default value in edit view

[eluser]huzzi[/eluser]
I can't get this to work.. can't set the default value from within controller. I know how to get this working with the older version of CI. What am i doing wrong? please help.

view:

Code:

<input name="a" type="text" value="<?php echo set_value('a');?>" />

Controller:

Code:

function update(){
       $this->load->library('form_validation');
       $this->form_validation->set_rules('a', 'a', 'required');
       $this->form_validation->set_value('a','qwerty');

         if ($this->form_validation->run() == FALSE)
        {
          $this->render('member','member/update_profile');
        }
        else
        {
           // code to update
        }
}

Any help would be appriciated.

Many thanks.

Hmm, there doesn't appear to be anything in the user guide on

Code:

$this->form_validation->set_value();

Do you NEED to set it in the controller, cause you can set the default value in the view as a second paramter

Thanks Dam1an,

How do you populate form data from database?

I've not actually done any edit forms using the new validation library lol
but an easy work around would be to pass the variables into the view and then use set_value('a', $a);

What does

Code:

value="<?php echo set_value('a');?>"

actually output in your html? Unless set_value is returning a value, that shouldn't be setting the value.

To update values of fields from a database,.. you would need javascript to do it without a page refresh. If you submitting the form back to itself, php will work

Sorry if this makes no sense. Its early, and i had a long night
