Triple Pivot
============

[](#triple-pivot)

**This package is not maintained anymore, let me know if you wish to work on it**

A way to link 3 many-to-many relations together in Laravel 4's Eloquent.

Contents

[](#contents)

### Usage

[](#usage)

### Setup

[](#setup)

1. Create 3 models: User, Tag, Track
2. Set up your tables: users, tags, tracks, pivot table (defaults to tag\_track\_user, in the example below we use custom name users\_tags\_tracks)
3. Require in `composer.json` and `config/app.php`
4. Add the trait in all 3 models
5. Define the relation method as `->tripleBelongsToMany()`
6. (Optional) Create a nice-name relation for the `->third()` method

---

Usage
-----

[](#usage-1)

```
// Get the first User, and autoload their tags
$user = User::with( 'tags' )->first();

// Like an ordinary belongsToMany
$user->tags; // Collection of tags
$user->tags->first(); // Tag model

// Get the track associated with a given tag for the user
$user->tags->first()->third; // Track model
$user->tags->first()->track; // Track model (only if you did step 6)

// Attach a tag/track to a user
$user->tags()->attach( [ $tagId, $trackId ] ); // Pass an array of 2 IDs
$user->tags()->attach( [ Tag::find( $tagId ), Track::find( $trackId ) ] ); // Pass an array of 2 models

```
