Validation -> Model

[eluser]Colin Williams[/eluser]
I personally don't like the model accessing $_POST data because that, in a way, couples the model too tightly with the view (what if the data is retrieved by means other than a posted form, like CSV imports, etc). Typically all of my insert-type model functions accept an object to save (or array) which it filters through to remove unneeded properties before doing the SQL. Then a controller can just pass it $_POST, as in the examples above.

Code:

function update()
{
   if ($this->blog_model->save($_POST)
   {
      // Update worked
   }
}
