Wordpress Yelp评论Ticker插件

Question

我制作了这个插件来展示来自我的业务的yelp的评论，这是我的第一次尝试，它很有效，但我想和大家分享它。当我在代码上添加我的设置时，它的工作方式应该是这样的。但当我制作管理界面，以便人们可以使用他们自己的API密钥，并改变外观到他们最合适的，它不会“保存”设置，也不会工作。我希望有人能给我一些启发和帮助，这样我就可以分享代码/插件了。(顺便说一下，这是我第一次尝试编码)

我知道我还有很多代码清理工作要做

Answer 1

事实上，在wordpress调用$instance之前，我就在使用一个非常古老的“插件模板”。因此，人们习惯于创建自己的实例，这就是我所做的。我已经清理了我的代码，并让它正常工作。我遇到的唯一问题是，一旦jQuery接管，我的css就不能在插件中工作。但这是一个不同的问题。这是我的解决办法
