rkgrep / attributable by rkgrep

Attributable

Note: Original idea by Taylor Otwell in Laravel Framework.

The package includes traits which allow fluent and elegant way to work with internal object property arrays.

Installation

Install the package with composer.

composer require rkgrep/attributable

Apply the trait to any class you need.

class Foo {
    
    use rkgrep\Attributable;
    
}

class Bar {
    
    use rkgrep\Fillable;
    
}

Usage

Attributable trait

Attributable provides different access and assignment ways.

Assign internal variables via property or method call

$foo->var1 = 1;
$foo->var2(2);

Access variables via property

echo $foo->var1;
echo $foo->var2;

Provide fallback value via get method

$foo->get('var4', 'fallback');
$foo->get('var5', function() { return 'closure result'; });

Get all internal variables via getAttributes method

$all = $foo->getAttributes();

Method call without arguments assigns true

$foo->viewable();
true == $foo->viewable;

Chain methods for fast assignment

$user->first_name('John')->last_name('Doe')->admin();

Fillable trait

Fillable provides chaining assignment of variables or groups of variables.

Mass assign atributes with fill method

$user->fill(['name' => 'Admin', 'email' => 'admin@example.com']);

Overwrite or reassign control via second parameter

$user->fill(['name' => 'John Doe']); // Name changed, email remains untouched
$user->fill(['email' => 'other@example.com'], false); // Disabled merging - old values are dropped

Fill specific properties with with method

$user->with('password', md5('password'));

Prevent overriding with third parameter

$user->with('password', '', false); // Password remains untouched

Assign multiple variables

$user->with(['friends' => ['Mike', 'Dave'], 'girlfriend' => 'Jane']);
$user->with(['siblings' => [], 'girlfriend' => 'Mary'], null, false); // Overriding disabled - only siblings are touched

Chain method calls

$post->fill(['title' => 'Lorem Ipsum'])->with('views', 5)->with('likes', 3);

Interfaces

Any class with Attributable trait applied implements ArrayAccess and JsonSerializable. If you use illuminate/support package you can also apply Arrayable and Jsonable interfaces.

class Bar implements ArrayAccess, JsonSerializable, Arrayable, Jsonable {

    use rkgrep\Attributable;

}

$bar = new Bar();
$bar->value('test');

$arrayValue = $bar['value'];
$bar['value'] = 'new';
$json = json_encode($bar); // returns '{"value": "new"}'

$array = $bar->toArray();
$json = $bar->toJson();
