向数组添加默认值

I have the following code in my opencart product.php control file.

我在opencart product.php控制文件中有以下代码。

$product_option_value_data = array();

        foreach ($product_option['product_option_value'] as $product_option_value) {
            $product_option_value_data[] = array(
                'product_option_value_id' => $product_option_value['product_option_value_id'],
                'option_value_id'         => $product_option_value['option_value_id'],
                'quantity'                => isset ($product_option_value['quantity']) ? $product_option_value['quantity'] : '1',
                'subtract'                => $product_option_value['subtract'],
                'price'                   => isset ($product_option_value['price'])? $product_option_value['price'] : '27.99',
                'price_prefix'            => $product_option_value['price_prefix'],
                'points'                  => $product_option_value['points'],
                'points_prefix'           => $product_option_value['points_prefix'],                        
                'weight'                  => $product_option_value['weight'],
                'weight_prefix'           => $product_option_value['weight_prefix'] 
            );
        }

I need to add default value to quantity, price, subtract. Any help will be highly appreciated.

我需要为数量，价格，减去添加默认值。任何帮助将受到高度赞赏。

You are almost there. You have done that for two of your elements. Just add the same check for the subtract one.

你快到了。你已经为你的两个元素做了这个。只需为减去一个添加相同的检查。

$product_option_value_data = array();
    foreach ($product_option['product_option_value'] as $product_option_value) {
        $product_option_value_data[] = array(
            'product_option_value_id' => $product_option_value['product_option_value_id'],
            'option_value_id'         => $product_option_value['option_value_id'],
            'quantity'                => 
                   isset ($product_option_value['quantity']) ?
                          $product_option_value['quantity'] :
                          '1', // THE DEFAULT FOR QUANTITY
            'subtract'                =>  
                    isset ($product_option_value['subtract']) ? 
                           $product_option_value['subtract'] :
                           '22', // THE DEFAULT FOR SUBTRACK
            'price'                   => 
                    isset ($product_option_value['price']) ? 
                           $product_option_value['price'] : 
                           '27.99', //THE DEFAULT FOR PRICE
            'price_prefix'            => $product_option_value['price_prefix'],
            'points'                  => $product_option_value['points'],
            'points_prefix'           => $product_option_value['points_prefix'],                        
            'weight'                  => $product_option_value['weight'],
            'weight_prefix'           => $product_option_value['weight_prefix'] 
        );
    }

Hope this helps
