Form validation - remembering values for <select>

[eluser]Dauntless[/eluser]
Hi,

I'm using the form validation class and I have a select field in my form:

Code:

<select name="team[]" multiple="multiple" size="3">
            <option value='-1' &lt;?= $this->validation->set_select('team', '-1')?&gt;>None</option>
            &lt;?
            foreach ( $teams as $key=>$val ){
                   print "<option value='$key' " . $this->validation->set_select('team', "$key").">$val</option>\n";
            }            ?&gt;
            </select>

The problem is that the values aren't remembered. I tried using 'team[]', but that doesn't work either ...

I am however able to load the data in the controller and process it:

Code:

$rules['team'] = "callback_team_check";

// ...
function team_check($arg)
    {
        if($arg[0] == -1 && count($arg) > 1)
        {
            $this->validation->set_message('team_check', '...');
            return false;
        }
        
        if(count($arg) == 0)
        {
            $this->validation->set_message('team_check', '...');
            return false;
        }
        
        return true;
    }

How can I get the validation class to remember my selected values ?

All help is appreciated!

After a review of the validation library you can't use set_select with multiple-values select... :-(
The set_select test is :

Code:

if ($_POST[$field] == $value)

So if you pass 'team' (as in your example) as the field argument it will test $_POST['team'] , which is an array. If you pass 'team[]' it will test $_POST['team[]'] , which is not defined.

Hi Dauntless,

There is a new validation library being worked on in the SVN: 'form validation'.

It supports multi-dimensional arrays as well as re-selecting it.

This will be part of the 1.7 release, however you can pull it out of the svn as well for the time being. (do a full checkout, as several helpers are changed as well to support this new form validation library)

Thanks for your replies, Dready & Drewbee .

I'll check out the SVN and see what's easier: Writing my own little hack or updating the helper libraries.

At least now I know it's not something I'm doing wrong...

I agree. The new library has some very nice features to go along with it. I personally am glad I just started using CI, now I don't have to go through and revert a ton of code! There is a thread entitled "Who wants to test the new validation class", or similiar. It has all of us picking and suggesting fixes as well as things that could be improved upon.
