Lua Scripting Resources

Important Update to Custom Scripting

SurveyGizmo's CustomScript Action now supports the LUA programming language.


Legacy Custom Scripting Language Deprecation Plans 

  1. New accounts (created after October 29, 2018) will only have the option to use Lua in scripts.
  2. As of October 29, 2018 Custom Scripting Actions will default to Lua as the scripting type in the Custom Scripting Action for accounts created before this date. You will be able to switch to the Legacy Custom Scripting; though we highly encourage using Lua.
  3. In the long term, Legacy Custom Scripting Actions will be switched to read-only. Read-only scripts will continue to function; you will just be prevented from editing. The exact date on this is to be determined; we will send notifications well ahead of time.


 Go to our Legacy Scripting Documentation.

While SurveyGizmo is one of the most flexible survey tools around, we get requests for customizations that are not available out of the box. This is where JavaScript and Custom Scripting can save the day. If you have scripting chops you can use the JavaScript action or the Custom Scripting action to achieve the survey of your dreams.


[article("bodfy")]

Want to use a future or past date dynamically in a survey? This script adds or subtracts time to/from the current date. 

See the script in action in an example survey

OR

Add a survey with this script and setup to your account.

Features and functions used in this script:

Copy and paste the script in a Custom Script Action that precedes the Hidden Value you wish to set.

Once this is set up you'll be able to use the merge code for that hidden action later on in your survey!

format = "Y-m-d"
now = strtotime(date(format)) + 172800
twodays = date('Y-m-d',now)

setvalue(3,twodays) -- 3 is the ID of the Hidden Value

Required Customizations

In the script above you will need to customize variables highlighted in yellow in order to make the script work in your survey.

  1. First, you will want to decide if you are adding or subtracting time. If you are subtracting, change the plus sign to a minus. 
  2. Next, decide how much time you'd like to add or subtract. Calculate that time into seconds and put that in place of 172800 (2 days in seconds). 
  3. To finish, change the 3 to the ID of the hidden value or question you wish to set.
