Mealie Widget [PHP]

[danz0l99]

This is a simple widget to grab statistics from your running mealie server.

Please make sure to fill in the server and token sections of the widgets parameters with your own values.

To generate a token, please visit your mealie admin panel.

This widget utilizes the mealie endpoint: /api/admin/about/statistics.

Note that this is my first time working with API calling, so the code may require refinement and better presentation. Hope it helps someone and thanks [DickenSerm] for providing me with the motivation to go the PHP route and create this, by providing your excellent paperless widget example #143
