• fm_form_submission – Use this for a custom submission action. Run after a form has been submitted. The action is passed a single argument, which is an associative array with two keys:
    • form –  an array containing information about the form structure
    • data –  an array containing the submission data. If any form items have nicknames, these nicknames will be used as keys in this array.
  • fm_control_types (filter) – Use this to add your own form controls. This is passed an array of control types. Keys are a ‘sanitized’ slug for the control type, values are a class name for the control object. The comments in types/base.php will help you in creating a custom control.
