我需要將轉(zhuǎn)換代碼添加到order-confirmation.tpl模板中。但是，如果變量名稱中包含下劃線（也許我只嘗試幾個）字符，則輸出為空array（）。例如：{$order.details.payment} <- this works{$order.details.id_customer} <- this do NOT works{$order.details.total_paid_tax_incl} <- this do NOT works also我的目標(biāo)是將產(chǎn)品的總價格輸出到template($order.details.total_paid_tax_incl} 任何建議？有這個問題的經(jīng)驗嗎？我嘗試打印輸出，{$order.details}所以所有數(shù)據(jù)都應(yīng)該在這里。輸出： PrestaShop\PrestaShop\Adapter\Presenter\Order\OrderDetailLazyArray Object(    [order:PrestaShop\PrestaShop\Adapter\Presenter\Order\OrderDetailLazyArray:private] =&gt; Order Object        (            [id_address_delivery] =&gt; 21013            [id_address_invoice] =&gt; 21013            [id_shop_group] =&gt; 1            [id_shop] =&gt; 1            [id_cart] =&gt; 1189            [id_currency] =&gt; 1            [id_lang] =&gt; 1            [id_customer] =&gt; 8673            [id_carrier] =&gt; 43            [current_state] =&gt; 10            [secure_key] =&gt; a69d00482b1df2d13bd9a424c3a71f08            [payment] =&gt; Platba bankovním p?evodem            [module] =&gt; ps_wirepayment            [conversion_rate] =&gt; 1.000000            [recyclable] =&gt; 0            [gift] =&gt; 0            [gift_message] =&gt;             [mobile_theme] =&gt; 0            [shipping_number] =&gt;             [total_discounts] =&gt; 0.000000            [total_discounts_tax_incl] =&gt; 0.000000            [total_discounts_tax_excl] =&gt; 0.000000            [total_paid] =&gt; 312.000000            [total_paid_tax_incl] =&gt; 312.000000            [total_paid_tax_excl] =&gt; 274.000000            [total_paid_real] =&gt; 0.000000            [total_products] =&gt; 179.000000            [total_products_wt] =&gt; 217.000000            [total_shipping] =&gt; 95.000000            [total_shipping_tax_incl] =&gt; 95.000000
