I'm always using Form Class, Input Class and Form Validation for new code. And for legacy I'm using Form Class and Input Class/$_POST. But my goal are to port everything to Form Validation.

For static pages like "Creating documents", where users can't add/delete e.g. <input> I'm writing it like form_input();
PHP Code:
<div class="form-group">
    <?php echo form_label(lang('documents_description'),'documents_description'); ?>
    <p class="help-block"><?php echo lang('documents_description_help'); ?></p>
    <?php
        echo form_textarea(array(
                'name'    => 'documents_description',
                'value'    => set_value('documents_description'),
                'class' => 'form-control',
                'rows'  => '3',
            ));
    ?>
</div> 

For forms that users can manipulate I have created a form_generator helper, so that I can reuse it.
PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

if ( ! function_exists('forms_generator'))
{
    /**
     * Form Generator Helper

            return $count;
        
        foreach($array as $a)
        {
            $count += strlen($a->$name);
        }
        return $count;
    }
} 

And how you use it.
PHP Code:
$odd_even = 'odd';
if( !empty($questions) && isset($page_current) ):
    if( !empty($page_current->description) )
        echo '<div class="form-group-description">' . nl2br(html_escape($page_current->description)) . '</div>';
    if( isset($questions[0]) ):
        foreach($questions[0] as $question):
            $odd_even = $odd_even === 'even' ? 'odd' : 'even';
            $o = isset($options[$question->question_id]) ? $options[$question->question_id] : array();
            $s = isset($selected[$question->question_id]) ? $selected[$question->question_id] : '';
            $q = $question;
            if( in_array($question->field, array('table')) )
            {
                $o = $options;
                $s = $selected;
                $q = $questions;
                $odd_even = 'even';
            }
            forms_generator($question->field, $question->question_id, $question->name, $question->description, $o, $s, $question->settings, $odd_even, TRUE, $q);
            if( isset($questions[$question->question_id]) && !in_array($question->field, array('table')) ):
                foreach($questions[$question->question_id] as $sub):
                    $o_sub = isset($options[$sub->question_id]) ? $options[$sub->question_id] : array();
                    $s_sub = isset($selected[$sub->question_id]) ? $selected[$sub->question_id] : '';
                    forms_generator($sub->field, $sub->question_id, $sub->name, $sub->description, $o_sub, $s_sub, $sub->settings, $odd_even);
                endforeach;
            endif;
        endforeach;
    endif;
else:
    echo $form->description;
endif;
