Hi,

I’m trying to install bnomei’s kirby3-feed but am suddenly encountering this issue. I’m on:

Kirby 4
ZOON
Testing on local

Steps:

I unzipped the folder into site/plugins and renamed kirby3-feed
I added the following to site/config/config.php:

[
            'pattern' => 'feed',
            'method' => 'GET',
            'action'  => function () {
                $options = [
                        '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,
                ];
                $feed = page('blog')->children()->listed()->flip()->limit(10)->feed($options);
                return $feed;
            }
        ],

I added <link rel="alternate" type="application/rss+xml" title="Latest articles" href="<?= site()->url() ?>/feed"/> between <head> and </head> in site/snippets/head.php

When I go to http://localhost:8080/feed, I get:

<rss version="2.0">

etc.
</channel>
</rss>

With the message This XML file does not appear to have any style information associated with it. The document tree is shown below. on top.

And when I try to subscribe to it in my reader, it doesn’t update with anything.

The weird thing is I got it to work the other day (on an earlier iteration of my site) and I could have sworn I did the same thing then and it updated in my reader.

I appreciate any advice, thanks!

Edit: In case relevant, I have the following plugins installed:

icon
icons
kirby-cookie-banner
kirby3-feed
kirby3-redirects
resize
retour
tooltip

can you try validating the rss xml output with this and report back? thanks.

So I copied and pasted the following into the Validate by direct input option in that link:

that should not happen as the title is set with Kirby\Toolkit\Xml::encode() for encoding and & should be &. i will have a closer look asap.

I don’t know if this extra information will help but what I did was I started a fresh folder of Kirby 4 + ZOON + kirby3-feed, and repeated the same steps I did above to install.

When I check http://localhost:8080/feed, I still get the message This XML file does not appear to have any style information associated with it. The document tree is shown below. and this is what is shown on-screen:

And when I try to add it to my reader, the feed doesn’t update. These are the default posts that come with ZOON.

However, when I run it through the direct input validator, it says:

Congratulations!

Recommendations

This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.

I tested with a local setup, and both channel and item title properly escaped when pulled from Kirby. & in any content TXT files becomes & in the outputted XML string. I do not know the reason why that would fail for your setup.

You could directly add code to the site/plugins/kirby3-feed/snippets/rss.php trying to debug this further.

silverhuang · November 29, 2024, 3:11am

I finally got around to downloading a fresh copy of everything, including ZOON and the latest version of your plugin today, and repeated everything and now it works. Maybe you updated something that fixed whatever problem I was running into; if so thank you!
