Hi Team,

I have a question date format i want to add with the calendar or dropdown boxes another text field (to put some description). i can ? if yes how ?
If no, if i create a question with Multiple short text, i can validate only one field for the date format and the other field (text) for the description ?

Thanks

Why not use two questions?

I want them in the same question, because we can have the description then the date or the opposite; and in the case of two question it will have a switch between previous and next

Run the survey in group-by-group mode and place both questions in the same group.

I have a long questionnaire and a lot of conditions to show or hide some questions, and it's a hard work to do for each question a group, my only solution and one of the two mentioned above, if it's possible.

Thanks

tpartner any news please

Hi, Sabrina,

you have a solution. your second idea:
Multiple short text and validate the first subquestion with subquestion validation
regexMatch(']pattern to validate date]', Q1_SQ001)

Remember, we all are volunteers. So please do not expect people to be available or online all the time, especially on a saturday at night.
Sometimes you need a little bit of patience.

Thank you Joffm,

How i use this validation and where? it will be better if you have a demo i am beginner

Hi, Sabrina,
in "Edit questions" / "Logic" you find the "Question validation equation: ", where you enter your validaten equation:

The check "is_empty" is to avoid an error message right at the start.

Underneath there is the field "Question validation tip". Here you give nformation to your respondents.
In this case I used the if-statement to distinguish between a "good" message and the "bad" message".

This validation
regexMatch('/^(19|20)\d\d[-](0[1-9]|1[012])[-](0[1-9]|[12][0-9]|3[01])$/',Q01_SQ001)

will validate a date format "yyyy-mm-dd"
but NOT check 30th of february, 31st of april, etc.

On the other side I agree to Tony:
Use question groups and put these two questions into one group.
It is not very time consuming to change the structure of your survey.
First create as many new groups as you need.
Just click "add new group", give a title and save. I should say "Less than 10 seconds per group".
And afterwards you drag the questions into the groups by "organizer".

P.S.
We all were beginners.
So I's davice:
Read the manual,
study the demo surveys, either import them here www.limesurvey.org/manual/Expression_Man...nager_Sample_Surveys
or in the demo installation demo.limesurvey.org/admin/admin.php

Hi, Sabrina,

an addition, if you do not want to change to the group by group structure.

There is an implemented function "checkdate" which really checks dates (including leap years) instead of just checking the format.
Unfortunately the syntax is checkdate(month,day,year), meaning you have to split the entered value into these three parts. Well, easily done by some function (intval and substr).
As you know the structure of the date (e.g. "yyyy-mm-dd") you can say:

checkdate((intval(substr(Q1_SQ001,5,2)),intval(substr(Q1_SQ001,8,2)),intval(substr(Q1_SQ001,0,4)))
Remember: substr starts counting at "0".

Total validation:
((checkdate(intval(substr(Q01_SQ001, 5, 2)), intval(substr(Q01_SQ001, 8, 2)), intval(substr(Q01_SQ001, 0, 4)))) OR is_empty(Q01_SQ001))


And the tip could be:
{if((checkdate(intval(substr(Q01_SQ001,5,2)),intval(substr(Q01_SQ001,8,2)),intval(substr(Q01_SQ001,0,4))) OR is_empty(Q01_SQ001)) ,"Please enter a date","Please enter a valid date")}

By changing the substr-values you can adapt to other date formats.

Result:
