How to Parse HTML Form Input Using Goji in Golang?

Parse Input from HTML Form with Golang

Within the Goji framework, parsing form input allows for seamless retrieval of data submitted via HTML forms. This enables developers to handle user input and perform operations in response.

To parse form input in Goji, follow these steps:

1. Create a Form Handler Function:

import (
    "fmt"
    "net/http"

    "github.com/zenazn/goji"
    "github.com/zenazn/goji/web"
)

func hello(c web.C, w http.ResponseWriter, r *http.Request) {

    // Call r.ParseForm() before reading form values
    if err := r.ParseForm(); err != nil {
        // Handle error handling here
    }

    name := r.PostFormValue("name")
    fmt.Fprintf(w, "Hello, %s!", name)
}

2. Register the Form Handler with Goji:

func main() {
    goji.Handle("/hello", hello)
    goji.Serve()
}

3. Submit an HTML Form with the Necessary Input:

<form action="/hello" method="get">
    <input type="text" name="name">
    <input type="submit" value="Submit">
</form>

When the form is submitted, the Goji framework will parse the input (in this case, the value of the "name" field) and pass it to your form handler function, which can then process the input accordingly.
