Filterable Package

A Laravel package for filterable traits and classes. This package provides powerful, dynamic query filtering capabilities directly from incoming requests, especially useful when developing flexible and dynamic APIs.

Quick Example

use DevactionLabs\FilterablePackage\Filter;

// In your controller
$products = Product::query()
    ->filtrable([
        // Full-text search across multiple columns (PostgreSQL GIN index support)
        Filter::fullText(['name', 'description', 'sku'], 'search')
            ->setFullTextLanguage('portuguese'),

        // Price range filter
        Filter::between('price', 'price_range'),

        // Multiple categories (comma-separated: ?filter[categories]=1,2,3)
        Filter::in('category_id', 'categories'),

        // Relationship filter with eager loading
        Filter::relationship('brand', 'slug', '=', 'brand')
            ->with(),

        // Advanced: Products with ANY of these tags
        Filter::relationship('tags', 'name')
            ->whereAny([
                ['name', '=', 'sale'],
                ['name', '=', 'featured'],
                ['name', '=', 'new'],
            ])
            ->with(),

        // Date filter with automatic Carbon conversion
        Filter::exact('created_at', 'date')
            ->castDate()
            ->endOfDay(),

        // JSON field filtering (PostgreSQL/MySQL)
        Filter::json('attributes', 'color', '=', 'color')
            ->setDatabaseDriver('pgsql'),
    ])
    ->customPaginate('paginate', 20, [
        'per_page' => request('per_page', 20),
        'sort' => request('sort', '-created_at'),
    ]);

return response()->json($products);

Example Request:

GET /api/products?filter[search]=laptop&filter[price_range]=1000,3000&filter[categories]=1,2&filter[brand]=apple&filter[color]=silver&sort=-price&per_page=50

Generated SQL:

✅ Optimized WHERE clauses
✅ Automatic JOIN for relationships
✅ Eager loading to prevent N+1
✅ PostgreSQL full-text search with GIN indexes (10-100x faster!)
✅ Pagination with sort support

Installation

composer require devaction-labs/filterable-package

Requirements:

PHP 8.3, 8.4, or 8.5
Laravel 11 or 12

Getting Started

1️⃣ Add the Filterable Trait to Your Model

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use DevactionLabs\FilterablePackage\Traits\Filterable;

class Product extends Model
{
    use Filterable;

    // Optional: Map request parameters to database columns
    protected array $filterMap = [
        'search' => 'name',
        'category' => 'category_id',
    ];

    // Optional: Define sortable columns (prevents SQL injection)
    protected array $allowedSorts = ['name', 'price', 'created_at'];

    // Optional: Default sort
    protected string $defaultSort = '-created_at';
}

2️⃣ Use Filters in Your Controller

namespace App\Http\Controllers\Api;

use App\Http\Controllers\Controller;
use DevactionLabs\FilterablePackage\Filter;
use App\Models\Product;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    public function index(Request $request)
    {
        $products = Product::query()
            ->filtrable([
                // Text search with custom LIKE pattern
                Filter::like('name', 'search')
                    ->setLikePattern('{{value}}%'), // Starts with search

                // Price range filter
                Filter::between('price', 'price_range'),

                // Date filter with automatic time handling
                Filter::exact('created_at', 'date')
                    ->castDate()
                    ->endOfDay(),

                // JSON field filtering
                Filter::json('attributes', 'specs.color', 'LIKE', 'color')
                    ->setDatabaseDriver('mysql'),

                // Relationship with eager loading
                Filter::relationship('category', 'slug', '=', 'category')
                    ->with(),

                // Full-text search across multiple columns
                Filter::fullText(['name', 'description'], 'q')
                    ->setFullTextLanguage('portuguese'),
            ])
            ->customPaginate('paginate', $request->input('per_page', 15), [
                'per_page' => $request->input('per_page', 15),
                'sort' => $request->input('sort', '-created_at'),
            ]);

        return response()->json($products);
    }
}

Example Request:

GET /api/products?filter[search]=laptop&filter[price_range]=100,500&filter[category]=electronics&per_page=20&sort=-price

Quick Filter Reference

📚 For detailed explanations of all parameters, see FILTER_REFERENCE.md

Understanding Parameters

Every filter follows this pattern:

Filter::method($attribute, $requestParameter)
//               ↑              ↑
//        database column   URL param name

