change the value of an amount - php

Question

In an html page, I would like to recover the value of an amount and can change the value only in my admin panel.
In the file navbar.blade.php I have 250 which is the amount to edit for the example.
<div class="header-widgets hidden-xs" style="padding:0px;padding-top: 60px;">
<div id="text-3" class="widget widget_text">
<div class="textwidget">
<div class="info-icon">
<img src="/img/time.png">
<span style="font-size: 22px;color: #0d3863;font-weight: bold;"> 250</span>
</div>
</div>
</div>
</div>
I just seek to edit the amount (250) ...
In my Controller named tarrifcontroller I have that.
public function edit(Tariff $tariff)
{
return view('admin.tariffs.edit', compact('tariff'));
}
public function update(Request $request, Tariff $tariff)
{
$tariff->valeur = strip_tags($request->input('amount'));
$tariff->save();
return redirect('/tariffs');
}
In my edit.blade.php I have that
#section('content')
<div class="px-content">
<div class="page-header">
<div class="row">
<div class="col-md-4 text-xs-center text-md-left text-nowrap">
<h1><i class="px-nav-icon ion-android-apps"></i>Tarif {{$tariff->id}} </h1>
</div>
<hr class="page-wide-block visible-xs visible-sm">
<!-- Spacer -->
<div class="m-b-2 visible-xs visible-sm clearfix"></div>
</div>
</div>
<div class="row">
<div class="panel">
<div class="panel-body">
<div class="table-responsive">
<form class="panel-body" action="/tariff/edit/{{$tariff->id}}" method="POST">
#csrf
<fieldset class="form-group">
<label for="form-group-input-1">Amount</label>
<input type="text" name="amount" class="form-control" id="form-group-input-1" value="{{$tariff->amount}}">
</fieldset>
<button type="submit" class="btn btn-primary pull-right">MAJ</button>
</form>
</div>
</div>
</div>
</div>
</div>
#endsection
My problem is now in navbar.blade.php how should I do that 250 can interact with my edit / update function?
<span style="font-size: 22px;color: #0d3863;font-weight: bold;"> 250</span>
Thank you

I don't have experience with laravel but i guess like any other php framework you can echo variable from controller to view
<span style="font-size: 22px;color: #0d3863;font-weight: bold;"> <?php echo $variable ?></span>
after some googling: You can pass data to the view using the with method.
return View::make('blog')->with('posts', $posts);
