Slug

Slugging for CakePHP

Installation

composer require muffin/slug

Load the plugin using the CLI command:

./bin/cake plugin load Muffin/Slug

Usage

To enable slugging add the behavior to your table classes in the initialize() method.

public function initialize(array $config): void
{
    //etc
    $this->addBehavior('Muffin/Slug.Slug', [
        // Optionally define your custom options here (see Configuration)
    ]);
}

Please note that Slug expects a database column named slug to function. If you prefer to use another column make sure to specify the field configuration option.

Searching

If you want to find a record using its slug, a custom finder is provided by the plugin.

// src/Controller/ExamplesController.php
$example = $this->Examples->find('slugged', slug: $slug);

Configuration

Slug comes with the following configuration options:

field: name of the field (column) to hold the slug. Defaults to slug.
displayField: name of the field(s) to build the slug from. Defaults to the \Cake\ORM\Table::displayField().
separator: defaults to -.
replacements: hash of characters (or strings) to custom replace before generating the slug.
maxLength: maximum length of a slug. Defaults to the field's limit as defined in the schema (when possible). Otherwise, no limit.
slugger: class that implements the Muffin\Slug\SlugInterface. Defaults to Muffin\Slug\Slugger\CakeSlugger.
unique:: tells if slugs should be unique. Set this to a callable if you want to customize how unique slugs are generated. Defaults to true.
scope: extra conditions used when checking a slug for uniqueness.
implementedEvents: events this behavior listens to. Defaults to ['Model.buildValidator' => 'buildValidator', 'Model.beforeSave' => 'beforeSave']. By default the behavior adds validation for the displayField fields to make them required on record creating. If you don't want these auto added validations you can set implementedEvents to just ['Model.beforeSave' => 'beforeSave'].
onUpdate: Boolean indicating whether slug should be updated when updating record, defaults to false.
onDirty: Boolean indicating whether slug should be updated when slug field is dirty (has a preset value custom value), defaults to false.

Sluggers

The plugin contains two sluggers:

CakeSlugger

The CakeSlugger uses \Cake\Utility\Text::slug() to generate slugs. In the behavior config you can set the slugger key as shown below to pass options to the $options arguments of Text::slug().

'slugger' => [
    'className' => \Muffin\Slug\Slugger\CakeSlugger::class,
    'transliteratorId' => '<A valid ICU Transliterator ID here>'
]

ConcurSlugger

The ConcurSlugger uses concur/slugify to generate slugs. You can use config array similar to the one shown above to pass options to Cocur\Slugify\Slugify's constructor.
