[SOLVED] Connection field validation (possibly using CB Auto Action)

[probably for for Kyle]

I need to implement the following feature:

When a frontend user edits the connection tab in his profile and hits the Save button:

• If the selected connection types match a given custom criterion, eg. there should be exacty one non-empty connection type selected, the user's profile is saved
• Else saving is cancelled and the connection tab is re-displayed with a language-dependent warning

What is the best way to achieve this?
I tried with an Auto Action but could not figure out how to cancel a save, nor display a warning.

Thanks in advance.

No trigger is fired during the connection save so there is no way to do this using CB Auto Actions. Options are to edit the comprofiler.php file directly and add validation for the connection type input or use a Joomla system plugin that does some POST variable checks after router has passed you the connections save URL.

Thank you.

I would very much appreciate some guidance, however.

Solution A

Options are to edit the comprofiler.php file directly and add validation for the connection type input.

Which function is best appropriate for this?

Solution B

Use a Joomla system plugin that does some POST variable checks after router has passed you the connections save URL.

I would rather work at the CB level than at the Joomla level. Is it possible to implement this with a CB plugin? If so is there a template plugin I could start from?

I can't help you with core edits, we do not support them. You'll need to review comprofiler.php and make modifications as needed.

Is it possible to implement this with a CB plugin?

No, no trigger fires during the connection save process. A Joomla plugin would be needed so you can act on the form POST URL and redirect back to manage connections with a redirect error message.

What is this???

You DO provide guidance to core edits, eg. in this thread

This is paid support, please provide help. Obviously you can.

What is this???

We do not support core edits. This means I can not help you modify CBs core code unless it's a bug, which this is not. Again, you will need to review comprofiler.php; the functions are rather self explanatory (e.g. saveConnections).

No we do not. That is a bug in CB Auto Actions that I provided a quickfix for.
