How To Bootstrap Tags System In Laravel 8?

Hi Friends,

This example is how to bootstrap tags system in laravel 8?.

This example is short code and easy way to understand in users.

You will learn how to create a tag system in the Laravel 8 application using the laravel-tagging package.

So let's start following step.

Step 1 - Download New Freash Laravel Application

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

Move into the project’s root.

cd laravel-tag-blog

Step 2 - Add Database Details

The database is connected to the app by adding database details into the .env configuration files.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=database_user_name
DB_PASSWORD=database_password

Step 3 - Install Laravel Tagging Package

Next, open the terminal add the command to install the laravel tagging package; this package offers the tag support for Laravel Eloquent models recklessly.

composer require rtconner/laravel-tagging

Step 4 - Add Tagging Service in Laravel

config/app.php

....
....
'providers' => [
	....
	....

	\Conner\Tagging\Providers\TaggingServiceProvider::class,
	....
	....
]

Step 5 - Publish Tagging Service in Laravel

below command to publish in laravel.

php artisan vendor:publish --provider="Conner\Tagging\Providers\TaggingServiceProvider"

Next, you have to run a command to run the migration for the tags system, and it will generate tagging tables into the database.

php artisan migrate

Step 6 - Create Model and Migration

php artisan make:model TagPost -m

Update code in app/Models/Post.php file.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class TagPost extends Model
{
    use HasFactory;

    use \Conner\Tagging\Taggable;
    
    protected $fillable = [ 
        'title_name', 
        'content' 
    ];
}

Now, get into the app/database/migrations/create_posts_table.php, and you have to insert the table values into this migration file.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateTagPostsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('tag_posts', function (Blueprint $table) {
            $table->id();
            $table->string('title_name');
            $table->text('content');            
            $table->timestamps();
        });
    }

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

Consequently, you have to execute a command to run migrations.

php artisan migrate

Step 7 - Set Up Controller

Let’s generate a new controller with the help of the following command.

php artisan make:controller TagController

app/Http/Controllers/TagController

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\TagPost;

class TagController extends Controller
{
    public function index()
    {
        $tags = TagPost::all();
        return view('tag',compact('tags'));
    }

    public function store(Request $request)
    {
        $this->validate($request, [
            'title_name' => 'required',
            'content' => 'required',
            'tags' => 'required',
        ]);

        $input = $request->all();

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

        $post = TagPost::create($input);

        $post->tag($tags);

        return back()->with('success','Tags added to database.');
    }
}

Step 8 - Create Route

routes/web.php

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\TagController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/show-tags', [TagController::class, 'index']);
Route::post('/create-tags', [TagController::class, 'store']);

Step 9 - Create Blade File

resources/views/tag.blade.php

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

            padding: 3px 7px;
            border-radius: 3px;
        }
        .bootstrap-tagsinput {
            width: 100%;
        }
    </style>
</head>
