I am just starting with cakephp2.8. Is there any resource that explains how to integrate/use this? All I did was drop your file with .php ext and a folder with the same name in app/plugin as app/plugin/bootstrapformhelper/bootstrapformhelper.php and I am getting error saying there is not view for this. I don't know why it needs a view though
