php - 如何从 Woocommerce 订单总额中删除“$”

问题描述

我无法从 Woocommerce Cart Total 中获取美元符号来剥离价值

我已经尝试了以下代码的所有变体并将其添加到我的 email-order-details.php 文件中。没有一个能正常工作。$totalVal 要么保留美元符号，要么 $totalVal 打印为 0。当 $totalVal 打印为 0 时，我的 if 语句仍然打印。无论 if 比较器如何，它都会打印。我正在将更改实际上传到网络服务器并重新发送电子邮件。我可以让它在 test.php 文件中工作。好吧，我可以让它不回应声明，但我不能让它去掉美元符号。

<div><?php
        $strpTotal = $total['value'];
        $totalVal = floatval(ltrim($strpTotal, "$"));
        if ( $totalVal < 100 ){
                        echo 'My Text';}
                     ?></div>


<div><?php 
        $strpTotal = trim($total['value'], "$");
        if ( $strpTotal < 100 ){
                        echo 'My Text';}
                ?></div>


<div><?php 
        $strpTotal = $total['value'];
        $totalVal = trim($strpTotal, "$");
        if ( $totalVal < 100 ){
                        echo 'My Text';}
                ?></div>

整个文件代码如下

<?php
/**
 * Order details table shown in emails.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/emails/email-order-details.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce/Templates/Emails
 * @version 3.3.1

                ?></div>

</div>

<?php do_action( 'woocommerce_email_after_order_table', $order, $sent_to_admin, $plain_text, $email ); ?>

我想在我的 woocommerce 电子邮件中有条件 PHP if 语句。我的代码应该得到购物车的总数并从中扣除 $。然后比较它并确保购物车总数小于 100，如果总数小于 100，我的声明应该被打印出来。请所有帮助表示赞赏。
