A class to copy into your WordPress plugin, to make adding custom post type counts to the At a Glance dashboard widget considerably easier.
WordPress 3.8 introduced the At a Glance dashboard widget, as a replacement for the Right Now widget. The new widget contains an action hook, dashboard_glance_items, which allows developers to insert extra list items into the widget. Although grabbing the number of entries of a certain post type, and maybe a specific status within that post type, and displaying within markup is not tricky, it can't be done as minimally as what this class allows. Add in the desire for wanting to include counts for multiple post types, or multiple statuses, and this class comes into its own. See the Usage section for how simple the code is.
This isn't a WordPress plugin on its own, so the usual instructions don't apply. Instead:
- Copy
class-gamajo-dashboard-glancer.phpinto your plugin. It can be into a file in the plugin root, or better, anincludesdirectory. - Ensure the class file is available to whichever code will be using it.
// Require the new class (change to your correct path)
if ( ! class_exists( 'Gamajo_Dashboard_Glancer' ) ) {
require plugin_dir_path( 'includes/class-gamajo-dashboard-glancer.php' );
}or:
- Tell Composer to install this class as a dependency:
composer require gamajo/dashboard-glancer - Recommended: Install the Mozart package:
composer require coenjacobs/mozart --devand configure it. - The class is now renamed to use your own prefix, to prevent collisions with other plugins bundling this class.
Within your plugin files, either as a function, or as part of a class, implement something like:
// Hook into the widget (or any hook before it!) to register your items.
add_action( 'dashboard_glance_items', 'prefix_add_dashboard_counts' );
function prefix_add_dashboard_counts() {
$glancer = new Gamajo_Dashboard_Glancer;
$glancer->add( 'my_cpt' ); // show only published "my-cpt" entries
}That's it!
// Lots of examples of how to add given here, you only need one for each combination of
// multiple post types and multiple statuses.
add_action( 'dashboard_glance_items', 'prefix_add_dashboard_counts' );
function prefix_add_dashboard_counts() {
$glancer = new Gamajo_Dashboard_Glancer;
$glancer->add( 'my_cpt' ); // show only published "my-cpt" entries
$glancer->add( 'my_cpt', 'draft' ); // show only draft "my-cpt" entries
$glancer->add( 'my_cpt', array( 'publish', 'draft' ) ); // show only published and draft "my-cpt" entries
// Show only published and draft entries for all three post types
$my_post_types = array( 'ingredients', 'recipes', 'meal_plan' );
$glancer->add( $my_post_types, array( 'publish', 'draft' ) );
// Supports custom statuses as well
$my_statuses = array( 'pitch', 'assigned', 'in-progress', 'needs-edit', 'ready-to-publish' );
$glancer->add( 'post', $my_statuses );
}Remember, that code above shows lots of examples of how you can add multiple post types and multiple statuses in one go. For the simplest case, you would instantiate the class, and do a single call to the add() method and that's it.
The textual label is taken from the custom post type registration itself. It will use the singular label (e.g. Story) if the count is exactly 1, or the plural name (e.g. Stories) otherwise. If the status is not publish, then it will append the status to disambiguate. If the item count is zero, then nothing will show up, to keep visual clutter to a minimum.
The class will automatically output any items still registered, at priority 20 of the dashboard_glance_items action hook. If you want to output at an earlier priority, then just call the show() method on the object that has the items registered, when hooked in to that earlier priority (here, 8):
add_action( 'dashboard_glance_items', 'prefix_add_dashboard_counts', 8 );
function prefix_add_dashboard_counts() {
$glancer = new Gamajo_Dashboard_Glancer;
$glancer->add( 'my_cpt' ); // show only published "my-cpt" entries
$glancer->show();
}Once show() is called, all registered items become unregistered, so that show() being called again (at priority 20, or manually) will not result in duplicate items showing on the widget.
The class is not a singleton, so if you add items in one function, but want to show early in another, you'll need to pass the object across, likely via a global variable. As a non-singleton, you could also register some items to show early, and some to show late, by instantiating two objects from the Gamajo_Dashboard_Glancer class, but only explicitly calling show() on one of them.
This project also includes the Gamajo_Dashboard_RightNow class which is an extension of the main Gamajo_Dashboard_Glancer class. This can be instantiated and added to within a function hooked to the right_now_content_table_end hook, to provide the same information in the WordPress 3.7 Right Now widget.
// Hook into the widget (or any hook before it!) to register your items.
add_action( 'right_now_content_table_end', 'prefix_add_dashboard_counts_old' );
function prefix_add_dashboard_counts_old() {
$glancer = new Gamajo_Dashboard_RightNow;
$glancer->add( 'my_cpt' ); // show only published "my-cpt" entries
}Contributions are welcome - fork, fix and send pull requests against the develop branch please.
GPL-2.0+, so feel free to use in any WordPress project. Let me know when you do (not a requirement of usage) as I'd love to know where my code is being used!
