/**
|
|
* Error Handler provides basic error and exception handling for your application. It captures and
|
|
* handles all unhandled exceptions and errors. Displays helpful framework errors when debug > 1.
|
|
*
|
|
* ### Uncaught exceptions
|
|
*
|
|
* When debug < 1 a CakeException will render 404 or 500 errors. If an uncaught exception is thrown
|
|
* and it is a type that ErrorHandler does not know about it will be treated as a 500 error.
|
|
*
|
|
* ### Implementing application specific exception handling
|
|
*
|
|
* You can implement application specific exception handling in one of a few ways. Each approach
|
|
* gives you different amounts of control over the exception handling process.
|
|
*
|
|
* - Set Configure::write('Exception.handler', 'YourClass::yourMethod');
|
|
* - Create AppController::appError();
|
|
* - Set Configure::write('Exception.renderer', 'YourClass');
|
|
*
|
|
* #### Create your own Exception handler with `Exception.handler`
|
|
*
|
|
* This gives you full control over the exception handling process. The class you choose should be
|
|
* loaded in your app/Config/bootstrap.php, so its available to handle any exceptions. You can
|
|
* define the handler as any callback type. Using Exception.handler overrides all other exception
|
|
* handling settings and logic.
|
|
*
|
|
* #### Using `AppController::appError();`
|
|
*
|
|
* This controller method is called instead of the default exception rendering. It receives the
|
|
* thrown exception as its only argument. You should implement your error handling in that method.
|
|
* Using AppController::appError(), will supersede any configuration for Exception.renderer.
|
|
*
|
|
* #### Using a custom renderer with `Exception.renderer`
|
|
*
|
|
* If you don't want to take control of the exception handling, but want to change how exceptions are
|
|
* rendered you can use `Exception.renderer` to choose a class to render exception pages. By default
|
|
* `ExceptionRenderer` is used. Your custom exception renderer class should be placed in app/Lib/Error.
|
|
*
|
|
* Your custom renderer should expect an exception in its constructor, and implement a render method.
|
|
* Failing to do so will cause additional errors.
|
|
*
|
|
* #### Logging exceptions
|
|
*
|
|
* Using the built-in exception handling, you can log all the exceptions
|
|
* that are dealt with by ErrorHandler by setting `Exception.log` to true in your core.php.
|
|
* Enabling this will log every exception to CakeLog and the configured loggers.
|
|
*
|
|
* ### PHP errors
|
|
*
|
|
* Error handler also provides the built in features for handling php errors (trigger_error).
|
|
* While in debug mode, errors will be output to the screen using debugger. While in production mode,
|
|
* errors will be logged to CakeLog. You can control which errors are logged by setting
|
|
* `Error.level` in your core.php.
|
|
*
|
|
* #### Logging errors
|
|
*
|
|
* When ErrorHandler is used for handling errors, you can enable error logging by setting `Error.log` to true.
|
|
* This will log all errors to the configured log handlers.
|
|
*
|
|
* #### Controlling what errors are logged/displayed
|
|
*
|
|
* You can control which errors are logged / displayed by ErrorHandler by setting `Error.level`. Setting this
|
|
* to one or a combination of a few of the E_* constants will only enable the specified errors.
|
|
*
|
|
* e.g. `Configure::write('Error.level', E_ALL & ~E_NOTICE);`
|
|
*
|
|
* Would enable handling for all non Notice errors.
|
|
*
|
|
* @package Cake.Error
|
|
* @see ExceptionRenderer for more information on how to customize exception rendering.
