Is there a hook attached to general settings save?

1. You just need to register_setting() on your setting and it will be saved automatically. See the Settings API for more info. Here’s a complete example:

   function spw_cb() {
       if( !($value = get_option('sprockets_per_widget')) ) {
           $value = 7;
       }
   
       ?>
       <input type="text" size="3" name="sprockets_per_widget" value="<?php echo $value; ?>" /> Numeric only!
       <?php
   }
   
   function spw_init() {
       add_settings_field('sprockets_per_widget', 'Sprockets per Widget', 'spw_cb', 'general');
       register_setting('general', 'sprockets_per_widget', 'intval');
   }
   add_action('admin_init', 'spw_init');
