Passing array in add_option()

I think that you have added bguru_options option before. If bguru_options already exists, add_option() does nothing. To modify the value of existing options you should use update_option() instead.

EDIT

I confirm what I thought. You are running add_option('bguru_options', $default_options); in every admin_init. bguru_options option was added to database in the first run and subsequent calls to add_option('bguru_options', $default_options); are doing nothing.

• Use update_option() to change the value of a existent option. If the option doesn’t exist, it will be created.
• Use add_option() if you really need it. For example, if you need to set autoload=no. This parameter is not accepted by update_option(). Do this preferably during plugin/theme activation
• If you need to use add_option() and you are not sure if the option already exists, use delete_option() before call add_option().

EDIT 2

I’ve tested your code exactly as it is and I’ve tested it. The default logo URL is correctly added to database in the bguru_options option and returned by get_option('bguru_options');:

$options=get_option('bguru_options');
var_dump($options['bguru_logo']);

There is no problem at all. The only drawback is that if the you leave the URL field empty, the default logo URL is not set because, I repeat, add_option() is doing nothing in subsequent calls because bguru_options option already exists.

I’ve tested the code and it works. If it does not work for you I will need more information. Maybe some debug log?

Anyway, I wnat to show you how get_option() support default values without the need of store default values in the database:

$default_options=array(
     'bguru_logo'=>'http://templategraphy.com/demo/businessguru/images/logo.png',
     'bguru_vimeo'=>'',
     'bguru_skype'=>'',
     'bguru_dribbble'=>'',
     'bguru_slide_one_image'=>'',
     'bguru_slide_one_heading'=>'',
     'bguru_slide_one_text'=>''
 );
 $bguru_options = get_option('bguru_options', $bguru_options_defaults);
 //Set defaults for unsaved subset in the array
 $bguru_options = wp_parse_args( $bguru_options, $bguru_options_defaults );
