Usage Feed

You can use this in a template for a dedicated feed page, in a template controller or a route.

<?php
$options = [
    'title'       => 'Latest articles',
    'description' => 'Read the latest news about our company',
    'link'        => 'blog'
];
echo page('blog')->children()->listed()->flip()->limit(10)->feed($options);

options array defaults

If you use these defaults you need to provide the fields date (type: date) and text (type: text).

[
    'url' => site()->url(),
    'feedurl' => site()->url() . '/feed/',
    'title' => 'Feed',
    'description' => '',
    'link' => site()->url(),
    'urlfield' => 'url',
    'titlefield' => 'title',
    'datefield' => 'date',
    'textfield' => 'text',
    'modified' => time(),
    'snippet' => 'feed/rss', // 'feed/json', 'feed/atom'
    'dateformat' => 'r',
    'mime' => null,
    'sort' => true,
]

virtual page in site/config/config.php

return [
    'routes' => [
        [
            'pattern' => 'feed',
            'method' => 'GET',
            'action'  => function () {
                $options = [
                    'title'       => 'Latest articles',
                    'description' => 'Read the latest news about our company',
                    'link'        => 'blog'
                ];
                $feed = page('blog')->children()->listed()->flip()->limit(10)->feed($options);
                return $feed;
            }
        ],
    ],
];

HTML head element

rss xml

<link rel="alternate" type="application/rss+xml" title="Latest articles" href="<?= site()->url() ?>/feed"/>

and/or rss json

<link rel="alternate" type="application/json" title="Latest articles" href="<?= site()->url() ?>/feed"/>

TIP: Having multiple feed links is still valid html. So you can have both rss and json if you want and setup the routes properly.

Sorting

The Plugin applies a default sorting for the pages by date/modified in descending order (newest first).

  • If you do not want this you have to set the datefield setting to another Field name or PageMethod name.
  • If you want to disable sorting by the plugin and add your own you can set the option sort to false.

Pitfalls when presorting by date and limit

Using sortBy('date', 'desc') will not yield expected results! In K3 sorting by date needs a callback.

$feed = page('blog')->children()->listed()->sortBy(function ($page) {
 return $page->date()->toDate();
}, 'desc')->limit(10)->feed($options);

Usage Sitemap

options array defaults

If you use these defaults you need to provide the fields date (type: date) and text (type: text).

[
    'dateformat' => 'c',
    'xsl' => true,
    'urlfield' => 'url',
    'modified' => time(),
    'snippet' => 'feed/sitemap',
    'mime' => null,
    'sort' => true,
    'images' => false,
    'imagesfield' => 'images',
    'imagetitlefield' => 'title',
    'imagecaptionfield' => 'caption',
    'imagelicensefield' => 'license',
    'videos' => false,
    'videosfield' => 'videos',
    'videotitlefield' => 'title',
    'videothumbnailfield' => 'thumbnail',
    'videodescriptionfield' => 'description',
    'videourlfield' => 'url',
]

virtual page in site/config.php

return [
    'routes' => [
        // ... other routes,
        [
            'pattern' => 'sitemap.xml',
            'method' => 'GET',
            'action'  => function () {
                $options = [
                    'images'       => false,
                    'videos'       => false,
                ];
                $feed = site()->index()->listed()->limit(50000)->sitemap($options);
                return $feed;
            }
        ],
        // (optional) Add stylesheet for human readable version of the xml file.
        // With that stylesheet visiting the xml in a browser will per-generate the images.
        // The images will NOT be pre-generated if the xml file is downloaded (by google).
        [
            'pattern' => 'sitemap.xsl',
            'method' => 'GET',
            'action'  => function () {
                snippet('feed/sitemapxsl');
                die;
            }
        ],
    ],
];
