Thanks for your help.

Dear emmefisch,
I'm not sure that this is possible, because a revLet is essentially a standalone and data cannot be saved inside standalones.
In the standalone builder, you can set a permission to save data to a user's hard disk. This is probably the easiest way. Just save text from fields and buttons into one or more files on the user's hard disk and access these files the next time when the revLet loads.
Best,

Hi Mark
Thanks for your reply.
No, I want save the cards on the server. There will be thousends of cards and I think it will be better, to load only the 4-5 actual cards in the revlet. I think on database or XML or both. But I am not shure - is it possible to store the whole card seperatly in a file and reload ist after? That would be easyer...

It's possible to go to stacks from a revlet. so you could have your cards in separate stacks on the server, or even assemble them by cgi server side scripting on the fly (not on-rev, as that can't do stacks yet).

Sorry, I am a newbie, how I make this. Thanks.

it's quite simple:
Code: Select all
go invisible stack URL ("http://yourdomain.ch/yourstack.rev")
copy card "templateCard" to stack "the current stack in the revlet"
look here for a tutorial on stack navigation (number 1):

What's on the cards?
If it's primarily text you may find a simple CGI storing text files for them may do what you need.
With images, you can set the fileName of an image object to a URL so you can store those on your server separately from the stack as well.
