質問タイプ - 自由回答(非常に長い)
From LimeSurvey Manual
概略
この質問タイプは、複数行のより長いテキスト入力を得ることができます。
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。
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
表示行数 (display_rows)
説明
すべてのコメントをチェックするためにスクロールバーを使わずに表示する行数を指定します。設定値より多くの行がある場合、スクロールバーが表示されます。"自由回答(長い)"質問タイプの既定値は5、"自由回答(非常に長い)質問タイプ"は30です。
有効な値
- 0より大きい整数
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)
入力ボックスの幅 (text_input_width)
説明
この属性では、テキスト入力ボックス(のラッパー)の幅を設定します。入力ボックスは(サブ)質問に対する回答のために使われます。幅の設定値が十分に大きい場合、テキスト入力ボックスは次の行に表示されます。このオプションは、入力部分のサイズや絡む全体の幅を設定するものではないことに注意してください。
設定可能な値
- 規定値: 選択すると、規定値はラベルと対応するテキスト入力ボックスが同じ行になるよう設定されます。例えば、テキスト入力ボックスの幅が41%の場合、テキスト入力ボックスの幅の値はラベルと入力ボックスが同じ行になる値(この場合58%)になります。テキスト入力ボックスの幅が58%以上の場合、テキスト入力ボックスは次の行に表示されます。
- 8%; 17%...92%, 100%: 選択値が大きくなるほどテキスト入力ボックスが大きくなります。
例
- サブ質問/ラベルの下に入力部分を表示させたい場合は、ドロップダウンリストから100%を選択します。
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。
有効な値
- 任意の数値
質問テンプレート (question_theme)
説明
それぞれの質問にカスタマイズされたテンプレートを適用することができます。
利用可能な設定
- テンプレートパネルの質問テンプレートにある作成済みの質問テンプレート
参照: https://manual.limesurvey.org/Question_themes
説明
オンにすると、その質問は常に表示されません。この機能は以下のような場合に使用します。
- 質問にURLをあらかじめ入力しておき、それを画面に表示させたくない場合。それぞれの質問がページに埋め込まれないため、アンケートで使用される条件が無効になります。
- ExpressionScriptで値をその場で保存または計算したい場合。
利用可能な設定値
- オン
- オフ(規定値)
CSS クラス (css_class)
説明
特定の質問に特別な CSS クラスを追加するときは、この欄に CSS クラス名を入力します。クラス名を列挙するときはスペースで区切ります。
有効な値
- 任意の文字列と CSS クラスを区切るスペース
Input
Maximum characters (maximum_chars)
Description
This allows you to set the maximum number of characters that can be entered for a text based question. Entering a value of, say, 20 will mean that the participant cannot enter any more than 20 characters.
Valid values
- Any integer value above 0
Logic
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)
Statistics
Display chart (display_chart)
Description
This attribute allows the survey administrator to choose if a chart that contains the question results should be displayed to the survey participants after they filled out the survey.
- 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
This attribute allows the survey administrator to choose which type of chart will be displayed to the respondent once he/she finished filling out the survey.
Available options
- Bar chart
- Pie chart
- Radar
- Line
- PolarArea
- Doughnut
Timer
Time limit (time_limit)
Description
Setting the time_limit attribute on a question will cause a countdown timer to begin counting down as soon as that question/page is loaded. At the expiry of the countdown timer the question will either automatically move on to the next page or become read-only.
Valid values
- Any positive integer number
Example
Set it to 240 to count down from 4 minutes (240 seconds).
<translate>
<onlyinclude>
Time limit action (time_limit_action)
Description
Sets the action performed when a time_limit has expired. By default the action for a time limit is "Warn and move on", which means the system will give a short warning that the time limit has expired before saving the question and effectively automatically clicking "Next >>". The alternative choices are to:
- "Move on without warning", which automatically clicks the "Next >>" button after the timer is finished but without any warning message.
- "Disable only", which disables changes in the question so the participant can't change anything, but doesn't automatically click the "Next >>" button.
This setting is only applicable if the general time limit setting is activated.
Available options
- Warn and move on (default): will warn the participant that the time has expired, and then click the next button
- Move on without warning: will immediately click the next button after the time limit has expired
- Disable only: will disable the answer after the time limit has expired but not automatically click next
Additional information
Instead of relying on mandatory questions, you may use expressions (read more about question and subquestion validation equations) to make the user not leave empty the answer fields. To see how the validation equations work, check the following example.
In the case in which you want to apply a timer to a question group, activate the group-by-group survey mode, set up a question to use the time limit functionality, and choose the warn and move on (default) option as time limit action. Once the question timer expires, the survey will move to the next page.

Time limit disable next (time_limit_disable_next)
Description
It allows disabling the "next" button while a time_limit countdown is occurring. Normally, even if the time limit countdown is active, if the participant wants to click "Next" and move on to the next question or question group, they can simply click on the "Next" button (thus cutting short the time spent on the question or question group). By activating this function, the next button will appear greyed out and will not be available until the countdown timer has finished.
This settings is only applicable if the general time limit setting is activated.
Available options
- On - The "Next" button will be disabled until the time limit countdown is complete.
