How to add an alert on Laravel 5?
提问by Iqbal Nurkholik
I have a function where:
After I click the link named "hapus", the related data will be deleted and I want to have a popup alert to show that the data has been deleted.
*sorry for my bad english
*hapus technically means destroy
我有一个功能，其中：
单击名为 的链接后"hapus"，相关数据将被删除，我希望有一个弹出警报来显示数据已被删除。
*抱歉我的英语不好
*hapus 技术上意味着破坏
this the code:
这是代码：
public function hapus(Request $request, $id)
{
DB::table('kelompok')
->where('id', $id)
->delete();
return redirect()->back();
}

Use with()in your controller
with()在您的控制器中使用
function hapus(Request $request, $id)
{
DB::table('kelompok')
->where('id', $id)
->delete();
return redirect()->back()->with('alert', 'Deleted!');
}
In your blade template, retrieve the sessionafter being redirected from controller:
在您的刀片模板中，session从控制器重定向后检索：
@if (session('alert'))
<div class="alert alert-success">
{{ session('alert') }}
</div>
@endif

Extending @pbwned's answer,
you can also use javascript alert boxin your blade view to display the flash session/message.
扩展@pbwned 的回答，您还可以alert box在刀片视图中使用 javascript来显示 Flash 会话/消息。
For example:
例如：
<script>
var msg = '{{Session::get('alert')}}';
var exist = '{{Session::has('alert')}}';
if(exist){
alert(msg);
}
</script>
Hope it helps =)
