如何添加多分区数组的值？ [英] How to add the values of multi-deminsional array?

问题描述

我使用CODEIGNITER购物车类。以下是购物车内容的 VAR_DUMP 。我有一个无线电选择字段，允许您选择 SHIP 选项。问题是，我的PHP没有得到 SHIP 值，但只返回购物车值中的最后一个项目，乘以购物车项目的总数。如何从每个项目中获取 SHIP 数组并对值进行求和？

I'm using CODEIGNITER Cart Class. The following is a VAR_DUMP of the cart contents. I have a radio selection field which allows you to select a SHIP option. The problem is that my PHP is not getting the SHIP values but only returning the last item in cart's value and multiplying by the total number of cart items. How do I get the SHIP array from each item and sum the values?

$ship_array = $this->cart->ship($item['rowid']); 
foreach ($ship_array as $index => $ship_option){
        #SHIPPING CALC

        $ship_total = 0;

        foreach ($cart as $item)
        {
         $ship_total += $ship_option;
        }

echo '<label><input type="radio" name="print" class="option" data-number="'. $ship_total .'" value="'. $index .'"/> UPS '. $index .' </label> '; }

^此代码只能从 ship 在购物车的最后一项。结果将表明 ground 运费是$ 43.35（14.45（地运价值* 3总项）

^this code will only get the values from ship in the last item in the cart. The result will say that ground shipping is $43.35 (14.45 (ground shipping value * 3 total items)

是错误的，我需要从每个 $ item

Obviously this is wrong i need to add the shipping values from each $item

推荐答案

您可以尝试

$array = array(     
'554ed09a5f80917741359cc9da50a75c' => array('rowid' => '554ed09a5f80917741359cc9da50a75c','id' => '101','qty' => '1','price' => '112.5','name' => 'Business Card','ship' => array('Ground' => 9.73,'2nd Day Air' => 18.54,'Overnight' => 26.27),'options' => array('Pr Package' => 'Pro','Design Package' => 'Premium','subtotal' => 112.5)),
'675d8a197a25e6720af7ac05707fee40' => array('rowid' => '675d8a197a25e6720af7ac05707fee40','id' => '102','qty' => '1','price' => '446','name' => 'Booklet','ship' => array('Ground' => 14.45,'2nd Day Air' => 22.57,'Overnight' => 34.12),'options' => array('Pr Package' => 'Plus','Design Package' => 'Ultimate','subtotal' => 446)),
'aea5d2f84151e65a0a1e50371aad26aa' => array('rowid' => 'aea5d2f84151e65a0a1e50371aad26aa','id' => '102','qty' => '1','price' => '325','name' => 'Booklet','ship' => array('Ground' => 14.45,'2nd Day Air' => 22.57,'Overnight' => 34.12),'options' => array('Pr Package' => 'Pro','Design Package' => 'Premium','subtotal' => 325)));


$shipArray = $array ; // Replace with $this->cart->ship($item['rowid']);
$shipTotal = array("prize"=>0,"ground"=>0,"air"=>0,"overnight"=>"0");
foreach ($shipArray as $index => $shipOption){
    $shipTotal['prize'] += $shipOption['qty'] * $shipOption['price'];
    $shipTotal['ground'] += $shipOption['ship']['Ground'];
    $shipTotal['air'] += $shipOption['ship']['2nd Day Air'];
    $shipTotal['overnight'] += $shipOption['ship']['Overnight'];
}

var_dump($shipTotal);

输出

array
  'prize' => float 883.5
  'ground' => float 38.63
  'air' => float 63.68
  'overnight' => float 94.51
