If you would like to save the url of the site that the user came from, you can use this code. This will only work if you also go to the Formidable -> global settings page and turn on user tracking.

You may have the need to create a custom field with the data format saved differently than Formidable saves by default. This is a common with saving date fields in a different format and saving the image url for a file upload field instead of the id. When using this custom code the custom field name should not be included in your post settings for this form.

Use the code below to prevent entries from embedded forms and repeating sections from being deleted when the parent entry is deleted. This will automatically apply to all embedded forms and repeating sections in the form.
