Editing Recaptcha (section)

== Adding reCAPTCHA to User Registration ==
First we have to add the reCAPTCHA field to the user config.
I added the following code to the end of my recaptcha.pl file, but you could also add the field definition directly to the 'user_fields.pl' file.
<source lang="perl">
#Add field to user dataset
$c->add_dataset_field( "user", {
        name => "captcha",
        type => "recaptcha",
});
</source>
Now reload the configuration and update the database (through the web interface Admin->Config. Tools -> Reload Config / Update Database) - or via the command line.

Next, we have to add the field to the user registration workflow. If you haven't edited the registration workflow, look at ~/lib/workflows/user/register.xml. Add the following component after the existing Field::Multi component.
<source lang="xml">
<component surround="None"><field ref="captcha" /></component>
</source>
''If you are running multiple archives and some need reCAPTCHA and others don't, copy the register.xml file into ~/archives/ARCHIVEID/workflows/user/ and edit it there.''

Reload the configuration again, and then visit your 'Create Account' page - you should have a nice shiny reCAPTCHA added to the registration!
