Php 根据产品变更条款向Woocommerce电子邮件通知添加收件人

我创建了一个Woocommerce插件，并要求它做两件事：

根据购物车中的产品变体向特定电子邮件地址发送通知消息

电子邮件必须仅包含相关产品，而不包含其他属性的产品

例如：

产品A有一个名为Chef的属性，其中Chef one和Chef two是变量项。用户可以从厨师一号或厨师二号中选择产品A

如果用户从chef one中选择产品A，则必须向发送通知电子邮件chefone@email.com包含所订购产品的名称（它将显示在定期的Woocommerce通知电子邮件中）

如果用户从厨师一号选择产品A，从厨师二号选择产品B，则必须向厨师一号发送只包含产品A的通知电子邮件，向厨师二号发送只包含产品B的通知电子邮件

我已经使用上的教程创建了插件，并对其进行了调整，以满足上述目的

我还修改了代码，找到了以下解决方案：

以下是我的插件类文件中的代码：

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

        )
    );
}

这是我能得到的最接近的，但它不起作用。我怀疑问题出在“根据产品属性术语确定发送到哪个电子邮件地址”这句话的周围。插件一直在加载，直到我添加了那个部分

该函数应该在一个单独的插件文件中吗

我还需要帮助，使电子邮件中只包含与发送给的供应商相关的信息

任何帮助这个插件工作将不胜感激

WooCommerce（或您的代码）中不存在新订单的筛选器

正确的过滤器挂钩（位于类别核心代码第269行）如下所示：

$recipient  = apply_filters( 'woocommerce_email_recipient_' . $this->id, $this->recipient, $this->object );

在这个钩子中，

$this->id

是您的“

新订单”

您的代码中存在较大错误：


术语名称应该类似于
“one”
或
“chef one”
，，但绝对不是
“pa_chef-one”
，因为
“pa_chef”是属性“chef”的分类标准

多个电子邮件收件人不在一个数组中，而是在一个分隔的字符串中

因此，正确的代码应该是：

add_filter( 'woocommerce_email_recipient_new_order', 'add_recipient', 10, 2 );
function add_recipient( $recipient, $order )
{
    if ( ! is_a( $order, 'WC_Order' ) ) return $recipient;

    // Additional email recipient
    $additional_email = "info@email.com";

    // The term name "pa_chef-one" is very strange … It should be "one" or "chef-one" (may be)
    $term_slug = "one";

    $has_term = false;

    // Iterating through each order item
    foreach ($order->get_items() as $item_id => $item_obj) {
        $variation_id = $item_obj->get_variation_id();
        $variation_obj = wc_get_product($variation_id);
        $variation_attributes = $variation_obj->get_attributes();
        foreach( $variation_attributes as $taxonomy_key => $term_value ){

            if( $taxonomy_key == "pa_chef" && $term_value == $term_slug ){
                $recipient .= ','. $additional_email;
                $has_term = true;
                break; // stop the 2nd loop
            }
        }
        if( $has_term ) break; // stop the 1st loop
    }
    return $recipient;
}

代码位于活动子主题（或主题）的function.php文件或任何插件文件中

类似的答案：



我已在回答中更新了代码……感谢@LoicTheAztec对代码的反馈和改进。我已经将上面的代码片段添加到插件的类文件中，在“确定发送到哪个电子邮件地址”和“return$email；”这两行下面，当我激活插件时仍然收到一个错误。“返回$recipient；”是否替换“$email”功能？这是我的第一个插件，因此我可能需要一定的尝试和错误。@CraigdeGouveia我不完全确定我的代码是否100%，但钩子是正确的。函数中的参数是正确的。（我在最后的答案中用这个钩子添加了一些旧答案的工作参考…）。我已经测试了foreach循环周围的所有代码，它也可以工作。现在问题可能出在您将在此函数中设置的术语名称或slug中。问题也可能在其他地方。我希望你能找到路。但是这里的主要问题是关于钩子的，这个钩子就是这个问题的女仆。
