Create a CRUD Application with Laravel 5.2 part-4
<?php echo $var; ?>
Now back to our view; first of all, we need to create a view file at /resources/views/users/index.blade.php, as our statement would return the view file from users.index. We are passing a compact users array to this view. So here is our index.blade.php file:
@section('main')
<h1>All Users</h1>
<p>{{ link_to_route('users.create', 'Add new user') }}</p>
@if ($users->count())
<table class="table table-striped table-bordered">
<thead>
<tr>
<th>Username</th>
<th>Password</th>
<th>Email</th>
<th>Phone</th>
<th>Name</th>
</tr>
</thead>
<tbody>
@foreach ($users as $user)
<tr>
<td>{{ $user->username }}</td>
<td>{{ $user->password }}</td>
<td>{{ $user->email }}</td>
<td>{{ $user->phone }}</td>
<td>{{ $user->name }}</td>
<td>{{ link_to_route('users.edit', 'Edit', array($user->id), array('class' => 'btn btn-info')) }}</td>
<td>
{{ Form::open(array('method'
=> 'DELETE', 'route' => array('users.destroy', $user->id))) }}
{{ Form::submit('Delete', array('class' => 'btn btn-danger')) }}
{{ Form::close() }}
</td>
</tr>
@endforeach
</tbody>
</table>
@else
There are no users
@endif
@stop
Let’s see the code line by line. In the first line we are extending the user layouts via the Blade template syntax @extends. What actually happens here is that Laravel will load the layout file at /app/views/layouts/user.blade.php first.
Here is our user.blade.php file’s code:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.1/css/bootstrap-combined.min.css" rel="stylesheet">
<style>
table form { margin-bottom: 0; }
form ul { margin-left: 0; list-style: none; }
.error { color: red; font-style: italic; }
body { padding-top: 20px; }
</style>
</head>
<body>
<div class="container">
@if (Session::has('message'))
<div class="flash alert">
<p>{{ Session::get('message') }}</p>
</div>
@endif
@yield('main')
</div>
</body>
</html>
Now in this file we are loading the Twitter bootstrap framework for styling our page, and via yield('main') we can load the main section from the view that is loaded. So here when we load http://localhost/laravel/public/users, Laravel will first load the users.blade.php layout view and then the main section will be loaded from index.blade.php.
Now when we get back to our index.blade.php, we have the main section defined as @section('main'), which will be used by Laravel to load it into our layout file. This section will be merged into the layout file where we have put the @yield ('main') section.

We are using Laravel’s link_to_route method to link to our route, that is, /users/create. This helper will generate an HTML link with the correct URL. In the next step, we are looping through all the user records and displaying it simply in a tabular format. Now if you have followed everything, you will be greeted by the following screen:
