Laravel Taggify - Eloquent Tagging Package

This package will allow user to add Tagging system in the Laravel 7 application.

You can provide combination of string or id or model to create tags. It will check if a tag is already exists in the tags table. If not it will create a new tag and attach with the model. It also comes with some useful helpers and Scopes.

Composer Install

composer require amitkolloldey/laravel-taggify

Run the migrations

Migrate The database tables

php artisan migrate

It will migrate tags , taggables tables

Setup your models

To creat a many to many polymorphic relation with your model and tags you need to use the Taggify trait.

<?php

namespace App;

use AmitKD\LaravelTaggify\Taggify;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use Taggify;

    protected $fillable = [
        'title'
    ];
}

Usage

To attach/create new tags it uses addTags method. This method takes an array containing models or id or name of the tags you want to attach to your model and of course you can all use combination of these.

Attaching or Creating tags

<?php

 $post = \App\Post::findOrFail(2);
 $post->addTags( [ 'Non Existing Tag', 'Spring Framework', 'Java']);

<?php

 $post = \App\Post::findOrFail(2);
 $tag = Tag::findOrFail(7);
 $post->addTags( [ $tag, 8, 9, 'Java']); // Tag model/ids/name

The name will generate a unique slug for the tag and will increment the count column. The count column will represent how many times the tag's being used.

Detaching given tags

<?php

 $post = \App\Post::findOrFail(2); 
 $tag = Tag::findOrFail(7);
 $post->removeTags([ $tag, 8, 9, 'Java']);

The remove tags will detach the given tags and decrement the count column.

Detaching all tags

<?php

 $post = \App\Post::findOrFail(2); 
 $post->removeAllTags();

It will detach all the tags associated with the model and decrement the count column.

Re tag

<?php

 $post = \App\Post::findOrFail(2); 
 $post->reTag(['Python','PHP','php oop']);

It will detach Previous Tags and attach Given Tags and decrement the count column.

Scopes

withAnyTag

<?php

 $posts = Post::withAnyTag(['Laravel','Java', 9])->get()->dd();

Gets The Models Associated with Any Given Tags.

withAllTags

<?php

 $posts = Post::withAllTags(['Laravel','Java', 9])->get()->dd();

Finds The Models Where Given All Tags Are In Common.

unPopular

<?php

 Tag::unPopular(5)->get()->dd(); // 5 is how many tags to display

Gets Less Used Tags based on count column.

unUsed

<?php

 Tag::unUsed(5)->get()->dd(); // 5 is how many tags to display

Gets Unused Tags based on count column.

usedMoreThan

<?php

 Tag::usedMoreThan(5)->take(5)->get()->dd(); ; // more then 5 times tag's being used

Return tags that are used more than given times based on count column.

usedLessThan

<?php

 Tag::usedLessThan(5)->take(5)->get()->dd(); // not more then 5 times tag's being used

Return tags that are used less than given times based on count column.

Helpers

The package comes with 2 useful helpers, which you can use throughout your application.

popular_tags_by_model

  <ul>
     @foreach (popular_tags_by_model("App\Post") as $popular_tag)
      <!-- Model class, number of items to take --> 
          <li>
              <p>{{$popular_tag->tag_id}}</p>
              <p>{{$popular_tag->tag_name}}</p>
              <p>{{$popular_tag->tag_slug}}</p>
              <p>{{$popular_tag->model_count}}</p>
              <p>{{$popular_tag->tag_description}}</p> 
          </li>
     @endforeach
  </ul>

Gets Popular Tags In A Specific Model.

popular_tags

  <ul>
     @foreach (popular_tags(5) as $popular_tag) 
          <!-- number of items to take --> 
          <li>
              <p>{{$popular_tag->id}}</p>
              <p>{{$popular_tag->slug}}</p>
              <p>{{$popular_tag->name}}</p>
              <p>{{$popular_tag->count}}</p>
              <p>{{$popular_tag->description}}</p> 
          </li>
     @endforeach
  </ul>

Inverse Relation in Tag Model

use items() method and give a model

<?php

 $tag = Tag::findOrFail(7);
 $tag = $tag->items(Post::class)->take(5)->get()->dd();

You can also add inverse relationship by extending the AmitKD\LaravelTaggify\Models\Tag model
