use $session in functions?

[helmut2509]

Hello,

I want to use the $session variable in functions, inside a template. According to the API this variable is available only in templates.

But all values of the $session variable get lost, even when I use 'global $session'.

is there any workaround for this problem?

Like any other ProcessWire variable, the easiest way to access them inside a function is: 

wire('session')

In the function I wrote 

wire('session')->set('number', '12345');

and outside the function I tried :

echo $session->number

...but this variable was empty....

Try to use:

$session->get('number');
or
wire('session')->get('number');

// You can make a test

function setMySession($key = '', $value = '') {
    wire('session')->set($key, $value);
}
setMySession('foo', 'bar');
echo $session->get('foo');

Here is doc page about sessions: https://processwire.com/api/ref/session/

@helmut2509 - it's working fine here. Are you actually calling the function where the "number" session value is set before you try echoing it?
