Attributes for Field Settings

1: Attributes for Field Settings

1.1: allowDupe - Set to Enable Multiple Submissions

The allowDupe attribute allows you to control whether a respondent can resubmit their results using the same UUID. Once the respondent has submitted their answers, if allowDupe="1" is specified, they can use the back button to change their responses and resubmit any number of times.

Upon submitting the data again, a new entry in the dataset will be created with the their new responses using the same record and UUID. Their previous responses will not be overwritten.

This attribute is VERY RARELY useful and more common in phone-based surveys.

There is a 60-second period in which duplicate responses are discarded. After 60 seconds, a respondent may submit their responses again.

1.2: allowedCountries - List of Allowed Countries

The allowedCountries attribute controls exactly which countries should be allowed to take the survey. Specify the allowed countries using their lower-case ISO 3166-1 alpha-2 country code (e.g. allowedCountries="us,fr,de").

All countries not specified and IP addresses which cannot be resolved will be excluded from the survey.

As shown below, you may override the system error message that is shown to excluded respondents:

<res label="sys_invited.geoip">You are not permitted to take this survey from your 

1.3: alwaysSaveData - Set to Allow Data Load at Page Submission 

The alwaysSaveData attribute allows you to refine the functionality of loadData below so that respondent data is loaded upon page submission, rather than survey completion. If alwaysSaveData="1" is specified, respondent data is continuously saved and new data is applied to each record after each survey page.

Requires use ofloadDataand thatbrowserDupes="".

1.4: autosave - Set to Auto Save Respondent Progress

The autosave attribute controls the ability to save a respondent's state into a database file after every page. If autosave="1" is specified, a respondent may leave the survey and come back later to the same page where they left off. They will have the option to continue from that point or restart the survey.  Information about how a survey is restored from an autosave is recorded in the survey.log file.

This only works if the respondent has cookies enabled and enters the survey using the same browser. To customize this behavior, see autosaveKey.

1.5: autosaveKey - Set the Auto Save Key Variable

The autosaveKey attribute allows you to create a variable to save a respondent's progress by.

By default, the autosave attribute uses a cookie to store the necessary information and the respondent must enter the survey using the same browser to continue from the last known position. You can, however, use one or more extraVariables to store this progress information by (e.g. autosaveKey="source,GID"). A respondent will be able to enter the survey and continue where they left off using this variable (e.g. /proj1234?source=asdf1234). If more than one variable is provided, the first one (e.g. source) is checked before the second one (e.g. GID).

Use the autosave script to clear saved progress for respondents. For example:
   autosave SURVEY_PATH list (view autosaved keys)
   autosave SURVEY_PATH delete list.txt (delete keys in list.txt)

[user@server proj1234]$ autosave . list
Assuming . refers to selfserve/9d3/proj1234
1 keys total
[user@server proj1234]$ echo "source:asdf1234" > delete_keys.txt
[user@server proj1234]$ autosave . delete delete_keys.txt
Assuming . refers to selfserve/9d3/proj1234
1 keys deleted, 0 missing

1.6: browserDupes - Set to Disable Browser Duplication

The browserDupes attribute can be set to "cookie", "safe", "strict", or "" (blank) and allows you to control how duplicates are checked. When set, respondents can only complete the survey once and the system stores a cookie to remember them for 1 year.

If browserDupes="" is specified, the browser is not checked for duplication.

Setting Description
cookie (default) uses a cookie to store and check duplication data
"" (blank) no browser duplication checks are made
safe enables duplication checking by cookies, HTML5, ETag and Flash methods
strict enables duplication checking by experiment fingerprinting technology

1.7: closed - Set the State of Survey to Closed

The closed attribute controls the status of the survey. If closed="1" is set, then no further respondents will be allowed into the survey.

Instead of using this attribute, you may want to set the state attribute to "closed".

1.8: builder:cname - Add a CNAME to the Survey

The builder:cname attribute allows you to add a pre-configured CNAME to your survey. For example:


CNAME's must be configured within a company directory prior to use in a survey. Click here to learn more about CNAME configuration and setup.

1.9: fingerprint - Specify What Fingerprinting Information to Capture

The fingerprint attribute can be set to "none", "all", "etag", "browser", "flash", or "html5" and controls which variables are captured for fingerprinting respondents.

If fingerprint="all" is specified, 4 new variables will be captured in the dataset: fp_html, fp_etag, fp_flash and fp_browser. These variables will be readily available for processing during the survey or in a virtual question. (Requires a compat level of 109+)

1.10: forbiddenCountries - List of Countries Not Allowed

The forbiddenCountries attribute controls which countries should be forbidden from taking the survey. Specify the forbidden countries using their lower-case ISO 3166-1 alpha-2 country code (e.g. forbiddenCountries="us,fr,de").

All respondents from the specified countries or with an IP address which cannot be resolved will be excluded from the survey.

1.11: loadData - Specify Variable Key to Load Existing Data

The loadData attribute allows you to load a respondent's data based on a variable so that they can modify their existing answers.

For example, if loadData="source" is specified and a respondent enters the survey with a source that has previously completed the survey, all of the responses from that previous session are loaded.

