在Woocommerce 3中为产品设置最小默认权重

Question

I'm trying to add a default product shipping weight to WooCommerce in my functions.php file but is not working, I'm not sure if I'm using the right snippets or missing parts of the snippet.

Here's that I'm using,

add_filter('woocommerce_product_get_weight', 'woocommerce_product_get_weight_filter');

function woocommerce_product_get_weight_filter($weight) {
  $default_weight = 0.1; 
  if ((!is_numeric($weight)) || ($weight <= 0.001)) {
    return $default_weight;
  }
  return $weight;
}

Answer 1

Try with empty() and the hook for product variations :

add_filter('woocommerce_product_variation_get_weight', 'woocommerce_product_get_weight_filter', 10, 2 );
add_filter('woocommerce_product_get_weight', 'woocommerce_product_get_weight_filter', 10, 2 );
function woocommerce_product_get_weight_filter( $weight, $product ) {
    if ( empty($weight) || $weight <= 0.001 ) {
        return 0.1;
    }
    return $weight;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

This will not work in admin product edit pages in the weight setting field. The only available hooks are working for "view" context and not in "edit" context (as in backend)…
