Catching error exceptions in Laravel 4
提问by majidarif
From the documentation it says we can catch all 404 like so:
从文档中它说我们可以像这样捕获所有 404：
App::missing(function($exception)
{
return Response::view('errors.missing', array(), 404);
});
And we can also do things like:
我们还可以执行以下操作：
App::abort(404);
App::abort(403);
All 404 gets handled by the App::missing
所有 404 都由 App::missing
All other errors gets handled by:
所有其他错误由以下方式处理：
App::error(function( HttpException $e)
{
//handle the error
});
But the question is How do i handle each of the error like if its a 403 I will display this if its a 400 I will display another error
但问题是 How do i handle each of the error like if its a 403 I will display this if its a 400 I will display another error

Short answer: if your custom App::error function does not return a value, Laravel will handle it. Check the docs
简短回答：如果您的自定义 App::error 函数没有返回值，Laravel 会处理它。检查文档
Code sample for custom error views and/or logic:
自定义错误视图和/或逻辑的代码示例：
App::error(function(Exception $exception, $code){
// Careful here, any codes which are not specified
// will be treated as 500
if ( ! in_array($code,array(401,403,404,500))){
return;
}
// assumes you have app/views/errors/401.blade.php, etc
$view = "errors/$code";
// add data that you want to pass to the view
$data = array('code'=>$code);
// switch statements provided in case you need to add
// additional logic for specific error code.
switch ($code) {
case 401:
return Response::view($view, $data, $code);
case 403:
return Response::view($view, $data, $code);
case 404:
return Response::view($view, $data, $code);
case 500:
return Response::view($view, $data, $code);
}
});
The above snippet could be inserted in app/start/global.phpafter the default Log::error handler, or better yet in the boot method of a custom service provider.
上面的代码片段可以插入app/start/global.php中默认 Log::error 处理程序之后，或者更好地插入自定义服务提供者的 boot 方法中。
EDIT: Updated so the handler only processes codes you specify.
编辑：已更新，因此处理程序仅处理您指定的代码。
