# Custom Style / CSS > save data to database

 * Hi,
 * I am developing my own custom CSS function which I will use in my contactform,
   so users can change layout of form by adding custom css in a textarea field.
 * To add save data in database I use: sanitize_text_field
    To display save data
   in textarea field in backend I use: esc_textarea
 * My question, the sanitize_text_field removes all line breaks (does not look nice
   in textarea field backend), can I use an alternative for entering save data in
   database?
 * This I use now:
 *     ```
       register_setting( 'my_options_group', 'my_option_name', 'sanitize_text_field' );
       ```
   
 * Guido

 * There are alternatives, but they would be less secure. You could hook the ‘sanitize_text_field’
   filter, which passes the original and filtered text. You could do a diff on the
   two, replacing any line feeds found, but nothing else.
 * Or you could create your own version of `sanitize_text_field()` based on the 
   core’s source code (wp-includes/formatting.php), except your version does not
   strip line breaks. I see two places this could happen. Change the second parm
   in `wp_strip_all_tags( $filtered, true )` (line 3798) to `false`, and remove 
   the `\r\n` from `preg_replace('/[\r\n\t ]+/', ' ', $filtered)` (line 3800)

 * Hi,
 * That’s a great idea, using this default function (but remove line breaks) is 
   the best available database protection I guess.
 * Will use this. Thanks.
 * And to limit amount of content I use a simple maxlength=’1000′ on my textarea
   field.
