Creating SEO-Friendly Slugs in Laravel: A Step-by-Step Guide

Creating SEO-Friendly Slugs in Laravel: A Step-by-Step Guide

In today's digital age, having SEO-friendly URLs is crucial for improving your website's visibility on search engines and enhancing user experience. In this guide, we'll show you how to generate SEO-friendly slugs in Laravel, making your URLs more readable and user-friendly.

Understanding the Importance of Slugs

A slug is a simplified version of a string that represents a resource's title or name in a URL. By optimizing your slugs, you can make your URLs more descriptive and easier for both users and search engines to understand. This can have a positive impact on your website's search engine rankings and overall user engagement.

Implementing Slug Generation in Laravel

To generate SEO-friendly slugs in Laravel, we'll use a trait-based approach. First, we'll create a trait file named GeneralHelpers in the App\Traits directory. Inside this trait, we'll define a function called generateSlug that generates a unique slug for a given model.

Here's how the generateSlug function works:

<?php

namespace App\Traits;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

trait GeneralHelpers
{
    /**
     * Generate a unique slug for a model.
     *
     * @param Model $model The model instance for which the slug is generated.
     * @param string $title The title from which the slug is derived.
     * @param string $column The column name to check for uniqueness.
     * @return string The generated unique slug.
     */
    public function generateSlug(Model $model, string $title, string $column = 'slug'): string
    {
        // Create a slug from the title using Laravel's Str::slug method
        $slug = Str::slug($title);

        // Check if the generated slug already exists in the specified column of the model's table
        $checkSlug = $model::query()->where($column, $slug)->first();

        // If the slug already exists, append a random string to make it unique
        if ($checkSlug) {
            // Append a random string to the original title to create a new slug
            $title = sprintf("%s %s", $title, Str::random(mt_rand(5, 10)));

            // Recursively call the function with the updated title to generate a new slug
            return $this->generateSlug($model, $title, $column);
        }

        // If the slug is unique, return it
        return $slug;
    }
}

Understanding the generateSlug Function

The generateSlug function is responsible for creating a unique slug for a given model. Here's a breakdown of how it works:

• Create Slug: It first generates a slug from the provided title using Laravel's Str::slug method. This method converts the title to a URL-friendly slug by replacing spaces with hyphens and removing special characters.

• Check Uniqueness: Next, the function checks if the generated slug already exists in the specified column of the model's table. If a record with the same slug exists, it means the slug is not unique, and we need to generate a new one.

• Make Slug Unique: If the generated slug is not unique, the function appends a random string to the original title and recursively calls itself with the updated title to generate a new slug. This process continues until a unique slug is generated.

• Return Slug: Once a unique slug is generated, the function returns it.

Next, we'll use this trait in our controller, such as the PostController, to generate slugs when creating new posts:

<?php

namespace App\Http\Controllers;

use App\Models\Post;
use App\Traits\GeneralHelpers;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;

class PostController extends Controller
{
    use GeneralHelpers;

    /**
     * Create a new post.
     *
     * @param Request $request The HTTP request containing the post data.
     * @return RedirectResponse The response redirecting back to the form page.
     */
    public function store(Request $request): RedirectResponse
    {
        // Validate the post data
        $data = $request->validate([
            'title' => 'required',
            'body' => 'required',
        ]);

        // Create a new Post model instance
        $post = new Post;

        // Create the post with the generated slug
        $post::query()->create([
            'title' => $data['title'],
            'slug' => $this->generateSlug($post, $data['title']),
            'body' => $data['body'],
        ]);

        // Redirect back to the form page with a success message
        return redirect()->back()->with('success', 'Post created successfully');
    }
}
