Return back values to view if any error in form fields

Yes works fine.

Controller:

PHP Code:

// set data for test input field
$page_data['input_data'] = array(
   'value' => set_value('test_input', ''),
   'class' => 'input_field',
   'name' => 'test_input',
);
// set some rule to trigger an error and repopulate the field
$this->form_validation->set_rules('test_input', 'Test Input', 'max_length[3]');
$this->form_validation->run(); 


View:

PHP Code:

<?php echo form_open(); ?>
   <?php echo form_input($input_data); ?>
   <?php echo form_error('test_input'); ?>
   <?php echo form_submit(array('value'=>'save')); ?>
<?php echo form_close(); ?>

Just make sure you have both the form helper loaded and the form_validation library loaded.

Best wishes,
