Ok, solved it. Thanks for the help and here is the simplified solution for those interested:

Code:

function checkother($elements)
{
   if ($elements[0] == 'radio4')
   {
      if ($elements[1] =='')
         return false;
   }
   return true;
}

registerRule('othercheck','callback','checkother');
addRule(array($questionGroup,'radio_text'),'Please specify other','othercheck');

The actual code is more complicated than this, so I left out the lines that add the radios and textbox. But you can assume that there is one group ($questionGroup) containing just 4 radios. This is added to a required rule. Then there is just one textbox ('radio_text') and the custom rule that you can see above.

No, the other way round: You need a server-side rule, but you *can* also add a custom client-side rule.

You could follow the checkEmail() example on this page:
http://pear.php.net/manual/en/package.html.html-quickform.intro-validation.php

But I'm not sure whether this also works in similar way for group rules.

Another solution would be to use addFormRule(): This allows very customized rules. There is an example available in formrule.php in the docs/examples/ directory.

Putting all the elements inside a group and adding a required rule doesn't work (yes I was silly enough to try that).

Using a group is not wrong here. But you need to define your own (group) rule that checks this special case. You can define both a server- (needed) and a client-side rule. Examples for such custom roles should be availabe in the manual.

Hi.

I'm trying to figure out how to setup the rules for the following:

Lets say I have 4 radios and a textbox. If one of the first 3 radios is filled in then the textbox requires no text. If the forth radio is filled in then the textbox requires some text.

Putting all the elements inside a group and adding a required rule doesn't work (yes I was silly enough to try that).

Any suggestions?

Thanks.
