You can use c.FormValue for simple forms, and keep in mind that the return value is always a string. So if you want to send integers as well you will have to manually convert them to integers in handlers. for more complex forms like sending files you can use c.MultipartForm.

func main() {
    // create new fiber instance  and use across whole app
    app := fiber.New()

    // middleware to allow all clients to communicate using http and allow cors
    app.Use(cors.New())

    // homepage
    app.Get("/", func(c *fiber.Ctx) error {
        // rendering the "index" template with content passing
        return c.Render("index", fiber.Map{})
    })

    // app.Post because method="POST"
    // "/" because action="/"
    app.Post("/", handleFormUpload)

    // start dev server on port 4000
    log.Fatal(app.Listen(":4000"))
}

func handleFormUpload(c *fiber.Ctx) error {
    email := c.FormValue("email")
    content := c.FormValue("content")

    fmt.Println(email, content)
    return c.JSON(fiber.Map{"status": 201, "message": "Created!"})
}
