MasterPress 1.3.1 is a compatibility release for PHP 8 and WordPress 5.7. It still remains backwards compatible with older PHP versions.
MPFT :: __toString()
Note: many field types will overload this method to allow different types to output more appropriate HTML code. For example, the image type will output an image tag (which is more useful than the URL which is stored), and the Visual Editor type will run the WordPress content filters over the content of the field.
This method is not intended to be called directly.