- Off (default)
Time limit disable prev (time_limit_disable_prev)
Description
It allows disabling the "previous" button while a time_limit countdown is occurring. Normally, even if a time limit countdown is active, if the participant wants to click on "Previous" and move to the previous question or question group, they can simply click on the "Previous" button (thus cutting short the time spent on the question or question group). By activating this function, the previous button will appear greyed out and will not be available until the countdown timer has finished.
This settings is only applicable if the general time limit setting is activated.
Available options
- On - the "Previous" button will be disabled until the time limit countdown is complete.
- Off (default)
Time limit countdown message (time_limit_countdown_message)
Description
Write in this field the text message you wish to be displayed in the countdown timer during the countdown. This setting is applicable only if the general time limit setting is activated. If nothing is written, the the field will use the default value: "Time remaining".
Time limit timer CSS style (time_limit_timer_style)
Description
It allows (and overrides the default) css styling used to display the countdown timer. The default style value for this attribute will be used if it does not exist, which is: 'width: 150px; margin-left: auto; margin-right: auto; border: 1px solid #111; text-align: center; background-color: #EEE; margin-bottom: 5px; font-size: 8pt;'.
Any text entered into this attribute will overwrite the entire default css style, so you should ensure that care is taken when entering a value for this attribute. A simple way to hide this is to copy the default style into this attribute and add 'display: none;' to the end.
This settings is only applicable if the general time limit setting is activated.
Time limit expiry message display time (time_limit_message_delay)
Description
This attribute sets how many seconds the time_limit_message is displayed before the time_limit_action occurs. If this attribute is not set, it defaults to a value of 1 (1 second).
This settings is only applicable if the general time limit settings is activated.
Example
time_limit_message_delay: 5 = the message displays for 5 seconds
Time limit expiry message (time_limit_message)
Description
This is the text of the message that appears to the participant when the time_limit has expired. By default, this message is "Your time to answer this question has expired". If the time_limit_action attribute is set to "Move on without warning" this message is not displayed. You can set the CSS style for this text in the time_limit_message_style attribute (see below).
This settings is only applicable if the general time limit settings is activated.
Example
time_limit_message: The time limit on answering this question is now up.
Time limit message CSS style (time_limit_message_style)
Description
It allows (and overrides the default) css styling used to display the time limit message. The default style value for this attribute will be used if it does not exist, which is: 'top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: white; z-index: 1002; text-align: center; overflow: auto'.
Any text entered into this attribute will overwrite the entire default css style, so you should ensure that care is taken when entering a value for this attribute. It is strongly recommended that you re-use the z-index value, or that, at least, the z-index value is higher than that used for the time_limit_warning_message_style attribute (which defaults to 1001).
Example
Set to: top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: black; color: white; z-index: 1010; text-align: center; overflow: auto
Time limit warning message timer (time_limit_warning)
Description
With the help of this attribute, you can set the time (in seconds) when the time_limit_warning_message will be displayed before the time limit expires. Setting a value for this attribute activates the time limit warning message.
This settings is only applicable if the general time limit settings is activated. This setting also exists for a second warning message.
Example
If you set this to '20', then the time limit warning message will appear 20 seconds before the time limit countdown reaches zero.
Time limit warning message display time (time_limit_warning_display_time)
Description
It sets for how long the time_limit_warning_message is displayed before it is removed/hidden from the screen. By default, if the time_limit_warning_message appears, it will remain visible until the countdown timer has completed the countdown. If a value greater than zero is introduced in this field, the message will be hidden after that many seconds.
This setting is applicable only if the general time limit setting is activated. This setting also exists for a second warning message.
Example
time_limit_warning_display_time: 10 = The time limit warning message will disappear 10 seconds after its moment of appearance.
Time limit warning message (time_limit_warning_message)
Description
If set up, it displays the text of the warning message which is displayed for a fixed period of time before a time limit expires. The default text is "Your time to answer this question has nearly expired. You have {TIME} remaining." {TIME} is replaced by a formatted description which represents the amount of time left (i.e. "30 seconds", "1 minute or 5 seconds"). This message only appears if the time_limit_warning attribute exists. You can set from the time_limit_warning attribute when the message (time_limit_warning_message) appears.
This question attribute is only applicable if the time limit setting is activated and you set some text in the time limit warning message field. This setting also exists for a second warning message.
Example
Attention: In {TIME} the time limit to answer question will expire.
Time limit warning CSS style (time_limit_warning_style)
Description
It allows (and overrides the default) css styling used to display the time limit warning message. The default style value for this attribute will be used if it does not exist, which is: 'top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: white; z-index: 1001; text-align: center; overflow: auto'.
Any text entered into this attribute will overwrite the entire default css style for the warning message, so you should ensure that care is taken when entering a value for this attribute. It is strongly recommended that you re-use the z-index value, or that, at least, the z-index value be lower than that used for the time_limit_message_style attribute (which defaults to 1002).
This settings is only applicable if the general time limit setting is activated. This setting also exists for a second warning message.
Example
top: 10px; left: 35%; width: 30%; height: 60px; padding: 16px; border: 8px solid #555; background-color: gray; color: white; z-index: 1001; text-align: center; overflow: auto
