Please do not remove the question saying that it's woocommerce.
In the code below there is $fields = wp_parse_args( $fields, apply_filters( 'woocommerce_credit_card_form_fields', $default_fields, $this->id ) );
so i believe that i can modify $default_fields by add_filter
/**
* Output field name HTML
*
* Gateways which support tokenization do not require names - we don't want the data to post to the server.
*
* @since 2.6.0
* @param string $name Field name.
* @return string
*/
public function field_name( $name ) {
return $this->supports( 'tokenization' ) ? '' : ' name="' . esc_attr( $this->id . '-' . $name ) . '" ';
}
/**

* @since 2.6.0
*/
public function form() {
wp_enqueue_script( 'wc-credit-card-form' );
$fields = array();
$cvc_field = '<p class="form-row form-row-last">

$fields = wp_parse_args( $fields, apply_filters( 'woocommerce_credit_card_form_fields', $default_fields, $this->id ) );
?>
<fieldset id="wc-<?php echo esc_attr( $this->id ); ?>-cc-form" class='wc-credit-card-form wc-payment-form'>

But i am unable to do it. This is what i tried within the extended class
add_filter( 'woocommerce_credit_card_form_fields', 'ggowl_auth_creditform', $priority = 10, $accepted_args = 1 );
public function ggowlwoo_field_name( $name ) {

Reset to default 0To add a filter of a class's method you must use an array in the callback like this:
add_filter( 'woocommerce_credit_card_form_fields', array( $this, 'ggowl_auth_creditform' ), 10, 1 );. Of course that method must be public and either static, or the object must be instantiated.
