Question

我想在我的woocommerce插件中获得购物车的总价。

我想把它作为一个浮点数来得到它：21.00但我不知道如何得到它。我的代码输出了奇怪的结果，这是我的确切代码：

$total         = $woocommerce->cart->get_total();
$total_a       = WC()->cart->get_total();
$total1        = $woocommerce->cart->get_total_ex_tax();
$total1_a      = WC()->cart->get_total_ex_tax();
$total2        = $woocommerce->cart->get_cart_total();
$total2_a      = WC()->cart->get_cart_total();

输出：

0,00 €
0,00 €
0,00 €
0,00 €
21,00 €
21,00 €

如果我从string转换为float，结果当然是0.00。

如何以浮点数的形式获得购物车总数的任何帮助？

Answer 1

直接访问total属性，它是公开的：

global $woocommerce;
echo $woocommerce->cart->total;

/** The set of delimiters (ordering does not matter). */
val delimiters = new scala.collection.mutable.HashSet[String]

private lazy val _delim: Parser[Token] = {
    // construct parser for delimiters by |'ing together the parsers for the individual delimiters,
    // starting with the longest one -- otherwise a delimiter D will never be matched if there is
    // another delimiter that is a prefix of D
    def parseDelim(s: String): Parser[Token] = accept(s.toList) ^^ { x => Keyword(s) }

    val d = new Array[String](delimiters.size)
    delimiters.copyToArray(d, 0)
    scala.util.Sorting.quickSort(d)
    (d.toList map parseDelim).foldRight(failure("no matching delimiter"): Parser[Token])((x, y) => y | x)
}
protected def delim: Parser[Token] = _delim
}

您还可以根据您的要求在浮动值中转换$ amount。

Answer 3

我有这样的代码并且工作得很完美：

if ( ! WC()->cart->prices_include_tax ) {
    $amount = WC()->cart->cart_contents_total;
} else {
    $amount = WC()->cart->cart_contents_total + WC()->cart->tax_total;
}

祝你好运！

Answer 4

尝试一下 WC（）->购物车-> cart_contents_total

Answer 5

在2020年推出Woocommerce 4 +

$total_cart = WC()->cart->get_displayed_subtotal(); // without taxs and shipping fees
echo $total_cart; // ex: 0.00

Answer 6

最好的方法是使用 get_total()，同时传递默认值“view”以外的上下文。当上下文被查看时，价格将被格式化以供显示。当设置为其他任何值时，它将传回原始值。

示例：

WC()->cart->get_total( 'raw' );

还值得注意的是，$woocommerce（当然前提是您访问了全局第一个）与WC() 完全相同。我建议尽可能使用 WC()。

Answer 7

global $woocommerce;
$woocommerce->cart->cart_contents_total (Cart total)
$woocommerce->cart->tax_total (tax total)
$woocommerce->cart->shipping_total (shipping total)

Answer 8

它有一些方法，您不需要从属性中获取它们。

使用：$.ajax( { type:'GET', url:'api', dataType: 'json', success: function(data){ console.log(data); for (var i=0; i<data.length; i++) { var row = $( '<tr>' + '<td>' + data[i].id + '</td>' + '<td>' + data[i].name + '</td>' + '<td>' + ' <button onclick="editItem(ID)">EDIT</button>' + ' <button onclick="deleteItem(ID)">DELETE</button>' + '</td>' + '</tr>' ); $('#my_table').append(row); } } } );

代替：WC()->cart->get_cart_contents_total()

并使用：WC()->cart->cart_contents_total

代替：WC()->cart->get_taxes_total()

Answer 9

Woocommerce 4.8 WC()->cart->total 工作正常，虽然我有点担心在没有 getter 帮助的情况下获得这个值，但它现在似乎是最简单的方法。
