Overwrite Mage_Checkout_Block_Onepage_Payment class:

<blocks>
    <checkout>
        <rewrite>
            <onepage_payment>SR_MagentoCommunity_Block_Onepage_Payment</onepage_payment>
        </rewrite>
    </checkout>
</blocks>

app/code/local/SR/MagentoCommunity/Block/Onepage/Payment.php

<?php
class SR_MagentoCommunity_Block_Onepage_Payment extends Mage_Checkout_Block_Onepage_Payment
{
    /**
     * Retrieve is allow and show block
     *
     * @return bool
     */
    public function isShow()
    {
        if ($this->getGrandTotal() <= 0) {
            return false;
        }
        return true;
    }
    private function getGrandTotal()
    {
        return Mage::getSingleton('checkout/type_onepage')->getQuote()->getGrandTotal();
    }
}

最后，覆盖

skin/frontend/base/default/js/opcheckout.js

ShippingMethod.prototype.nextStep = function(transport){
    var response = transport.responseJSON || transport.responseText.evalJSON(true) || {};
    if (response.error) {
        alert(response.message.stripTags().toString());
        return false;
    }
    if (response.update_section) {
        $('checkout-'+response.update_section.name+'-load').update(response.update_section.html);
    }
    if (response.goto_section) {
        checkout.gotoSection(response.goto_section, true);
        checkout.reloadProgressBlock();
        return;
    }
    payment.initWhatIsCvvListeners();
    if (response.payment_methods_html) {
        $('checkout-payment-method-load').update(response.payment_methods_html);
    }
    checkout.setShippingMethod();
};
Review.prototype.save = function(){
    if (checkout.loadWaiting!=false) return;
    checkout.setLoadWaiting('review');
    if (!$('#co-payment-form')) {
        var params = 'method=free';
    } else {
        var params = Form.serialize(payment.form);
    }

    if (this.agreementsForm) {
        params += '&'+Form.serialize(this.agreementsForm);
    }
    params.save = true;
    new Ajax.Request(
        this.saveUrl,
        {
            method:'post',
            parameters:params,
            onComplete: this.onComplete,
            onSuccess: this.onSave,
            onFailure: checkout.ajaxFailure.bind(checkout)
        }
    );
};

[Update]

How you overwrite opcheckout.js?

skin/frontend/base/default/js/rewriteopcheckout.js

ShippingMethod.prototype.nextStep = function(transport){
    var response = transport.responseJSON || transport.responseText.evalJSON(true) || {};
    if (response.error) {
        alert(response.message.stripTags().toString());
        return false;
    }
    if (response.update_section) {
        $('checkout-'+response.update_section.name+'-load').update(response.update_section.html);
    }
    if (response.goto_section) {
        checkout.gotoSection(response.goto_section, true);
        checkout.reloadProgressBlock();
        return;
    }
    payment.initWhatIsCvvListeners();
    if (response.payment_methods_html) {
        $('checkout-payment-method-load').update(response.payment_methods_html);
    }
    checkout.setShippingMethod();
};
Review.prototype.save = function(){
    if (checkout.loadWaiting!=false) return;
    checkout.setLoadWaiting('review');
    if (!$('#co-payment-form')) {
        var params = 'method=free';
    } else {
        var params = Form.serialize(payment.form);
    }

    if (this.agreementsForm) {
        params += '&'+Form.serialize(this.agreementsForm);
    }
    params.save = true;
    new Ajax.Request(
        this.saveUrl,
        {
            method:'post',
            parameters:params,
            onComplete: this.onComplete,
            onSuccess: this.onSave,
            onFailure: checkout.ajaxFailure.bind(checkout)
        }
    );
};

现在打开 checkout/onepage.phtml   当前主题中的模板.防爆.我的情况是默认的 rwd/default

app/design/frontend/rwd/default/template/checkout/onepage.phtml

添加以下行：

<script type="text/javascript" src="<?php echo $this->getSkinUrl('js/rewriteopcheckout.js') ?>"></script>

我已经使用带有样本数据的全新安装测试了M1.9.4.1。

上述问题的受影响文件是

{Magento-Root-Folder}/app/design/frontend/{YourTheme}/default/template/checkout/onepage/payment/methods.phtml

请注意，如果模板文件夹中没有"checkout"文件夹，请务必从 {Magento-Root-Folder}/app/design/frontend/base/default/template/checkout复制它   到您的模板文件夹; 确保你保持结构相同

在这个文件（methods.phtml）中我们实际查看了可用的付款（第45行），这是我们需要调整一点的地方。

1）将此行放在文件顶部的任意位置以获取当前报价数据（我们将在步骤2中使用它）

$quote_data = Mage::helper('checkout')->getQuote()->getData();

它将包含 $quote_data[grand_total]

2）搜索围绕第45行迭代的付款方式

foreach ($methods as $_method):
    $_code = $_method->getCode();

我们需要检查$ _code（'free'表示zero Subtotal Checkout）并在同一个foreach中添加一个简单的if子句：

if ($_code == "free" && $quote_data[grand_total] < 1) { // if payment method is free and grand total '0'
    // this is where your action should happen
    $class_show_pm = ""; // will be used to show/hide 'dt' tag
    $radio_checked = "checked"; // will be used to enable/disable radio button
    $radio_onclick = "payment.switchMethod(" .$_code .")"; // will be used to load js code
} else {
    $class_show_pm = "none";
    $radio_checked = "";
    $radio_onclick = "";
}
