Estou escrevendo um plugin para enviar um convite a um amigo que abre um formulário quando um link é clicado. Encapsulei todas as funções da classe seguindo o código fornecido no plug-in Report Broken Video de @toscho. O código relevante está abaixo:
/*

Não sei como usar essa classe no meu modelo para que eu possa exibir o formulário. Eu sei que preciso instanciar a classe, mas não sei onde colocar o código e como acessar o objeto para que eu possa usá-lo no meu modelo. Eu tenho conhecimento de POO, mas não o usei neste contexto antes e preciso de um pouco de instruções passo a passo.
Muito Obrigado.
