Question

我在prestashop上有以下代码。我试图将{$ combination.price}减少20％。但最后更改阵列似乎不起作用？即{$ combination.price / 1.2）

任何人都可以帮助我，我如何能够以20％的价格回报价格？

{if isset($groups)}
// Combinations
{foreach from=$combinations key=idCombination item=combination}
    var specific_price_combination = new Array();
    var available_date = new Array();
    specific_price_combination['reduction_percent'] = {if $combination.specific_price AND $combination.specific_price.reduction AND $combination.specific_price.reduction_type == 

'percentage'}{$combination.specific_price.reduction*100}{else}0{/if};
    specific_price_combination['reduction_price'] = {if $combination.specific_price AND $combination.specific_price.reduction AND $combination.specific_price.reduction_type == 

'amount'}{$combination.specific_price.reduction}{else}0{/if};
    specific_price_combination['price'] = {if $combination.specific_price AND $combination.specific_price.price}{$combination.specific_price.price}{else}0{/if};
    specific_price_combination['reduction_type'] = '{if $combination.specific_price}{$combination.specific_price.reduction_type}{/if}';
    specific_price_combination['id_product_attribute'] = {if $combination.specific_price}{$combination.specific_price.id_product_attribute|intval}{else}0{/if};
    available_date['date'] = '{$combination.available_date}';
    available_date['date_formatted'] = '{dateFormat date=$combination.available_date full=false}';
    addCombination({$idCombination|intval}, new Array({$combination.list}), {$combination.quantity}, {$combination.price}, {$combination.ecotax}, {$combination.id_image}, 

 '{$combination.reference|addslashes}', {$combination.unit_impact}, {$combination.minimal_quantity}, available_date, specific_price_combination);
    {/foreach}

{/if}

Answer 1

$price * 0.8或$price - ( $price * 0.2 )无论哪种方式，他们都有相同的最终结果。第一个是变量$ price乘以80％，即20％赤字的价格。第二个例子是变量$ price减去变量$ price乘以20％，假设你用你试图以20％赤字返回的实际变量替换$ price，价格减去价格的20％。

减少数组中的值不起作用
