Buenas a todos/as,
Estoy tratando de implantar un Captcha en el inicio de sesión (login) de los usuarios en la extensión Yii-user, me surgen dos problemas:
[list=1]
[*] La primera vez que carga la página la imagen no aparece.
[*] La segunda vez que se envía el formulario metiendo un código de verificación erróneo, nombre de usuario y contraseña incorrecta, el usuario consigue hacer login. En cambio la primera vez lo hace bien y no se autentica.
[/list]
Os pego el código por aquí y os doy las gracias anticipadas a todos.
Vista del formulario:
<?php //if (UserModule::doCaptcha('login')): ?>
<div>
<?php $this->widget('CCaptcha'); ?>
</div>
<div>
<?php echo CHtml::activeLabelEx($model,'verifyCode'); ?>
<?php echo CHtml::activetextField($model,'verifyCode'); ?>
<p><?php echo UserModule::t("Please enter the letters as they are shown in the image above."); ?>
<br/><?php echo UserModule::t("Letters are not case-sensitive."); ?></p>
<?php echo CHtml::error($model,'verifyCode'); ?>
</div>
<?php //endif; ?>
Controlador:
public function accessRules() {
return array(
array('allow',
'actions'=>array('captcha'),
'users'=>array('*'),

$this->redirect(Yii::app()->controller->module->returnUrl);

$this->redirect(Yii::app()->user->returnUrl);

}
// display the login form
$this->render('/user/login',array('model'=>$model));
