在 WooCommerce 中更改特定的支付网关标题

Question

我需要更改 Woocommerce 支付网关名称，而不是显示在前端的那些帽子（这可以在设置中轻松实现）而是 Woo 使用的内部标题。

以 class-wc-gateway-cheque.php 为例，我发现了这个

        $this->id  = 'cheque';

但只是在那里更改名称不起作用。如何更改 Woocommerce 内部为此付款方式使用的名称？

Answer 1

因此，您可以将源代码从WC_Gateway_Cheque Class 复制到插件文件，如下所述：

要基于现有的WooCommerce 支付方式cheque 制作自定义网关，建议在插件中使用copy the source code from WC_Gateway_Cheque Class（根据您的需要调整代码）。

您可以将代码复制到您将命名的 php 文件中，例如 wc-invoice-payments.php。

要复制的代码：

代码在您的活动子主题（或活动主题）的functions.php 文件中。经过测试并且可以工作。

然后在管理员中启用 WooCommerce Invoice Gateway 插件。
现在在 WooCommerce 设置的支付部分，您可以启用此支付网关。

您可以取消设置/删除原来的支票支付网关更改第一个功能，如：

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;
}

它应该按预期工作。

初步答案：

由于所有支付网关都扩展了 WC_Payment_Gateway 类，如果您look to get_title() method，您将看到您可以使用过滤器挂钩woocommerce_gateway_title。

所以对于"cheque"支付ID，你将使用它如下：

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;
}
