Why?

I have several sites hosted on AWS S3 for pennies a month… and I didn’t want to pay $20 per month (per form) for processing contact forms!

20+ domains powered by 1 Heroku app = Profit!

Demo

See https://github.com/mishbahr/staticgen-fwdform

Features

• Multi site support.

• Unlimited forms

• Unlimited submissions

• Spam Protection via Akismet.

• Submit forms with AJAX.

• REST API to manage forms.

Quickstart

1. Install django-fwdform:

   pip install django-fwdform

2. Add fwdform to INSTALLED_APPS:

   INSTALLED_APPS = (
       ...
       'corsheaders',
       'fwdform',
       ...
   )

3. Sync database:

   python manage.py migrate

4. Add fwdform.urls to your project’s urls module:

   urlpatterns = patterns(
       ...
       url(r'^', include('fwdform.urls', namespace='fwdform')),
       ...
   )

Dependencies

This package requires django-cors-headers to be installed and configured correctly. When django-fwdform is installed using pip, django-cors-headers is automatically installed.

You will need to add corsheaders middleware class to MIDDLEWARE_CLASSES settings:

MIDDLEWARE_CLASSES = (
    ...
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    ...
)

Note that CorsMiddleware needs to come before Django’s CommonMiddleware.

Allow CORS requests from all domains:

CORS_ORIGIN_ALLOW_ALL = True

Sample Form

<form action="//example.com/send/<form_hash>/" method="POST">
    <input type="text" name="name" required="required"/>
    <input type="email" name="email" required="required" />
    <textarea name="message" rows="5"></textarea>
    <input type="submit" value="Send">
</form>

<input type="hidden" name="_next" value="//example.com/thanks.html" />

<input type="hidden" name="_subject" value="Contact Form" />

<input type="text" name="_gotcha" style="display:none;" />

<input type="text" name="name" placeholder="Your Name">
<input type="email" name="email" placeholder="Your Email">
<textarea name="message" rows="5"></textarea>

Rest API

Register a form, this returns a hashid for the newly created form:

$ curl --data "name=Contact%20Form&recipients=conttact@example.com" http://example.com/<site_token>/
{"hashid": "0rPGVlYZWqMRE8OebjoM1ogpmvNL23A9dxJzywQD"}

Update existing form config by passing a known hashid as a param:

$ curl --data "recipients=hello@example.com&hashid=0rPGVlYZWqMRE8OebjoM1ogpmvNL23A9dxJzywQD" http://example.com/<site_token>/

AJAX Submission

You can use fwdform via AJAX. This even works cross-origin.

If you’re using jQuery this can be done like so:

$.ajax({
    url: $form.attr("action"),
    method: "POST",
    data: $form.serialize(),
    dataType: "json",
    headers: {"X-Requested-With": "XMLHttpRequest"},
});
