    There was one thing in this lesson that I think might confuse people just starting out. It isn't normal to link directly to an include file from a form like this. The include file will not contain any of the HTML from the view (index.php in this case) and so when you submit your form the output will be missing things like your title, styles or other controls and content you have on the page. So instead what we do is link the form back to the view and add a conditional statement in index.php that reads if(isset($_POST['submit'])) include('includes/calc.inc.php'); This includes the calculator into the current view but only when the form has been submitted. Anyway, great video. Great series. There's always more to learn.

      @@hearvie The point is, after user submit the form, all provided data goes to calc.inc.php using POST method. In this situation we are leaving calculator form forever :P because after calculation is done, the result is gonna be seen in calc.inc.php page after using echo. I understand that Dani did it just to show some practice example how to use classes, methods and properties but in real app, we should send the result back to form page and show it to the user. But now I think that @phyternl explained it much better than me so sorry if I confused you.

    In my opinion, Calc should be renamed as Calculator. And the method calculator should be renamed as calculate. It is as per the "nice to have" convention that class should be named as Noun since it represents an object/thing and method should be named as a Verb since it represents an action that an object performs.

    May i rant a little bit about the Tutorial? Hope people wont hate me.
    In PHP we have PSR standards, if you follow PSR-4 Autoloading you can easily implement external libraries within your code, so rather creating a file with .class i would follow the standard. You could use PSR-0 even it is deprecated.
    In your calc.inc.php you have a closing php Tag, according to the PSR-2, the closing tag tag MUST be omitted from files containing only PHP.
    You class i would rather call "Calculator" and the Method i would call "calculate" instead of switch case i would create private methods and use call_user_func_array to call the methods with a method_exists check before.
    Following defined standards is a good thing in my opinion, since all the Frameworks and Companies out there are following them, so if you know them early, it will be easier for you to work in a company/team.

      Completely agree with your points about defined standards. Using call_user_func_array instead of switch is a matter of didactics, I personally wouldn't use that in this video, it's just a bridge too far for most people. I have to say that I find the use of an include file inside an action tag very peculiar, though.

    If you run this under Linux, make sure your class names (e.g., Calc) and file names (e.g., Calc.inc.php) use same cases. In this example, calc.inc.php won't work, as Unix-based systems are case-sensitive by default.

    Hi, Dani. Thank you a lot for your video. I hope you still answer questions on the topic.
    Towards the end of the video you said that the correct design pattern is to split class, execution and presentation code.
    I want to place the result so that the calculator can be used again immediately without the need of going back.
    Without AJAX, i must place the execution of the class in the presentation file, correct?
    Is it better to place the result in a $_SESSION global, redirect and then pull the result in the index page?

    I am new in terms of learning PHP. I learned Javascript before PHP, so I am sorry if this question makes no sense. Why do we need to post those data to another PHP page? Can it be done on the same page? The benefit to posting those data to another PHP is that our code looks cleaner? And if we posted those data on another PHP page, how can we use it on the index page? Do we have to use the session, return to the index page and access that particular value via session?

    • @Dani_Krossing
      @Dani_Krossing  2 роки тому +1

      We send the data to another script file for a couple of reasons. 🙂 By doing so we make sure that the PHP code isn't run, unless the user actively triggers the need for it.
      Keeping PHP code in our HTML files (for example the index page), is only meant for code that is needed on that specific page. Like for example if we need PHP to write error messages on that page. And even then, I would personally just create a class named ErrorMessages, and have methods in there which can print various types of error messages, in case I need to use them multiple times.
      By splitting code into separate files, we also ensure that our HTML files don't become overly long or complex, which will both cause extra load times and cluttering in our files. This is one of the benefits of using classes, or even functions.
      And to answer your question, any data that needs to generally be accessible on your entire website, you store in the session for easy access. Let's say the users "username" for example, we don't want to fetch from the database EVERY time we need it, since it causes extra unnecessary load times.

    I spent 2 hours troubleshooting the issue where it differs that you are using a case-insensitive OS. Can we recommend your next lessons be performed on a more industry standard OS? like Linux? Macos? None of the companies my friend are getting hired for are using windows os. Its frustrating when I think its your autoloader, but instead its a conflict caused by you capitalizing the class name. I apologize for the frustrated tone, your classes have been invaluable in learning OOP - Ive been learning how to debug, and getting in some good debug exp, which is definitely a required skill!

