问题描述
我需要更改Woocommerce支付网关的名称，而不是在前端显示帽子（这可以在设置中轻松实现），而是Woo使用的内部标题。
例如，在class-wc-gateway-cheque.PHP中，我发现了这一点
$this->id = 'cheque';
，但仅在此处更改名称是无效的。我该如何更改Woocommerce内部使用的付款方式名称？
解决方法
因此，您可以做的是将源代码从WC_Gateway_Cheque Class 复制到插件文件，如下所述：
要基于现有的WooCommerce付款方式（如cheque来创建自定义网关，建议copy the source code from WC_Gateway_Cheque Class插入插件（根据您的需要调整代码）。
您可以将代码复制到您要命名的php文件中，例如wc-invoice-payments.php。
要复制的代码：

代码进入活动子主题（或活动主题）的functions.php文件中。经过测试，可以正常工作。
然后在管理员中启用 WooCommerce发票网关插件。
现在，在WooCommerce设置的付款部分中，您可以启用此付款网关。
您可以取消设置第一项功能的原始支票付款网关，将其设置为删除/删除：
add_filter( 'woocommerce_payment_gateways','wc_invoice_add_to_gateways' );
function wc_invoice_add_to_gateways( $gateways ) {
$gateways[] = 'WC_Invoice_Gateway';
unset($gateways['WC_Gateway_Cheque']; // Remove Cheque gateway
return $gateways;
}
它应该可以正常工作。

初始答案：
由于所有支付网关都扩展了WC_Payment_Gateway类，如果您look to get_title() method，您会看到可以使用过滤器挂钩woocommerce_gateway_title。
因此，对于"cheque"付款ID，您将按以下方式使用它：
add_filter( 'woocommerce_gateway_title','change_cheque_payment_gateway_title',100,2 );
function change_cheque_payment_gateway_title( $title,$payment_id ){
if( $payment_id === 'cheque' ) {
$title = __("Something else","woocommerce");
}
return $title;
}
