500 Errors
You may use the Slim application’s error()
method to specify a custom error handler to be invoked when an error orexception occurs. Custom error handlers are only invoked if application debugging is disabled.
A custom error handler should render a user-friendly message that mitigates user confusion. Similar to the Slimapplication’s notFound()
method, the error()
method acts as both a getter and a setter.
Set custom error handler
You may set a custom error handler by passing a callable into the Slim application’s error()
method as its firstand only argument.
<?php
$app = new \Slim\Slim();
$app->error(function (\Exception $e) use ($app) {
$app->render('error.php');
});
In this example, the custom error handler accepts the caught Exception as its argument. This allows you to respondappropriately to different exceptions.
Invoke custom error handler
Usually, the Slim application will automatically invoke the error handler when an exception or error occurs.However, you may also manually invoke the error handler with the Slim application’s error()
method(without an argument).
