Adding your own filter to the WordPress Media Library - Cobbled Code

Yay! A nice short and helpful intro by Daniel Bachhuber on how to add a custom taxonomy dropdown filter to a WordPress media view.

I find good examples of working with the not-so-new Media Uploader quite hard to come by. This modified version of the example adds an “Uploaded to this post” filter for a custom media view. Really helpful when wading through lots of uploads.

(function(){
	/**
	 * Create a new MediaLibraryUploadedFilter.
	 */
	var MediaLibraryUploadedFilter = wp.media.view.AttachmentFilters.extend({

		id: 'media-attachment-uploaded-filter',

		createFilters: function() {

			var filters = {};

			filters.all = {
				// Todo: String not strictly correct.
				text:  wp.media.view.l10n.allMediaItems,
				props: {
					status:  null,
					type:    'image',
					uploadedTo: null,
					orderby: 'date',
					order:   'DESC'
				},
				priority: 10
			};

			filters.uploaded = {
				text:  wp.media.view.l10n.uploadedToThisPost,
				props: {
					status:  null,
					type:    null,
					uploadedTo: wp.media.view.settings.post.id,
					orderby: 'menuOrder',
					order:   'ASC'
				},
				priority: 20
			};

			filters.unattached = {
				text:  wp.media.view.l10n.unattached,
				props: {
					status:     null,
					uploadedTo: 0,
					type:       'image',
					orderby:    'menuOrder',
					order:      'ASC'
				},
				priority: 30
			};

			this.filters = filters;
		}
	});

	/**
	 * Extend and override wp.media.view.AttachmentsBrowser
	 * to include our new filter
	 */
	var AttachmentsBrowser = wp.media.view.AttachmentsBrowser;
	wp.media.view.AttachmentsBrowser = wp.media.view.AttachmentsBrowser.extend({
		createToolbar: function() {

			// Make sure to load the original toolbar
			AttachmentsBrowser.prototype.createToolbar.call( this );

			this.toolbar.set(
				'MediaLibraryUploadedFilter',
				new MediaLibraryUploadedFilter({
					controller: this.controller,
					model:      this.collection.props,
					priority:   -100
				})
				.render()
			);
		}
	});
})()

  1. This was very helpful and you’re correct that finding good examples of customizing the media section are hard to find. I had set my default media view to be “uploaded to this post” so I had to move a couple of things around for my scenario but this was basically exactly what I was looking for and it’s working great. Thanks!
