PHP Session not started but ignored if started

[Joveice]

Hi, I'm trying to use my function but it returns null each time there is something wrong and I know it does it on this line

if (!empty($_SESSION['errormsg'])) {
	return('null');
}

Tho I know it's not empty because I have it echo the error message in the corner while working.

If I add session_start(); on the start of the function script file this error comes up (and still returns null).

line 14 is session_start();

Notice: A session had already been started - ignoring session_start() in *File* on line 14

What is this? and how do you fix this?

you're asking if errormsg is not empty then return null. Thus if it has a value it will return. take the ! away then it will return null if empty.

O snap, Thanks!

I hope I can learn more about PHP from a school one day and not just by watching youtube videos and browsing the documentation

YouTube and documents are vastly better than education. Here in the UK they still teach visual basic as a programming language.
