Custom plugin: "The JSON response from the API could not be parsed"

The CMS Questions

Using Kirby 3.3.0-rc.2 in the same development system I followed Kirby-Docs: How to create your own KirbyTag and added /site/plugins/your-plugin/index.php with the published content:

Kirby::plugin('your/plugin', [
    'tags' => [
        'wikipedia' => [
            'html' => function($tag) {
                return '<a href="http://wikipedia.org">Wikipedia</a>';
            }
        ]
    ]
]);

When I now press the key F5 (Reload the panel), I get:

The JSON response from the API could not be parsed. 
Please check your API connection.

[Added:]
I checked it with a new installed Starterkit 3.2.5 and Kirby 3.3.0-rc.2. It is the same.
I changed nothing in the content files!

Does the file start with an opening PHP tag like so:

<?php

Kirby::plugin('your/plugin', [
    'tags' => [
        'wikipedia' => [
            'html' => function($tag) {
                return '<a href="http://wikipedia.org">Wikipedia</a>';
            }
        ]
    ]
]);

No, you added this line after my test, thank you very much!

I hope, this will solve my problem.
But I can check this not till tomorrow and will tell you what I get.

PHP files always need to start with an opening tag, otherwise the code is output 1:1 to the browser without being executed.

I’ve added it to the docs to make the examples clearer.

There are many code parts in the docs, which don’t have that first line…

I have a problem with a custom code in another tags file, which I have to update from Kirby 2 to 3. I wanted to check “quick and dirty”, whether this is affected by the new Kirby version.
Normally I know about this line…
Tomorrow I will pay more attention…

Thank you very much. For the code from the docs it helped.

But my real problem was, that my tags code

... // some code

      'html' => function($tag) {

        $subpages = $tag->parent()->children();
        if($children == 'visible') {
          $subpages = $subpages->visible();
        } elseif($children == 'invisible') {
          $subpages = $subpages->invisible();
        }

... // some code

had some deprecated code, which I did not get reported although debug was enabled.

But that is another storry.
And I have this code now updatet too :sweat_smile:
