Answer 1

Use withErrors() instead of with使用withErrors()而不是with

return Redirect()->back()->withErrors(['count' => 'Invalid credentials']);

In Blade在刀片

if ($errors->has('count')) {
    echo 'message';
}

If you need to redirect with inputs then use withInput()如果您需要使用输入重定向，请使用withInput()

Controller Controller

   public function login(UserRequest $request){
    $this->repository->pushCriteria(new WhereCriteria('email',$request->email));
    $this->repository->pushCriteria(new WhereCriteria('password',$this->binaryPassword($request->password)));
    $data = $this->repository->get();
    if(count($data) < 1){
       return  redirect()->back()->with('errors','Invalid credentials');
    }
    redirect('/dashboard');
}

Blade刀

@if (session('errors'))
<div class="alert alert-success">
    {{ session('errors') }}
</div>
@endif
