Generate slugs when saving Eloquent models

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

The slugs are generated with Laravels Str::slug method, whereby spaces are converted to '-'.

Installation

You can install the package via composer:

Usage

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

The trait contains an abstract method getSlugOptions() that you must implement yourself.

Your models' migrations should have a field to save the generated slug to.

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

With its migration:

Using slugs in routes

To use the generated slug in routes, remember to use Laravel's implicit route model binding:

Using multiple fields to create the slug

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

Customizing slug generation

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.

Limiting the length of a slug

You can also put a maximum size limit on the created slug:

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

You can also use a custom separator by calling usingSeparator

Setting the slug language

To set the language used by Str::slug you may call usingLanguage

Overriding slugs

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

Prevents slugs from being generated on some conditions

If you don't want to create the slug when the model has a state, you can use the skipGenerateWhen function.

Prevent slugs from being generated on creation

If you don't want to create the slug when the model is initially created you can set use the doNotGenerateSlugsOnCreate() function.

Prevent slug updates

Similarly, if you want to prevent the slug from being updated on model updates, call doNotGenerateSlugsOnUpdate().

This can be helpful for creating permalinks that don't change until you explicitly want it to.

Regenerating slugs

If you want to explicitly update the slug on the model you can call generateSlug() on your model at any time to make the slug according to your other options. Don't forget to save() the model to persist the update to your database.

Preventing overwrites

You can prevent slugs from being overwritten.

Using scopes

If you have a global scope that should be taken into account, you can define this as well with extraScope. For example if you have a pages table containing pages of multiple websites and every website has it's own unique slugs.

Setting the slug suffix starting index

By default, suffix index starts from 1, you can set starting number.

Integration with laravel-translatable

You can use this package along with laravel-translatable to generate a slug for each locale. Instead of using the HasSlug trait, you must use the HasTranslatableSlug trait, and add the name of the slug field to the $translatable array. For slugs that are generated from a single field or multiple fields, you don't have to change anything else.

For slugs that are generated from a callable, you need to instantiate the SlugOptions with the createWithLocales method. The callable now takes two arguments instead of one. Both the $model and the $locale are available to generate a slug from.

Implicit route model binding

You can also use Laravels implicit route model binding inside your controller to automatically resolve the model. To use this feature, make sure that the slug column matches the routeNameKey.
Currently, only some database types support JSON operations. Further information about which databases support JSON can be found in the Laravel docs.

Find models by slug

For convenience, you can use the alias findBySlug to retrieve a model. The query will compare against the field passed to saveSlugsTo when defining the SlugOptions.

findBySlug also accepts a second parameter $columns just like the default Eloquent find method.
