I am trying to check is the user logged inside my view file, but I keep getting this error:
Call to undefined method Yii::app()
I tried adding $ before app but the error is still there (this time it is Undefined variable: app). Is it possible to this is view?
This is the code I use the check if the user is logged:
<?php
if(Yii::app()->isGuest)
echo 'User is not logged!';
?>
In Yii2 the correct syntax is
Yii::$app->user->getIsGuest();
or
Yii::$app->user->isGuest;
Look at the documentation for more details: http://www.yiiframework.com/doc-2.0/yii-web-user.html
Hope it helps.
In yii2 you have to define the app() with $ sign as $app().
<?php
if(Yii::$app->user->isGuest){
echo 'User is not logged!';
}
?>

Hi,
I've been trying a lot of options to manage an exception and show an error at admin panel but nothing seems to work.
I'm at the postProcess method of a custom module. After the user sends a csv file through a form and the data is checked (everything works fine here), if an exception occurs I need to show a message, stop and redirect to the same page.
I've tried this:
this->get('session')->getFlashBag()->add('error',$msg);
Tools::redirectAdmin('index.php?controller='.$controller.'&token='.$token);
this:
header("HTTP/1.0 400 Bad Request");
die(json_encode(array( 'error' => array($this->l(' Error') ))));
(that one works but shows a blank page with the message, not the message inside the admin panel)
also this:
$this->context->smarty->assign(array(
'token' => Tools::getAdminTokenLite('AdminModules'),
'errors' => $this->errors
));
$this->setTemplate('ExcelProcess.tpl');
and {$errors|var_dump} at the tpl displays null...
... and many other options.
I can't find anything either about backoffice custom notifications at the PS docs, only about front custom notifications.
Any clue?
Thanks a lot!

Adding an error in postProcess() can be achieved by setting
$this->errors[] = $this->l('My error');
or
$this->context->controller->errors[] = $this->l('My error');
during your form submission checks.
Form will be rendered with your error messages into a red box.
If you want to show an alert without reloading the page instead, you'll have to perform an AJAX call to your AdminController, get back a JSON response and render your error message as a result of the execution of the call.
See offical docs
I'm trying to have separate files for all my error messages. (404, 403, 500 etc) so i can have custom designs for them. If possible i don't want the header and footer to be included in my error pages too. Right now i have this, in my SiteController.php and put error404.php into my views/site/ folder
public function actionError()
{
$error = Yii::app()->errorHandler->error;
switch($error['code'])
{
case 404:
$this->render('error404', array('error' => $error));
break;
.......
.......
}
}
i was wondering if there is a better way? or if Yii has way to handle this that i'm missing.
i read this page http://www.yiiframework.com/doc/guide/1.1/en/topics.error
and it says something about putting files into /protected/views/system but i don't quite understand Yii's documentation.
As you read Yii will look for files in /protected/views/system (after looking in themes if you have any)
You do not need to write any fresh actions all you have to do is create a folder system in the views directory and create files named errorXXX.php XXX being the error code.
The default page looks like this you modify this as you wish and save it in /protected/views/system
<body>
<h1>Error <?php echo $data['code']; ?></h1>
<h2><?php echo nl2br(CHtml::encode($data['message'])); ?></h2>
<p>
The above error occurred when the Web server was processing your request.
</p>
<p>
If you think this is a server error, please contact <?php echo $data['admin']; ?>.
</p>
<p>
Thank you.
</p>
<div class="version">
<?php echo date('Y-m-d H:i:s',$data['time']) .' '. $data['version']; ?>
</div>
</body>
You will have access to following attributes in your $data array
code: the HTTP status code (e.g. 403, 500);
type: the error type (e.g. CHttpException, PHP Error);
message: the error message;
file: the name of the PHP script file where the error occurs;
line: the line number of the code where the error occurs;
trace: the call stack of the error;
source: the context source code where the error occurs.
The alternative technique is how you created an action in SiteController,however to activate this you need to change your main config file and route errors to this action:
return array(
......
