您好，我有这段代码，显示 woocomerce 产品的价格和重量，并计算总重量，我只想在产品有重量的情况下打印重量。
// shows the total price and total weight based on the quantity entered
add_action( 'woocommerce_single_product_summary', 'show_total_price_and_total_weight_by_quantity', 31 );
function show_total_price_and_total_weight_by_quantity() {
// create the divs that will contain the total price and total weight
echo sprintf('<div id="product_total_price" style="display:none;margin-bottom:20px;">%s %s</div>', __('Total:','woocommerce'),'<span class="price"></span>');
echo sprintf('<div id="product_total_weight" style="display:none;margin-bottom:20px;">%s %s</div>', __('Área:','woocommerce'),'<span class="weight"></span>');
}
// change the total price and total weight based on the quantity entered
add_action( 'wp_footer', 'change_total_price_and_total_weight_by_quantity', 99 );
function change_total_price_and_total_weight_by_quantity() {
// only on the product page
if ( ! is_product() ) {
return;
}
global $product;
// initializes the array that will contain the product data
$product_data = array();
// do divs need to be shown?
$show = true;
// gets the currency and unit of weight
//
$currency = get_woocommerce_currency_symbol();
$weight_unit = 'm²';
// if the product is simple
if ( $product->is_type( 'simple' ) ) {
// set the type of product
$product_data['type'] = 'simple';
// get simple product data
$product_data['price'] = $product->get_price();
$product_data['currency'] = $currency;
$product_data['weight'] = $product->get_weight();
$product_data['weight_unit'] = $weight_unit;
}
// if the product is variable
if ( $product->is_type( 'variable' ) ) {
// set the type of product
$product_data['type'] = 'variable';
// get the ids of the product variations
$variation_ids = $product->get_children();
foreach ( $variation_ids as $variation_id ) {
// gets the object of the variation product
$variation = wc_get_product( $variation_id );
// gets product variation data
$product_data['variation'][$variation_id]['price'] = $variation->get_price();
$product_data['variation'][$variation_id]['currency'] = $currency;
$product_data['variation'][$variation_id]['weight'] = $variation->get_weight();
$product_data['variation'][$variation_id]['weight_unit'] = $weight_unit;
}
// hides the div
$show = false;
}
// returns the JSON representation of a data
$product_data_json = json_encode( $product_data );
?>
<script>
jQuery(function($) {
// create a javascript object with product data
<?php
echo "var productData = ". $product_data_json . ";";
if ( $show ) {
?>
var product_total = parseFloat( productData.price * $('[name=quantity]').val());
$('#product_total_price .price').html( productData.currency + product_total.toFixed(2) );
var weight_total = parseFloat(productData.weight * $('[name=quantity]').val());
$('#product_total_weight .weight').html( weight_total.toFixed(2) + ' ' + productData.weight_unit);
$('#product_total_price').show();
$('#product_total_weight').show();
<?php
}
?>
// when the quantity is changed or a product option is selected
jQuery('[name=quantity], table.variations select').on('change',function(){
// shows data based on product type
switch( productData.type ) {
case 'simple':
// update the fields
var product_total = parseFloat(productData.price * $(this).val());
$('#product_total_price .price').html( productData.currency + product_total.toFixed(2) );
var weight_total = parseFloat(productData.weight * $(this).val());
$('#product_total_weight .weight').html( weight_total.toFixed(2) + ' ' + productData.weight_unit);
break;
case 'variable':
// gets the id variation based on the options chosen
var variation_id = $('input.variation_id').val();
// if the variation id is valid and the current option is different from "Choose an option"
if ( parseInt( $('input.variation_id').val() ) > 0 && $('input.variation_id').val() != '' && $(this).find('option').filter(':selected').val() != '' ) {
$('#product_total_price').show();
$('#product_total_weight').show();
// gets the object based on the selected variation
var obj = productData.variation[variation_id];
// update the fields
var product_total = parseFloat(obj.price * $(this).val());
$('#product_total_price .price').html( obj.currency + ' ' + product_total.toFixed(2) );
var weight_total = parseFloat(obj.weight * $(this).val());
$('#product_total_weight .weight').html( weight_total.toFixed(2) + ' ' + obj.weight_unit);
// otherwise it hides the divs
} else {
$('#product_total_price').hide();
$('#product_total_weight').hide();
}
break;
}
});
});
</script>
<?php
}
如果产品没有重量我不需要执行，这是为了 woocomerce。
谢谢！
我尝试了多个 if 条件，但都破坏了代码。

没有重量的产品不显示重量。
