| * Add ReCaptcha control to your forms.␊ |
| *␊ |
| * You need first to get a ReCaptcha account, create a domain and get␊ |
| * the API keys for your domain. Check http://recaptcha.net/ for more␊ |
| * information.␊ |
| *␊ |
| * The recaptcha field needs to know the IP address of the user␊ |
| * submitting the form and if the request is made over SSL or␊ |
| * not. This means that you need to provide the $request object in the␊ |
| * extra parameters of your form.␊ |
| *␊ |
| * To add the ReCaptcha field to your form, simply add the following␊ |
| * to your form object (note the use of $extra['request']):␊ |
| *␊ |
| * <pre>␊ |
| * $ssl = (!empty($extra['request']->SERVER['HTTPS']) ␊ |
| * and $extra['request']->SERVER['HTTPS'] != 'off');␊ |
| *␊ |
| * $this->fields['recaptcha'] = new Pluf_Form_Field_ReCaptcha(␊ |
| * array('required' => true,␊ |
| * 'label' => __('Please solve this challenge'),␊ |
| * 'privkey' => 'PRIVATE_RECAPTCHA_KEY_HERE',␊ |
| * 'remoteip' => $extra['request']->remote_addr,␊ |
| * 'widget_attrs' => array(␊ |
| * 'pubkey' => 'PUBLIC_RECAPTCHA_KEY_HERE',␊ |
| * ),␊ |
| * ));␊ |
| * </pre>␊ |
| *␊ |
| * Then in your template, you simply need to add the ReCaptcha field:␊ |
| * ␊ |
| * <pre>␊ |
| * {if $form.f.recaptcha.errors}{$form.f.recaptcha.fieldErrors}{/if}␊ |
| * {$form.f.recaptcha|safe}␊ |
| * </pre>␊ |
