeky link for a solution 😁) Many thanks for the Tutorials Playlist Dani a lot of effort must have gone into making this.

[@taylorchou9812]

i can't show error message in any browser, I am still trying to find where I did wrong...

[@ckh8217]

I think you can skip the bindParam and put an associative array in the execute, like so: $stmt->execute([':username' => $username]);

[@Dani_Krossing]

Yes you can. 🙂 But it comes with some “drawbacks” as well. Or rather “features you can’t do”. But in this example here either way is perfectly fine.

[@CoderzF1]

lol.... im at time stamp 24:42 and already see some refactoring that i would personally do. Just a habit of mine from coding in kotlin and java for a few years now.

[@CoderzF1]

also, meant no disrespect. Just the code organizer in me would have arranged those if statements in a different manner. you're good at what you do.

[@Dani_Krossing]

@@CoderzF1Personally I had just used a exit() function and not used a else statement. 🙂 But when recording at the same time, the brain unfortunately oversees that type of details hehe.

[@rolandlawrence2654]

Dani, I agree with all the people stating about your teaching abilities. I saw your last message which stated about you getting a job and going to work. That is definitely our loss. I do have one question which I hope you can answer for me. Since I am working with WordPress, I cannot use index.php. What would you recommend I use instead? I definitely appreciate your feedback. Thanks.

[@Dani_Krossing]

Thanks for the kind words 😊 If you are referring to creating a login system, then it is very important to point out that the one I teach in this video, is not a production ready login system. It is simply a lesson to get people used to using PHP. 🙂 If you use Wordpress, then I recommend investing in a up-to-date login system plugin. Other solutions that are typically used IRL, is a framework like Laravel, since it has security build into it. My point is, that creating something as important as a login system, which requires TOP NOTCH security, should not be build from ground up… unless you are an expert in PHP security. Most professionals use frameworks and other tools, since features like this already exist, which are better than anything we can make ourselves. 🙂

It says I am logged in successfully, but I'm not getting error returned if I leave out something, and it is not returning the :"logged in as" when I successfully log in.

Is there any way you could show us how to actually host our websites, and what to change in e.g. this sign-up system code such that it is compatible for when the website is not being hosted locally anymore?

[@Dani_Krossing]

All you gotta do, is log into your dashboard on your hosting companys website, and in there it will have a link to your database. 🙂 In most cases hosting companies provide a MySQL database identical to the phpmyadmin we used in this lesson here. You will also find the database information in the dashboard, which tells you the information you need to replace inside the dbh.inc.php file. Then all you gotta do is either create the tables inside the online database, or export the one from your local project, and import it into your online version. I can't give you a specific tutorial, since all hosting companies have a different dashboard interface. So if you can't find the database link once logged in, then my best advice is for you to contact them and ask where it is. 🙂

in the "check_signup_errors()" function where you check for "isset($_SESSION["error_signup"])" add this: unset($_SESSION["signup_data"]); -------------------------------------------------------- simpty you clear off the session variable that holds the old data after you use it in the view.

For whatever reason, whenever I tried to add a new user and some bad data, it worked - throwing an error. Then i would add a new user with good data - it would spit out my success message BUT it would retain the old BAD data in the inputs... So i added an unset($_SESSSION) to rid the data after a successful signup.... I was wondering if that was a good thing or right thing to do.?

[@realdaly]

Same thing happened to me and I added the "unset" if there was an unsuccessfull signup instead, meaning right after I clear off the "error_signup" session variable, idk it just makes more sense for me that way.

I spend quite a bit of time explaining it in the video I believe? 🙂 The .inc is just a naming convention. It doesn’t “do anything”, besides letting us know that it is a file, that is only meant to run a PHP script. Meaning it doesn’t have any HTML, and is not a page that is shown to the user inside the browser.
