PHP添加符号，如果没有价格

有两种不同数量和价格的产品

    simple product -1 :         qty      price
                                 2        150
                                 3        145
                                 5        130
                                 10      100


    simple product -2 :         qty      price
                                 2        195
                                 5        175
                                 9        170

我想以以下格式显示数量和价格：

qty : 2          3          5       9         10

     $150       $145       $130      -        $100

     $195         -        $175     $170       -  

下面是显示价格和数量的代码

/*
$_tResult = [2, 3, 5, 9, 2, 5, 10]
*/


     /*
$_tierPrice value

当数组中没有价格值时，如何添加“-”代码中的主要逻辑错误是数组元素不等于上面的数字

您需要做的是创建一个数组，其中包含要显示的元素和键中的

[-]

试试这个：

<?php $_item->setData('tier_price',null); ?>
          <?php $_tierPrices = $this->getTierPrices($_item); ?>
          <?php //print_r($_tResult); ?>
          <?php foreach ($_tierPrices as $price): ?>
            <td>
               <?= (!empty($price['price'])) ? $price['formated_price']: "-"; ?>
            </td>    
           <?php endforeach; ?>

如果不起作用：

替换：

<?= (!empty($price['price_qty'])) ? $price['formated_price']: "-"; ?>
with
<?= (!empty($price['formated_price'])) ? $price['formated_price']: "-"; ?>

评论或编辑您的问题。告诉我们什么是输出：

$\u tierplices的值是多少？数组是什么样子的？$\u tierplices只是对代码的一个注释。打开和关闭PHP是一项繁重的操作，您不应该在循环中这样做。我建议您首先使用VTemplate这样的模板引擎，当您熟悉这个概念时，您可以开始使用smarty这样的更强大的引擎，因为您有额外的

else:

是一个打字错误吗？使用isset——在上面的代码中不起作用。您的代码输出看起来也和我上面提到的一样。谢谢。你们看了完整的答案了吗？试过不同的条件吗？

echo”的输出是什么；打印（价格）；回声“我得到的五个产品数组输出如下所示：数组（[price\u id]=>18[website\u id]=>0[all\u group]=>1[cust\u group]=>32000[price]=>150.0000[price\u qty]=>2[website\u price]=>150.0000[formatted\u price]=>150.00[savePercent]=>4[formatted\u price\u inclu tax]=>150.00美元）我刚才看到。。。您的阵列都没有空白价格。。。请在将数组放入foreach之前重新构造数组
