How to use

Add these options to path/to/cockpit/config/config.php to specify the collections and field names for slug generation:

<?php

return [
    'app.name' => 'my app',

    // unique slugs
    'unique_slugs' => [
        'collections'    => [
            'pages'      => 'title',
            'products'   => 'name',
        ],
        'localize' => [
            'pages'     => 'title',
            'products'  => 'name',
        ],
    ],

    // ACL example
    'groups' => [
        'manager' => [
            'cockpit' => [
                'backend' => true,
            ],
            'uniqueslugs' => [
                'manage' => true,
            ],
        ],
    ],
];

all options:

<?php

return [
    'app.name' => 'my app',

    // unique slugs
    'unique_slugs' => [
        'slug_name'      => 'slug', // default: "slug"
        'placeholder'    => 'page', // default: "entry"
        'check_on_update' => true,  // default: false, unique checks on each
                                    // update (if user changes slug by hand)
        'delimiter'      => '|',    // default: "|", is used for nested fields

        'collections'    => [
            'pages'      => 'title',
            'products'   => 'name',
            'something'  => [       // use multiple fields as fallbacks
                'title',
                'name',
                'image|meta|title', // use nested fields for slugs
            ],
        ],
        'localize' => [             // for localized fields, omitted if not set
            'pages'     => 'title', // field name without suffix ("_de")
            'products'  => 'name',
            'something' => [        // use multiple fields as fallbacks
                'title',
                'name',
                'image|meta|title', // use nested fields for slugs
            ],
        ],
    ],

    // ACL example
    'groups' => [
        'manager' => [
            'cockpit' => [
                'backend' => true,
            ],
            'uniqueslugs' => [
                'manage' => true,
            ],
        ],
    ],
];

Or use the GUI. If you are no admin, your user group needs manage rights.

Notes:

Hardcoded settings in the config file will override gui settings.

Don't set slug_name: fieldname_slug if you also set {"slug": true} in the fieldname options for some reason. It should work, but it fails on multilingual setups (explanation).

Your collection can have a visible field named "slug", if you want to edit it by hand.

The builtin option to sluggify text fields via options {"slug": true} in the backend uses Javascript. If you want unique slugs, that option is not necessary anymore.

The code for this addon is inspired by a gist from fabianmu.
