将成功失败状态从控制器传递到刀片/视图

问题描述

我们如何将成功失败状态和一些消息从控制器传递到 Blade 文件？

控制器

public function store(Request $request)
{
    return redirect()->back()->with('failure','File uploaded Successfully');
}

刀片/视图

@if (session()->has('failure'))
    <div class="alert alert-danger">
         {{ session()->has('failure') }}
    </div>
@endif

解决方法

控制器：

public function store(Request $request){
    return redirect()->back()->with('failure','File uploaded failed!');
}

刀片：

@if (session()->has('failure'))
    <div class="alert alert-danger">
         {{ session()->get('failure') }}
    </div>
@endif

,

在控制器的函数中添加这一行

session()->flash('success','File uploaded Successfully');

并在视图中放置此代码

@if (session()->has('failure'))
<div class="alert alert-danger">
     {{ session()->get('failure') }}
</div>@endif
