Answer width (answer_width)

Description

This value sets the answer column width by using a percentage system. For example, if you type in this field 40, then 40 percent of the width of the question will be used for answers. The remaining width will be equally divided between the subquestions.

Valid values

• Any integer value from 1 to 100.

Hide tip (hide_tip)

Description

Most questions will usually include a tip that says "Please choose one of the following options" or a hint text on how to fill out the question. This attribute allows you to turn off or on this tips/hints.

These tips/hints include validation criteria messages (such as min/max number of answers, min/max/equals sum value). If hide_tip is enabled, these messages will be hidden. However, if the user enters invalid data, the tips will appear. They will be coloured in red, getting changed to green once the validation criteria are met.

Available options

• On - the tips/hints are hidden;
• Off (default).

CSS class (css_class)

Description

If you want to add special CSS classes to certain questions, you can enter the CSS class name(s) in this box. Make sure you leave an empty space between different class names.

Valid values

• Any text string with a space between different CSS class names.

 Hint: You can also insert an expression in this box ^{(New in 3.0.0 )}. Remember that the output of the expression will not be updated dynamically.

  According to the W3C, CSS class names can contain only the characters [a-zA-Z, and 0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_). They cannot start with a digit, or a hyphen followed by a digit. LimeSurvey encodes CSS classes, but it does not fix it totally.

Relevance help for printable survey (printable_survey_relevance_help)

Description

If you wish to print a survey, you can also print the relevance equations for each question. But, if you wish to offer instead an explanation rather than the expression on the printed form, fill in this box with the text explanation for the relevance equation.

Valid values

• Any text and/or numbers you wish to be displayed on the printable form.

Question validation equation (em_validation_q)

Description

This is an equation that is used to validate the entire question (e.g, all of its parts collectively for a multi-answer question). If the question fails the validation criteria, then em_validation_q_tip message will be displayed (it uses the CSS style .error). This tip uses the .em_q_fn_validation CSS style, which is hidden by default within template.css.

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.

Valid values

• Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.

Example

• You want to collect demographic information from users via a multiple short text question, and you want to validate that the user has entered a valid email address and phone number.

This example shows how the question looks with invalid answers:

And here is what it looks like with one invalid answer:

Here is how you edit a question to enter that information:

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 ExpressionScript.

If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file: Em_validation_q_example.zip.

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

Tip for whole question validation equation (em_validation_q_tip)

Description

If you are using the question validation equation, you can use this box in order to display an optional message as question tip on how the question has to be filled out.

Valid values

• Any string or equation that makes use of the ExpressionScript syntax.

Example

See the example from the question validation equation wiki section- it shows how the tip can be tailored to show which parts of a multiple short text question fail the validation criteria.
