Core settings

QS:Defaults


Mandatory

Description

This option allows the survey administrators to request their respondents to answer certain survey questions. If the mandatory questions are not answered, the respondents will not be able to proceed further. If you have a question with multiple subquestions, and you require only certain subquestions to be answered, use the minimum answer attribute located under the Logic tab.

If you use any of the preinstalled themes and the mandatory question attribute is enabled, a red asterisk will be shown next to the question. If you wish to hide it, please check these instructions.


Available options

  • On - Question must be answered before the participant can proceed to the next page - the answer option 'No answer' is never shown.
  • Soft - If the question is not answered, a warning is shown when trying to proceed to the next page - however, the participant can choose to ignore the warning and proceed. Note that the 'No answer' option is still shown (if activated in survey presentation settings)
  • Off (default) - Question can be left unanswered



Option 'Other' (other)

Description

This option is used by multiple choice-type questions and gives you the ability to ask for a selection that is not part of the enumerated answer list.

Available options

  • On
  • Off (default)


These Core Settings are available in Version 1.92 and beyond

Condition (previously "Relevance equation")

Description

If the result value of the condition is "1" or "true", the question is "relevant" in the survey context, i.e. it is shown to the survey participant. If not, the question is hidden. Any survey question allows you to specify a relevance equation. This function is the successor of conditions and supports much more complex conditional logic.

Syntax Highlighting

Whenever you save the condition, it is evaluated and syntax-highlighted. Any errors will be color coded so that you can quickly detect and fix them.

 Hint: To check if all conditions are used correctly within your survey, read about our show logic file feature.


Valid values

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

Examples

Here are good examples of syntax highlighting.


Advanced settings

Label for 'Other:' option (other_replace_text)

Description

Short text string to replace the text "Other" as label for the "other" option.

Note: You can make use of this attribute if you have previously enabled the "other" option located under the general options tab.

Example

Entering a value of "Alternative:" for this attribute would result in the word "Alternative:" being used instead of "Other".


  Issue in LimeSurvey 4.X : It is extremely important to note that this question attribute should only be used in single-language surveys. A translation will be attempted but will only be successful if the translation already exists in the alternate language file (i.e.: translation cannot be made on a survey-by-survey basis). Therefore, to translate your other text, you have to add your other_replace_text to the english .mo file (because this is LimeSurveys baselanguage) and translate this String in each of your surveys languages .mo files.




Random answer order (random_order)

Description

  Deprecated for Answer Options : As of 5.5.0, this attribute is not longer used for ordering answer options. Please see QS:Answer_order


This attribute causes LimeSurvey to ignore the existing order of answer options/subquestions, and instead it orders them randomly. This option permits the survey creator to diminish the survey bias. Please note that if a question has subquestions, the order of subquestions will be randomized, not the order of the answer options.

Available options

  • Yes - Randomize when participant enters survey
  • No (default)


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).



Randomization group name (random_group)

Description

It places the questions into a specified randomization group, all questions included in the specified group being displayed in a random order to the survey respondents.

You can find a sample survey using randomization group name in ExpressionScript sample survey.

Valid values

Just enter any string you like (for example: 'group1'). All question which have set the same string within the randomization group name box will have their place in the survey randomized (=randomly exchanged among each other).


Preview To preview the questions use the preview survey instead of the preview question group function, as the second has been reported to not show the questions in a randomized order.


Always hide this question (hidden)

Description

If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:

  • If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.
  • If you wish to store or calculate a value on the fly via the ExpressionScript - Presentation.
Note: A common question type that is used with this function is the Equation one.

Available options

  • On
  • Off (default)


Minimum answers (min_answers)

Description

This function can be used to ensure that a user selects at least a certain number of answers in a multiple choice question.

Valid values

  • Any integer value above 0
  • Any number
  • Any SGQA code
  • Any question code (variable name)
  • Any equation, using ExpressionScript syntax, without surrounding curly braces.

