Confirmation alert box with Laravel contact form
提问by J86
I am new to Laravel but have managed to get a contact form working and showing validation errors when there are some.
我是 Laravel 的新手，但已设法使联系表单正常工作并在出现验证错误时显示验证错误。
However I do have one problem and have no idea how to handle it in Laravel. When a message is sent (validation rules pass) I would like to display an alert box (Bootstrap style) saying 'Thanks, message has been sent'.
但是我确实有一个问题，不知道如何在 Laravel 中处理它。当发送消息（验证规则通过）时，我想显示一个警告框（引导程序样式），上面写着“谢谢，消息已发送”。
CODE
代码
public function postContact()
{
$formData = Input::all();
// input validator with its rules
$validator = Validator::make(
array(
'name' => $formData['name'],
'email' => $formData['email'],
'subject' => $formData['subject'],
'message' => $formData['message']
),
array(
'name' => 'required|min:3',
'email' => 'required|email',
'subject' => 'required|min:6',
'message' => 'required|min:5'
)
);
if ($validator -> passes()) {
// data is valid
Mail::send('emails.message', $formData, function($message) use ($formData) {
$message -> from($formData['email'], $formData['name']);
$message -> to('[email protected]', 'John Doe') -> subject($formData['subject']);
});
return View::make('contact');
} else {
// data is invalid
return Redirect::to('/contact') -> withErrors($validator);
}
}
How can I achieve this in Laravel 4?
我怎样才能在 Laravel 4 中实现这一点？

You could use the withmethod of the Redirectclass:
您可以使用该类的with方法Redirect：
if ($validator -> passes()) {
// data is valid
Mail::send('emails.message', $formData, function($message) use ($formData) {
$message -> from($formData['email'], $formData['name']);
$message -> to('[email protected]', 'John Doe') -> subject($formData['subject']);
});
//Redirect to contact page
return Redirect::to('/contact')->with('success', true)->with('message','That was great!');
} else {
// data is invalid
return Redirect::to('/contact') -> withErrors($validator);
}
You will be redirected to the contact page with the session variables successand messageset.
您将被重定向到带有会话变量success和message设置的联系页面。
Use them for an alert in your view, e.g. in a Bootstrap Alert:
将它们用于您视图中的警报，例如在 Bootstrap 警报中：
with Blade
带刀片
@if(Session::has('success'))
<div class="alert alert-success">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Success!</strong> {{ Session::get('message', '') }}
</div>
@endif
without Blade
不带刀片
<?php if(Session::has('success')): ?>
<div class="alert alert-success">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<strong>Success!</strong> <?php echo Session::get('message', ''); ?>
</div>
<?php endif; ?>
If you are using them like this you can even provide success alerts, info alerts, or any alert you want to.
如果您像这样使用它们，您甚至可以提供成功警报、信息警报或任何您想要的警报。

I assume you are using Bootstrap so this answer will show the message in pop up window (I test it on Laravel 5)
我假设您正在使用 Bootstrap，因此此答案将在弹出窗口中显示消息（我在 Laravel 5 上对其进行了测试）
return View::make('contact')->with('message', "Thanks, message has been sent");
Make sure this code will be added in footer
确保将在页脚中添加此代码
<!-- Show Pop up Window if there is message called back -->
<?php
if(session('message'))
{
echo '<script>
document.getElementById("popup_message").click();
</script>';
}
?>
Add this function in helper.phpso you can use it anywhere in your code
在helper.php 中添加此函数，以便您可以在代码中的任何位置使用它
function message_pop_up_window($message)
{
$display = '
<a class="popup_message" id="popup_message" data-toggle="modal" data-target="#message" href="#"></a>
<div class="modal fade" id="message" role="dialog">
<div class="modal-dialog modal-md">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Messsage </h4>
</div>
<div class="modal-body">
<p>'.$message.'</p>
</div>
</div>
</div>
</div>
</div>';
return $display;
}
Then call the function in you page
然后调用页面中的函数
{!! message_pop_up_window($message) !!}

When your data is INVALID you use the withErrors()method to pass some data (erros) to your route.
You can use the same process with any kind of data.
当您的数据无效时，您可以使用该withErrors()方法将一些数据（错误）传递给您的路线。您可以对任何类型的数据使用相同的过程。
For example:
例如：
return View::make('contact')->withMessage("Thanks, message has been sent");
This method withMessage()will create a new variable messageand store it in the Session for one request cycle.
此方法withMessage()将创建一个新变量message并将其存储在 Session 中，以供一个请求周期使用。
So, in your view you can access it like this:
因此，在您看来，您可以像这样访问它：
@if(Session::has('message'))
<div class="alert-box success">
{{ Session::get('message') }}
</div>
@endif
