[SOLVED] Radio button, if value = "no" don't allow register

Is there a way to have a radio button that show me 2 values "yes" and "no", and if "no" then I can't proceed with registration?

Hmm, as CB uses a function to continue processing even on event of user termination I don't think a redirect action will work in CB Auto Actions. What you'll need to probably do is use CB Auto Actions with a code action with Before Registration trigger and set an error into $_PLUGIN or into $user (e.g. $user->_error = 'FAIL!'). You'll probably want to also condition that radio field based off its post value (e.g. [post_FIELDNAME]).

Could you please help me to set the auto action?

That's what I've done but didn't work:

Type: code

Trigger: onBeforeUserRegistration

User: automatica

Access: all not registered users

Conditional: [cb_checkprivacy] = non acconsento

Method: PHP Eval

Code: $user->_error = 'FAIL!'

Return: echo

Your code isn't going to work like that. It was simply an example. An example to set an error with $_PLUGIN is as follows. Ensure you're testing with debug mode and maximum error reporting enable in Joomla global configuration or you'll never seen any errors in your code if there was one.

Sorry, my role here is to provide guidance and assistance. I cannot provide custom code for each custom requirement.

I've done a little trick without CB Auto Actions and without any hack at the code.

Tell me please if I could have problems in future (next releases, something I could not have considered yet, etc...)

That's what I've done using CB Conditional and CB Subs:

- created 1 radio buttons with 2 values: yes - no
- created field delimeter
- CB Conditional for this delimeter field: show if "no"
- created a text field
- CBSubs hide this field at registration
- CB Conditional set this text field as requested if "no"

I've tested it and if I set the radio field "no" it correctly show me the field delimiter message and don't show the text field that now is set as required; but user cannot type anything into that text field 'cause CBSubs hide it at registration so if I click on the register button I can't proceed till I don't set "yes".

Could I encounter problems in future with this trick?

That seams like it should work fine. No idea if it'd cause future problems, but can't see any reason why it should.
