I'm trying to access widget information saved in the wp_options table.
I printed it out:

add_filter('the_content', function(){
    $res = get_option('widget_my_widget');

And it outputted this:

Array ( [2] => Array ( [title] => asian kung-fu generation [description] => awesome band ) [_multiwidget] => 1 )

My question: is the data always stored at index 2? If not, how can I access the data without worrying if it gives me the correct one or not?

  • What happens when you have two instances of the widget?

  • I tried it, and there's index 2 and then index 3 for the second instance. Jan 31 '13 at 5:44

It seems that the index value goes incrementing and we add/remove instances of the widget.

To make sure the correct data is grabbed, I can only think of checking inside the widget data itself through some control variable, something like:

Array ( 
    [2] => Array ( 
        [title] => asian kung-fu generation 
        [description] => awesome band 
        [var-of-control] => true (or some other convention) 
    [_multiwidget] => 1 

Or even by title. The following function does this checking:

add_filter( 'the_content', function(){
    $res = get_option( 'widget_my_widget' );
    $check = check_array_key_value( $res, 'title', 'asian kung-fu generation' );
    print_r( $check );

function check_array_key_value( $array, $key, $val ) 
    foreach ( $array as $item )
        if ( isset( $item[$key] ) && $item[$key] == $val)
            return $item;
    return false;
