QS:Em validation q

質問の検証式 (em_validation_q)

説明

質問全体（複数選択質問をまとめて）を検証する式です。検証条件に合致しない場合、em_validation_q_tip で設定したメッセージが表示されます（CSSスタイルは.errorとなります）。このTIPは.em_q_fn_validationというCSSスタイルが使われ、template.cssの既定では非表示となります。

The main difference between this feature and the subquestion validation equations (em_validation_sq option) is that for this feature, if the question (or question parts) fail validation, then an error message could be shown. For the subquestion validation, each text entry cell (e.g., in an array question type, but it can also be applied to single entry question types) will be styled so that the background color is (light) red.

And here is part of the Show Logic File output that lets you check the accuracy of your expression and ensure that there are no syntax errors:

As you can see, the validation equation tests that both the email and phone number are either empty or match a regular expression filter.

The validation tip only shows the warning message if the phone or email appears invalid.

 Hint: In order to create complex validation messages, read about the usage of the Expression Manager.

 Hint: Remember, LimeSuvey uses the Perl syntax for regular expressions, so they should start and end with / (slash character)!
