````
$inputText = Input::only(
    'company_name', 
    'company_url', 
    'eligibility_text', 
    'footer_text', 
    'basic_info_help_text', 
    'create_account_help_text', 
    'profile_create_help_text', 
    'application_create_help_text', 
    'recommendation_create_help_text', 
    'recommendation_update_help_text', 
    'application_submit_help_text', 
    'nominate_text', 
    'tracking_code_id', 
    'status_page_help_text_incomplete', 
    'status_page_help_text_submitted',
