Validation (using regular expressions) (preg_validation)

Beschreibung

This option lets you specify a regular expression with which you can validate all the parts of a question.

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.

Hide tip (hide_tip)

Beschreibung

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).

Breite Eingabefeld (text_input_width)

Beschreibung

This attribute sets the width of the text input boxes (of the "wrapper" of the text input boxes). The input box is used to introduce an answer to the (sub)question. If the value of the width is sufficiently high, then the text input box will be displayed on the next line. Please note that this option does not set the size of the input or the width of the entire column!

Available options

• Default: If selected, a default value will be allocated to this attribute in such a way to have both the label and its corresponding text input box on the same line. For example, if the text input box width is 41%, the value of the width of the text input box will be a value that allows both the label and the input box on the same line (58% in this case). If the width of text input box was higher than 58%, then the text input box would be displayed on the next line.
• 8%; 17%...92%, 100%: the bigger the selected value, the larger the width of the text input box.

Beispiel

• If you wish to have the input part displayed below the subquestion/label, select the 100% option from the dropdown list.

Zufällige Antwortreihenfolge (random_order)

Beschreibung

Dieses Einstellung bewirkt, dass LimeSurvey die bestehende Reihenfolge der Antworten/Teilfragen dieser Frage ignoriert und durch eine zufällige Anordnung ersetzt. Die Anordnung der Antworten zu einer Frage wird momentan auch bei jedem Zurück- oder Vor-Navigieren vertauscht. Wenn ein Benutzer den Fragebogen durchgeht, findet er die also die Antworten nie in derselben Reihenfolge vor. Durch eine zufällige Verteilung soll gewährleistet werden, dass Benutzer keine Neigung/Tendenz zu einzelnen Antworten entwickeln können. Setzen Sie dies auf 'An' um es zu aktivieren. Bitte beachten Sie, dass wenn eine Frage Teilfragen hat, dann werden die Teilfragen randomisiert, nicht die Antwortoptionen.

Verfügbare Optionen

• Bei jedem Laden der Seite neu setzen
• Aus (Standard)

Example

See this example (outside link) to better understand how to use different LimeSurvey randomization features.

Always hide this question (hidden)

Beschreibung

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 Expression Manager.

Note: A common question type that is used with this function is the Equation one.

Available options

• On
• Off (default)

Logik

Minimum answers (min_answers)

Beschreibung

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 Expression Manager syntax, without surrounding curly braces.

Beispiel

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.

Maximale Antworten (max_answers)

Beschreibung

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 Expression Manager syntax, without surrounding curly braces.

Beispiel

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.

Matrix Filter (array_filter)

Beschreibung

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. Check the below example to better understand how the whole system works.

Kaskadierung

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.

Matrix Filter Beispiel

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.

Array exclusion filter (array_filter_exclude)

Beschreibung

The Array filter exclusion setting allows you to use any multiple choice question to select or set which responses are NOT 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, By column)
• Array (Dual Scale, Text, Numbers)
• Ranking

Außerdem kann jeder dieser Fragetypen an sich gefiltert werden.

The only exception is Array by column which can filter other questions, but it cannot be filtered.

How to set it up

Enter the question code of a multiple options question in the array exclusion 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 non-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 exclusion filter' box to start the filtering process of the answers. Only the answer options that are NOT selected in question Q1 will be visible in your 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 exclusion filter function will not filter the answers to the first question. Check the below example to better understand how the whole system works.

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.

Beispiel

Let's see together the below example:

In the screenshot from above, we got two questions. The first one is a multiple choice question type, while the second one is a multiple choice with comments question type. The answers you provide in the first question will be excluded from the second one. For example, if you select the ComfortUpdate option (that has the subquestion code 'SQ1') and the Plugin option ('SQ4'), the 'SQ1' and the 'SQ4' subquestion correspondents from the second question will be excluded. In our screenshot, we can observe that only the unselected options in the first question and displayed in the second one.

Randomisierungsgruppenname (random_group)

Beschreibung

Ordne die Frage der angegebenen Randomisierungsgruppe zu. Alle Fragen in der gleichen Gruppe werden in einer zufälligen Reihenfolge erscheinen.

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

Gültige Werte

Geben Sie irgendeine Zeichenkette ein (zum Beispiel 'gruppe1'). Alle Fragen, die die gleiche Zeichenkette gesetzt haben, werden in der Umfrage jeweils zufällig durcheinander ausgetauscht.

Validierungsgleichung für die ganze Frage (em_validation_q)

Beschreibung

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 Expression Manager 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 Expression Manager.

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)!
