Installation

Install the package via Composer:

composer require abdylreshit/laravel-eav

The package will auto-discover and register its service provider.

Configuration

Publish the migration:

php artisan vendor:publish --provider="Abdylreshit\LaravelEav\Providers\LaravelEavServiceProvider" --tag="migrations"

Run the migration:

php artisan migrate

This creates the necessary tables: attributes and attribute_values.

Quick Start

1. Add the Trait to Your Model

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Abdylreshit\LaravelEav\Traits\HasEavAttributes;

class Product extends Model
{
    use HasEavAttributes;
}

2. Create Attributes

use Abdylreshit\LaravelEav\Models\Attribute;
use Abdylreshit\LaravelEav\Enums\AttributeType;

// Create a color attribute
Attribute::create([
    'name' => 'Color',
    'code' => 'color',
    'type' => AttributeType::STRING,
]);

// Create a price attribute
Attribute::create([
    'name' => 'Price',
    'code' => 'price',
    'type' => AttributeType::DECIMAL,
]);

3. Use Attributes on Your Model

$product = Product::find(1);

// Set a single attribute
$product->setAttribute('color', 'red');

// Set multiple attributes
$product->setAttributes([
    'color' => 'blue',
    'price' => 99.99,
    'in_stock' => true,
]);

// Get an attribute
$color = $product->getAttribute('color'); // 'blue'

// Get multiple attributes
$attrs = $product->getAttributes(['color', 'price']);

// Get all attributes
$allAttrs = $product->getAllAttributes();

// Check if attribute exists
if ($product->hasAttribute('color')) {
    // ...
}

// Delete an attribute
$product->deleteAttribute('color');

Querying with Attributes

Filter models by attribute values:

// Find products with a specific color
$redProducts = Product::whereAttribute('color', 'red')->get();

// Find products by multiple attributes
$products = Product::whereAttributes([
    'color' => 'blue',
    'in_stock' => true,
])->get();

// Combine with other queries
$products = Product::where('category_id', 1)
    ->whereAttribute('price', '>', 50)
    ->get();

Attribute Types

The package supports the following attribute types:

Define Attribute Type

use Abdylreshit\LaravelEav\Enums\AttributeType;

Attribute::create([
    'name' => 'Description',
    'code' => 'description',
    'type' => AttributeType::TEXT,
]);

Attribute::create([
    'name' => 'Launch Date',
    'code' => 'launch_date',
    'type' => AttributeType::DATETIME,
]);

Translatable Attributes

Attribute names are translatable out of the box:

$attribute = Attribute::create([
    'name' => ['en' => 'Color', 'fr' => 'Couleur'],
    'code' => 'color',
    'type' => AttributeType::STRING,
]);

// Get the name in a specific language
$nameEn = $attribute->getTranslation('name', 'en'); // 'Color'
$nameFr = $attribute->getTranslation('name', 'fr'); // 'Couleur'

Eager Loading

Eager load EAV values with your model to avoid N+1 queries:

// Eager load all EAV values
$products = Product::with('eavValues.attribute')->get();

foreach ($products as $product) {
    $color = $product->getAttribute('color'); // No additional query
}

Validation

Validate EAV attributes in your request:

use Abdylreshit\LaravelEav\Models\Attribute;

$validated = $request->validate([
    'name' => 'required|string',
    'color' => 'nullable|string|max:50',
    'price' => 'nullable|numeric|min:0',
]);

$product = Product::create($validated);
$product->setAttributes($validated);

Available Methods

Getting Attributes

• getAttribute(string $code) - Get a single attribute value
• getAttributes(array $codes) - Get multiple attribute values
• getAllAttributes() - Get all attributes as an array
• hasAttribute(string $code) - Check if attribute exists

Setting Attributes

• setAttribute(string $code, $value) - Set a single attribute
• setAttributes(array $attributes) - Set multiple attributes

Deleting Attributes

• deleteAttribute(string $code) - Delete an attribute value

Querying

• whereAttribute(string $code, $value) - Filter by single attribute
• whereAttributes(array $attributes) - Filter by multiple attributes

Relationships

• eavValues() - MorphMany relationship to attribute values

Database Schema

Attributes Table

Examples

E-Commerce Product Catalog

// Create attributes for a shoe product
Attribute::create(['name' => 'Size', 'code' => 'size', 'type' => AttributeType::STRING]);
Attribute::create(['name' => 'Color', 'code' => 'color', 'type' => AttributeType::STRING]);
Attribute::create(['name' => 'Material', 'code' => 'material', 'type' => AttributeType::STRING]);

// Set attributes on a product
$shoe = Product::find(1);
$shoe->setAttributes([
    'size' => '42',
    'color' => 'black',
    'material' => 'leather',
]);

// Query products
$blackShoes = Product::whereAttribute('color', 'black')->get();

CMS Page Attributes

// Create attributes for a page
Attribute::create(['name' => 'Author', 'code' => 'author', 'type' => AttributeType::STRING]);
Attribute::create(['name' => 'SEO Title', 'code' => 'seo_title', 'type' => AttributeType::STRING]);
Attribute::create(['name' => 'Published Date', 'code' => 'published_date', 'type' => AttributeType::DATE]);

// Use on your Page model
$page = Page::find(1);
$page->setAttributes([
    'author' => 'John Doe',
    'seo_title' => 'Best Laravel Tips',
    'published_date' => now()->format('Y-m-d'),
]);

Performance Tips

1. Use Eager Loading - Always eager load EAV values when querying multiple models
2. Index the code Column - Add a database index to attributes.code for faster queries
3. Cache Attributes - Cache commonly used attributes
4. Batch Operations - Use batch setting/getting instead of individual calls

Console Commands

Publish Assets

php artisan eav:publish

Publishes migrations and configuration files.

Migrate EAV Tables

php artisan eav:migrate

Runs EAV-specific migrations.

Troubleshooting

Attribute Not Found

Ensure the attribute exists before setting a value:

$attribute = Attribute::where('code', 'color')->first();
if (!$attribute) {
    Attribute::create([...]);
}

N+1 Query Problem

Use eager loading:

$products = Product::with('eavValues.attribute')->get();

Type Mismatch

Ensure the value type matches the attribute type:

$price = Attribute::where('code', 'price')->first();
// $price->type will be AttributeType::DECIMAL
// Always pass numeric values for decimal attributes
