Multisite Taxonomy Widget

Display a recent posts-widget of all your posts in your blog-network which have a specific tag, category or any other built-in or custom taxonomy.

Please keep in mind that the version of the Multisite Taxonomy Widget at GitHub is a work in progress.

Download the latest stable version from the WordPress Plugin Directory.

Need help? Check out the forum first! If you find any bugs then I would very much like to hear about the issue.

How to use the widget

After the activation of the plugin you'll find a new widget called Multisite Taxonomy in Appearance > Widgets (/wp-admin/widgets.php).

Once you dragged the widget in one of your sidebars you can fill in various parameters for customizing the output of the widget:

  1. Title

    This is the widget title. Leave it empty if you don't need to show a title above the widget.

  2. Taxonomy

    This is the type of the taxonomy such as category, tag and so on.

  3. Name

    This is the most important parameter. If you want the widget to search for all posts with the tag Cool post for example put cool-post in here because the plugin uses the slug-form of the taxonomies and the slug of the Cool post-taxonomy is probably saved as cool-post. But you should check that anyway.

  4. Limit

    You can limit the output with this parameter. This should be a number > 0. If you want to show all posts of the specific taxonomy you can set -1 but it is not recommended.

  5. Thumbnail

    You can set any positive number here if you want to show thumbnails. If you don't like them leave this field empty or fill in a 0.

How to use the shortcode

Use the shortcode [mtw_posts] if you'd like to show a list of posts of your network in the content where usually a normal widget cannot be placed. The parameters are similar to those for the widget. You can use taxonomy, name, limit and thumbnail as arguments.

With this in mind you can write

[mtw_posts taxonomy="category" name="test"]

if you want to show the last 10 (because this is standard when limit is not set) posts in the category test. If you prefer tags and you don't want to see thumbnails use:

[mtw_posts taxonomy="post_tag" name="test" thumbnail="0"]

And if you want to show the last 5 posts of a post type which has a custom taxonomy called product_category, you could use something like:

[mtw_posts taxonomy="product_category" name="test" limit="5"]

How to use the filter hooks

You can use filters if you want to override the output of the functions. The are 4 filters available:

  1. mtw_formatelements_output_filter

    There is a function which calls this filter after adding 4 elements to an array of format-elements: before_mtw_list/after_mtw_list (<ul>/</ul>) and before_mtw_item/after_mtw_item (<li>/</li>) so you can override this.

  2. mtw_thumbnail_output_filter

    You can create your customized output of the thumbnail. This filter gives you access to a post-object and an array of parameters and returns the string from your function if you define one.

  3. mtw_shortcode_output_filter

    You can create your customized output of the list-item when a shortcode is used. This filter gives you access to a post-object and an array of parameters and returns the string from your function if you define one.

  4. mtw_widget_output_filter

    You can create your customized output of the list-item when a widget is used. This filter gives you access to a post-object and an array of parameters and returns the string from your function if you define one.
