Prestashop 1.6 创建独立的 php 文件来列出产品

Question

我正在尝试创建一个 PHP 文件，以便以 XML 格式显示我的所有产品。 PHP 文件位于 PS 安装的 ROOT 目录中。

您能告诉我如何在不向页面添加 html 和 body 标签的情况下初始化 PS 吗？ 我还想获得产品的 PublicPrice 和 PriceWithoutReduction。

当我尝试此代码时，出现致命错误。 网址：http://www.topludo.fr/xml_guide.php

谢谢您的提前。

Answer 1

要初始化 PrestaShop，请使用：

require_once __DIR__.DIRECTORY_SEPARATOR.'config'.DIRECTORY_SEPARATOR.'config.inc.php';
require_once __DIR__.DIRECTORY_SEPARATOR.'init.php';

我建议使用

SimpleXML

，而不是使用标头将内容类型设置为 xml，然后echo标记。操作 XML 变得更加容易，并且代码也更容易阅读。创建

SimpleXMLElement

并将所有产品属性添加为子项后，您可以使用

asXML

方法获取 XML 字符串，也可以通过将文件名参数传递给

asXML

将 XML 保存到文件中。
