You can't submit on sololearn and the 2 notice you get it's because at first the global variable is not set. to hide it you can add this code: $_POST['name'] = (!isset($_POST['name']) || $_POST['name'] == '') ? '' : $_POST['name']; or completely disable the warning

Here I had more time in my hand. I hope it help you understand how it works. ** This is the most basic form you need to validate any data entry if you want to go for somethig bigger. https://code.sololearn.com/w96sehdMmB2P/?ref=app

this is the finished code: <?php echo '<!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <form method="post" action=""> <input type="text" name="name"> <input name="" type="submit"> </form> hi '. $_POST['name'] .'; $_POST['name'] = (!isset($_POST['name']) || $_POST['name'] == '') ? '' : $_POST['name']; </body> </html>'; ?> I tried running it in an app (Dcoder) and gave me this error when submitting.. Uncaught ReferenceError: start is not defined Uncaught ReferenceError: onHasParentDirectory is not defined Uncaught ReferenceError: addRow is not defined Uncaught ReferenceError: addRow is not defined Should I run it in a computer? If you want some detail, I want it to have an input (age) then process the input (do 18-age) and echo the result. Thanks again
