在php的PrestaShop中按属性过滤产品

我不仅仅是php新手，我理解部分代码，但大多数不理解

我正在修改一个模块，该模块根据所选类别将PrestaShop产品导出为PDF

现在，我希望“获取”功能能够获取所有活动的产品，而不是那些启用为“仅在线”的产品

调用产品的代码部分如下所示：

    public function getContent()
{
    $context = Context::getContext();
    $langmod = $context->langmod;
    $products = '';
    $i = 0;
    foreach (Tools::getValue('categoryBox') as $osque) {
        $productget = Product::getProducts(Context::getContext()->language->id, 0, 0, 'id_product', 'ASC', $osque, $active = true);
        $products[$i]['products'] = $productget;
        $id_lang = Context::getContext()->language->id;
        $sql = '
        SELECT `name`
        FROM `'._DB_PREFIX_.'category_lang`
        WHERE `id_category` = '.(int)$osque.'
        AND `id_lang` = '.(int)$id_lang;
        $name = Db::getInstance()->getValue($sql);
        $products[$i]['categorie'] = $name;
        $i++;
    }

检查这一点的布尔变量是：

online_only = true
online_only = false

所以我试着修改这行代码：

$productget = Product::getProducts(Context::getContext()->language->id, 0, 0, 'id_product', 'ASC', $osque, $active = true, $online_only = false);

但是我得到了一张空白页

有什么帮助吗

感谢您的时间：）

尝试使用此覆盖（在override/classes/Product.php中）：

为了避免缓存的麻烦，请删除站点根目录下缓存文件夹中的文件class_index.php

关于

你好ethercreation，你好Diego Reyes，ethercreation，我愿意为在模块中进行此类修改付费。我们是否可以私下联系？是：=）请通过MPThanks联系我，以获取您的回复，以太创意。我已经从PrestaShop论坛雇佣了一名开发人员，谢谢：）我已经解决了这个问题：D
