README

A simple package for tagging Eloquent models in Laravel. This package is a sibling of Laravel Categories, which can be used to categorise Eloquent models. The API is the same as this one.

Installation

1. Install using Composer

composer require robotsinside/laravel-tags

1. Register the service provider in config/app.php

/*
* Package Service Providers...
*/
\RobotsInside\Tags\TagsServiceProvider::class,

Auto-discovery is enabled, so this step can be skipped.

1. Publish the migrations

php artisan vendor:publish --provider="RobotsInside\Tags\TagsServiceProvider" --tag="migrations"

1. Migrate the database. This will create two new tables; tags and taggables

php artisan migrate

Usage

Use the RobotsInside\Tags\Taggable trait in your models.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use RobotsInside\Tags\Taggable;

class Post extends Model
{
    use Taggable;
}

You are now ready to start tagging. Models can be tagged by passing an integer, array of integers, a model instance or a collection of models.

<?php

use App\Post;
use Illuminate\Support\Facades\Route;
use RobotsInside\Tags\Models\Tag;

Route::get('/', function () {

    // Retrieve a new or existing tag
    $tag1 = (new Tag())->resolve('Tag 1');
    $tag2 = (new Tag())->resolve('Tag 2');

    // Or, retrieve a collection of new or existing tags
    $tags = (new Tag())->resolveAll(['Tag 1', 'Tag 2', 'Tag 3'])

    $post = new Post();
    $post->title = 'My blog';
    $post->save();

    $post->tag($tag1);
    // Or
    $post->tag(['tag-1']);
    // Or
    $post->tag([1, 2]);
    // Or
    $post->tag(Tag::get());
});

Untagging models is just as simple.

<?php

use App\Post;
use Illuminate\Support\Facades\Route;
use RobotsInside\Tags\Models\Tag;

Route::get('/', function () {

    $tag1 = Tag::find(1);

    $post = Post::where('title', 'My blog')->first();

    $post->untag($tag1);
    // Or
    $post->untag(['tag-1']);
    // Or
    $post->untag([1, 2]);
    // Or
    $post->untag(Tag::get());
    // Or
    $post->untag(); // remove all tags
});

Scopes

Each time a RobotsInside\Tags\Models\Tag is used, the count column in the tags table is incremented. When a tag is removed, the count is decremented until it is zero.

This packages comes with a number of pre-defined scopes to make queries against the count column easier, namely >=, >, <= and < contstrains, for example:

• Tag::usedGte(1);
• Tag::usedGt(2);
• Tag::usedLte(3);
• Tag::usedLt(4);

In addition, a scope on the Taggable model is provided to constrain records created within the given time frame. This scope supports human readable values including days, months and years in both singular and plural formats, for example:

• Taggable::taggedWithin('7 days');
• Taggable::taggedWithin('1 month');
• Taggable::taggedWithin('2 years');
