Sitemap generation with Codeigniter

Question

I need to generate a sitemap in a Codeigniter application. I found a few libraries but all of them are outdated and have bug.

Do I really need a separate library for this?

I want to know the best way to generate the sitemap in Codeigniter.

Answer 1

You can use my code:

controllers/seo.php

Class Seo extends CI_Controller {

    function sitemap()
    {

        $data = "";//select urls from DB to Array
        header("Content-Type: text/xml;charset=iso-8859-1");
        $this->load->view("sitemap",$data);
    }
}

views/sitemap.php

<?= '<?xml version="1.0" encoding="UTF-8" ?>' ?>

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
    <url>
        <loc><?= base_url();?></loc> 
        <priority>1.0</priority>
    </url>

    <!-- My code is looking quite different, but the principle is similar -->
    <?php foreach($data as $url) { ?>
    <url>
        <loc><?= base_url().$url ?></loc>
        <priority>0.5</priority>
    </url>
    <?php } ?>

</urlset>

add line to config/routes.php

$route['seo/sitemap\.xml'] = "seo/sitemap";

Sorry if there are some errors in the code, I made it especially for you. If there are errors, you can fix them easily by understanding the principle.

Must set header :

<?php header('Content-type: text/xml'); ?>
<?= '<?xml version="1.0" encoding="UTF-8" ?>' ?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
    <url>
        <loc><?= base_url();?></loc> 
        <priority>1.0</priority>
    </url>
    <!-- My code is looking quite different, but the principle is similar -->
    <?php foreach($data as $url) { ?>
    <url>
        <loc><?= base_url().$url ?></loc>
        <priority>0.5</priority>
    </url>
    <?php } ?>
</urlset>

It's strongly recommended to add the link of the sitemap to the robots.txt like this:

Sitemap: http://www.yoursite.com/seo/sitemap

Answer 4

I've written a CodeIgniter model which enabled you to call functions from a sitemap controller and spit out the XML when you're all done feeding the sitemap.

Feel free to have a look and reuse the CodeIgniter model:
