Simple Tags System Example in Laravel

Preview:

Step 1 : Install Laravel

In first step, If you haven’t install laravel then we require to get fresh Laravel application using bellow command, So open your terminal OR command prompt and run bellow command:

composer create-project --prefer-dist laravel/laravel blog

Step 2: Install rtconner/laravel-tagging Composer Package

In this step, we require to install “rtconner/laravel-tagging” composer package for add tags. so let’s run bellow command:

composer require composer require rtconner/laravel-tagging

After successfully install package, open config/app.php file and add service provider.

config/app.php

'providers' => [
	....
	ConnerTaggingProvidersTaggingServiceProvider::class,
]
......

After register provider, we require to make public configuration and then run migration for tags tags, so let’s run bellow both command.

php artisan vendor:publish --provider="ConnerTaggingProvidersTaggingServiceProvider"

For run migration:

php artisan migrate

Step 3: Create articles table and model

here you have to create articles table in your database. First create migration for articles table using Laravel 5 php artisan command, so first run bellow command:

php artisan make:migration create_articles_table

After run above command, you will see a migration file in following path database/migrations and you have to simply put following code in migration file to create articles table.

<?php

use IlluminateSupportFacadesSchema;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;

class CreateArticlesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('articles', function (Blueprint $table) {
            $table->increments('id');
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('articles');
    }
}

Run migration file and run following command:

php artisan migrate

After create ‘articles’ table, we should create model for articles table. Create file in following path app/Article.php and put bellow couple of code in Article.php file:

app/Article.php

<?php

namespace App;

use IlluminateDatabaseEloquentModel;

class Article extends Model
{
	use ConnerTaggingTaggable;

    protected $fillable = [ 'title', 'body' ];
}

Step 4: Add New Routes

Here we will create route for article listing and create post article. so open your routes/web.php file and add following route.

routes/web.php

Route::get('article', 'ArticleController@index');
Route::post('article', 'ArticleController@store');

Step 5: Create ArticleController Controller

In this point, now we should create new controller as ArticleController. in this controller we write two method, index() and store(). Using this two method we handle both routes. So let’s create ArticleController like as bellow:

app/Http/Controllers/ArticleController.php

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppArticle;

class ArticleController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return IlluminateHttpResponse
     */
    public function index()
    {
    	$articles = Article::all();
        return view('article',compact('articles'));
    }

    /**
     * Show the application dashboard.
     *
     * @return IlluminateHttpResponse
     */
    public function store(Request $request)
    {
    	$this->validate($request, [
            'title' => 'required',
            'body' => 'required',
            'tags' => 'required',
        ]);

    	$input = $request->all();
    	$tags = explode(",", $request->tags);

    	$article = Article::create($input);
    	$article->tag($tags);

        return back()->with('success','Article created successfully.');
    }
}

Step 7: Create article.blade.php View

In Last step, let’s create article.blade.php(resources/views/article.blade.php) for layout and we will display all article and create article form,so put following code:

resources/views/article.blade.php

<!DOCTYPE html>
<html>
<head>
	<title>Article Lists</title>
	<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" />
	<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-tagsinput/0.8.0/bootstrap-tagsinput.css" />
	<script src="http://demo.onlinecode/plugin/jquery.js"></script>
	<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-tagsinput/0.8.0/bootstrap-tagsinput.js"></script>
</head>
<body>

<div >
	<h1>Add Article</h1>

	@if(Session::has('success'))
    <div >
        {{ Session::get('success') }}
        @php
        Session::forget('success');
        @endphp
    </div>
    @endif

	<form action="{{ url('article') }}" method="POST">
		{{ csrf_field() }}
		<div >
			<label>Title:</label>
			<input type="text" name="title"  placeholder="Title">
			@if ($errors->has('title'))
                <span >{{ $errors->first('<title></title>') }}</span>
            @endif
		</div>

		<div >
			<strong>Body:</strong>
			<textarea  name="body" placeholder="Body"></textarea>
			@if ($errors->has('body'))
                <span >{{ $errors->first('body') }}</span>
            @endif
		</div>

		<div >
			<label>Tags:</label>
			<br/>
			<input data-role="tagsinput" type="text" name="tags" >
			@if ($errors->has('tags'))
                <span >{{ $errors->first('tags') }}</span>
            @endif
		</div>		

		<div >
			<button >Submit</button>
		</div>
	</form>

	<h1>Article Lists</h1>
	@if($articles->count())
		@foreach($articles as $key => $article)
			<h3>{{ $article->title }}</h3>
			<p>{{ $article->body }}</p>
			<div>
				<strong>Tag:</strong>
				@foreach($article->tags as $tag)
					<label >{{ $tag->name }}</label>
				@endforeach
			</div>
		@endforeach
	@endif
</div>

</body>
</html>

Now we are ready to run our example so you can open bellow URL on your browser:

http://localhost:8000/article

you can get more information about “rtconner/laravel-tagging” package from here : rtconner/laravel-tagging.
