POO, PHP MVC Helper "MainHelper"
Antes de utilizar cualquier helper debes saber:
- Las clases están pensadas para su utilización en la arquitectura en tres capas. Pero la puedes adaptar para incluirla en cualquier proyecto
- El código html que se generá se basa en un proyecto con HTML5 y jquery mobile
- No es la última versión puesto que día a dia voy mejorando el código o añadiendo mas funcionalidad
- Todos los helpers contarán con el metodo get_html(), el cual devuelve un sring.
- Todos los helpers contarán con el metodo show(), este hace un "echo" del metodo anterior