    • @Dani_Krossing
      @Dani_Krossing  3 роки тому

      Do you have any documentation to prove that PHP classes and functions are different on different OS? 🙂
      I know that some path naming might be different on different OS, but it seems very odd to me that the coding language itself changes.
      Would love to know if that’s the case. 🙂 But to answer the question, no I won’t be teaching the different variants if you are right about the OS, since I don’t have a Mac or Linux to test it out on. But honestly… in my 7 years I haven’t heard about the issue you are describing 😅

      After placing echo all over the place in class-autoload.inc.php and directly including class-autoload.inc.php in calc.inc.php i was able to witness the autoloader’s mistake. I changed the class and its references in all files to “calc” and everything worked flawlessly. This worked for me, added right after the $className variable was assigned within the function myAutoLoader:
      function myAutoLoader ($className) {
      strtolower ($className);
      $url = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

    • @Dani_Krossing
      @Dani_Krossing  3 роки тому

      No problem 🙂 Well, from glancing your code it seems your code isn’t like I taught in my “auto load tutorial”.
      In your code, you included a “strtolower()”, which is why your code can’t find the class in your autoload function, because you tell it to search for a lowercase class name. 🙂
      So it isn’t a OS issue from what I can see, which seemed odd to me when you told me about it hehe.
      It is common practice to name your classes with a uppercase letter, so if I were you I would change my class name back and make sure your autoload looks like the one I showed in my tutorial. 🙂

      @@Dani_Krossing i think you misunderstand; the added line is the final fix to the issue I was having. I did other things to show the case-sensitive issue, the strtolower() was the catch-all final fix to make the issue compatible cross-platform. Looking through the other comments, shows the issue isnt isolated to me. I eventually changed my class name(s) back to beginning with cap letter. But again, it wont work unless the strtolower() is in place. Glad to contribute however. When you update the videos, consider the diversity of our differing environments?

    Very nice tutorial up to now. I like your style and pacing a lot. It's just... you do use some peculiar or old-fashioned conventions, it's best to stick to PSR in my opinion. However, there's one thing that left me a bit flabberghasted and that's the include file which you put in the form action. That's as weird as prime beef in a sausage. I understand that you want to promote separation of concerns, but why not make a copy of index.php, ditch the form and put everything from calc.inc.php in there? Or just include calc.inc.php if you really want to use an include? Anyway, that't up till now my only peeve, the rest of the course gets an 11 out of 10.

This means that the entirety of PHP logic is resolved on the server. So, unless you use JavaScript to make the calculation inside the browser (and handle the DOM changes) you need to send a request back to the server so that PHP can spring into action.
    Essentially, calc.inc.php is another HTML page that the server computes and sends back to the client upon submitting the form.
    The calculation itself could have been resolved with a calculator function from inside calc.inc.php but having it as a class method serves two purposes. 1. It detaches the logic to a separate file, making it reusable; 2. it makes its context easier to read and understand.

      There are a couple of reasons for why we send the data to a separate file. 🙂 I can see how in this particular project you might not see the benefits, since it is just a VERY basic example. But later on once you start getting a bit more into security, and need to learn how to properly handle user submitted data, then you will be glad that you learned how to do it "the correct way".
      But here are a few reasons for why you shouldn't create all PHP on the same page:
      1.
      At some point you will start to have A LOT of PHP inside your website, and having it ALL inside your main pages is extremely cluttered. So separating the tasks into different files is considered best practice. You should ONLY keep PHP on your web pages, that are absolutely necessary.
      2.
      When it comes to user submissions through an input, we want to have the data sanitized and most likely run a handful of error handlers, to check that the data was properly submitted. Which is a lot easier to do in a separate script.
      3.
      When you submit data using a post or get method, we want to make sure that we DON'T run the following PHP script, unless it was submitted correctly, which is also easier using separate pages.
      Just to name a few. 🙂

    I'm watching your series to learn OOP in PHP (I've been using OOP in other languages for ages and I've been using PHP for ages, just never OOP PHP) and the videos are great for this purpose. But if I try to imagine a person who is also learning OOP from these videos, I think he could get really confused now. Because this must be the worst example of a practical use of a class I've ever seen :-) Why would you store the two numbers and the operator in class properties using the constructor, just to be able to call a method to do some calculation on them and then never use them again? I would probably ask - oh wait, couldn't you just make a function compute(int $a, int $b, string $operator)? Please don't take me wrong, I think you are a great teacher and your videos taught me a lot in a short time. But I think that even a negative feedback can be usefull ;-)

    Hi @mmtuts
    Why you use in class-autoload.inc.php
    if(strpos($url, 'includes') !== false){
    not
    if(strpos($url, 'includes') == true){ // Maybe it's better to understand it how it works .
    And when we talking about OOP maybe it's better way to create function for check $url ?
    Like this:
    function currentUrl() {
    $host = $_SERVER['HTTP_HOST'];
    $script = $_SERVER['REQUEST_URI'];
    return $host . $script ;
    }
    And when we want add something we just change the function.
    I would know what you think about it

      if(strpos($url, 'includes') == true) this statement is wrong, it works because php can convert any number to true. the strpos function returns either false or a number, so it is correct to ask if the result is not false.

    Why wouldn't you just use procedural "if" statements to handle what to do with the posted numbers? This seems like Ironically more work.
