根据尺寸自定义Woocommerce产品重量计算 [英] Custom Woocommerce product weight calculation from dimensions

问题描述

在向woocommerce商店添加产品时，我会设置重量(以千克为单位)和尺寸(以厘米为单位).如果[(高度x长度x宽度)/5000]高于实际重量，那么我希望以此来计算运费.

When adding products to my woocommerce store I set weight (in kg) and dimensions (in cm). If [(Height x Length x Width) / 5000] is higher than actual weight then I want this to be used to calculate shipping.

我认为我可以使用过滤器来操纵$ weight，但是没有成功.这是我的代码:

I thought I could use a filter to manipulate $weight but with no success. Here is my code:

function woocommerce_product_get_weight_from_dimensions( $weight ) {
    global $product;
    $product = wc_get_product( id );
    $prlength = $product->get_length();
    $prwidth = $product->get_width();
    $prheight = $product->get_height();
    $dimensions = $prlength * $prwidth * $prheight;
    $dweight = $dimensions / 5000;
    if ($dweight > $weight) {
        return $dweight;
    }
    return $weight;
}
add_filter('woocommerce_product_get_weight', 'woocommerce_product_get_weight_from_dimensions');

我在做什么错了?

推荐答案

$ product = wc_get_product(id); 出现错误，因为 id 应该是定义的变量，例如 $ id .

There is an error with $product = wc_get_product( id ); as id should be a defined variable like $id instead.

此外，在挂钩函数中，WC_Product对象已经是缺少的可用参数.

Also the WC_Product object is already a missing available argument in your hooked function.

最后，我重新审视了您的代码，使其更加紧凑:

Finally, I have revisited your code making it more compact:

add_filter( 'woocommerce_product_get_weight', 'custom_get_weight_from_dimensions', 10, 2 );
function custom_get_weight_from_dimensions( $weight, $product ) {
    $dim_weight = $product->get_length() * $product->get_width() * $product->get_height() / 5000;
    return $dim_weight > $weight ? $dim_weight : $weight;
}

代码会出现在您活动的子主题(或主题)的function.php文件中，也可能会出现在任何插件文件中.

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

此代码已经过测试并且可以正常工作.

This code is tested and works.
