Hi

I need a function which output only categories of a specific parent category. I have copied the “getCategoryBlock” in the class.entry-output.php and named it to “getAbteilungen”. But I don’t understand the $categories = $this->getCategory(). I only know the “get_categories()” function of wordpress. There I can say (for example) child_of = 3. How can I do this for the connections categories?

Thanks for your help!

Regards

Sorry, right now this is not possible unless you use unsupported, still under development code.

To call the raw data you would use this:

// Grab an instance of the Connections object.
$instance = Connections_Directory();

$terms = $instance->term->get( array( 'child_of' => 3 ) );

$terms will contain an array of the children of category ID 3 which you can loop thru and output.

Hope that helps!

Sorry, I think I mis-read my code, try this instead:

$terms = cnTerm::get( array( 'child_of' => 3 ) );

re: If I would get the name of the category I can get it with $term->name (in a foreach loop)?
Yes, the term name will be included in the results.

@ Fabrice

you know, It would be really helpful to you if I would actually read better!

Here’s a link to the function you’re using:
https://github.com/Connections-Business-Directory/Connections/blob/8.1.3/includes/class.terms.php#L1022

The phpDoc for the function starts here:
https://github.com/Connections-Business-Directory/Connections/blob/8.1.3/includes/class.terms.php#L883

So my error, again, is providing you with the wrong way to use the function … it should be:

$terms = cnTerm::get( 'category', array( 'child_of' => 3 ) );

I wrote the code but I don’t actually use it, yet, and it’s been a couple months since I did write it, so I’m just forgetting how it works. It’s no excuse for the bad info I’m giving you but it is the reason. I apologize! And if I’m wrong again, hopefully the phpDoc I linked to will give you the answers you need assuming I have no errors in it.

Oh the design reason behind requiring the need to define category is this rewrite should enable me to support custom taxonomies in the future just like WordPress does now.

Hey Steven! Now I get the correct categories, but all categories which are “child_of = x”. Is there some query to only display the selected categories from a user?

@ Fabrice

When you say user, do you mean the categories assigned to an entry?

This would work:

// Grab an instance of the Connections object.
$instance = Connections_Directory();

$terms_r = $instance->term->getTermRelationships( $entry->getID() );

$terms = cnTerm::get( 'category', array( 'child_of' => 73 ) );

foreach ( $terms as $term ) {
    if ( ! in_array( $term->term_id, $terms_r ) ) continue;

    echo $term->name;
}
