Any way to add Terms and Conditions to a pdf page

[JAY MAC]

What I would like to do is have a Terms and Conditions page that will only reveal the body of the pdf if the user accepts the terms and conditions.

If that isnt possible could I possibly send 2 pdf's one is a terms page that when accepted reveals a password to open the second password protected pdf?

Thanks in advance for the help!

Is it only going to be downloaded from a web site?

If so, I'd do that with the web page. Make them agree to terms before downloading the PDF.

It depends on how secure it needs to be. For example, you could use JavaScript to control the visiblity of content (using layers, aka OCGs), but this cannot be considered secure. It may be sufficient though, considering your willingness to give out a password, which would also work.

For that latter, you could set up a button with the following JavaScript as the Mouse Up action:




var resp = app.alert("Do you accept the terms and conditions?", 2, 2);

// If the user clicked Yes...
if (resp === 4) {
app.alert("The password is: ABC-123", 3);
} else {
app.alert("Scram!", 1);
}

Thanks for the posts guys.

I came up with a workaround by making the terms page the PDF which has security to password protect attachments. I then attached the PDF file with the content. When the user clicks the I Agree button in the Terms PDF I have an action to make the password for the attachment visible.

Thanks again for the info though ill jot that down.

OK the workaround with securing the attachment works but its kinda clunky so I am trying out Georges suggestion with using layers. I brought in a solid colored layer to go over top of the content and what I want to do is after they accept the Terms the solid layer becomes invisible.

The problem I have now is that when I try to add a Set Layer Visibility action to a Mouse Up part of a button I get the error "The target layer states of the selected actions will be set to the current state."

Maybe i have to use javascript on the button instead?

Thanks in advance for your help!

Here's some good information on controlling layers via javaScript: <http://www.acrobatusers.com/tech_corners/javascript_corner/tips/2006/create_use_layers/>

I looked at that page and tried to copy paste the line

var ocg = FindOCG(aLayers[this.inc]);
ocg.state = !ocg.state;

to my button Mouse Up action and modifying it with

var ocg = FindOCG("Cover");
ocg.state = !ocg.state;

That didnt work but im sure im doing something wrong.

You need to read and understand the article. The FindOCG is a custom function that's intended to be placed in a document-level JavaScript. But for testing purposes you can place the function definition (the first bit of code presented in that article), just before the code you're using.

Ah ok ill give that a shot. Sorry for the ignorance, coding makes my head spin.

I found exactly what I wanted to do but using InDesign exported layers and the Set Layer Visibility action.

Here it is if anyone is interested <http://www.layersmagazine.com/acrobat-9-adding-layers-to-pdf-documents.html>

I wish I had the time to delve into coding but just dont have the time or patience.

Thanks to all for the help.
