An example explains how to implement a navigation bar effect in laravel

Laravel is a very popular PHP framework, in which implementing a navigation bar is an indispensable function for implementing web applications. Through this article, I will introduce you to how to implement the navigation bar in Laravel.

1. Install and configure Laravel
Before you start using Laravel to implement the navigation bar, you need to complete the installation and configuration of Laravel. I won't go into too much detail here, but users who need to learn can check out the official documentation.

2. Creation of the navigation bar
In Laravel, we can implement the navigation bar through custom components. Components are reusable View code that can be used multiple times. Let’s take a look at how to create a custom component!

1. Create a custom component view
First, create the navigation component view navbar.blade.php file in resources/views/components. In the file, we will add some basic HTML markup for the navigation bar and add the content that needs to be displayed.

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
  <a class="navbar-brand" href="#">Laravel</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="#">Home</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">About</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Contact</a>
      </li>
    </ul>
  </div>
</nav>

In this file, we add a NAV tag, set the style, style class and navigation link, so that the navigation bar can be easily displayed in the website.

2. Register custom components
Now let us create a PHP class named Navbar.php in the resources/views/components folder. This class has a create method, which is used to express: build components from the view, and at the same time, private data and configuration can be passed there.

<?php

namespace App\View\Components;

use Illuminate\View\Component;

class Navbar extends Component
{
    public function __construct()
    {
        //
    }

    public function render()
    {
        return view(&#39;components.navbar&#39;);
    }
}

The view of the component has been defined, and now the component needs to be registered in laravel so that Laravel knows how to identify the component.

Open the app/Providers/AppServiceProvider.php file and use the view compositor in the boot method to register the component:

use Illuminate\Support\Facades\Blade;
use App\View\Components\Navbar;

public function boot()
{
    Blade::component('navbar', Navbar::class);
}

Now, we have a name in our application A component called "navbar" that we can use as a marker in any view.

3. Add the navigation bar to the view
Now that the component has been defined, we need to add it to the view. Open the app/resources/views/layouts/app.blade.php file and add the following code:

<x-navbar />
<div class="container py-4">
  @yield('content')
</div>

The navbar component is included in the page header. This line of code added in the HEAD section instructs Laravel to Insert this component into .

4. Navigation bar in the view
Finally, we add some routes to the routes/web.php file to build a simple website and add a navigation bar to it. The specific code is as follows

Route::get('/', function () {
    return view('welcome');
});

Route::get('/about', function () {
    return view('about');
});

Route::get('/contact', function () {
    return view('contact');
});

The complete navigation bar code is as follows:

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
  <a class="navbar-brand" href="#">Laravel</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
      <li class="nav-item">
        <a class="nav-link" href="/">Home</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="/about">About</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="/contact">Contact</a>
      </li>
    </ul>
  </div>
</nav>

After successfully implementing the navigation bar, we can see it at the top of each page of the website, making the navigation of the website More advanced and clearer logic.

Summary
Through the implementation of the above custom components, you can easily create a navigation bar in Laravel to make the website more readable and accessible. Even if you are a beginner in developing Laravel, you can easily implement a navigation bar on your own.
