form_validation: Re-populating field without rules

Boy - that is hackish, but certainly a general solution. I'm torn between amending the form_validation class, putting this in my controllers, or simply adding rules to my config (even though I hate that)...

Agree with this. Although the whole point of the form_validation class and helpers is NOT to have to do that.

I really like this solution. I wonder if this is more CI friendly, though:

function field_value($field,$default='') {
$CI =& get_instance();
$value = $CI->input->get_post($field, true);
return false === $value || '' === $value ? $default : $value;
}


This way you tie into CI's native Input class.

you could use post instead of get_post if you were not concerned with GET[];
