==================
Hi!
I am using LimeSurvey Version 3.28.43+221221 with limited access to advanced configuration settings.
I have a Date/Time question and I would like a message to be displayed if the date chosen is less that 10 days away from the current date.
Example:
Current date : 23.01.2023
Chosen date : 25.01.2023
==> Displayed text : " Your course takes place in less than 10 days, please contact XXX".

Is it possible to do this with a validation equation? Is it possible to do this at all?

Thank in advance for any help!!

Best regards,

Ana


 

Hi, Ana,

something like
{if(!is_empty(chosen) and floor((strtotime(chosen)-strtotime('now'))/(60*60*24))<10,"Your course takes place in less than 10 days, please contact XXX","")}

Hi Joffm,
Thanks for your quick reply and your help! I have tried your equation in my question and unfortunately it doesn't work.
The variable "chosen" is not recognized...
I have tried adding inverted commas but that didn't do the trick either (the equation seems fine in that case but no message is displayed)... any suggestions? The test survey is attached, just in case. Is it possible that any features need to be activated in the theme to allow the equation to work?
Please let me know if you need any further information.
Thanks again for your help!
Have a nice day, Ana

You need to replace chosen with the questioncode of your question.

In your testsurvey you replace "chosen" with "testdate".
 

Updated answer: The question validation equation contains the equation and the question validation tip the text.
The validation is to ensure the right values. In your case every future date with more than 9 days away from the current date.

The equation Joffm has posted is for the question validation tip or can be used in the question text.
Which would just be a warning without blocking answering the question via the validation (which has to formulated to become true when answer is valid).




 

Take a look at the modified survey. Might be still buggy, but check.

Question validation (More than 10 days)
Question validation tip (less than 11 days)  

Hi Jelo,

thanks a lot for the explanations, it works wonderfully! I have used both, the validation equation and the validation tip (for the latter I had to add curly brackets).

I had not realized that "chosen" in Joffm's example was the question code.

Thanks you both for your valuable help!! The support of this community is invaluable!

Have a nice day.

Hi !
Just to complete the info for other interested people:

I found a third option proposed by Joffm in a different thread :
One can use the "minimum date" field of the "display" pane.

Valid values

- Any date value in format YYYY-MM-DD (eg., 2017-08-24);
- Any year value;
- Any English string : "now", "-10 years", "tomorrow";
- Reference to another date/time question : AnotherDateQuestion (using the question code);
- Expressions : With expressions, a minimum date can be dynamically calculated. For example, you can use a date from a previous answer + 3 days as a minimum for the present question by entering: date("Y-m-d",strtotime(departuredate)+3*60*60*24).

Have a nice day!

Hi again,
I am experiencing some weird behavior when using "minimum date" together with an "IF clause" in the question text (see attached question) (the browser I am using is Firefox but the same thing happens with Chrome).
If I set min_date to ' 2 days' and choose the date of today 2 days (that is January 29th, see Image1), the warning of the IF clause is not displayed (but it should because we are less than 10 days away). Does anybody have an explanation/solution for this behavior, please?

If I then change to January 30th all works fine (my warning is displayed, Image2).
 
When I then go back to the 29th my warning is displayed together a second warning message saying that you can only chose dates higher or equal to the 29th (Image3). Is it possible to hide the second warning message?

Thanks in advance.
Best,
Ana