Example:

Filter::exact('status', 'product_status')

Request:

GET /api/products?filter[product_status]=active
                         ↑ parameter      ↑ value

SQL:

WHERE status = 'active'
      ↑ column  ↑ value

Available Filters

Direct Filters

Basic Comparison Filters

Exact Match: Filter::exact('status', 'status')
Not Equals: Filter::notEquals('status', 'exclude_status')
Greater Than: Filter::gt('amount', 'min_amount')
Greater Than or Equal: Filter::gte('amount', 'min_amount')
Less Than: Filter::lt('amount', 'max_amount')
Less Than or Equal: Filter::lte('amount', 'max_amount')
Between: Filter::between('created_at', 'date_range')

Text Search Filters

LIKE Match: Filter::like('description', 'search')
Case-Insensitive LIKE: Filter::ilike('description', 'search') (Database-specific)
NOT LIKE: Filter::notLike('description', 'exclude_text')
Starts With: Filter::startsWith('name', 'name_prefix')
Ends With: Filter::endsWith('email', 'email_suffix')
Full-Text Search: Filter::fullText(['title', 'content'], 'search') (Database-specific)

Full-Text Search

📚 Complete Full-Text Search Documentation - Includes GIN index setup, performance tips, and all configuration options

The fullText() filter provides powerful text search capabilities that automatically adapt to your database.

Syntax:

Filter::fullText($columns, $requestParameter)
//                ↑              ↑
//        array or string   URL param name

Parameter 1: Columns

Array: Search multiple columns ['title', 'content', 'tags']
String: Single column 'name' or pre-computed 'search_vector'

Parameter 2: Request Parameter

URL parameter name (e.g., 'search', 'q')
Defaults to 'search' if omitted

Database Strategies:

PostgreSQL: Native full-text with to_tsvector, to_tsquery, GIN indexes (10-100x faster)
MySQL/SQLite: Falls back to LIKE across multiple columns

Basic Examples:

// Search across multiple columns
Filter::fullText(['title', 'content', 'tags'], 'search')
//                ↑       ↑          ↑         ↑
//            columns to search      request param

Request: GET /api/posts?filter[search]=laravel framework

Configuration Methods:

1. Language (PostgreSQL only):

Option A: Set via Environment Variable (Recommended)

// Step 1: Add to config/app.php
'fulltext_language' => env('FULLTEXT_LANGUAGE', 'simple'),

// Step 2: Add to .env file
FULLTEXT_LANGUAGE=portuguese

// Step 3: Use without specifying (automatically uses .env value)
Filter::fullText(['title', 'content'], 'q')
// Uses 'portuguese' from .env automatically

Option B: Set Explicitly (Overrides .env)

Filter::fullText(['title', 'content'], 'q')
    ->setFullTextLanguage('portuguese')  // Portuguese stemming
//                         ↑
//                  overrides .env setting

Available: 'simple', 'english', 'portuguese', 'spanish', 'french', etc.

2. Prefix Matching:

Filter::fullText(['name'], 'q')
    ->setFullTextPrefixMatch(false)  // Exact words only (no wildcards)
//                           ↑
//                        true = "test" matches "testing"
//                        false = "test" matches "test" only

High-Performance Setup (PostgreSQL with GIN Index):

// Step 1: Migration - Create search_vector column with GIN index
Schema::table('products', function (Blueprint $table) {
    $table->tsvector('search_vector')->nullable();
});
DB::statement('CREATE INDEX products_search_idx ON products USING GIN(search_vector)');

// Step 2: Use in filter (10-100x faster than regular columns!)
Filter::fullText('search_vector', 'q')
//                ↑
//        pre-computed column (not array)
    ->setDatabaseDriver('pgsql')

Request: GET /api/products?filter[q]=macbook pro

Performance: 5ms vs 500ms on 1M rows (100x faster!)

