Validating groups of inputs

[eluser]Ihab Khattab[/eluser]
what I understand you have problem in setting rules for select

for example if your markup for select something like

Code:

<select name="coor-sys">

<option value="dec">Decimal latitude / longitude</option>
<option value="grid">Grid reference</option>
<option value="Lat/long">Latitude / longitude</option>

</select>

you should write something like

Code:

$config = array(
               array(
                     'field'   => 'locationName',
                     'label'   => 'Location name',
                     'rules'   => 'required'
                  ),
               array(
                     'field'   => 'locationDescription',
                     'label'   => 'Location description',
                     'rules'   => 'required'
                  ),
               array(
                   'field'   => 'coor-sys',
                   'label'   => 'Coordination system',
                   'rules'   => 'required'
               )
            );
$this->form_validation->set_rules($config);

I modified the code you provide as I think it won't work. for more example about passing rules as an array you may check
