then send poems to a Wi-Fi Mysql database.
I recognize all the words. The order that they are arranged in makes no sense. What kind of column definition are you using for the poem column? The database doesn't live on a router, so the WiFi term is confusing.
The WiFi shield lets you connect to an existing local area network that the router is connected to. Beyond that, you need to write code on the Arduino to talk to some server on which the MySQL database is running. It's unlikely that you are storing poems in a database.
I suggest that you try again.
