README

Have you ever wanted an easy way to set up pretty URLs with CodeIgniter? This library is made for you!

SteeveDroz\CiSlug\Slugify allows you to calculate what URL-compatible name fits with a given title or name.

Install

To install this library, type composer require steevedroz/ci4-slug from your CodeIgniter project.

Usage

Basic usage

Slugify is intended to be used from a Model as it requires one. Here is an example of the default usage:

<?php

namespace App\Models;

use CodeIgniter\Model;
use SteeveDroz\CiSlug\Slugify;

class PageModel extends Model
{
    protected $table = 'pages';
    protected $allowedFields = ['title', 'content'];

    protected $beforeInsert = ['setSlug'];

    public function setSlug($data)
    {
        $slugify = new Slugify($this);
        $data = $slugify->addSlug($data, 'title');
        return $data;
    }
}

This code will look for the title value of the incomming data and calculate the corresponding slug. If a database entry already has that given slug, it will increment the slug with a -N suffix. For instance: hello-world becomes hello-world-2, which becomes hello-world-3, and so on until a free slug is found.

Configuration

If you use a slug field that is not called slug, you can call $slugify->setField('your_slug_field_name') to change the default behaviour.

If you need to strip the diacritics (for instance, the title Best Crème Brûlée recipe should have the slug best-creme-brulee-recipe), add a second parameter to the constructor and set it to true.
