Yii Error Handler with Whoops
Integrates the Whoops library into Yii 1.1 and enables further error processing.
CErrorHandler behaviour is to use internal error views to display development problems,
such as the
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 :)
- Using Composer (it will automatically install Whoops main libraries as well):
composer require igorsantos07/yii-whoops:1 composer install
- Or downloading and unpacking it in your
If you're using Composer, I strongly recomend you to create a
vendoralias if you haven't yet. Add this to the beginning of your
config/main.phpwith the error handler class. Example:
'errorHandler' => ['class' => 'vendor.igorsantos07.yii-whoops.WhoopsErrorHandler']
If you're using some custom LogRoute that binds to the application's end, you can disable it using the component's
disabledLogRoutesproperty. 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
'errorHandler' => [ 'class' => 'vendor.igorsantos07.yii-whoops.WhoopsErrorHandler', 'disabledLogRoutes' => 'MyCustomRouteClass' ]
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
errorActionproperty into the
errorHandlerabove, but with the following differences:
Yii::app()->errorHandler->errornow can be a
CEventin case of PHP errors or a normal
Exceptionin 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.
WhoopsErrorHandleryou'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.