💡 See FILTER_REFERENCE.md for complete GIN index setup with triggers

List and Array Filters

IN Clause: Filter::in('category_id', 'categories')
NOT IN Clause: Filter::notIn('status', 'exclude_statuses')

Null Value Filters

Is Null: Filter::isNull('deleted_at', 'show_deleted')
Is Not Null: Filter::isNotNull('email_verified_at', 'verified_only')

Database-Specific Behavior

The ilike() filter automatically adapts to your database:

PostgreSQL: Uses native ILIKE operator
SQLite: Falls back to LIKE (case-sensitive)
MySQL: Uses LOWER() function for case-insensitive comparison

// Example usage for case-insensitive search
$filters = [
    Filter::ilike('name', 'search'), // Works across all databases
];

JSON Filters

Exact Match: Filter::json('data', 'user.name', '=', 'user_name')
LIKE Match: Filter::json('data', 'user.name', 'LIKE', 'user_name')

Relationship Filters

Simple Relationship Filter

// Filter posts by user name from request parameter
Filter::relationship('user', 'name', '=', 'user_name')
    ->with(); // Eager load user relationship

Request: ?filter[user_name]=John

Relationship with whereAny (OR logic)

// Products with tags that are EITHER 'sale' OR 'featured'
Filter::relationship('tags', 'name')
    ->whereAny([
        ['name', '=', 'sale'],
        ['name', '=', 'featured'],
    ])
    ->with(); // ✅ Correct - no setValue() needed

Relationship with whereAll (AND logic)

// Users who have BOTH conditions true
Filter::relationship('permissions', 'name')
    ->whereAll([
        ['name', '=', 'edit-posts'],
        ['is_active', '=', true],
    ])
    ->with(); // ✅ Correct - conditions are hardcoded

Relationship with whereNone (NOT logic)

// Posts that have NO banned tags
Filter::relationship('tags', 'is_banned')
    ->whereNone([
        ['is_banned', '=', true],
    ])
    ->with();

Using Dynamic Values in Relationship Conditions

// ✅ CORRECT way to use dynamic values
Filter::relationship('user', 'id')
    ->whereAll([
        ['id', '=', auth()->id()], // Dynamic value in conditions array
        ['active', '=', true],
        ['verified', '=', true],
    ])
    ->with();

// ❌ WRONG - setValue() doesn't work with whereAll/whereAny/whereNone
Filter::relationship('user', 'id')
    ->whereAll([...])
    ->setValue(auth()->id()); // This has no effect!

Customizing Pagination and Sorting

The package provides flexible pagination options through the customPaginate method, supporting three pagination types:

Standard Pagination (with total count)

$results = Expense::query()
    ->filtrable([...])
    ->customPaginate('paginate', 15);

// Returns: total, last_page, current_page, per_page, etc.

Simple Pagination (without total count - better performance)

$results = Expense::query()
    ->filtrable([...])
    ->customPaginate('simple', 15);

// Returns: current_page, per_page, next_page_url, prev_page_url (no total)

Cursor Pagination (most performant for large datasets)

$results = Expense::query()
    ->filtrable([...])
    ->customPaginate('cursor', 15);

// Returns: cursor-based navigation (ideal for infinite scroll)

Custom Parameters

You can pass custom data to append to pagination links:

$results = Expense::query()
    ->filtrable([...])
    ->customPaginate('paginate', 15, [
        'per_page' => 15,
        'sort' => '-created_at'
    ]);

Sorting:

- (minus) prefix indicates descending sorting (e.g., -amount)
Ascending sort uses the field name directly (e.g., amount)

Defining Default Sorting and Allowed Sorts in Model:

protected string $defaultSort = 'amount';
protected array $allowedSorts = ['amount', 'expense_date'];

Custom Filter Mapping

Easily map request parameters to database columns:

protected array $filterMap = [
    'display_name' => 'name',
    'date' => 'expense_date',
];

Now, using the parameter filter[display_name]=John will filter on the name column.

Advanced Features

Date Handling

The Filterable package provides sophisticated date handling capabilities:

// Create a date filter that will convert string dates to Carbon instances
$dateFilter = Filter::exact('created_at')->castDate();

// Apply to a query
$model->filtrable([$dateFilter]);

You can also specify if you want to compare with the start or end of the day:

// Filter by date with time set to 23:59:59
$dateFilter = Filter::exact('created_at')->castDate()->endOfDay();

// Filter by date with time set to 00:00:00
$dateFilter = Filter::exact('created_at')->castDate()->startOfDay();

Custom LIKE Patterns

Customize the pattern used for LIKE filters to match your search requirements:

// Default (contains): '%value%'
$filter = Filter::like('description', 'search');

// Starts with: 'value%'
$filter = Filter::like('description', 'search')->setLikePattern('{{value}}%');

