Setting a Custom Redirect
For some forms you build, you may wish to direct your site visitor to a specified URL instead of the Thank You Page after they submit the form. In order to do this, you must employ an override on the Form Folder.
Edit the Form Folder then click on the Overrides tab. Notice the first field at the top, labeled Custom Success Action.
If you read through the help text for the field you will notice that this field requires CMFFormController actions. However the help text does provide an example for setting a custom redirect.
Paste the following code into the field:
redirect_to:string:thanks-page
Where 'thanks-page' is the Short Name of the object you wish to point to after the form has been submitted. Keep in mind that simply indicating the short name may not be enough information - the string is looking for a relative URL, that is, a web address defined in relation to where the Form Folder is in your site's file structure. You can either use the "../../" method or use an absolute URL (i.e. http://www.mysite.org/forms/thanks-page).
