PHP添加符號，如果沒有價格

Question

有兩種產品具有不同的數量和價格

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


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

我要表現在以下格式的數量和價格：

qty : 2   3   5  9   10 

    $150  $145  $130  -  $100 

    $195   -  $175  $170  - 

下面是代碼顯示價格和數量

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


    /* 
$_tierPrice value

<?php $_item->setData('tier_price',null); ?> 
      <?php $_tierPrices = $this->getTierPrices($_item); ?> 
      <?php //print_r($_tResult); ?> 
      <?php foreach ($_tierPrices as $price): ?> 
        <td> 
         <?php if(in_array($price['price_qty'],$_tResult)) :?>

           <?php echo "-"; ?> 
         <?php endif; ?> 
        </td>

下面是代碼的實際輸出。

qty :  2   3   5  9   10 

     $150  $145  $130 $100 

     $195  $175  $170  

如何添加「 - 」當有數組

Answer 1

主要邏輯錯誤在你的代碼中沒有價格值，是該數組元素不等於上述數字。

您需要做的是在要顯示的鍵中創建一個包含元素和[-]的數組。

Answer 2

試試這個：

<?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; ?> 

如果它不工作：

替換：

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

評論或編輯你的問題。告訴我們什麼是輸出：

echo "<pre>"; print_r($price); echo "</pre>";
