When i submit my options, in the Theme Options page of my custom theme, it saves also empty text fields.

E.G.:

sample_theme_options => array(
   text_field_1 = '',
   text_field_2 = 'blah blah'
 )

How can I filter text fields, deleting empty ones?

use the native array_filter( $array ); to get rid of empty/false/null values. – kaiser Sep 25 '12 at 1:18
