I am using the Transients API to hold the output for a gallery plugin's shortcode I created. Due to the number of images used and different layouts needed, the transient name looks lik the following:

_transient_galleries_single_shortcode_5183five

So - the int portion is the post ID it is referencing and the five is this specific shortcode's column setting. Where I'm running into trouble is flushing these shortcodes on-save of the referenced galleries.

What I'd normally do is something like following:

function galleries_delete_transient($post_id) {
    switch (get_post_type()) {
        case 'galleries':
            delete_transient('galleries_single_shortcode_'.$post_id);
        break;
    }
}
add_action('save_post','galleries_delete_transient');

The problem being here is that the column setting can be different based on a certain page's needs - so I was wondering if there is any type of wildcard I can use here to make this a bit more dynamic (to just clear all of them - something like delete_transient('galleries_single_shortcode_'.$post_id%);). Any help would be greatly appreciated. Thanks!

Update

Complete shortcode function added for clarity how everything is constructed:

function galleries_single_shortcode($atts, $content = null) {
    extract(shortcode_atts(array(
            "id"     => '',
            "columns" => 'four'
    ), $atts));

    global $galleries_options;

    $galleries_single_shortcode_output = get_transient('galleries_single_shortcode_'.$id.$columns);
    if ($galleries_single_shortcode_output === false) {

        ob_start();

        // OUTPUT HERE

        $galleries_single_shortcode_output = ob_get_contents();

        ob_end_clean();

        set_transient('galleries_single_shortcode_'.$id.$columns, $galleries_single_shortcode_output, 60 * 60 * 24);

    }


    return $galleries_single_shortcode_output;
}
add_shortcode('galleries_single', 'galleries_single_shortcode');
