Integrates the Whoops library into Yii 1.1 and enables further error processing.

Current CErrorHandler behaviour is to use internal error views to display development problems, such as the error and exception views. If you're not in debug mode, it will simply call the vanilla error action and display less stuff in the screen so your users don't get ugly errors.

This new implementation allows you to - if needed - include a last, global error handler before displaying error messages. The errorAction is called and, if it can't handle the issue, we take the stage and decide what to do with the error - if you're debugging the application we will give you a really, really nice error page that will help you finding what's wrong :)


  1. Install it:

    composer require igorsantos07/yii-whoops:1
    composer install
    • Or downloading and unpacking it in your extensions folder.
  2. If you're using Composer, I strongly recomend you to create a vendor alias if you haven't yet. Add this to the beginning of your config/main.php:

    Yii::setPathOfAlias('vendor', __DIR__.'/../../vendor');
  3. Replace your errorHandler entry at config/main.php with the error handler class. Example:

    'errorHandler' => ['class' => 'vendor.igorsantos07.yii-whoops.WhoopsErrorHandler']
  4. If you're using some custom LogRoute that binds to the application's end, you can disable it using the component's disabledLogRoutes property. Just set it to an array containing all the classnames (not aliases!) of each route you want disabled whenever Whoops is launched. By default it disables the famous (Yii Debug Toolbar)ydtb; if you want to keep it enabled, override the defaultDisabledLogRoutes property.

    'errorHandler' => [
       'class'             => 'vendor.igorsantos07.yii-whoops.WhoopsErrorHandler',
       'disabledLogRoutes' => 'MyCustomRouteClass'
  5. There were some changes in the API for further error action handling. If you want to have custom error pages you can as usual include a errorAction property into the errorHandler above, but with the following differences:

    • Yii::app()->errorHandler->error now can be a CEvent in case of PHP errors or a normal Exception in case of, uh, exceptions. Have that in mind when handling errors in your action, as PHP Errors have no code and etc - however, if you're showing an error page is advised to use the standard 500 code.
    • If your action is unable to handle the error, Whoops will still get to the stage as usual. Example: all API errors in your app will show a small message and redirect the user, while other errors are real problems and should be handled by the framework's error handler. To tell WhoopsErrorHandler you've taken care of the issue, call Yii::app()->errorHandler->handled(), and then Whoops will not interfere with what the action has done; if after the action he still thinks he should do something, the Whoops error page will be called as usual.
