Field - Hidden

Field - Hidden

This type will not be shown to the respondent. The main purpose of this type is to gather extra information without having the respondent knowing it.

For example if we want to capture the browser used by the respondent we could add a Field - Hidden type to our question and by setting the default text to : %%HTTP_USER_AGENT%% we would automatically capture the browser of the respondent for our results.

Type Settings

Answer Text is the text that will be shown next to the selection item (radio, checkbox) or inside the dropdown list.
Image URL we can give an image URL (http://www.mydomain.com/myimage.gif) in order to show it instead of showing the answer text.
Type allows us to change the current type of the answer we want in our survey. Respondent answers already collected will not be deleted if we change the type.
Mandatory allows us to set if the textbox field requires to be filled. This check is done server-side.
Default Text Value allows us to set a default value inside the textbox field. It is also possible to fill the textbox with a default value coming from an external source using following tags :

##yourquerystringvariablename## will set the default text with a query string variable's value.
@@yoursessionvariablename@@ will set the default text with a session variable's value.
&&yourcookievariablename&& will set the default text with a cookie variable's value.
%%servervariablename%% will set the default text with a server side variable's value.
Pipe Alias allows us to specify an alias that we can use in other questions to pipe the textbox field value. To learn about piping and pipe alias we suggest reading the Piping Introduction.
Reporting Alias is the text that can be shown instead of the answer text inside our reports.
Extended Report Filter we will be able to use directly the text answers of the respondent as a filter in the General Report Settings. To learn more about piping and extended report filters we suggest reading the Extended Filter Introduction.
