update from best practice

Hi,

I'm codeigniter newbie. I'm trying to create update form. It works like this (standard): then user visits page it shows values from database, then user submits form it should show values entered by user + error message. As far as i understand from tutorial i should use form helper for this, and write something like this in my view:

Code:

<input type="text" name="name" value="<?php echo set_value('name', isset($data['name'])?$data['name']:'') ?>">

$data['name'] - is value read from db. I need to use construction

Code:

isset($data['name'])?$data['name']:''

because if form is rendered after user submit, then we don't read data from database and variable $data is not defined. On my mind it is annoying to write something like this each time.
So my question is: is there better solution for views that contain update/edit forms? I'm sure there should be nice solution, but unfortunately all tutorials and examples i've found were about add/create forms. What good/standard practice for this?