Example

If set to X (a random number), the users can submit the survey form if they select at least X checkboxes. If this option is utilised for ranking questions, this ensures that at least three items are ranked before allowing the respondent to submit the answers/survey.

Please note that if you use this attribute with Ranking questions, you have to set the question to non-mandatory. Otherwise, all the items need to be ranked which is counter-intuitive if you decide to use the min_answers function too.



Maximum answers (max_answers)

Description

It can be used to limit the total number of answers a user can select in a multiple choice question.

Valid values

  • Any number value
  • Any SGQA code
  • Any question code (variable name)
  • Any equation, using ExpressionScript syntax, without surrounding curly braces.

Example

If set to 2, the user will only be able to check at most two checkboxes or one checkbox + fill the "Other" field (if any). For the Ranking question type, the participant would be able to select maximum two items.



Numbers only for 'Other' (other_numbers_only)

Description

If this attribute is enabled together with the "option other" one (located under the General options tab), only numbers can be typed in by the survey respondents in the "other" textbox.

Available options:

  • On
  • Off (default)



'Other:' comment mandatory (other_comment_mandatory)

Description

It only applies to mandatory questions having an "other answer" option in which the participant can give a free text response ("other comment").

When this setting is activated and the participant selects the other answer (the "other checkbox" or "other answer in a list"), then he will have to give a comment in the "Other comment" input box in order to proceed to the next page.

Note that this option is not available for Multiple Choice questions because the "Other" checkbox status is not recorded in the database for this question type, only the content being recorded. This means that checking the "other" checkbox is just a visual effect that is only meaningful if the text box is filled in: that is why other_comment_mandatory is assumed to be set for this question type.

Available options

  • On
  • Off (default)

Example

If activated for a "Multiple options with comments" question and the user enters a value in the left part of the Other answer but doesn't enter text in the Other Comment part, a warning message will be displayed when he tries to proceed to the next page.



Assessment value (assessment_value)

Description

If assessments are used and one or more subquestions are checked, the value from this field will be added to each checked subquestion, contributing to the final assessment score.

Check the following link to read more on assessments and their usage in LimeSurvey.

Valid values

  • Any numerical values



Array filter (array_filter)

Description

The Array filter setting allows you to use any multiple choice question to select or set which responses are displayed in a subsequent list, array or multiple choice question.

The subsequent questions can be filtered on any array question type, including:
  • Multiple choice
  • Multiple choice with comments
  • Multiple short text
  • Multiple numeric
  • Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, Column)
  • Array (Dual Scale, Text, Numbers)
  • Ranking

Furthermore, each of these question types can be filtered.

The only exception is Array (Column), which can filter other questions, but not itself.

How to set a filter

To set a filter, enter the question code of a multiple options question in the array filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array Filter' box to start the filtering process of the answers. Only the answer options that are selected in question Q1 will be visible in the array_filter-ed question.

If you wish more questions to be filtered via this option, type the question codes in the box separated by semicolons (;).
  The subquestion codes used in the first question must coincide with the subquestion codes from the second one. Otherwise, the array filter function will not filter the answers to the first question. Note: When you want to filter the "other" answer option from the first question, you need to provide a subquestion for this answer in the second question and the subquestion code for this answer needs to be "other". Check the below example to better understand how the whole system works.


If multiple choice allow other setting: you can choose other for subquestion code and filter with other checked or not.

Cascading

The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.

Array filter example

Let's take a look at the following example to better understand the power of this setting:



In the screenshot from above, we got two questions. The first one is a multiple short text question type, while the second one is an array dual scale question type. The answers you provide in the first question will be listed in the second one. Technically, the answers you provide to the subquestions from the first question are filtered and displayed in the second question.

This example can be downloaded from the following link: limesurvey_group_32.lsg. Import this question group into your LimeSurvey installation.

{INCLUDE(page="Advanced question settings",start="!public_statistics",stop="---")}{INCLUDE}

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

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.
