TukuToi Hierarchical Posts Tree View

ხდკ

How can I change the Post Type queried in the default Widget?

Using the tkt_htv_default_post_type filter you can alter the Default Widget’s Queried Post Type.
The filter accepts one argument, an array of Post Type Slug and Post Type name.
To change the default, first unset the existing array.

Example usage:

add_filter('tkt_htv_default_post_type', 'my_default_post_type');
function my_default_post_type( $post_type ){

    unset($post_type);

    $post_type['post_type_slug'] = 'Post Type Name';

    return $post_type;

}

Can I have more than Widget, each Widget for a separate Hierarchical Post Type?

Yes. You can use the tkt_htv_widgets filter to add as manu additional Widgets you want.
The filter accepts one argument, being an array of Post Type Slugs and Post Type Names.

Example Usage:

add_filter('tkt_htv_widgets', 'my_additional_widgets');

function my_additional_widgets( $widgets ){

    $widgets['another-post-type'] = 'Another Post Type';
    $widgets['yet-another-post-type'] = 'Yet Another Post Type';

    return $widgets;

}

I do not see all my Hierarchical Posts in the Tree View

This Plugin shows by default the first 100 Top Level Posts, and only if they have children.
Thus, to show more Posts, you can either use a filter to change the default amount of posts shown,
or paginate using URL parameters.

To paginate using URL paramters, you can use these URL params:
_per_page (?_per_page=100)
_offset (?_offset=100)
For example, this query will show the next 100 posts:
/?_per_page=100&_offset=100

If you want to increase the amount of Posts shown by default, or the offset, you can use the filters documented here:
tkt_htv_pagination_default
tkt_htv_offset_default

I get the message “You have no hierarchical {Post Type} message”

This can happen for 2 reasons:
– You indeed have not a single Post that has Children Posts.
– Or, you have more than 100 posts, and the first 100 Posts have no Children assigned.

In the first case, of course you need to assign some Posts as children to others.
In the second case, when you have children posts, but see no results, it is because of the Pagination.
By default, this plugin shows only the first 100 Top Level Posts that have children.
If it so happens that your first 100 Posts returned by the query have no children, you may use pagination and offset URL paramters,
in order to see the subsequent batches of results. For example, if your first Post with a Child is number 156 in the results,
you would have to add these URL parameters to see the Post in the Widget:
/?_per_page=100&_offset=100

What other filters are available?
