質問タイプ - 配列（テキスト）
From LimeSurvey Manual
概略
配列（テキスト）質問タイプは、縦軸のサブ質問と横軸のサブ質問でできた、テキストボックスの配列に回答する質問タイプです。
例: Array_Texts_Example_text.zip
この質問タイプで数値の回答に限定することもでき（"数のみ"の質問属性を参照）、合計を表示によって縦・横・両方の合計を表示させることもできます。
例: Array Texts Example text numbers.zip
全般オプション
回答必須
説明
このオプションにより、アンケートの質問に回答者が必ず答えるようにすることができます。回答必須の質問に回答しない場合、回答者は先に進むことができません。ある質問に複数のサブ質問があり、特定のサブ質問のみを回答必須とする場合は、ロジックタブの下にある最小回答数属性を使用します。
プレインストールされたテーマを使用している場合、必須の質問属性を有効にすると、質問の横に赤いアスタリスクが表示されます。 表示したくない場合は、こちらを参照してください。
設定可能な値
- オン - 参加者が次のページに進む前に質問に回答する必要があります。回答の選択肢に「回答なし」は表示されません。
- ソフト - 質問に回答せずに次のページに進もうとすると警告が表示されますが、参加者は警告を無視して先に進むことができます。「回答なし」オプションは表示されます（アンケートの表示設定で有効になっている場合）。
- オフ（規定値） - 質問に回答しなくてもよくなります
条件（以前の"出現条件"）
説明
条件の結果値が「1」または「true」になると、質問がアンケートの中で「関連する」、つまりアンケート参加者に提示されます。その他の場合は質問は表示されません。どのような質問でも関連式を指定することができます。この関数は条件の後継であり、より複雑な条件ロジックをサポートします。
構文ハイライト
条件を保存するたびに、検証され構文がハイライトされます。エラーにも色がつくので、すぐに気づいて直すことができます。
有効な値
- ExpressionScriptの構文に従うすべての条件（中括弧は外す）。
例
構文ハイライトによい例があります。
（正規表現を使った）検証 (preg_validation)
説明
この設定は、質問内のすべての値の検証に使う正規表現を指定するものです。
質問やサブ質問への回答のどれかがこの検証要件に適合しない場合、テキスト入力欄の背景色が赤くなり、回答者が直すべき場所に気づきやすくなっています。回答者が送信ボタンを押さなくてもそれぞれの質問を検証することができます。
有効な値
- 有効な任意の正規表現
例
- こちらにいくつか例があります
表示
（サブ）質問幅 (subquestion_width)
説明
パーセント形式でサブ質問の列幅を設定します。例えば、この値を60に設定すると、質問の幅の60%がサブ質問テキスト（最も左の列）に割り当てられます。残りの幅が回答オプションに均等に割り当てられます。
有効な値
- 1から100までの整数
TIP非表示 (hide_tip)
説明
多くの質問では、「以下からひとつだけ選択してください」のような注記（tip）や質問への回答方法を示すテキストが表示されます。この属性で、tipやヒントを表示するかしないかを設定できます。
こうしたtipやヒントには、検証基準（最小／最大回答数、最小／最大／合計値）に関するメッセージが含まれます。hide_tipをオンにすると、こうしたメッセージは表示されませんが、無効なデータを入力するとtipが表示されます。赤色で表示されますが、検証基準を満たすと緑色になります。
利用可能な設定値
- オン - tipやヒント非表示
- オフ（規定値）
回答のランダム表示(random_order)
説明
非推奨の回答オプション : 5.5.0から、この属性は回答の選択肢の順序付けには使用されなくなりました。QS:Answer_order/jaを参照してください。
この属性により、回答の選択肢／サブ質問の順番は無視され、ランダムに並べ替えられます。このオプションにより、アンケートの偏りをなくすことができます。サブ質問がある場合、サブ質問の順番はランダムになりますが、回答の選択肢の順番はランダムにはなりません。
有効な値
- はい - 参加者がアンケートを開始するときにランダム化する
- いいえ（規定値）
テキスト入力ボックスのサイズ (input_box_size)
説明
この機能は、テキスト領域（テキスト入力ボックス）のサイズを指定するものです。何も設定しなければ、LimeSurveyは入力ボックスを既定のサイズで表示します。この設定で既定の動作を変えることができます。
ボックスを次の行に移動させたい場合、ラッパーのサイズを大きくします。テキスト入力幅属性の値を大きくします。有効な値
- 任意の数値
Repeat headers (repeat_headers)
Description
This option can be used if you add to a question a high number of subquestions. If this is the case, use this option in order to tell LimeSurvey after how many subquestions should the headers be repeated.