'components'=>array(
'errorHandler'=>array(
'errorAction'=>'site/error',
),
),
);
If you wish to only skin your errors then this is not necessary, if you want to do more complex stuff like on error log to a DB, send a email to the admin etc then it is good to have your own action with additional logic.
I am using Yii form Like this.
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'customerContactForm',
'action' => array( '/customer/ContactFormEmail' ),
'enableClientValidation'=>true,
'clientOptions'=>array(
'validateOnSubmit'=>true,
));>?
On console I Got this error,
Uncaught TypeError: Object [object Object] has no method 'yiiactiveform'
But after searching about this problem,I add this line of code to my view file.
<script type="text/javascript" src="../assets/795f6a2f/jquery.yiiactiveform.js"> </script>
It start working,But I do not want to get js from assets folder.So I try this
Yii::app()->clientScript->registerCoreScript('yiiactiveform');
Yii::app()->clientScript->registerCoreScript('jquery');
But I am getting the same problem.
You must connect Jquery Before than yiiactiveform. As is often the case that the Jquery file is connected to the page twice. You need to remove the explicit connection Jquery in view code. The framework will decide when it needs.
If you do need one to do it manually - insert only the following code in the page header:
Yii::app()->clientScript->registerCoreScript ('jquery');
I am able to render my specified error pages in my modules, but I can't get error layouts outside of my modules.
It's quite strange, in my main config I have:
'errorHandler'=>array(
'errorAction'=> '//site/error',
),
I tried to see if it is pointed to the right file by changing it to //site/contact, and see if it renders the contact page if error. And it does show.
So the path is correct, then how come it's not showing the error page? It shows the default white page with exception error. The exception page is what im expecting, but how it's formatted is not.
public function actionError()
{
$this->layout = '/layouts/main';
if($error=Yii::app()->errorHandler->error)
{
if(Yii::app()->request->isAjaxRequest)
echo $error['message'];
else
$this->render('error', array('error'=>$error));
}
}
Your user role doesn't have rights to access actionError() in controller.
In your site controller, You can see a function called public function accessRules().
Check error is added for some user role, or it's for admin only.
If error not found, then add it for user roles.
Example:
public function accessRules()
{
return array(
array('allow',
'actions' => array('index', 'view', 'error'),
'users' => array('#')
),
..
..
..
}
You need to create a errorXXX in views/system. The XXX stand for the error code, in this case most likely a 403. For more information see this page on the Yii site.
My urlManager rules: (basically the one comes default)
'<controller:\w+>/<id:\d+>'=>'<controller>/view',
'<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
'<controller:\w+>/<action:\w+>'=>'<controller>/<action>',`
My controller:
class SiteController extends Controller {
public function actionSubscribe() {
echo 'gdg';
die();
}
}
My view:
<form method="POST" action="<?php echo $this->createUrl('site/subscribe'); ?>" style="display: inline;">
<input style="margin: 0 18px 0 6px;" type="text" value="e-mail"/>
</form>
When I access it using the url http://localhost/site/subscribe directly it works, but when I type something in the text field and push my enter button to post the form it says The system is unable to find the requested action "error".
I'm very certain that it has something to do with my form. I have so far no problem using active form but for this form I don't have a model and I don't want to use form builder. Any help?
"When I access it using the url http://*/site/subscribe directly it works"
=> You execute subscribe action with GET method.
"but when I type something in the text field and push my enter button to post the form it says The system is unable to find the requested action "error"."
=> You execute subscribe action with POST method.
=> There are some errors and I think Yii try to handle error with your default configure:
return array(
......
'components'=>array(
'errorHandler'=>array(
'errorAction'=>'site/error',
),
),
);
However, Yii can't find error action with your SiteController so it throws The system is unable to find the requested action "error". You can add error action to see information about errors like:
public function actionError()
{
if($error=Yii::app()->errorHandler->error){
$this->render('error', $error);
}
}
More info: The above error variable is an array with the following fields:
code: the HTTP status code (e.g. 403, 500);
type: the error type (e.g. CHttpException, PHP Error);
message: the error message;
file: the name of the PHP script file where the error occurs;
line: the line number of the code where the error occurs;
trace: the call stack of the error;
source: the context source code where the error occurs.
