Using the [code][/code] shortcode only outputs what is inside as PRE and CODE elements of HTML, useful for showing code to your readers. In general, it is a bad idea to put code directly into … Read more
You can only do this by “loading content into all the posts in the blog” asynchronously (in the background). So, move the processing inside a function that you hook on wp_ajax_your_action_tag. Then call this function with javascript by requesting WP to fire “your_action_tag”. There’s a example on the linked page… If you want to display … Read more
You only need one register_setting() call. The rest can be handled internally. I wrote a Settings API tutorial that explains how to do so. Without delving too deeply into the code from the tutorial you linked, just based on the screenshot it appears that the Digital Raindrops code bypasses the standard, WordPress core admin UI … Read more

Not tested, but I think your problem is trying to update elements of the array instead of the whole thing: $the_options = get_blog_option($blog_id, … Read more
First add a validation callback to your register_settings: register_setting( ‘settingsapi_optiongroupname’, ‘settingsapi_optionname’,’validation_callback’); then define validation_callback: function validation_callback($input){ //check if all is good //If so then return the wanted value to be saved //If Not then hook your admin notice function and return null to be saved ex: if ($something){ return $input; }else{ add_settings_error(‘unique_identifyer’,esc_attr(‘settings_updated’),__(‘Settings saved.’),’updated’); add_action(‘admin_notices’, ‘print_errors’); … Read more
Add a new settings section for the reset button that is called on every tab. In the callback function for the field create the reset button. I would include the submit button here too to get both side by side. In the validation function delete the whole option if the reset button is present in … Read more
