Menu
I am trying to make a form on my website where users can submit their name and their score will get saved to a list of highscores. (its a quiz game.)
I tried learning to use forms using w3schools. I used this example: https://www.w3schools.com/php/php_forms.asp
<html>
<body>
<form action="welcome.php" method="post">
Name: <input type="text" name="name"><br>
E-mail: <input type="text" name="email"><br>
<input type="submit">
</form>
</body>
</html>
with welcome.php looking like this:
<html>
<body>
Welcome <?php echo $_POST["name"]; ?><br>
Your email address is: <?php echo $_POST["email"]; ?>
</body>
</html>
I literally copy and pasted this example and tried running it and i get this error message:
WelcomeWarning: Undefined array key "name" in [filelocation] on line 4
Your email address is:Warning: Undefined array key "email" in [filelocation] on line 5
However when I replaced all the "post" with "get" it worked. Why? What do I need to do to get it to work with post?
EDIT: Also I left the "post" in the html but i replaced the POST in the welcome.php with REQUEST. It now works, however I think its somehow using GET instead of POSTs because i can see the input in the URL. I definitely need to avoid this. Maybe this helps
Thank you!

you might running directly welcome.php page.
Replace your welcome.php with
<html>
<body>
<?php if ($_SERVER["REQUEST_METHOD"] == "POST") { ?>
Welcome <?php echo $_POST["name"]; ?><br>
Your email address is: <?php echo $_POST["email"]; ?>
<?php }
else{ ?>
<script> location.replace("yourHtmlFileName.html") </script>
<?php } ?>
</body>
</html>
