Would it be possible for an "IfCookie" syntax, similar to "IfTags", which allows the ability to check the cookie value outside of a module?

My use case is that I am including a signature in a forum by using this code for each post:

[[include signature:%%created_by%%]]

(The error message for if the page doesn't exist is hidden with CSS)

An "IfCookie" syntax would allow me to do something like this:

[[ifcookie show-signature="yes"]]
[[include signature:%%created_by%%]]
[[/ifcookie]]

[[ifcookie show-signature="no"]]
[[collapsible show="click here to show the signature (auto hidden)" hide="hide signature"]]
[[include signature:%%created_by%%]]
[[/collapsible]]
[[/ifcookie]]

Two questions for Gabrys (or anyone else on the development team):

1. Is this easy/hard to implement?
2. Can you see any design flaws/areas for improvement in this idea?

Answering just your use-case:-

Because cookies are per-browser and not per-user, this would not work.

• If two people shared a PC and one had a signature and the other didn't.
• If one person uses two browsers
• If the cookie was not set, neither paragraph would be displayed
• The existence of the page is independent of the cookie — That's asking for trouble.

I believe modules inside ListPages will be here before too long?

[[module css]]
.yes-para {display:none;}
[[/module]]

[[module ListPages page="signature:%%created_by%%"]]
  [[module css]]
  .yes-para {display:inherit;}
  .no-para {display:none;}
  [[/module]]
[[/module]]

[[div class="yes-para"]]
[[include signature:%%created_by%%]]
[[/div]]

[[div class="no-para"]]
[[collapsible show="click here to show the signature (auto hidden)" hide="hide signature"]]
[[include signature:%%created_by%%]]
[[/collapsible]]
[[/div]]

(It would work with an include inside ListPages, but it's more obvious written this way.)

I haven't yet seen a good use-case for cookies that global variables were not a better solution for. They're a cool idea, but I can not think what I, or anyone else, would use them for.

If I understand your code correctly… you're writing down a way to detect if someone has created a signature, and to show it if they have? My use case was to allow a single user to determine if he sees those signatures or not (or with cookies, to allow a certain browser to tell the website whether or not to show signatures… which although not perfect is better than having no user control at all)

Fair enough, but if the cookie was not set, neither paragraph would be displayed. That's actually a fairly important bug, since I think a random new anonymous user wont have the cookie set?
