Help in Form Helpers using Validation Class

#1
[eluser]Civic[/eluser]
Hi, I am a newbie in CodeIgniter. Can I place a validation in a form_input? Because in the examples in the forums, the view uses html tags while I used echo form_input($field_id).

Where model index is;
$data['field_id'] = array('field_id'=>'field_id','maxlength'=>8,'size'=>8);

Where controller index is;
$this->load->view('module1/add',$data);

Where add view is;
<?php
$attributes = array('name' => 'addView', 'id' => 'addView');
echo form_open('modules/add',$attributes);
?>
<?php echo form_input($field_id);?>

<?php echo form_close();?>

How do I add?
$rules['field_id'] = "required";
$this->validation->set_rules($rules);

Thanks in advance..

The common use is that you do the validation in your controller. it doesn't matter if you use static html or let the html generate for you, form_input, the result should be the same.

Thanks xwero for the reply. I did what you said. But I need more help. It seems I cant display my error message. below is the snippets of my code. Can you check what am I doing wrong? Thanks.

Where model index is;

$data['field_id'] = array('name'=>'field_id',
'maxlength'=>8,
'size'=>8,
'value'=>(isset($this->validation->field_id) ? $this->validation->field_id : '')
);
Where controller add is;
$rules['field_id'] = "required";
$this->validation->set_rules($rules);
if($this->input->post('save')){
if ($this->validation->run() == FALSE) {
$this->load->view('modules/addView',$data);
} else {
$this->modules_model->add();
$data['query'] = $this->modules_model->getall();
$this->load->view('modules/index',$data);
}
} else {
$this->load->view('modules/addView',$data);
}
Where add view is;

<?php
$attributes = array('name' => 'addView', 'id' => 'addView');
echo form_open('modules/add',$attributes);
?>
<?php echo form_input($field_id);?>
<?php echo $this->validation->field_id_error; ?>
<?php echo form_submit('save','Save');?>
<?php echo form_close();?>
