$_SESSION['username']/hidden value

Please submit this form to book a project room in the Business School.

I've been trying to print out the $_SESSION['username'] on my form. But nothing gets printed. I've passed the session start(); on all necessary files but it still doesn't work. Please do advise.

I've tried开发者_运维问答 using hidden value also, but it doesn't work. :/

Use session_start(); instead of session start();.

Add var_dump($_SESSION); after the session_start() to your script, for debugging.

Try: echo isset( $_SESSION['username'] ); OR my favourite: print_r( $_SESSION ); and see everything in the session

I got the same problem. The problem exist when you create a variable like

$username

Maybe your $username is empty. I don't know why this is happening.

$username and $_SESSION['username'] are supposed to be not equal or interchangeably.

See the examples below

$_SESSION['token'] will change and be equal to $token if you have $token variable

I tried to copy the same code I have to the other hosting and that works fine. So I conclude that the issue belongs to your hosting.
