With WebFromParser you can parse a HTML form that you get with a POST request into a Go struct.

Features:

Usage

Given you have the following HTML form:

<form>
    <input name="FieldA">
    <input name="FieldB" type="number">
    <input name="FieldC" type="checkbox">
</form>

You can parse it into a struct with:

type MyForm struct {
    FieldA string
    FieldB int
    FieldC bool
}

func handleFormPost(w http.ResponseWriter, r *http.Request) {
    form, err := webformparser.ParseForm(MyForm{}, r)
    if err != nil {
        // handle error
    }

    fmt.Printf("Value for FieldA: %s\n", form.FieldA)
}

For a complete example take a look at the Demo.
