caldera_forms_mailer

Caldera Forms Banner

Runs before main mailer sends an email. The variable $mail has a keys for “recipients”, “headers”, “message”, “attachments” and “subject”.

The variable $data has all entry data that can be used in the email.

Note: In Caldera Forms 1.3.5 and later, if this filter does not return an array, it aborts sending the email. This makes this an excellent hooks for two uses:

  1. Sending mail data to an alternative email service to avoid phpmailer.
  2. Using this hook for easy access to entry data to do something besides send an email.

This filter exposes 4 parameters:

  • $mail The configuration for the email
  • $data The form entry data as an array
  • $form The form configuration
  • $entryid The entry ID — added in Caldera Forms 1.5.0.10

This example below shows how to add an extra recipient to the email:

This example shows how to customize the email message from the mailer tab:

 

In this next example, a Caldera Form field value is written to a file and then attached to the email. This illustrates both how to copy a field value to file, as well as how to add attachments to the Caldera Forms Email.
