SurveyToGo Studio Manual

Overview

When capturing photos, videos or sounds, SurveyToGo will automatically generate the attachment name in order to make it unique. While usually there is no importance for the attachment name, sometimes there might be and there might also be a need for you to control the name the attachment is given.

For this purpose, you can utilize a special call back function that enables you to override the default name and assign your own name to the attachment.

Using the “OnGetAttachmentName” call back function

To use the OnGetAttachmentName call back you need to write the following call back function in the “Advanced scripts” of your survey:

OnGetAttachmentName – this call back allows you to alter the name of the attachment that will be generated. It is called each time an attachment is captured and just before the engine decides on the name. Here is an example of the call back function:

function OnGetAttachmentName(inFilePath, inName, inQuestionAttachmentCount, inGlobalAttachmentCount)
{
var retVal = “PHOTO_Q_”+CurrQues+”_ATTACH_NUMBER_”+inQuestionAttachmentCount+”.jpg”;
return retVal;
}

The above function will generate attachment names such as “PHOTO_Q_3_ATTACH_NUMBER_1” utilizing the index of the current question and the number of attachments. You can use any survey logic function in this code.

Important Note: Please make sure you provide the extension name as should be per the file type generated. SurveyToGo doesn’t complete the extension automatically.
