Always develop with WP_DEBUG set to TRUE. You’ve a typo: array_push($valid_input[$id], $input[$id]; (missing ) after the array_push) You can’t push to arrays that are not … arrays. // So, check this before pushing: $valid_input[$id] = ! is_array( $valid_input[$id] ) ?

When … Read more
I am satisfied with Nikolay Yordanov’s answer. Just generalizing the solution. Yes, we can update WordPress options programmatically. WordPress saves options in wp_options table. wp_options holds two rows option_name and option_value to store key and value respectively. We need right option_name and a way to save value in wp_options table. As we know, we can … Read more
Store the options in a single array and write your plugin as a class. Load the options in the constructor and save it as a member variable and you’ll have access to it everywhere in the plugin.
You could use a JavaScript alert to do what you’re asking, but the only way I can think of doing it would likely be a fair chunk of unnecessary added complexity.
