Dynamic default number field

The CMS Questions

String templates aka query language are not supported for most default values. What you could do is create your own number field in plugin:
PHP:

Kirby::plugin('my/plugin', [
	'siteMethods' => [
		'getSeason' => function () {
			return 5;
			},
	],
	'fields' => [
		'num' => [
			'extends' => 'number',
			'props' => [
				'default' => function ($default = null) {
					return $this->toNumber($this->model->toSafeString($default) ?? '');
				},
			]
		]
	]
]);

JS: index.js

panel.plugin("my/plugin", {
    fields: {
        num: {
            extends: "k-number-field"
        }
    }
});

Yaml:

    fields:
      season:
        type: num
        default: "{{ site.getSeason }}"

The above refers to Kirby 3 + 4, just noticed that according to the category you have chosen you still seem to be on Kirby 2, is that correct?

For Kirby 2, I can’t remember, it’s no longer supported.
