README

Forms

GoDoc

Forms is a lightweight, but incredibly useful go library for parsing form data from an http.Request. It supports multipart forms, url-encoded forms, json data, and url query parameters. It also provides helper methods for converting data into other types and a Validator object which can be used to validate the data. Forms is framework-agnostic and works directly with the http package.

Version 0.4.0

Development Status

Forms is being actively developed and is well-tested. However, since it is still a young library, it is not recommended for use in mission-critical production applications at this time. It is probably fine to use for low-traffic hobby sites, and in fact we encourage its use in those settings to help polish the API and find missing features and hidden bugs. Pull requests and issue reports are much appreciated :)

Forms follows semantic versioning but offers no guarantees of backwards compatibility until version 1.0. Keep in mind that breaking changes might occur. We will do our best to make the community aware of any non-trivial breaking changes beforehand. We recommend using a dependency vendoring tool such as godep to ensure that breaking changes will not break your application.

Installation

Install like you would any other package:

go get github.com/albrow/forms

Then include the package in your import statements:

import "github.com/albrow/forms"

Example Usage

Meant to be used inside the body of an http.HandlerFunc or any function that has access to an http.Request.

func CreateUserHandler(res http.ResponseWriter, req *http.Request) {
    // Parse request data.
    userData, err := forms.Parse(req)
    if err != nil {
        // Handle err
        // ...
    }

    // Validate
    val := userData.Validator()
    val.Require("username")
    val.LengthRange("username", 4, 16)
    val.Require("email")
    val.MatchEmail("email")
    val.Require("password")
    val.MinLength("password", 8)
    val.Require("confirmPassword")
    val.Equal("password", "confirmPassword")
    val.RequireFile("profileImage")
    val.AcceptFileExts("profileImage", "jpg", "png", "gif")
    if val.HasErrors() {
        // Write the errors to the response
        // Maybe this means formatting the errors as json
        // or re-rendering the form with an error message
        // ...
    }

    // Use data to create a user object
    user := &models.User {
        Username: userData.Get("username"),
        Email: userData.Get("email"),
        HashedPassword: hash(userData.Get("password")),
    }

    // Continue by saving the user to the database and writing
    // to the response
    // ...


    // Get the contents of the profileImage file
    imageBytes, err := userData.GetFileBytes("profileImage")
    if err != nil {
      // Handle err
    }
    // Now you can either copy the file over to your server using io.Copy,
    // upload the file to something like amazon S3, or do whatever you want
    // with it.
}
