In this tutorial, we are going to create how to create slug in codeigniter.

 

A slug is a part of the URL when you are accessing a resource. Say you have a URL, such as the one below, that displays all of the posts in the system:

 

For  eg: 

http://localhost/codeigniter/view/1/how-to-upload-file-using-javascript-and-php

 

Step 1 :- Create post table in database.

 

CREATE TABLE `elevenstech`.`posts` ( `id` INT NOT NULL AUTO_INCREMENT , `title` TEXT NOT NULL , `description` LONGTEXT NOT NULL , `created_at` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP , PRIMARY KEY (`id`)) ENGINE = InnoDB;

 

Step 2 :- Create Home Controller ( Home.php ).

 

In this conttoller. We are  creating view page to load all posts.

 

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Home extends CI_Controller {
	
	public function index()
	{
        //load all post from posts table
		$lists = $this->db->select('*')->from('posts')->get()->result();

		$this->load->view('home',['lists'=>$lists]);
	}

}

?>

 

Step 3 :- Create View Page in View Folder ( home.php ).

 

In this view page. We are  loading all posts with the help of foreach loop.

 

<?php foreach ($lists as $list) { ?>

	 <div class="box_border">

	 	<h4><?php echo $list->title; ?></h4>

	 	<a href="#">View</a>

	 </div>

<?php } ?>

 

Step 4 :- Create Slug in helper Folder ( site_helper.php ).

 

In this helper file. We are  creating a slug function.

 

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

function slug($string, $spaceRepl = "-")
{
    $string = str_replace("&", "and", $string);

    $string = preg_replace("/[^a-zA-Z0-9 _-]/", "", $string);

    $string = strtolower($string);

    $string = preg_replace("/[ ]+/", " ", $string);

    $string = str_replace(" ", $spaceRepl, $string);

    return $string;
}

 

Step 5 :- Define slug file in home Controller ( Home.php ).

 

In this controlller. We are  calling slug function in contructor so that i can use this function on the view page.

 

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Home extends CI_Controller {

	public function __construct(){
		parent::__construct();

		$this->load->helper('site_helper'); // load helper file
	}

	
	public function index()
	{
		$lists = $this->db->select('*')->from('slug')->get()->result();
		$this->load->view('home',['lists'=>$lists]);
	}

}

 

Step 5 :- Create slug in anchor tag ( home.php ).

 

<?php foreach ($lists as $list) { ?>

	 <div class="box_border">

	 	<h4><?php echo $list->title; ?></h4>

        // here i am using slug
	 	<a href="<?php echo base_url().'view/'.$list->id.'/'.slug($list->title) ?>">View</a>

	 </div>

<?php } ?>

 

Step 6 :- Now use routing for view page.

 

$route['view/:num/(:any)'] = 'home/view/$1';

 

Step 7 :- Create view page for view post.

 

public function view()
{

    //here i getting id from the url
	$id = $this->uri->segment(2);

	$lists = $this->db->select('*')->from('slug')->where('id',$id)->get()->row();

	$this->load->view('view',['list'=>$lists]);

}

 

Step 8 :- Create view page to view post ( view.php ).

 

<?php 

      echo $list->title; 

      echo $list->description; 

?>

 

Result  :-
