Form Validation

you can create a form, to valid the user’s input, and get the clean value.

import "github.com/QLeelulu/goku/form"

func CreateCommentForm() *goku.Form {
    name := NewCharField("name", "Name", true).Range(3, 10).Field()
    nickName := NewCharField("nick_name", "Nick Name", false).Min(3).Max(20).Field()
    age := NewIntegerField("age", "Age", true).Range(18, 50).Field()
    content := NewTextField("content", "Content", true).Min(10).Field()

    form := NewForm(name, nickName, age, content)
    return form
}

and then you can use this form like this:

f := CreateCommentForm()
f.FillByRequest(ctx.Request)

if f.Valid() {
    // after valid, we can get the clean values
    m := f.CleanValues()
    // and now you can save m to database
} else {
    // if not valid
    // we can get the valid errors
    errs := f.Errors()
}
