This snippet shows all posts with their yoast primary category. What do I have to add to get only the posts with the primary category ‘Prezi’ or ‘Kahoot’?

$primary_term = get_post_meta(get_the_ID(), '_yoast_wpseo_primary_category', true);
$the_query = new WP_Query(array(
    'post_type' => 'post',
    'posts_per_page' => 3,
    'post_status' => 'publish',
    'category_name' => $primary_term,
    'orderby' => 'rand',
    'order' => 'asc',
));

@rickymccallum87 Thans for your reply! I’m going to try the validator. I’ve found some typing errors indeed and fixed those. I’m trying to understand the messags, but not all of them become clear already so I share those with you. Here are my thoughts.

This is the new source code without the typing errors.

Messages 1, 2 and 3, are caused by the fact that I copied the snipped out of the source code where the problem occurs. The missing elements are in the header.php of the site.

Message 4: I don’t know what is meant by trailing slash on void elements.

Message 5: What is meant by the open elements? Are that the <article> in message 6? and first div in the sourcecode?

Message 7: Because of the div (message 5) <article> is expected to be closed, but isn’t (see message 6). But it’s because of that same div, the position of </article> is considered to be weird.

Message 8: There is a </div> to many in the coding: the div of message 5. Due to that div, the closing div of message 8 is considered to be one to many. (But the closing div of message 5 is causing a lot of trouble.)


I hope you can follow my thougths and that can you explain the things I don’t understand, especially message 4.

Kind regards!

@sirlouen Thanks for your quick reply and the link you’ve shared in it. I’ve seen the page, but for me it’s not exactly clear how to use it. In the examples at the page I didn’t see how the echo avatar for example. I’m not so much in to coding, but when I’ve got an idea how to start, I will find my way and can add extra code.

@sirlouen

You were right. With the following code snippet I got it working as I wanted. Thanks for your tip! The option B also works when there is just one single category selected. It automatically becomes the primary category,

<?php                                                

$primary_term_id = yoast_get_primary_term_id( 'category', $post_id );

$term = get_term( $primary_term_id ); // Get the term object to access its name

if ( $term->name == 'Prezi' || $term->name == 'Kahoot' ) {

    echo "A.";

} else {

    echo "C";

}

  ?>       

@sirlouen Thanks for your quick reply. Do you think i’ve to copy the post to the Yoast plugin support or can my thread moved toward that forum?

I do now! I’ve found this code snippet that does what it needs to do!
category_parent); if (!empty($parent)) {echo '' . $parent;} else {echo '' . $category[0]->cat_name;} ?>

Kind regards,
Timothy

Thanks for helping me out. The other forum(s) you’ve mentionned, I didn’t know that until now. Those can be a big help in the future too. Like you ‘ve been last days.
