No further development or bug fixes will happen. Prologue Support is an extension for [Illuminate Support](https://github.com/illuminate/support). It provides you with extra helper functionality for your application. Maintained by [Cristian Tabacitu](https://github.com/tabacitu) Table of Contents ----------------- [](#table-of-contents) - [Installation](#installation) - [Usage](#usage) - [Collection](#collection) - [MessageBag](#messagebag) - [Helper Functions](#helper-functions) - [Changelog](#changelog) - [License](#license) Installation ------------ [](#installation) You can install Prologue Support for your project through Composer. Require the package in your `composer.json`. ``` "prologue/support": "dev-master" ``` Run composer to install or update the package. ``` $ composer update ``` Usage ----- [](#usage) ### Collection [](#collection) The `Collection.php` class in Prologue Support comes with some additional functions. #### filterBy($key, $value) [](#filterbykey-value) Used to filter for records which have a specific value set for a given key. ``` $data = array( array('name' => 'foo', 'age' => 21), array('name' => 'bar', 'age' => 20), array('name' => 'baz', 'age' => 9), ); $collection = new Prologue\Support\Collection($data); // Will return only records with an age of 20. $items = $collection->filterBy('age', 20)->all(); ``` #### orderBy($key, $direction) [](#orderbykey-direction) Used to order records by a given key. ``` $data = array( array('name' => 'foo', 'age' => 21), array('name' => 'bar', 'age' => 20), array('name' => 'baz', 'age' => 9), ); $collection = new Prologue\Support\Collection($data); // Will order the records by its age in ascending order. $items = $collection->orderBy('age')->all(); ``` You can also order in a descending way. ``` $items = $collection->orderBy('age', 'desc')->all(); ``` ### MessageBag [](#messagebag) The MessageBag class in Prologue Support offers the ability to add arrays or other MessageBags as messages. ``` $bag = new Prologue\Support\MessageBag; $bag->add('error', array( 'email' => 'Incorrect email address', 'url' => 'Incorrect url', )); $messages = $bag->get('error'); ``` Now `$messages` equals to: ``` array( array( 'email' => 'Incorrect email address', 'url' => 'Incorrect url', ) ); ``` You see? One of the messages is the array we added. The same goes for instances of `Illuminate\Support\MessageBag`. ``` $bag->add('error', new Illuminate\Support\MessageBag); ``` ### Helper Functions [](#helper-functions) #### is\_true($value) [](#is_truevalue) Determine if a value is true. ``` $result = is_true(true) // true $result = is_true(null) // false ``` #### is\_false($value) [](#is_falsevalue) Determine if a value is false. ``` $result = is_false(false) // true $result = is_false(null) // false ``` #### last\_key(array $value) [](#last_keyarray-value) Get the last key from an array. ``` $data = array('foo' => 'bar', 'baz' => 'foz'); $result = last_key($data); // 'baz' ``` Changelog --------- [](#changelog) You view the changelog for this package [here](https://github.com/Prologue/Support/releases).
