This guide will describe how to update Papi 2 to Papi 3.
Meta method in page type classes
In Papi 3 we remove page_type and option_type, this is because we think that one name is better than multiple. With string replace you can replace all your page_type and option_type with meta and you’re page types should work with Papi 3.
Remove method in page type classes
The are some changes to how the page type class should be created. $this->remove has been removed and could not be used in register method anymore. This is because we removed one of the calls to register method so the boxes isn’t loaded twice.
The old way:
public function register() {
$this->remove( ['editor'] );
}
The new way:
public function remove() {
return ['editor'];
}
public function register() {
}
You will need to implement a method call remove that returns a string or array of strings that will be used to remove post type supports or meta boxes.
Properties
Flexible
Flexible property will only save one layout per row. The layout key is changed from _layout to _flexible_layout since _layout can be a real slug.
It has backward compatibility for the old layout key. This may cause problem with existing slugs that are named layout. To fix default value issue you need to manually add the layout value for the effected row.
The slug will be something like this: sections_0_flexible_layout, where sections is your flexible slug, 0 is the row and _flexible_layout is the new layout key. The value should be a slug of the layout title, the same value as the old _layout rows that exists on each property.
Flexible and Repeater
If you did array properties without call papi_property for flexible or repeater items you need to use papi_property since we removed the support for array properties. So just use papi_property( [] ) and not [].
Text
Since 3.0.0 nl2br is added as setting to text property and true by default #135.
