Answer 1

the problem here is that you don't supply the correct array to your model Uploadmodel, which is waiting for an array, while you are sending 4 different strings.
the correct approach is to send the array, which you could do like this:
if($this->Uploadmodel->websiteinsert($post)){
// etc.
}
or if you your $post has more elements than you want to insert you could also:
if($this->Uploadmodel->websiteinsert(array($post['firstname'],$post['lastname'], $post['email'],$post['whatsapp'],$post['buissness']))){
//etc.
}
or use unset($post['foo']) to get rid of $post() elements you don't want to insert
