问题:

Wordpress产品数据刮刀/API

章增
2023-03-14

我想自动从其他网站获取产品数据,或者通过抓取它,或者通过使用cURL访问API。由于我们的网站使用Wordpress,我正在尝试制作一个插件。我现在尝试在插件的设置页面上获取字段,以填写网站名称、cURL的链接格式以及应该导入的产品ID。插件的设置页面上会有一个按钮,当再次单击时,该按钮会添加相同的字段。我试图使用一个对象类,因为我想使用多个网站。我在我们的网站上收到HTTP错误500,所以我认为在我的代码中“/**开始插件设置页面”部分之后我做错了什么。如果有人检查我的代码并给我一个正确的方向,那就太好了:)。我对PHP也很陌生,所以如果有关于如何使代码更具可读性或如何以更好的方式获取产品数据的提示,那就太好了!

你好,玛蒂恩