Requires that browserDupes="" and that the variable being used is not set to be unique.

1.12: loggedInCanSubmit - Set to Allow Logged-In User Submission

The loggedInCanSubmit attribute enables staff members and logged-in users to submit data. If loggedInCanSubmit="1" is specified, staff and logged-in users will be able to record their data into the survey.

1.13: markerTimeout - Specify the Time until Markers Are Released

The markerTimeout attribute is an integer value that controls the number of seconds before a partial respondent's markers stop counting in the quota system.

The default, 900 (15 minutes), means that a respondent who enters the survey and qualifies for some markers (e.g. /Gender/Male) and walks away from the computer for some time, the quota will become available for another respondent after the timeout period.

The markerTimeout timeout also affects the "in progress" marker that is set on the respondent once they enter the survey. For example, if a respondent enters the survey on a computer using ?source=1234, then the respondent will have to wait markerTimeout number of seconds before being allowed back in on another computer.

1.14: persistentExit - Prevent the Wrong Exit URL from Being Displayed

The persistentExit attribute is a boolean value the affects only duplicate UUIDs and prevents a respondent from being redirected to the wrong exit page if a survey is resubmitted.  If this attribute is set to:

  • presistentExit="0", the status that matches a respondent's current completion status is used for the the redirect.  This is the default.
  • persistentExit="1", a respondent is redirected using their most recently used exit status (assuming the <exit> tag has not been removed).

persistentExit="1" is not compatible with the browserDupes attribute.

1.15: requires - Set to Require JavaScript Enabled

The requires attribute applies to surveys with a compat level less than 111. If requires="javascript" is specified, then all respondents entering the survey must have JavaScript enabled.

For compat="111+" surveys, JavaScript is always required.

1.16: secure - Set to Force HTTPS Connection

The secure attribute is a boolean value that allows you to force respondents to use HTTPS at all times when taking the survey. If secure="1" is specified, then all respondents will be forced to use a secure connection..

1.17: setup - Setup the Survey Boilerplate

The setup attribute is a comma-separated list of options to configure your project. This attribute accepts any of the following: quota, time, decLang and term.

If setup="term, quota, time, decLang" is specified, the survey, just like mutators, will create virtual questions to capture information related to terminates, quotas, interview time and language, respectively. You can view this information from the virtual question tables displayed on reports.

Note: Compat level 133+ is required for the default vterm table.

More information about the decLang variable can be found here.

1.18: ss:disableBackButton - Set to Disable Browser Back Button

The ss:disableBackButton attribute is a boolean value that controls whether the browser's back button should be enabled for respondents.

If ss:disableBackButton="1" is specified, then respondents will not be allowed to use their browser's back button.

1.19: state - Set the Survey's State

The state attribute sets the survey status.

A survey's state can be any one of the following: dev, testing, live or closed. Each state has unique capabilities:

State Description
dev This is the initial state of a project for Decipher cloud users when starting a new project. This state is only visible to cloud users. Running simulated data is OK. Fatal errors are suppressed.
testing This is for client testing. Simulated data is OK. Fatal errors are suppressed.
live This is for actively collecting respondent data. Simulated data is not OK. Fatal errors generate notifications to team members.
closed This is when the survey is not actively collecting data. Simulated data is not OK. Once set, respondents will have one hour to finish.

1.20: truesample - Specify TrueSample Validation & Data Capture

The truesample attribute controls the validation settings for TrueSample surveys.

The attribute may be set to one or more of the following: real, unique, engaged, qualified or off. These will enable the TrueSample system and generate non-virtual questions that will capture the data returned from TrueSample.

1.21: unique - Specify a Required Unique Variable

The unique attribute is used to limit access to the survey.

Supply an extraVariable (e.g. source) as an argument and when a respondent enters the survey, the system will check this variable passed in the URL (e.g. /proj1234?source=0zYxtl4) against the invited.txt file located in the survey directory. If the variable's value is present in this file and a respondent using that value hasn't already completed the survey, the respondent will be allowed to take the survey. The unique attribute ensures that there will not be any duplicate respondents to the survey and that only authorized users will take the survey.

This is similar to specifying a sample source <var> element with unique="1" and filename="invited.txt" specified.

<var name="source" unique="1" filename="invited.txt"/>

Adding unique="1" to a survey will create an additional database which stores respondents' unique variables.

1.22: uniqueOnly - Set to Prevent Validating With invited.txt

The uniqueOnly attribute is a boolean value that enables you to use the unique attribute mentioned above without the use of the invited.txt file.

If uniqueOnly="1" is specified, the variable provided in the unique attribute must still be unique but will not reference the invited.txt file.

This is similar to specifying a sample source <var> element without specifying a filename.

<var name="source" unique="1"/>

1.23: ss:enableNavigation - Add a Back Button to the Survey

The ss:enableNavigation attribute is a boolean value that enables you to add a "Back" button to the survey.

If ss:enableNavigation="1" is specified, then a "Back" button will be displayed next to the Continue/Finish buttons. This button will only be shown if there is previous data to go back to.

When the "Back" button is clicked, the previous survey page will be loaded with the data that was submitted and the respondent will have an opportunity to modify their responses and proceed forward (or backward, again).
