Általános opciók
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.

Display dropdown boxes (dropdown_dates)
Description
If enabled, the date/time question type will display a dropdown box to the respondents from where to choose the date/time, instead of the default popup.
Available options
- On
- Off (default)
Example
If it is turned on, the question will be displayed in the following way:
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).
Month display style (month_display_style)
Description
The months can be displayed to the respondents in three ways: by using their short names (Jan, Feb, etc.), full names (January, February, etc.) or the number/position of the month in the yearly calendar (01 for January, 02 for February, and so on).
Available options
- Short names
- Full names
- Numbers
Question theme (question_theme)
Description
It allows you to use customized themes for the respective question.
Available options
- Your created question themes which are located under the Question themes in the Themes panel.
See: Question themes
Note: This feature is under development at the moment.
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.
Minimum date (date_min)
Description
This question attribute can be used to set the minimum value for a date question (in y-m-d format or any English valid string - see below for more details). It can be used for both popup and dropdown display options. If a minimum date is not set, then 1.1.1900 is used as default.
Attention : The Expression Manager validation option can also be used for setting up a "minimum date". However, if you you use the popup calendar and the expression relies on a previous question located on the same page, the year will not be displayed correctly in the popup calendar.
Valid values
- Any date value in format YYYY-MM-DD (eg., 2017-08-24);
- Any year value;
- Any English string : "now", "-10 years", "tomorrow";
- Reference to another date/time question : AnotherDateQuestion (using the question code);
- Expressions : With expressions, a minimum date can be dynamically calculated. For example, you can use a date from a previous answer + 3 days as a minimum for the present question by entering: date("Y-m-d",strtotime(departuredate)+3*60*60*24).
Maximum date (date_max)
Description
This question attribute can be used to set the maximum value for the date question (in y-m-d format or any other English valid string - see below for more options). It can be used for both popup and dropdown display options.
Attention : The Expression Manager validation option can also be used for setting up a "maximum date". However, if you use the popup calendar and the expression relies on a previous question located on the same page, the year will not be displayed correctly in the popup calendar.
Valid values
- Any date value in format YYYY-MM-DD (eg., 2018-08-24);
- Any year value;
- Any English string : "now", "-10 years", "tomorrow";
- Reference to another date/time question : AnotherDateQuestion (using the question code);
- Expressions: With expressions, a date can be dynamically calculated. For example, you can use a date from a previous answer + 3 days as a maximum date for the present question by entering: date("Y-m-d",strtotime(departuredate)+3*60*60*24).
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.

Date/Time format
Description
This question option can be used to specify a custom date format. If it is empty, the survey date format will be used.
Valid values
- The d/dd,m/mm,yy/yyyy,H/HH,M/MM formats can be used to display the date and/or time, while "-", ".", "/", ":" can be used as separators.
Examples
- yyyy-mm-dd - year-month-day;
- dd.mm.yyyy HH:MM - day.month.year Hour:Minute;
- HH:MM - Hour:Minute (only the time can be selected);
- yyyy/mm - year/month.
Minute step interval (minute_step_interval)
Description
Hint: This feature changed with version 3.14.12
It's used only input format makes use of minutes ("MM") .
Valid values
- Any numerical value smaller than 60. Adding a value bigger than 60 is redundant -> only "0" or "00" will be displayed in the dropdown box as possible answers.
Example
In the below example, the minute step interval option was set up to 7:

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.

Dátumok és ExpressionScript: Speciális érvényesítés és számítás
A Limesurvey (2.05+ és újabb verziók) meglehetősen egyszerűvé teszi a dátumok érvényesítését a dátum_perc és date_max mezőkben (lásd fent). Használja ezeket, amikor csak lehetséges. Ha fejlettebb ellenőrzésre van szüksége, akkor előfordulhat, hogy a dátumokkal dolgozhat (és számíthat) az ExpressionScript és az strtotime() függvény használatával. Kiszámítja a másodpercek számát 1970. január 1-től egy adott dátumig.
Példa: ha egy kérdésszövegben meg szeretné jeleníteni, hogy hány nap telt el egy indulás dátuma óta (ez egy korábbi kérdésben kérdezett) és ma, akkor használhatja a {(strtotime("now ")-strtotime(departure))/60/60/24}.
Kérjük, vegye figyelembe, hogy az strtotime() sok különböző formátummal működik, de nem mindegyikkel! Például a Limesurvey alapértelmezett dátumformátuma (HH-NN-ÉÉÉÉ) a NEM működik az strtotime() függvényben. Kérjük, állítsa be felmérését a következő dátumformátumok valamelyikére a problémák elkerülése érdekében: ÉÉÉÉ-HH-NN, ÉÉÉÉ/HH/NN, NN.HH.ÉÉÉÉ, HH/NN/ÉÉÉÉ vagy NN-HH-ÉÉÉÉ.
A Limesurvey dátumai karakterláncként (szövegformátumban) vannak elmentve. Az ExpressionScript a kifejezés minden dátumát a szabványos "éééé-hh-nn ÓÓ:PP:SS" formátumba konvertálja. Ez sokkal könnyebbé teszi a dátumok összehasonlítását egy kifejezésben (pl. "dátum1>dátum2"). Ha a kérdésben feltett formátumú dátumkarakterláncra van szüksége, használja a ".shown" attribútumot (pl.: {születési dátum.megjelenítés} napon született.)
