QS: Validare preg
From LimeSurvey Manual
Validare (folosind expresii regulate) (preg_validation)
Descriere
Această opțiune vă permite să specificați o expresie regulată cu care puteți valida toate părțile unei întrebări.
If any question or subquestion value does not meet the validation requirements, the background colour of the text entry field will be changed to red so that users can easily see which parts of the question need to be corrected. Thus, you can do on-page validation. In this way you will not need to wait for the user to click on the submit button to validate the respective question.
