WordPress Yelp Review Ticker Plugin

1 Views

I made this plugin to show reviews from yelp from my business, it is my first attempt and it works, but I’d like to share it with everyone.
When I add my settings on the code it works the way it is supposed to. But when I made the admin interface so people can use their own API keys and change the look to their best fitting, it won’t “save” the settings and will not work.
I am hoping someone could shed some light and help me out so I can share the code/plugin.
(by the way this is my first attempt to coding)

  2. Indeed I was using a very old “plugin template” before wordpress had the $instance call.
    so people used to make their own instances, wich is what I was doing.
    I’ve cleaned up my code and got it working.
    The only problem I encountered is that my css won’t work in the plugin once jQuery takes over.
    But that is a different question.
    here is my fix
