Question about FormitRetriever

I use Formit on a specific page just for a redirect.

In the page being redirected to, I use FormitRetriever to retrieve the values from the previous page.

They appear empty.

Has the fact that I only use formit to redirect any influence on FormitRetriever, e.g. are no variables set by Formit?

You need to set &store=`1` on the FormIt call.

Thanks. It works now. I noticed it is actually documented with the Formit snippet... Maybe a short reference to this in the docs for FormitRetriever as well?

Done. Thanks!

I browsed the FormitRetriever source, just out of curiosity.

I noticed you used the MODx cache manager for storing the values. I also found some interesting documentation of it here: http://rtfm.modx.com/display/revolution20/Caching

Can I compare the MODx cache with the PHP $_SESSION variable as a means for storing temporary results? Or are there pitfalls??

The cache file method is a bit more flexible than storing to $_SESSION, because:

1. You can control exactly how long in seconds the cache file should last before it expires (SESSION goes for the user’s entire browser session).
2. If you have a large amount of data to store, you don’t have to worry about overloading the SESSION data storage mechanism. It just all goes into a file.

In the end, it’s up to you, though, on what method you choose.

Am I correct to presume the cache mechanism is private to a user?

So user A stores $name with value "XYZ" and user B stores $name with "ABC", there will be actually two versions stored in the cache and MODx keeps tracks which version belongs to which user?

No. Cache is done by key, which is universally unique.

How do you pass checkbox values to the FormItRetriever page?

Anyone?...
