Wordpress 产品数据抓取工具/API [英] Wordpress prodruct data scraper/API
问题描述
我想通过抓取或通过 cURL 访问 API 来自动从其他网站获取产品数据.由于我们的网站使用 Wordpress，我正在尝试制作一个插件.我现在正在尝试获取插件设置页面上的字段，以填写网站名称、cURL 的链接格式以及应该导入的产品的 ID.插件的设置页面上会有一个按钮，单击时会再次添加相同的字段.我正在尝试使用带有对象的类，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的//**START 插件设置页面"部分之后做错了什么.如果有人审查我的代码并推动我朝着正确的方向前进，那就太好了:).我对 PHP 也很陌生，所以如果有关于如何使我的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！
亲切的问候，马丁

试试这个代码
我已将此行 $DropshipFields1->ff_dropship_data_scraper_settings(); 修改为 $DropshipFields1->ff_dropship_data_scraper_settings;
和add_menu_page代码

I want to automatically get product data from other websites either by scraping it or by accessing an API with cURL. Since our website uses Wordpress, I am trying to make a plugin. I am now trying to get fields on the plugin's settings page to fill in the name of the website, the link format for cURL and the IDs of the products that should be imported. There will be a button on the plugin's settings page which adds the same fields another time when clicked on. I am trying to use a class with objects, since I want use multiple websites. I am getting HTTP Error 500 on our website, so I think am doing something wrong after the "//**START Plugin Settings Page" part in my code. It would be great if someone reviews my code and gives me a push in the right direction :). I am also pretty new to PHP so if there are tips on how I can make my code more readable or how I can get the product data in a better way, that would be great!
Kind regards, Martijn

Try this code
I have modified this line $DropshipFields1->ff_dropship_data_scraper_settings(); to $DropshipFields1->ff_dropship_data_scraper_settings;
and add_menu_page code
