This package provides a trait that will generate a unique slug when saving any Eloquent model.

NOTE: This package is based on spatie/laravel-sluggable but with some adjustments for me and few improvements. Here's a major changes:

  • Added the ability to specify a source field through a model relation with dot notation. Ex.: ['category.name'] or ['customer.country.code'] where category, customer and country are model relations.
  • Added the ability to specify multiple fields with priority to look up the first non-empty source field. Ex.: In the example above, we set the look up to find a non empty source in model for slug in this order: title, first_name and last_name. Note: slug is set if at least one of these fields is not empty:
SlugOptions::create()->generateSlugsFrom([
						                'title',
						                ['first_name', 'last_name'],
							            ])
  • Added option to set the behaviour when the source fields are all empty (thrown an exception or generate a random slug).
  • Remove the abstract function getSlugOptions() and introduce the ability to set the trait with zero configuration with default options. The ability to define getSlugOptions() function in your model remained.
  • Added option to set slug separator
  • Some other adjustments and fix

##Overview

$model = new EloquentModel();
$model->name = 'activerecord is awesome';
$model->save();

echo $model->slug; // outputs "activerecord-is-awesome"

The slugs are generated with Laravels str_slug method, whereby spaces are converted to '-'.

##Requires

  • php: >=7.0.0
  • illuminate/database: ^5.0
  • illuminate/support: ^5.0

Installation

You can install the package via composer:

$ composer require padosoft/laravel-sluggable

Usage

Your Eloquent models should use the Padosoft\Sluggable\HasSlug trait and the Padosoft\Sluggable\SlugOptions class.

The trait shipping with ZERO Configuration if your model contains the slug attribute and one of the fields specified in getSlugOptionsDefault(). If the zero config not for you, you can define getSlugOptions() method in your model.

Here's an example of how to implement the trait with zero configuration:

<?php

namespace App;

use Padosoft\Sluggable\HasSlug;
use Illuminate\Database\Eloquent\Model;

class YourEloquentModel extends Model
{
    use HasSlug;   
}

Here's an example of how to implement the trait with implementation of getSlugOptions():

<?php

namespace App;

use Padosoft\Sluggable\HasSlug;
use Padosoft\Sluggable\SlugOptions;
use Illuminate\Database\Eloquent\Model;

class YourEloquentModel extends Model
{
    use HasSlug;
    
    /**
     * Get the options for generating the slug.
     */
    public function getSlugOptions() : SlugOptions
    {
        return SlugOptions::create()
            ->generateSlugsFrom('name')
            ->saveSlugsTo('slug');
    }
}

Want to use multiple field as the basis for a slug? No problem!

public function getSlugOptions() : SlugOptions
{
    return SlugOptions::create()
        ->generateSlugsFrom(['first_name', 'last_name'])
        ->saveSlugsTo('slug');
}

Want to use relation field as the basis for a slug? No problem!

public function getSlugOptions() : SlugOptions
{
    return SlugOptions::create()
        ->generateSlugsFrom('category.name')
        ->saveSlugsTo('slug');
}

where category is a relation in your model:

public function category()
{
    return $this->belongsTo('\App\Category', 'category_id');
}

It support chaining for relation so you can also pass a customer..

You can also pass a callable to generateSlugsFrom.

By default the package will generate unique slugs by appending '-' and a number, to a slug that already exists. You can disable this behaviour by calling allowDuplicateSlugs.

By default the package will generate a random 50char slug if all source fields are empty. You can disable this behaviour by calling disallowSlugIfAllSourceFieldsEmpty and set the random string char lenght by calling randomSlugsShouldBeNoLongerThan.

public function getSlugOptions() : SlugOptions
{
    return SlugOptions::create()
        ->generateSlugsFrom('name')
        ->saveSlugsTo('url')
        ->allowDuplicateSlugs()
        ->disallowSlugIfAllSourceFieldsEmpty()
        ;
}

You can also put a maximum size limit on the created slug and/or the lenght of random slug:

public function getSlugOptions() : SlugOptions
{
    return SlugOptions::create()
        ->generateSlugsFrom('name')
        ->saveSlugsTo('url')
        ->slugsShouldBeNoLongerThan(50)
        ->randomSlugsShouldBeNoLongerThan(20);
}

The slug may be slightly longer than the value specified, due to the suffix which is added to make it unique.

You can also override the generated slug just by setting it to another value then the generated slug.

$model = EloquentModel:create(['name' => 'my name']); //url is now "my-name"; 
$model->url = 'my-custom-url';
$model-save();

$model->name = 'changed name';
$model->save(); //url stays "my name"

//if you reset the slug and recall save it will regenerate the slug.
$model->url = '';
$model-save(); //url is now "changed-name";

Custom slug (i.e.: manually set slug url)

If you want a custom slug write by hand, use the saveCustomSlugsTo() method to set the custom field:

  ->saveCustomSlugsTo('url-custom')

Then, if you set the url-custom attribute in your model, the slug field will be set to same value. In any case, check for correct url and uniquity will be performed to custom slug value. Example:

$model = new class extends TestModel
{
    public function getSlugOptions(): SlugOptions
    {
        return parent::getSlugOptions()->generateSlugsFrom('name')
                                       ->saveCustomSlugsTo('url_custom');
    }
};
$model->name = 'hello dad';
$model->url_custom = 'this is a custom test';
$model->save(); //the slug is 'this-is-a-custom-test' and not , 'hello-dad';

SluggableScope Helpers

The package included some helper functions for working with models and their slugs. You can do things such as:

$post = Post::whereSlug($slugString)->get();

$post = Post::findBySlug($slugString);

$post = Post::findBySlugOrFail($slugString);
