  1. As mentioned in About us page, I tried sending one bug related email on the given address "help@w3schools.com" but it is not working. Please check if the email account help@w3schools.com needs to updated on the about us page.
  2. I am currently working mongodb and nodejs from w3schools website. I have seen an error in a code. https://www.w3schools.com/nodejs/nodejs_mongodb_create_db.asp In this website there is a code for creating website. : var MongoClient = require('mongodb').MongoClient; var url = "mongodb://localhost:27017/mydb"; MongoClient.connect(url, function(err, db) { if (err) throw err; console.log("Database created!"); db.close(); }); When I run this, I see this on the terminal: (node:26812) DeprecationWarning: current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version. To use the new Server Discover and Monitoring engine, pass option { useUnifiedTopology: true } to the MongoClient constructor. Database created! I needed to change 3rd line. old 3rd line: MongoClient.connect(url, function(err, db) { new 3rd line: MongoClient.connect(url, {useUnifiedTopology: true}, function(err, db) {
  3. Hello everyone, i must do a query that finds all words that finish whit a,e,i,o or u. i' ve used this query but my output in empty . select City from Station where City like '%[aeiou]'; i' ve used the wildcards wrongly?
  4. Hi everyone, i am using mysql for database and when i am trying to run the query SELECT * FROM carshopdatabase i got the following error message: SELECT * FROM carshopdatabase LIMIT 0, 25 So, why is this happening and how do i fix it? Thanks!
  5. I am writing a CRUD and this is a test page to combine 3 separate files into one page. If I comment out the final "else" section entirely the first "if" section and the "else if" section work fine, no errors. After I remove the comment marks for the final "else" section I get this error: PHP Parse error: syntax error, unexpected '?>' in /public_html/crud/test.php on line 139 (<- the line 139 the error points to is the final php closing tag before the closing body tag) It should be obvious, simple, but I can't find any reason why it is throwing out that error and breaking the page (it is just a blank white page). I'm sure somebody can scan through the code and see what I'm missing.

  9. Hello, I donĀ“t know where to post this, then, I'm doing it in here... I'm following the AWESOME HTML 5 tutorial from w3schools.com and I can't get the right answer to one of their exercises about Images (this one: https://www.w3schools.com/html/exercise.asp?filename=exercise_images5). This is my answer: <!DOCTYPE html> <html> <body> <img src="pic_trulli.jpg" style="width:304px;height:228px;"> </body> </html> However, I keep getting an alert telling me that my answer is wrong. Therefore, I'd like to ask if my answer is correct and the system is wrong, or if my answer is wrong. If my answer is wrong, what am I doing wrong? Thanks!
  10. I downloaded a piece of software from github but I can not really get it working, so I would like to get some tips of people who have used this. The name of the script is PHPMailer. I have the latest version. I decided to use gmail for smtp. with autentication. In the troubleshooting they recommended to use composer, but I dont get what / why they want it. What is composer used for? As far as i get it is used to run php commands from a command line. This my script: <?php // Import PHPMailer classes into the global namespace // These must be at the top of your script, not inside a function use PHPMailer\PHPMailer\PHPMailer; use PHPMailer\PHPMailer\Exception; //Load composer's autoloader //require 'vendor/autoload.php'; require 'A:\wamp64\www\PHPMailer\src\Exception.php'; require 'A:\wamp64\www\PHPMailer\src\PHPMailer.php'; require 'A:\wamp64\www\PHPMailer\src\SMTP.php'; $mail = new PHPMailer(true); // Passing `true` enables exceptions try { //Server settings $mail->SMTPDebug = 4; // Enable verbose debug output $mail->isSMTP(); // Set mailer to use SMTP $mail->Host = 'smtp.gmail.com'; // Specify main and backup SMTP servers $mail->SMTPAuth = true; // Enable SMTP authentication $mail->Username = 'my.own.gmail@gmail.com'; // SMTP username $mail->Password = '12345fake'; // SMTP password $mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted $mail->Port = 587; // TCP port to connect to //Recipients $mail->setFrom('my.own.gmail@gmail.com', 'My Own Gmail'); $mail->addAddress('recipient.person999@gmail.com', 'John Doe'); // Add a recipient // $mail->addAddress('ellen@example.com'); // Name is optional // $mail->addReplyTo('info@example.com', 'Information'); // $mail->addCC('cc@example.com'); // $mail->addBCC('bcc@example.com'); //Attachments // $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments // $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name //Content $mail->isHTML(true); // Set email format to HTML $mail->Subject = 'To John Doe (test mail) '; $mail->Body = 'This is the HTML message body <b>in bold!</b>'; $mail->AltBody = 'This is the body in plain text for non-HTML mail clients'; $mail->send(); echo 'Message has been sent'; } catch (Exception $e) { echo 'Message could not be sent.'; echo 'Mailer Error: ' . $mail->ErrorInfo; } ?> when running the script I dont receive an email and I get the following output with a message: 2018-01-05 13:21:25 Connection failed. Error #2: stream_socket_enable_crypto(): SSL operation failed with code 1.

