Take into consideration, that you should not add your recaptcha field to required validator, as this will fail.

Also, keep in mind, that adding following line:

<?php echo CHtml::error($model, 'captcha'); ?>

below your recaptcha field works only for server-side validation. Even, if you have client-side validation enabled, it will not work this way.

Extension works like a charm, so many thanks to the creator.

If you decide to replace default verifyCode with this extension, remember to remove some then unecessary elements from your application:

• call to CCaptchaAction in actions() function in controller responsible for handling your previous bulid-in captcha,
• remove old verifyCode rule from rules() from your form model as well as public symbol $verifyCode form it,
• customize your form view, so reCAPTCHA best suits your needs,
• etc.

Remember, that you can customize look & feel of your captcha -- look into documentation for more info.

Just want to say thank you for this extension. Good work!

P.S. If someone knows how to make this work with ajax validation it would be good to share with the rest of us.

The form was successfully submitting as if the reCaptcha was not there at all. Even if it was left blank. I had to set enableAjaxValidation to FALSE and replaced the ajax validation code in my controller action, with the $model->validate() to get it work.

THANKS A LOT!!!!!!!

I suggest to update setLanguage() in EReCaptcha.php to this:

public function setLanguage($value)
{
$this->language = empty($value) ? 'en' : (($p=strpos($value,'_'))!==false) ? strtolower(substr($value,0,$p)) : strtolower($value);
if (!in_array($this->language, $this->validLanguages)) $this->language = 'en';
}

Then you can put your custom language or set it dynamically by application. And update setTheme() method too to put your custom theme.

public function setTheme($value)
{
$this->theme = $value;
if (!in_array($this->theme, $this->validThemes)) $this->theme = 'red';
}

Thank you.

thanks, very helpful.

I use this extension for a project, a website which runs over SSL.

I know that reCaptcha has support for HTTPS requests so users will not get warnings in browser (like "this page has some resources that are not sent via a secured connection") when loading a page that has reCaptcha.

This is how I got this done:

In EReCaptcha.php, I modified the line ~153 as follows:

echo recaptcha_get_html(Yii::app()->params['recaptcha_public'], null, Yii::app()->params['https']);

You do not need to change the first argument Yii::app()->params['recaptcha_public'] to use ReCaptcha via HTTPS. I did this just to avoid hardcoding it in my application. See this comment.

In configuration, protected/config/main.php, I added

params => array(
[...],
'https'=>true,
[...],
),

And, finally, I updated the reCAPTCHA/recaptchalib.php file. The latest one can be downloaded from here.

Still learning here. I hardcoded the reCaptcha keys in the code with my previous example, but it's better to follow the tips in these comments too: http://www.yiiframework.com/extension/recaptcha/#c1350 http://www.yiiframework.com/extension/recaptcha/#c1383

That is, put the keys in the config. Mind the case sensitivity as the two linked comments have different cases.

If you want to use yii-user with recaptcha, you'll need to do the following (these are all relative to yii-user module root, NOT app root):

in views/user/registration.php, replace:

<?php if (UserModule::doCaptcha('registration')): ?>
    <div class="row">
        <?php echo CHtml::activeLabelEx($form,'verifyCode'); ?>
        <div>
        <?php $this->widget('CCaptcha'); ?>
        <?php echo CHtml::activeTextField($form,'verifyCode'); ?>
        </div>
        <p class="hint"><?php echo UserModule::t("Please enter the letters as they are shown in the image above."); ?>
        <br/><?php echo UserModule::t("Letters are not case-sensitive."); ?></p>
    </div>
    <?php endif; ?>

with

<?php if (UserModule::doCaptcha('registration')): ?>
    <div class="row">
        <?php echo CHtml::activeLabel($form, 'verifyCode'); ?>
        <?php
                $this->widget('application.extensions.recaptcha.EReCaptcha',
                        array('model' => $form, 'attribute' => 'verifyCode',
                            'theme' => 'red', 'language' => 'en_US',
                            'publicKey' => 'PUBLIC KEY  HERE'))
        ?>
    </div>
    <?php endif; ?>

in models/RegistrationForm.php, replace the verifyCode rule with this:

array('verifyCode', 'application.extensions.recaptcha.EReCaptchaValidator', 'privateKey' => 'PRIVATE KEY HERE'),

and very important:

In controllers/RegistrationController.php, around line 45, find this line:

if ($model->save()) {

and change it to:

if ($model->save(false)) {

Here's the reason the last bit is important: The call to the reCaptcha server is only valid ONCE. However, this controller ends up calling it twice, once at line 34 ($model->validate()) and then again at line 45 ($model->save()) because the save() actually calls the validate() again.

Passing false as a parameter to save() will bypass the validation, which is okay because we just did it a few lines earlier.

Hope this saves someone a few hours. :)

There is an extraneous comma after {$this->tabIndex}, <---

Please remove it from code since this will cause the theme to not work in IE.

$script =<<theme}', custom_theme_widget : {$customthemewidget}, lang : '{$this->language}', tabindex : {$this->tabIndex} }; EOP;

I had a little hick-up at the beginning, but now it works great. I will use this everywhere ;)

in order to do so just rewrote two lines in both php files of this extension and replace $this->public/private with Yii::app()->params['reCaptcha']['publicKey'] and Yii::app()->params['reCaptcha']['privateKey'].

It works like a charm now.

Thanks for the extension. I'd like to use it in a little bit different way. I do not want to type keys manually in each recaptcha widget, instead of this I define keys in config:

'params'=>array('recaptcha'=>array(
           
   'publicKey'=>'YOUR PUBLIC KEY',
           
   'privateKey'=>'YOUR PRIVATE KEY',
       
   ),
)

Thank you!

Nice interface to recaptcha
