  2. In the lesson on PHP Filters in the code sample "Validate an Integer" there is the following code: <?php $int = 100; if (!filter_var($int, FILTER_VALIDATE_INT) === false) { echo("Integer is valid"); } else { echo("Integer is not valid"); } ?> Why use this expression: (!filter_var($int, FILTER_VALIDATE_INT) === false) instead of what seems to me to be the more logical expression?: (filter_var($int, FILTER_VALIDATE_INT) === true) Thanks.
  3. https://www.w3schools.com/php/phptryit.asp?filename=tryphp_filter_adv3 is a tutorial example. It attempts to validate what appears to be a valid URL but claims it is not. I see this forum gets little use, so has the language changed since the example was created, is there a mistake in the example, or is the problem on my end in the browser? I am using the latest FireFox browser under Windows 10.
  4. Hello everybody I recently found this simple Image Hover Effect on w3schools: Image Hover Overlay: https://www.w3schools.com/howto/howto_css_image_overlay.asp This even seems to work on mobile (iOS) devices (touch), as far as I could test in the tryout editor. I then saved the provided code and published it on my own hosting (https://hammermann.ch/test.html). It's still working on desktop, but not on mobile (and I haven't changed any code at all) Any Ideas how to solve that? Thank you and stay healthy! Pascal
  5. Hi The guide on making a scrolling header is great, but it relies on javascript running every time you scroll. That is really expensive (resource-wise) and contributes to a laggy an unresponsive website. I think the guide should be updated to use sticky css-elements instead of js. This method does not have the same performance issues, and I'd argue it's an easier and more elegant solution. The new guide is pretty much already written here. The support for sticky elements is not perfect, so there is a discussion to be had about whether to prioritize browser support or performance, b
  6. When trying to do what the tutorial says in the beginning I come across a problem. The tutorial says the return must be "Hello world", however when you follow the instructions the execute window will close without displaying anything. Perhaps this is something with windows, anyways the tutorial doesn't work because of it as you can't read the output.

  8. Easy tutorial: HTML5 Canvas + pure JavaScript http://slicker.me/fractals/animate.htm
  9. Hello, this is my first post on the forums after learning HTML and JavaScript for the past 2 weeks. I have a suggestion to make for the JavaScript Functions tutorial, specifically learning how to call a function. The tutorial is very good overall and I am enjoying learning about HTML & JavaScript. As this is my first exposure to coding, my suggestion may be out of place or unusual that I did not know this particular information. However, the JavaScript tutorial never to my knowledge taught me how to call a function the way Exercise 1 at the bottom of the Function tutorial (https://www.w3sc
  10. Hello, I have a variable ($post) that contains posted content from database. Now I want to select the first paragraph and insert a code after it (Ads precisely ). Here is my code <?php include "../modules/gfuncs.php"; $topicId=(int)$_GET['id']; #check if topic exists $q=$conn->query("SELECT * FROM topics WHERE id='$topicId'") or die( $conn->error ); if(mysqli_num_rows($q)==0){ header("location: $thisDomain/notfound"); exit; } #check for post $c4p=$conn->query("SELECT * FROM posts WHERE topicid=$topicId") or die($conn->e

  12. Ok so I found out that it is easier to learn from ​video tutorials!. And I tried to figure out how can I fit whole website in a video. ​But the answer is 1interactive video tutorials! Imagine that you have a video and at the beginning you can select what do you want to learn, and select what chapter do you want to start in! For the memory check there can be quizzes in the middle of chapters for example when a code is being typed a quiz pops up that asks us what should I write next to make something happen! I heard that 3/4 people understands better when something is explained in a

  14. Hello there, I am plan (in near future) to start with learning and training with node.js. Since I have habit to learn and remind from w3s (manner of writing), do you plan to add some tutorials and references for node.js? Thank you for all!
  15. I love what w3schools is doing with the SQL tutorial - good stuff. I noticed that one of the most fundamental elements of w3schools (the "Try it now" button) goes missing about half-way through the SQL Tutorial. May I ask why? I teach sql at a local community colleg. I have gone through several textbooks with mixed results, and I am always keeping my eyes open for new ways to teach. I would love to incorporate w3schools SQL tutorial into my class; do you have a db dump available for download of the tables you use? One of my lessons will be having students figuring out how to get the data
  16. I love the work going on at w3Schools - awesome stuff! For the SQL Tutorial, might I suggest a accessible logical model for the tables? For instance, in the "Try it" demo pages, there is a right-hand-side pane with all the available tables, but there is no way to just view the columns of those tables without leaving behind the current sql worksheet. It would be tremendously helpful if users/students could view, via some kind of client-side magic (javascript?), the model of the tables. Ideally, this would include the metadata like primary key and constraint information, but just starting wi
  17. let's say i go through the tutorials from http://www.w3schools.com/Is there a way of knowing when some tutorial has been altered or updated ?Bcz I went through jquery mobile tutorial a year ago and a couple of months later, by accident noticed that there is new stuff in it.
  18. I find this tutorials very useful and I think it will be really handy if you do Bootstrap tutorial. On site getbootstrap.com is nice documentation, but some things aren't explained so well.Who think this is good idea? Thanks.
  19. Using the .NET MVC tutorial, I noticed on http://www.w3schools.com/aspnet/mvc_layout.asp that the first code block needs updated. I believe It should be <!DOCTYPE html><html> <head> <meta charset="utf-8"/> <title>@ViewBag.Title</title> <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" /> <script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")" type="text/javascript"> </script> <script src="@Url.Content("~/Scripts/modernizr-2.5.3.js")"> </script> &l
  20. The last example for window.clearTimeout() method has an explanation that appears to be inconsistent with the 'try it yourself' example on the JavaScript Timing Events page. I have put the text needing corrected in red: How to Stop the Execution?The clearInterval() method is used to stop further executions of the function specified in the setInterval() method. Syntaxwindow.clearInterval(intervalVariable) The window.clearInterval() method can be written without the window prefix. To be able to use the clearInterval() method, you must use a global variable when creating the interval method:
  21. Hello, i'm wondering how to install Apache2 with PHP inside. So far i've downloaded dozens of apache servers and php servers and always getting the the error below. LoadModule php5_module "c:/php/php5apache2.dll" not found (or something very similar) Does certain Apache server version require certain PHP version? I'm pointing out the correct directory and its still telling that its wrong folder. Last time i tried these files.httpd-2.0.65-win32-x86-no_ssl.msiphp-5.3.28-nts-Win32-VC9-x86.msi And received same results. Modified php.ini to point out the extensions folder, added these line

    HTML 5 Games

    Hi, folks. I want to learn to develop HTML games. Could you guys point me some tutorials about this subject? By the way I have a concern: How does one protect the source code? One the games will use javascript and HTML I think that it's not possible. Am I right? Thanks.

  25. Hi all. I am starting a little blog at blogspot.. (any suggestions of who hosts better coding blogs?) Anyway, first up is an example I made detailing some of the caveats of getting started with html5 canvas.

I'm the Steve Carrel type who has a need to be praised. the address ishttp://programahead.blogspot.com the end result can be seen herehttp://respaceable.com/examplemove "usually the people you're worried about stealing your ideas, you should be shoving your ideas down their throats."