  11. For some reason the W3Schools website is not reachable in IE8. It simply gives a direct HTTP error and I cannot view any page. However the forum works just fine, but that is on a different domain anyway. Why is this? Is this a decision from W3S, to kick browsers that are too old, or is it some browser setting I myself overlooked? Because I find it very weird that W3S, who themselves are teaching how to be cross-browser, are not even compatible at all with this one. I was just trying to figure out whether I should be using the "lightgrey" or "lightgray" colourname, and I know IE8 is the browser that is specific on the difference, but I sadly cannot open this w3schools page about it in that browser because of this, or even any w3s page at all. I'm not necessarily asking for W3S to be compatible with IE8 if this is intended behavior, I know the browser is anciently old and I'm a dinosaur still trying to use it these days, but I just want to know why it is because this is strange. Thanks for your help.
  12. I use W3Schools regularly. I tried using it today 12/1/2016 and was surprised to see the #iframecontainer is NOT working. It works in Chrome. I checked 2 computers on IE10 and am not getting any results. Is anyone else having this issue?
  13. Hi,I am developing my first website template. When I used this script in the internal script, it ran well. But when I added this script inside a file,the jsLint showed that there was almost 20 errors. Here I am sending the screen of the errors. Can you please help me to understand why these errors occurred and how can I resolve these? Here is the script: function openModalSearch() { 'use strict'; var modalSearch = document.getElementById("modal-search-container"); modalSearch.style.height = "100%"; } function closeModalSearch() { 'use strict'; document.getElementById("modal-search-container").style.height = "0%"; } function hideSearch() { 'use strict'; document.getElementById("search-container").style.visibility = "hidden"; } function showSearch(){ 'use strict' document.getElementById("search-container").style.visibility = "visible"; } Thank you in advance......

    Dear all: I have the following php line of code: <?php $var2 = 5; ?> += : <?php $var2 += 4; echo var2; ?><br /> Because of the lack of the dollar sign before var2 following the echo, it spat out the following error: += : Notice: Use of undefined constant var2 - assumed 'var2' in C:xampphtdocsTutorialsPHPw3schoolsintegers.php on line 29var2 My understanding prior to this was that Notice means something bad in the code but it is not an error and would not stop the code from executing. But the code has not executed in this example. Since the code is not executing, I am not seeing the real difference between Notice and other forms of errors that prevent codes from executing. Any clarification please?
  19. Unknown column 'col' in 'field list' Is the error message, i tried all kinds of backticks, and quotes but doesnt work So I was thinking, how can I check (in phpmyadmin or in the mysql console) whether a table has the columns that are needed?

  21. I am attempting to fill a deck of cards data similar to a TCG into a xml file so I can pull the data from it later in Unity using C#. The error I am getting when trying to run it in any web browser is: This page contains the following errors:error on line 6 at column 8: error parsing attribute name Below is a rendering of the page up to the first error. Here is the code starting at line 6: <cardId ="01"> <type name = "Boss"> <title>Gorgona</title> <xp>500 XP</xp> <treasureIcon>Treasure</treasureIcon> <heading>Queen of Medusia</heading> <levelUp>Level Up: Choose a Hero in town. Immediately kill that Hero and place it face-down in your scorekeeping area.</levelUp> </type> </cardId> I've looked over it but can't find what I am missing. If anyone could provide an answer that would be ideal. I am sure its something simple I am missing but I don't see it.
