[英]Laravel show errors in view
if my validation fails I do this: 如果我的验证失败,我这样做:
return Redirect::back()->with('validation', $validation->errors->all());
also I am using: 我也在使用:
$restful = true;
so when I am on get_edit()
- I'am getting an error that there are no $validation variable when generating my view, when in post_edit()
- its all okay because its returns a redirect with errors... 所以,当我在
get_edit()
- 我收到一个错误,在生成我的视图时没有$ validation变量,在post_edit()
- 它一切正常,因为它返回一个有错误的重定向...
this is my view: 这是我的看法:
<? foreach($validation as $e): ?>
<div><?= $e; ?></div>
<? endforeach; ?>
undefined variable $validation, right now I'am trying to put it on the Router::before undefined变量$ validation,现在我试着把它放在Router ::之前
Route::filter('before', function()
{
View::share('validation', array());
});
so the variable exists but is empty, but now arises a new problem, everytime after this filter executes it overrides those $validation
that generates my post_edit()
, also i've seen a variable $errors
in my view but is ever empty, i don't how to use it, can you help me? 所以变量存在但是是空的,但是现在出现了一个新问题,每次在这个过滤器执行之后它会覆盖那些生成我的
post_edit()
$validation
,同样我在我的视图中看到变量$errors
但是它是空的,我不要怎么用它,你能帮帮我吗?
so shortly my problem is: 所以很快我的问题是:
public function get_edit($id)
{
//generate my view with all nessesary data, but i can't generate here an error variable
// or its better to put it in one place to globally share it in the views, otherwise i am //getting an error
}
public function post_edit($id)
{
//validating $_POST data, if there is an error redirect it back to the get_edit() WITH a //variable containing errors
}
Did you read the docs? 你读过文档了吗? http://laravel.com/docs/5.0/validation#error-messages-and-views
http://laravel.com/docs/5.0/validation#error-messages-and-views
You can use return Redirect::back()->withErrors($validation);
您可以使用
return Redirect::back()->withErrors($validation);
In your views, you can always use redirect('register')->withErrors($validator) $errors
, without binding them to the view. 在您的视图中,您始终可以使用重定向('register') - > withErrors($ validator)
$errors
,而不将它们绑定到视图。
