Plugin for CakePHP 3.x that enables automatic, configurable slugging of database fields

WHY?

Because slugs are great for human-readable yet seo-friendly page titles, urls, image urls, etc! They're pretty much the standard nowadays and CakePHP makes it super easy to give your app the power to create them for you.

HOW?

Just add the Sluggable.Sluggable behaviour to any model whose field(s) you need to slug. See the usage section for customization.

• PHP 5.4+
• CakePHP 3.x

4. Contributing

1. Composer Install
2. Manual Install
3. Loading the plugin in your app
4. Setting up the namespace / autoloader

This plugin is on Packagist which means it can be easily installed with Composer.

composer require cwbit/cakephp-sluggable

Then simply load the plugin normally in your config/bootstrap.php file

# in ../config/bootstrap.php - right after Plugin::load('Migrations') is fine!
Plugin::load('Sluggable');

You can also manually load this plugin in your App

Add the source code in this project into plugins/Sluggable

Then configure your App to actually load this plugin

# in ../config/bootstrap.php
Plugin::load('Sluggable');

Tell the autoloader where to find your namespace in your composer.json file

	(..)
    "autoload": {
        "psr-4": {
           (..)
            "Sluggable\\": "./plugins/Sluggable/src"
        }
    },
    (..)

Then you need to issue the following command on the commandline

	php composer.phar dumpautoload

If you are unable to get composer autoloading to work, add 'autoload' => true line in your bootstrap.php Plugin::load(..) command (see loading section)

The sluggable behavior is extremely easy to implement, simply add it, like any other behavior, to your Table

class PostsTable extends Table
{
	public function initialize(array $options)
	{
		parent::initialize($options);
		
		$this->addBehavior('Sluggable.Sluggable');
	}
}

By default the plugin will automatically generate a slug based on name, will store it in a column called slug and will use a dash - replacement, and will NOT automatically overwrite the slug field whenever name changes.

All of these settings are, of course, configurable.

• pattern
  • :name (default)
  • a \Cake\Utility\Text::insert()-friendly tokenized string. any of the entity fields are valid options
• field
  • slug (default)
  • field in the entity to store the slug
• replacement
  • - (default)
  • string used to replace spaces when building the slug
• overwrite
  • false (default)
  • true, if the slug should ALWAYS be re-generated on save. false, to generate once

Generate a slug based on the title field instead of name

class PostsTable extends Table
{
	public function initialize(array $options)
	{
		parent::initialize($options);
		
		$this->addBehavior('Sluggable.Sluggable', [
			'pattern' => ':title',
		]);
	}
}

Generate a slug based on id and title

class PostsTable extends Table
{
	public function initialize(array $options)
	{
		parent::initialize($options);
		
		$this->addBehavior('Sluggable.Sluggable', [
			'pattern' => ':id-:title',
		]);
	}
}

Generate a slug based on the latest version of the title (always)

class PostsTable extends Table
{
	public function initialize(array $options)
	{
		parent::initialize($options);
		
		$this->addBehavior('Sluggable.Sluggable', [
			'pattern' => ':title',
			'overwrite' => true,
		]);
	}
}

Generate a slug normally, but store it in the foo column

class PostsTable extends Table
{
	public function initialize(array $options)
	{
		parent::initialize($options);
		
		$this->addBehavior('Sluggable.Sluggable', [
			'field' => 'foo',
		]);
	}
}

Generate a slug using . dots instead of - dashes

class PostsTable extends Table
{
	public function initialize(array $options)
	{
		parent::initialize($options);
		
		$this->addBehavior('Sluggable.Sluggable', [
			'replacement' => '.',
		]);
	}
}

The Sluggable Plugin adds a Utility class Slug that can be called statically. This is the function used by the Behavior to actually generate the slug.

It is capable of handling a string, array, or entity in conjunction with a simple string or Text::insert-friendly pattern.

To use the Utility, simply add the following to your class header

	use Sluggable\Utility\Slug;

The Utility provides the following function

 /**
     * Turns a string (and optionally a dynamic, data-injected string) into a slugged value
     * @param $pattern string a simple string (e.g. 'slug me') 
     * 						  or Text::insert-friendly string (e.g. ':id-:name')
     * @param $data mixed an Array or Entity of data to Text::insert inject into $pattern
     * @param $replacement string the character to replace non-slug-friendly characters with (default '-')
     * @return string the slugged string
     */
    Slug::generate($pattern, $data = [], $replacement = '-');

	use Sluggable\Utility\Slug;

	echo Slug::generate('slug me');
	# 'slug-me'

	echo Slug::generate('SLUG(!@#(ME');
    # 'slug-me'

    echo Slug::generate('a really long slug that i just made');
    # 'a-really-long-slug-that-i-just-made'

To Text::insert via an array...

	$data = [
		'id' => 123,
		'name' => 'abc',
		'description' => 'Hello, World!',
	];

	$slug = Slug::generate(':id-:name', $data);
	# '123-abc'

	$slug = Slug::generate(':description', $data);
	# 'hello-world'

To Text::insert via Entity properties...

	$data = new Entity([
		'id' => 123,
		'name' => 'abc',
		'description' => 'Hello, World!',
	]);

	$slug = Slug::generate(':id-:name', $data);
	# '123-abc'

	$slug = Slug::generate(':description', $data);
	# 'hello-world'