  22. Hey, guys. I'm having trouble with something, and I'm hoping you can help. I'm trying to have it to where you can edit files directly on the website itself. But the problem is, is when I go to edit them, I get an error, and it immediately takes me to my error 403 page that I've set up. So I changed it to permission 777 (and then immediately changed it back afterward, it is now on 644) to see if that was the problem, but I got the same result every time. I was hoping you could take a look at my code, and see if you could tell me what's happening. $edit=$_POST['edit']; $page=$_POST['page']; $file=fopen($page,'w'); if(!mysql_query($file)){ die('Error: '.mysql_error()); } else fwrite($file,$page); Please let me know if you can figure out the problem. And I've also tried removing the 4th 5th and 6th line to see if that was the problem, but still nothing has changed.
  23. Hi, I am having an Issue inputting data into my database with this code. I tested the connection, which works fine, but when I try to submit the form I get the "die("lid query: " . mysql_error());". Any Ideas? <!doctype html> <html> <head> <meta charset="utf-8"> <title>Untitled Document</title> </head> <body> <form action="thispage.php" method="POST"> <input type="text" name="name" placeholder="Check-in Name"> <input type="submit" value='submit'></form> <?php if (isset($_POST['submit'])) { $name = $_POST['name']; $host ="localhost"; $username = "username"; $password = "password"; $dbname = "database"; $con = mysql_connect($host, $username, $password, $dbname); //Check Connection if (!$con) { die("Could not connect: " . mysql_error()); } //Select your database mysql_select_db("database",$con); //Check to make sure the database is there if (!$mysql_select_db) { die ('Can't use the db : ' . mysql_error()); } //Run query $insert = mysql_query("insert into Users(name) values ('$name')"); } //Check Query if (!$insert) { die("lid query: " . mysql_error()); } echo "Data inserted"; mysql_close($con); ?> </body> </html>
  24. Hi good people of w3, I'd been using the tutorials on this site a lot in an attempt to get the email enquiry form working for the website I've been putting together for the place I'm currently employed at. This isn't exactly my forte, I'm pretty decent when it comes to html but php is an animal I'm only just starting to become familiar with.I have an issue currently where particular parts of the form are required to be filled in, and I can successfully generate errors when this does not occur. However, the errors do not actually stop the email from being sent and hence we end up with incomplete enquiries on the other side when the form is not correctly filled in.If anyone could provide some advice as to a means to make the errors stop the email from being sent, that would be much appreciated. The relevant code is below. <?php// define variables and set to empty values$nameErr = $emailErr = $partErr = $phoneErr = "";$name = $email = $part = $comments = $model = $brand = $phone = $contact_method = $product = $breakdown = "";if ($_SERVER["REQUEST_METHOD"] == "POST") { if (empty($_POST["name"])) { $nameErr = "Name is required"; } else { $name = test_input($_POST["name"]); // check if name only contains letters and whitespace if (!preg_match("/^[a-zA-Z ]*$/",$name)) { $nameErr = "Only letters and white space allowed"; } } if (empty($_POST["email"])) { $emailErr = "Email is required"; } else { $email = test_input($_POST["email"]); // check if e-mail address is well-formed if (!filter_var($email, FILTER_VALIDATE_EMAIL)) { $emailErr = "Invalid email format"; } } if (empty($_POST["phone"])) { $contact_methodErr = "Phone number is required"; } else { $phone = test_input($_POST["phone"]); } $contact_method = test_input($_POST["contact_method"]); $brand = test_input($_POST["brand"]); $product = test_input($_POST["product"]); $model = test_input($_POST["model"]); $breakdown = test_input($_POST["breakdown"]); if (empty($_POST["part"])) { $partErr = "Part number or description is required"; } else { $part = test_input($_POST["part"]); } $comments = test_input($_POST["comments"]); } function test_input($data) { $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); return $data;}// Function to validate against any email injection attemptsfunction IsInjected($str){ $injections = array('(n+)', '(r+)', '(t+)', '(%0A+)', '(%0D+)', '(%08+)', '(%09+)' ); $inject = join('|', $injections); $inject = "/$inject/i"; if(preg_match($inject,$str)) { return true; } else { return false; }} //Validate firstif(IsInjected($customer_email)){ echo "Bad email value!"; exit;} $email_from = 'sales@speedyspares.com';//<== update the email address $email_subject = "Online Enquiry"; $email_body = '<html><body>'; $email_body .= '<table rules="all" style="border-color: #666;" cellpadding="10">'; $email_body .= "<tr style='background: #eee;'><td><strong>Name:</strong> </td><td>" . $name = $_POST["name"] .
