Laravel Sluggable Trait

A trait you can apply to Eloquent models to have slugs automatically generated on save.

Installation

$ composer require martinbean/laravel-sluggable-trait

## Usage

<?php namespace App;

use Illuminate\Database\Eloquent\Model;
use MartinBean\Database\Elouqent\Sluggable;

class Item extends Model {

	use Sluggable;

}

By default, the trait assumes your database has two columns: name and slug. If you need to change these, you can do so via class constants:

<?php namespace App;

use Illuminate\Database\Eloquent\Model;
use MartinBean\Database\Elouqent\Sluggable;

class Item extends Model {

	use Sluggable;

	const SLUGGABLE_SLUG_COLUMN = 'headline';
	const SLUGGABLE_NAME_COLUMN = 'seo_url';

}

### Regenerating Slugs ### By default, the trait will not overwrite slugs if there is already a value in the model's slug column. To override, this feature, the slug column should be set to null prior to calling the model's save function. E.g.

$mymodel->myslugcolumn = '';
$mymodel->save();

### Unique Slugs ###

The trait supports the generation of unique traits by adding a hexidecimal counter to the end of the slug name if the slug already exists. The counter can also be prefixed with a static OR dynamically generated value. To use a static prefix on the counter, in your model use:

<?php namespace App;

use Illuminate\Database\Eloquent\Model;
use MartinBean\Database\Elouqent\Sluggable;

class Item extends Model {

	use Sluggable;

	const SLUGGABLE_SLUG_COLUMN = 'headline';
	const SLUGGABLE_NAME_COLUMN = 'seo_url';
	const SLUGGABLE_UNIQUE_PREFIXER = 'news';

}

To generate a runtime prefix to prepend to the slug counter when generating a unique slug, you may define a function sluggableUniquePrefixer in your model code that may return a value, based on your model's values. For example:

<?php namespace App;

use Illuminate\Database\Eloquent\Model;
use MartinBean\Database\Elouqent\Sluggable;

class Item extends Model {

	use Sluggable;

	const SLUGGABLE_SLUG_COLUMN = 'headline';
	const SLUGGABLE_NAME_COLUMN = 'seo_url';
	// SLUGGABLE_UNIQUE_PREFIXER will be ignored if a sluggableUniquePrefixer method is present
	const SLUGGABLE_UNIQUE_PREFIXER = 'news';  


    public function sluggableUniquePrefixer() {
        if ($this->author)
            return substr($this->author->firstName,0,1).substr($this->author->lastName,0,1);
        return '';
    }

}
