Question

After i used multiple layouts in my app , then Cpatcha not display any image 🙁

This my code

Controller :

public function actions()
        {
                return array(
                        // captcha action renders the CAPTCHA image displayed on the contact page
                        'captcha'=>array(
                                'class'=>'CCaptchaAction',
                                'backColor'=>0xFFFFFF,
                        ),
                        // page action renders "static" pages stored under 'protected/views/site/pages'
                        // They can be accessed via: index.php?r=site/page&view=FileName
                        'page'=>array(
                                'class'=>'CViewAction',
                        ),
                );
        }

model :

public function rules()
{
        return array(
                array('email, password', 'required','message'=>'-- {attribute}  '),

                array('password', 'authenticate'),

                // verifyCode needs to be entered correctly
        array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements(),'message'=>' {attribute}  Error '),

);

}

view call widget

...
        <div>
                <?php $this->widget('CCaptcha'); ?>
                <?php echo $form->textField($model,'verifyCode'); ?>
                </div>
...

I tested it on request recorder and it sent and received requests .

Thanks in advance

Answer 1

I fixed it by add Remove Bom Function

ob_start('My_OB');
function My_OB($str, $flags)
{
    //remove UTF-8 BOM
    $str = preg_replace("/\xef\xbb\xbf/","",$str);

    return $str;
}

I guess the problem was in page encoding .