// Ends with: '%value'
$filter = Filter::like('description', 'search')->setLikePattern('%{{value}}');

JSON Field Filtering with Database-Specific Optimizations

The package automatically applies the correct JSON extraction syntax based on your database:

// The query will use the appropriate syntax for your database
$filter = Filter::json('attributes', 'user.age', '>', 'min_age');

// Manually specify database driver if needed
$filter = Filter::json('attributes', 'user.age', '>', 'min_age')->setDatabaseDriver('mysql');

Advanced Relationship Filtering with Conditional Logic

Apply complex conditions to your relationship filters:

// Match if ANY condition is true (OR logic)
$filter = Filter::relationship('user', 'name')
    ->whereAny([
        ['name', '=', 'John'],
        ['email', '=', 'john@example.com'],
    ])
    ->with();

// Match if ALL conditions are true (AND logic)
$filter = Filter::relationship('user', 'name')
    ->whereAll([
        ['name', '=', 'John'],
        ['active', '=', true],
    ])
    ->with();

// Match if NONE of the conditions are true (NOT logic)
$filter = Filter::relationship('user', 'name')
    ->whereNone([
        ['banned', '=', true],
        ['deleted', '=', true],
    ])
    ->with();

Performance Optimizations

The Filterable trait includes several performance optimizations:

Efficient caching of attribute and relationship validations
Optimized handling of relationship filters
Smart deduplication of eager-loaded relationships
Specialized handling for simple equality relationship filters

These optimizations are automatically applied when you use the trait, ensuring your filterable queries remain performant even with complex filter combinations.

                    ->setDatabaseDriver('mysql'),
                
                // Relationship filter with eager loading
                Filter::relationship('category', 'slug', '=', 'category')
                    ->with(), // Eager load this relationship
                
                // Complex relationship filter with conditional logic
                Filter::relationship('tags', 'name')
                    ->whereAny([
                        ['name', '=', 'featured'],
                        ['name', '=', 'sale'],
                    ])
                    ->with()
                    ->setValue('has_special_tag'), // Custom value for this filter
                
                // Multiple criteria for user permissions
                Filter::relationship('user', 'id')
                    ->whereAll([
                        ['active', '=', true],
                        ['role', '=', 'admin'],
                    ])
                    ->setValue(auth()->id()),
            ])
            // Apply pagination with custom parameters
            ->customPaginate('paginate', $request->input('per_page', 15), [
                'per_page' => $request->input('per_page', 15),
                'sort' => $request->input('sort', '-created_at'),
            ]);

        return response()->json($products);
    }
}

Supported Databases for JSON Filters

MySQL
PostgreSQL
SQLite

The package automatically detects the database driver from your configuration.

Practical Examples

Example 1: E-commerce Product Filtering

namespace App\Http\Controllers\Api;

use App\Http\Controllers\Controller;
use App\Models\Product;
use DevactionLabs\FilterablePackage\Filter;
use Illuminate\Http\Request;

class ProductController extends Controller
{
    public function index(Request $request)
    {
        $products = Product::query()
            ->filtrable([
                // Search by name (starts with)
                Filter::like('name', 'search')
                    ->setLikePattern('{{value}}%'),

                // Price range
                Filter::between('price', 'price_range'),

                // Specific categories (multiple)
                Filter::in('category_id', 'categories'),

                // Exclude out of stock
                Filter::notEquals('stock_status', 'exclude_status'),

                // Featured products only
                Filter::exact('is_featured', 'featured'),

                // Filter by brand relationship
                Filter::relationship('brand', 'slug', '=', 'brand')
                    ->with(),

                // Products with ANY of these tags
                Filter::relationship('tags', 'name')
                    ->whereAny([
                        ['name', '=', 'sale'],
                        ['name', '=', 'new'],
                        ['name', '=', 'featured'],
                    ])

                Filter::notIn('id', 'exclude_users'),
            ])
            ->customPaginate('paginate', 15, [

{
    public function index(Request $request)
    {
        $products = Product::query()
            ->filtrable([
                // JSON field filtering - exact match
                Filter::json('specifications', 'dimensions.width', '=', 'width')
                    ->setDatabaseDriver('pgsql'),

                // JSON field - greater than
                Filter::json('specifications', 'weight', '>', 'min_weight')
                    ->setDatabaseDriver('pgsql'),

