Clean and descriptive URLs are essential for SEO. Instead of numeric IDs like \/posts\/123<\/code>, you should use slugs like \/posts\/my-first-laravel-app<\/code>. In this article, we\u2019ll explore how to generate slugs automatically, prevent duplicates, allow manual editing in forms, and integrate slugs into routes and controllers.<\/p>\n\n\n\n

Auto-Generating Slugs with booted()<\/code><\/strong><\/h2>\n\n\n\n

Laravel\u2019s model events make it easy to generate slugs whenever a record is created. You can use booted()<\/code> with the creating<\/code> event.<\/p>\n\n\n

\/\/ app\/Models\/Post.php<\/span>\nnamespace<\/span> App<\/span>\\Models<\/span>;\n\nuse<\/span> Illuminate<\/span>\\Database<\/span>\\Eloquent<\/span>\\Model<\/span>;\nuse<\/span> Illuminate<\/span>\\Support<\/span>\\Str<\/span>;\n\nclass<\/span> Post<\/span> extends<\/span> Model<\/span>\n<\/span>{\n    protected<\/span> static<\/span> function<\/span> booted<\/span>()<\/span>\n    <\/span>{\n        static<\/span>::creating(function<\/span> ($post)<\/span> <\/span>{\n            $post->slug = Str::slug($post->title);\n        });\n    }\n}<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Whenever a new post is created, its title is converted to a slug. For example: \u201cMy First Laravel App\u201d \u2192 my-first-laravel-app<\/code>.<\/p>\n\n\n\n
Performance Note on booted()<\/code><\/strong><\/h3>\n\n\n\n
The booted()<\/code> method is called once per request<\/strong>, registering model event listeners. The slug logic itself only runs on the creating<\/code> event (when saving new records). Simply retrieving or initializing a model does not regenerate the slug \u2014 this keeps performance safe.<\/p>\n\n\n\n
<\/div>\n\n\n\n
Preventing Duplicate Slugs<\/strong><\/h2>\n\n\n\n
Duplicate slugs cause routing conflicts and SEO issues. For example, two posts titled \u201cHello World\u201d would both generate hello-world<\/code>. A better approach is to check existing slugs and append a number if needed.<\/p>\n\n\n
\/\/ app\/Models\/Post.php<\/span>\nprotected<\/span> static<\/span> function<\/span> booted<\/span>()<\/span>\n<\/span>{\n    static<\/span>::creating(function<\/span> ($post)<\/span> <\/span>{\n        $base = Str::slug($post->title);\n\n        \/\/ If slug is free, use it directly<\/span>\n        if<\/span> (! static<\/span>::where('slug'<\/span>, $base)->exists()) {\n            $post->slug = $base;\n            return<\/span>;\n        }\n\n        \/\/ Otherwise compute next suffix<\/span>\n        $pattern = '^'<\/span> . preg_quote($base, '\/'<\/span>) . '(-[0-9]+)?$'<\/span>;\n\n        $maxSuffix = static<\/span>::whereRaw('slug REGEXP ?'<\/span>, [$pattern])\n            ->selectRaw(\"\n                MAX(\n                    CASE\n                        WHEN slug = ? THEN 0\n                        ELSE CAST(SUBSTRING_INDEX(slug, '-', -1) AS UNSIGNED)\n                    END\n                ) AS max_suffix\n            \"<\/span>, [$base])\n            ->value('max_suffix'<\/span>);\n\n        $post->slug = $base . '-'<\/span> . (((int) $maxSuffix) + 1<\/span>);\n    });\n}<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
With this strategy, your slugs remain unique:<\/p>\n\n\n\n
