a "Click to convert" addon

I've thought about this as well. It's easy to implement, except that I would need some sort of pop-up or bubble thing. If you could do the research for that, I may be able to implement this sooner.

Clicktips aren't obvious enough. We'd need some special "convert" marker (like for example the External Links module does. The question mark doesn't communicate the ability to convert the currency.

And this project seems more stable: http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/.

Postponing. This will be a feature of the Drupal 6 port only: AHAH forms are super easy there, while they're a complete PITA in Drupal 5.

Won't be implemented in the Drupal 5 version, which is now a bugfix-only branch.

Attached a mini calculator icon that I found at famfamfam silk icons. It could be displayed to the right of the currency symbol, and on mouse over it could display "Click here to convert".

Then, how about a jQuery UI Dialog with buttons and overlay such as the one in this demo.

The dialog could have a currency selection box and invoke Currency API to perform the conversion using Ajax.

Conversion direction would work from the current field currency to a set of enabled currencies that could be selected from widget settings for that field.

Featured added to CVS. Please, check it out. I'll pack it and release as-is if no major issue arises.

Here's the README.txt of the new module:

OVERVIEW
========

Provides 'Click to convert!' addon for Money CCK fields, implemented as an
additional formatter for Money CCK fields.

When enabled, a small calculator icon is displayed next to the money value when
the node is rendered. When the calculator icon is clicked, a conversion dialog
pops up allowing the user to choose the currency to convert the amount to.

The conversion dialog is based on jQuery UI Dialog widget, and can be themed to
suit the site needs. The conversion is performed using the Currency API which
is invoked on the background using Ajax when the user selects a currency.

The module allows site administrators grant access to this feature by means of
the 'use money conversion dialog' permission. When a particular user does not
have permission to use the conversion dialog, the default money formatter is
used.


REQUIREMENTS
============

- CCK (http://drupal.org/project/cck)
- Currency API (http://drupal.org/project/currency)
- Format Number API (http://drupal.org/project/format_number)
- Formatted Number CCK (http://drupal.org/project/formatted_number)
- Money CCK fields (http://drupal.org/project/money)
- jQuery UI (http://drupal.org/project/jquery_ui)


INSTALLATION
============

- Please, make sure all required modules are installed first.

- Copy all contents of this package to your modules directory preserving
  subdirectory structure.

- Goto Administer > Site building > Modules to install this module.

- Goto Administer > User management > Permissions and assign the permission
  'use money conversion dialog' to the user roles of your choice.

- Edit the content types that have Money fields, visit the tab 'Display fields'
  and choose the option 'Conversion dialog' for the Money based fields of your
  choice.

Any chance you could provide a demo for this? Or a quick screen cast?

In any case: AWESOME work! You're pushing this module forward at blazing speeds! Handing over this module to you is the best thing I ever did for it :)

Yep! :-D

Attached a screenshot of the money conversion dialog.

The dark part of the image is becasue the dialog is modal and an overlay darkens the whole HTML document. Still, you can see several money fields with the small calculator icon to the right of them. When you click on one of these icons, the dialog pops up, and you can now convert the amount to any supported currency.

It can all be themed, so the look can be adapted to any site easily. :)

And it goes without affecting the code of the Money CCK field module. It just implements an additional formatter for 'money' fields. So it can be used as an example to write custom addons. Well, I hope.

Great! :)

A next step – but a *very* hard one – would be to implement it in such a manner that a user could convert an entire view to another currency… which would require some serious DB magic. This is something that you'll probably want to postpone because it'll definitely be hard and possibly require some hacks to CCK and/or Views.

Ugh, ma! xD

This is just a little CCK field. Someone in need of such feature would have to write it's own stuff, which would be mostly related to other modules such as Currency API, Views, Computed Field, etc. :-)

Agreed :)

In any case, *excellent* work so far! ;) :)

Sorry, is this Money CCK field Conversion Dialog ready yet? If so, where can i download it? I think I need it and I bet It will be very useful for e-commerce websites
Great work guys!

Hey this is exactly what i am looking for =D Is it included in the latest version of the Money CCK module?