                // JSON field - LIKE search
                Filter::json('specifications', 'material', 'LIKE', 'material')
                    ->setDatabaseDriver('pgsql'),

                // Multiple JSON paths
                Filter::json('metadata', 'seo.keywords', 'LIKE', 'keywords')
                    ->setDatabaseDriver('mysql'),
            ])
            ->customPaginate('paginate', 20);

        return response()->json($products);
    }
}

Example Requests:

# Filter by JSON fields
GET /api/products?filter[width]=50&filter[min_weight]=2.5

# Search in nested JSON
GET /api/products?filter[material]=cotton&filter[keywords]=organic

Common Mistakes and How to Avoid Them

❌ Mistake 1: Using setValue() with whereAny/whereAll/whereNone

Wrong:

// setValue() has no effect here because conditions are already hardcoded
Filter::relationship('tags', 'name')
    ->whereAny([
        ['name', '=', 'featured'],
        ['name', '=', 'sale'],
    ])
    ->setValue('custom_value') // ❌ This doesn't work
    ->with();

Correct:

// Remove setValue() - the conditions already define what to match
Filter::relationship('tags', 'name')
    ->whereAny([
        ['name', '=', 'featured'],
        ['name', '=', 'sale'],
    ])
    ->with(); // ✅ This works correctly

❌ Mistake 2: Dynamic Values in whereAll

Wrong:

// Trying to use setValue() for dynamic values
Filter::relationship('user', 'id')
    ->whereAll([
        ['active', '=', true],
        ['role', '=', 'admin'],
    ])
    ->setValue(auth()->id()); // ❌ This doesn't filter by user ID

Correct:

// Include dynamic values directly in the conditions array
Filter::relationship('user', 'id')
    ->whereAll([
        ['id', '=', auth()->id()], // ✅ Dynamic value here
        ['active', '=', true],
        ['role', '=', 'admin'],
    ])
    ->with(); // ✅ This works correctly

❌ Mistake 3: Forgetting ->with() for Eager Loading

Wrong:

// Relationship will cause N+1 queries
Filter::relationship('category', 'slug', '=', 'category'); // ❌ Missing ->with()

Correct:

// Eager load the relationship to avoid N+1
Filter::relationship('category', 'slug', '=', 'category')
    ->with(); // ✅ Eager loads the relationship

❌ Mistake 4: Wrong Database Driver for JSON Filters

Wrong:

// Database driver not set - may not work correctly
Filter::json('data', 'user.name', '=', 'name'); // ❌ Driver not set

Correct:

// Always set the database driver for JSON filters
Filter::json('data', 'user.name', '=', 'name')
    ->setDatabaseDriver('pgsql'); // ✅ Driver specified

❌ Mistake 5: Using Between with Non-Array Values

Wrong:

// Between expects array but gets string from request
// Request: ?filter[price_range]=100
$filter = Filter::between('price', 'price_range'); // ❌ Will fail

Correct:

// Request should send comma-separated values
// Request: ?filter[price_range]=100,500
$filter = Filter::between('price', 'price_range'); // ✅ Automatically converts "100,500" to [100, 500]

❌ Mistake 6: Not Using castDate() for Date Filters

Wrong:

// String date won't work with endOfDay()
Filter::exact('created_at', 'date')
    ->endOfDay(); // ❌ Expects Carbon instance

Correct:

// Use castDate() to convert string to Carbon
Filter::exact('created_at', 'date')
    ->castDate() // ✅ Converts to Carbon first
    ->endOfDay(); // ✅ Now this works

✅ Best Practices

Always use ->with() for relationships you need in the response
```
Filter::relationship('user', 'id')->with() // Eager load
```

Set database driver for JSON filters

Filter::json('data', 'path')->setDatabaseDriver(config('database.default'))

Use full-text search for better search experience

Filter::fullText(['title', 'content'], 'search')
    ->setFullTextLanguage('portuguese')

Prefer whereAny/whereAll over multiple separate relationship filters

// Better performance
Filter::relationship('user', 'email')
    ->whereAll([
        ['email', '=', 'test@example.com'],
        ['active', '=', true],
    ])

Use cursor pagination for large datasets

->customPaginate('cursor', 20) // Better performance than 'paginate'

Define allowedSorts in your model to prevent SQL injection

protected array $allowedSorts = ['name', 'created_at', 'price'];
