Custom Settings
Fieldify allows you to register custom settings panels that are shown in the block editor using only PHP and a few lines of code.
Below is an example of how to register a custom settings panel with Fieldify:
register_custom_settings('my-settings', [ 'title' => 'My Settings', 'icon' => 'dashicons-admin-generic', 'fields' => [ 'content' => [ 'type' => 'string', 'default' => 'My settings content', ], ],]);
