Making data visible across pages in a multi-page form

Hello,
​
I have a multi-page form which on page 1 asks for selection data, and on page 2 displays the result in a summary table.
​
I want page 3 to display details of a selection from this summary table.
​
However the array data I retrieved in a php action on page 2 is not visible in page 3. I placed the array in a hidden field, so I expect ed that the array would be visible in the page 3 context.
​
Also,I did not see how I could return the data in a var at the end of the php action. I am sure this is covered somewhere in the documentation but I did not find it anywhere.
​
Cheers

Hi Tim,
​
I'm not sure that you can add an array as a value to a hidden input. You could json_encode it to convert it to a string or add the value to the User session and recover it form there.
​
Please see page 34 of the manual for getting values returned from a PHP action.

Hi Bob,
​
I can now retrieve the data I need from the API in Page 2 and store it in a $this->data['result'] array and/or return it as a var from the php action. No worries there, all the data appears in a debugger on Page 2.
​
However, my process is that I then (in page 2) display a summary of the retrieved records to the user and ask them to choose one from this table, so that I can display full information for one record only in Page 3.
​
The problem is that when I get to Page 3, the data retrieved from the API in Page 2 isn't there. The $this->data['result'] field is visible in the debugger but it is empty. The other user entered fields are present, so I can repeat the API query in page 3, but this is not efficient. I tried manipulating the Mix multipage data with global data checkbox, but this made no difference.
​
A related question: I am also unsure as to what syntax I should use in php to access a shortcode, so to do something like:
​

$name = {data:lastname};

Obviously this won't work, but what will? Must it be something like:
​

$name = echo '{data:lastname}';

​
Cheers

To access data in PHP:
​
For {data:variable}

$this->data("variable", "default value if not found");

​
For {var:variable}

$this->get("variable", "default if not found");

This can be found in the shortcodes FAQ, the instructions, and a hundred posts on the forums.

If you want something to be saved to session using multipage, then you need to have a multipage action in the submit event. Then on your summary page you can use multipage with it set to mix with global data. Or you can use a save to session action, and retrieve the value later with {session:variable}

Thank you, and my apologies for missing this. I had read it of course, just slipped past me at the time. Is there a similar syntax for retrieving the {session:variable}?
​
Thanks again for all the help.

Dont think so just use standard PHP syntax.
