Modificar funcion enviar Mail

Hola  buen dia!
te consulto lo siguiente
cuando un Cliente publica un proyecto y coincidan -solo- los Skills, se envia un mail diciendole que tiene un nuevo proyecto ....

Ahora bien, yo necesito agregar que cuando coincida no solamente skill sino tambien la categoria, y

Es decir necesito que cuando reuna esas dos coincidencias de manera conjunta, se envie el mail



El archivo que maneja la funcion de enviar mail es el siguiente:

(se puede ver que tiene una actualizacion y antes enviaba mail cuando coincidia la categoria, yo necesito que se den las dos juntas)