Valid values
- Any integer values;
- The default value is 0 - the repeat headers function is deactivated.
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: https://manual.limesurvey.org/Question_themes
Note: This feature is under development at the moment.
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)
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.
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.
Input
Input maximum characters (input_max_characters)
Description
The following option allows you to type in a numerical value that will represent the maximum number of characters that can be entered by the survey respondents in the answer text box(es) of the respective question.
Valid values
- Any numerical value
Example
- If you wish the survey participants to type in a short and concise answer, introduce within the input maximum characters field a small number (e.g., 10-15).
Logic
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.
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.
- 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.
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.
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.
Array exclusion filter (array_filter_exclude)
Description
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.
- 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
Furthermore, each of these types of questions can filtered.
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.
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.
Example
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.
This example can be downloaded from the following link: Limesurvey_group_array_filter_exclude.zip. Import this question group into your LimeSurvey installation.
Array filter style (array_filter_style)
Description
This function allows you to choose how the array filtered subquestions are displayed. They can either be "hidden" or "disabled".
To learn how to filter subquestions, please read the following wiki section.Available options
- Hidden (default) - if this option is selected, then the previously selected subquestions will not be displayed in the second question.
- Disabled - if this option is selected, then the previously selected subquestions will be greyed out and become unselectable.
Example
If you wish to use the "disabled" option, then the previously selected subquestions will be displayed like this:
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.
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.
If you wish to import the example from above into your LimeSurvey installation, download the following .lsq file: Em_validation_q_example.zip.
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.
Sub-question validation equation (em_validation_sq)
Description
This is an equation that is used to validate each subquestion (text field) individually. Any text field that does not pass these validation conditions will have its background color turned pink (using the .em_sq_fn_validation CSS style) to highlight the error. Note that this is available in addition to the regular expression-based validation option.
Valid values
Any equation that makes use of the ExpressionScript syntax, without surrounding curly braces.
Examples
For example, if you want to allow only numbers that are a multiple of 3 as answers, the equation would be:
(this / 3) == floor(this/3)
The reserved variable this is automatically replaced by a reference to the active text entry cell.
Tip for sub-question validation equation (em_validation_sq_tip)
Description
If you are using em_validation_sq, this is an optional message/tip that will be displayed if the introduced answer is incorrect.
Valid values
- Any string
Example
- Continuing the example of validating emails, the tip might be "Please enter valid email addresses."
Other
Insert page break in printable view (page_break)
Description
This attribute is only active when you actually print a survey from the Printable View. It forces a page break before the question.
Available options
- On
- Off (default)
Numbers only (numbers_only)
Description
If you enable this option, the participant can only enter numbers in the text box(es).
For the equation question types, this setting indicates that the result could only be a number, not a string. This will guarantee proper calculations/conversions in follow-up equations regarding the decimal mark.
Behavior by question type
- Default: If the subject enters a value that is not a number, that value is immediately cleared from the text box so that the subject can enter an appropriate value.
- Array (Texts): If the numbers only option is disabled, the "Show totals for" and "Show grand total" options will be overruled, while the total text boxes will not be displayed.
- Equation: Enabling this option will force the equation results to be converted to a numeric value. If the equation result is not a number (and not blank), the equation will return NaN, being saved as an empty string in the response table.
Available options
- On
- Off (default)
Show totals for (show_totals)
Description
If enabled, the totals for either rows, columns or both rows and columns will be displayed.
The totals are displayed only if the Numbers only option is enabled.Available options
- Off (default)
- Rows
- Columns
- Rows & columns
Example
Show grand total (show_grand_total)
Description
If enabled, the grand total for columns (or rows) will be displayed in the bottom right part of the array.
The grand total is displayed only if the Numbers only option is enabled.Available options
- On
- Off (default)
Example
Statistics
Display chart (display_chart)
Description

Note: To have the chart displayed on the last page, you have to enable the following options:
- public statistics survey setting from the presentation & navigation settings
- show graphs survey setting from the presentation & navigation settings
- public statistics question attribute, and
- display chart question attribute.
Available options
- On
- Off (default)
Chart type (chart_type)
Description

Note: Do not forget to change the question and survey settings in order to have the charts displayed at the end on the survey. For more details, check the wiki section on the display chart question attribute.Available options
- Bar chart
- Pie chart
- Radar
- Line
- PolarArea
- Doughnut
