I have the snippet to change the woocommerce order status field from pending to completed, which I will post below.This woks fine. My problem is that I now have a second product that uses different form, with the same woocommerce status field that needs to to be triggered to "completed" after payment. If I simply add a copy of the snippet with different form and field id's, it crashes the site. I imagine there must be code to update this status field for sites with multiple forms and multiple products that use the same payment gateway.  Any advice greatly appreciated!  

add_action( 'woocommerce_order_status_completed', 'update_frm_entry_after_wc_order_completed' );

function update_frm_entry_after_wc_order_completed( $order_id ) {

                $order = new WC_Order( $order_id );

                $items = $order->get_items();

                foreach ( $items as $item_id => $product ) {

                               if ( isset( $product['formidable_form_data'] ) && is_numeric( $product['formidable_form_data'] ) ) {

                                               $entry_id = $product['formidable_form_data'];

                                               $entry = FrmEntry::getOne( $entry_id );

                                               if ( $entry && $entry->form_id == 73 ) {

                                                               $field_id = 1651;//Replace  with the field ID to update

                                                               $new_value = 'Complete';

                                                               FrmEntryMeta::update_entry_meta( $entry_id, $field_id, null, $new_value );

                                               }

                               }

                }

}

BTW the second form id is 78, and the field id is 1720
