Retrieve session data after save to session action

Hello,
​
I found another topic similar, but the solution in that topic didn't work for me.
​
I set up 2 forms.
​
In form 1 I collect some data then in the submit event I do a "save to session" action and redirect to Form 2. The name of this action is "save_to_session17".
​
In form 2, based on the reply in the earlier topic, I place php code
​

\GApp::session()->get("save_to_session17.var", "default");

$this->data['var'] = $this->get("save_to_session17","default");

return $this->data['var'];

before the display_section action and then a debugger which shows:
​
​

Array
(
    [option] => com_chronoforms6
    [chronoform] => test2
    [_ga] => GA1.2.1332169317.1437286808
    [c0b3da5e2c719fc1d8c4287f74bf65ff] => 3sldcvmijuqkr5g79urlaqquc5
    [69acbdca18c366bd0fda2fd3c2f798f1] => gp248pj9lgru6thqnmtlthbe86
    [Itemid] => 
    [var] => default
)

Array
(
    [php4] => Array
        (
            [returned] => default
            [var] => default
        )

)

So obviously it isn't getting the session data returned in the second form, but I can't see what I have done wrong.
​
Hope someone can help here..
​
Cheers

Sorry, I should also say there is a redirect which calls Form 2 from the Form 1 submit event.

{session:variable}

Hi,
​
Thank you - I was certainly seeing it as more complicated than it is. Now I can see the session data, but I am having trouble getting it decoded.
​
The string returned is json so i tried to json_decode it, but it didn't return anything. I tried a json parser which gave it the OK.
​
So then I simply copy/pasted the string and hard coded it as a test, and it decoded perfectly.
​
The php code is this:
​

$this->data['sess'] = '{session:save_to_session17}';
$this->data['sess_decode'] = json_decode($this->data['sess'], true);

$this->data['test'] = '{"option":"com_chronoforms6","chronoform":"test","event":"submit","firstname":"Tim","lastname":"S","calendar5":"2018-07-16 00:00:00","AI":"","button2":"","_ga":"GA1.2.1332169317.1437286808","c0b3da5e2c719fc1d8c4287f74bf65ff":"3sldcvmijuqkr5g79urlaqquc5","69acbdca18c366bd0fda2fd3c2f798f1":"gp248pj9lgru6thqnmtlthbe86","Itemid":null}';
$this->data['test2'] = json_decode($this->data['test'], true);

and the debug returns this:
​

            [Itemid] => 
        )

)

As far as I can see the hard coded string is identical to the session data (I copy/pasted it) so I don't know why it would behave differently for the two scenarios.
​
Thanks for all your patience and help.

{session/jsonde:variable}

Hi,
​
Thanks again... but no luck I'm afraid.
​
Changed that shortcode to
​

$this->data['sess'] = '{session/jsonde:save_to_session17}';

and got no result back from the shortcode. So then tried:
​

$this->data['sess'] = '{session/json_de:save_to_session17}';

and it was the same as without the /json_de :

I also tried:

$this->data['sess'] = '{session/json_decode:save_to_session17}';

and got the same as above.

Sorry, it's {session.jsonde:variable}

Hmmm
​
Not having much luck here.
​

$this->data['sess'] = '{session.jsonde:save_to_session17}';

returned nothing.
​

$this->data['sess'] = '{session.json_de:save_to_session17}';

returned the string but did not allow me to decode it (just as if it wasn't there).
​
Cheers

Right well since you're doing this in PHP why not just use json_decode() ?

If you see a few posts ago, #379059 I tried that but it would not decode the returned string for some reason and just returned nothing.
But when I copy/pasted the string and assigned it to a php variable, it decoded fine.

I am in fact trying to upgrade these working forms from V5 to V6. I could always leave them alone, but I'd prefer to have everything in V6.

Cheers

Well you can't use shortcode in PHP in V6.

OK... well I have always used PHP for this kind of thing, so what is the preferred approach in V6?
​
I am happy to change my ways.
​
All I need is some functionality that is the equivalent of "Session to Data" in V5.
​
Cheers

well how exactly are you wanting to use the session variable? What's the end goal for the data?

It is a specialised payment gateway situation.
​
The client enters some data in a form then I redirect them off to another form that manages the payment gateway functions. I have several different forms that need the payment gateway so the gateway form is a sort of function and has no display data. When the gateway process has concluded it redirects to an event in the calling form, to complete the process. It isn't really a shop, since the calling forms are quite specialised for the business we conduct.
​
So I want to restore the original session data on return from the gateway.
​
Another possible strategy would be a temporary data save to a table in the calling form, reading it back in the event after the gateway function.
​
Most of my V6 conversion has gone well.
​
Cheers

Use a multi page action. There's a demo form showing you how to use it.
