I'm trying to follow
this manual
And here are my validation fields
Sub-question validation equation:
Code:
(is_empty(address_postcode) or regexMatch ('/\b\y\d{2}-\d{3}\b/', address_postcode))
and
(is_empty(address_post)or regexMatch ('/[a-zA-Z0-9]/', address_post))
Sub-question validation tip:
Code:
{if((is_empty(address_postcode) or regexMatch ('/\b\d{2}-\d{3}\b/', address_postcode)),'', 'Postcode is XX-XXX. i.e. 11-995<br />')}
{if((is_empty(address_post)or regexMatch ('/[a-zA-Z0-9]/', address_post)),'', 'Type a proper post name.')}
But it doesn't let me go through. What am I doing wrong?
"Whole question validation equation" like in the subject or "Sub-question validation equation" like in your post?
I would test sections of the equation before putting all parts together.
It could be that you're doing everything correct but LimeSurvey has a bug.
So what version/build of LimeSurvey is used?
The latest, jelo. Installed today.
The subject refers to the tutorial/manual's name in the link provided but I am using multiple short text with three sub-questions where two of them are validated by regex
You will have to post the version/build. There are different branches and if everybody post today the search function will be useless if you search for certain versions.
You should export a survey with your question with issues. I don't know which place the validation equation is put. That's why I asked about the whole question vs. sub-question validation wording in your post.
Use the question validation field instead of the subquestion validation.
I'm currently out of time but please try to change the AND into a OR and check if that helps.
Put that into the question validation (advanced settings of question)
Code:
(is_empty(address_postcode) or regexMatch ('/\b\y\d{2}-\d{3}\b/', address_postcode))
or
(is_empty(address_post)or regexMatch ('/[a-zA-Z0-9]/', address_post))
There are RegEx bugs in LimeSurvey popping up from time to time where certain rules are not working correctly. Sometimes everything is done correctly but LS is buggy.
If LS seems buggy : the best is to make a bug report

I used this feature in the old LimeSurvey 2.2x and it worked like a charm.
