add_action( 'gform_after_delete_field', 'your_custom_function', 10, 2 );
Then define your custom function:
function your_custom_function( $form_id, $field_id ) { // your custom code here return $form_id; }
Parameters
$form_id
(integer): The ID of the current form.$field_id
(integer): The ID of the deleted field.

You can find additional details on the Gravity Forms documentation for gform_after_delete_field. This action hook is located in the GFFormsModel::delete_field() function in form_model.php.
Examples
Logging Deletions
This example logs every time a field is deleted, recording the username, form ID, and field ID in a log file.
add_action( 'gform_after_delete_field', 'log_deleted_field', 10, 2 ); function log_deleted_field( $form_id, $field_id ) { // File to record deletions $log_file = ABSPATH . '/gf_deleted_fields.log'; // Open the log file for appending $f = fopen( $log_file, 'a' ); // Get the current user $user = wp_get_current_user(); // Write the log entry fwrite( $f, date( 'c' ) . " - Field deleted by {$user->user_login}. Form ID: {$form_id}. Field ID: {$field_id}\n" ); // Close the log file fclose( $f ); }
In this example, we use the wp_get_current_user()
function to retrieve the current user’s information, and then write it to a log file with the form ID and field ID whenever a field is deleted. The log file is stored in the root directory of your WordPress installation.
