我根据提供给this question 的答案按照指示行事 但对我来说无法正常工作。所以我重新提出了这个问题。 我的控制器是
public function save() {
$med_group = MedicineGroup::create(Request::all());
if ($med_group) {
$this->setServerMessage('MedicineGroup created successfully');
return Redirect::to('admin/user/create')->with('flashmessage',$this->getServerMessage());
}
}
我在Controller.php中创建了setServerMessage（）和getServerMessage（）
public function setServerMessage($messagearray) {
if (is_array($messagearray)) {
$type = $messagearray['type'];
$html = "<div style='height:auto;padding:7px 0px 6px 20px;margin:0px' class = 'pull-left text-left col-md-8 alert alert-{$type}'>{$messagearray[0]}</div>";
} else {
$html = "<div style='height:33px;padding:7px 0px 6px 20px;margin:0px' class = 'pull-left text-left col-md-8 alert alert-info'>{$messagearray}</div>";
}
$temp = '';
if (\Session::get('SERVER_MESSAGE')) {
$temp = \Session::get('SERVER_MESSAGE');
}
\Session::put('SERVER_MESSAGE', $temp . $html);
}
public function getServerMessage() {
if (\Session::get('SERVER_MESSAGE')) {
$temp = \Session::get('SERVER_MESSAGE');
\Session::forget('SERVER_MESSAGE');
return $temp;
} else
return "";
}
我的观点设置如下
<div class="box-footer text-right">
@include('flash')
<input type="submit" class="btn btn-success" value='Save'>
<input type="reset" class="btn btn-primary" value='Reset' />
<a href="#" class="btn btn-danger">Cancel</a>
</div>
在我的flash.blade.php中写了
@if(isset($flashmessage))
{!! $flashmessage !!}
@endif
我错过了什么？我跟着this site too，但我不能在我看来发短信。

现在获取视图刀片文件中的消息
<强>刀片
session()->flash('msg', 'Successfully done the operation.');
return Redirect::to('admin/user/create');
答案 1 :(得分：0)
试试这个，我正在替换你的整个代码，你可以根据需要改变它：
public function save()
{
$med_group = MedicineGroup::create(Request::all());
if ($med_group) {
//$this->setServerMessage('MedicineGroup created successfully');
// flash method to be used when just printing the message
// on the screen. Link below
\Session::flash('key', 'Your message here...');
return Redirect::to('admin/user/create');
}
}
在您的视图文件中：
@if(Session::has('key))
{{ Session::get('key') }}
@endif

every other thing seems to be fine except for your layout
laravel would escape the variable you are passing into the session while using this
@if(isset($flashmessage))
**{!! $flashmessage !!}**
@endif
you should do this instead
@if(isset($flashmessage))
**{{ $flashmessage }}**
@endif
