I realized this has to do with my custom code implementation which was made to grab the primary category of a post as defined by Yoast.
This is the current code.
Can you let me know how can I replicate this same function to grab the primary category as defined by Rankmath? Thanks
function get_primary_taxonomy_id( $post_id, $taxonomy ) {
$prm_term = '';
if (class_exists('WPSEO_Primary_Term')) {
$wpseo_primary_term = new WPSEO_Primary_Term( $taxonomy, $post_id );
$prm_term = $wpseo_primary_term->get_primary_term();
}
if ( !is_object($wpseo_primary_term) && empty( $prm_term ) ) {
$term = wp_get_post_terms( $post_id, $taxonomy );
if (isset( $term ) && !empty( $term ) ) {
return wp_get_post_terms( $post_id, $taxonomy )[0]->term_id;
} else {
return '';
}
}
return $wpseo_primary_term->get_primary_term();
}
Hello,
Thank you so much for getting in touch.
Can you check if you can select your primary categories when you edit your post like the screenshot below?
Thank you, and looking forward to your update.
Hi Roel.
Thanks for getting in touch.
I’m able to change and save the primary category using that dropdown, but I’m displaying the post primary category on the frontend using the function I shared above. Because it’s using Yoast’s variable it doesn’t work now. How can I replicate it to RankMath? I believe it has do with “WPSEO_Primary_Term”?
Thanks!
Hello,
We apologize for the delay and any inconvenience this may cause.
To display the primary category name for the post, please place the following function in your Themes > functions.php
/**
* Display Primary Category Name of post
* @param $term string The term name
* @param $postID int The post ID
*/
function RM_get_post_primary_category($post_id, $term='category', $return_all_categories=false){
$return = array();
if (class_exists('WPSEO_Primary_Term')){
$wpseo_primary_term = new WPSEO_Primary_Term( $term, $post_id );
$primary_term = get_term($wpseo_primary_term->get_primary_term());
if (!is_wp_error($primary_term)){
$return['primary_category'] = $primary_term;
}
}
if (empty($return['primary_category']) || $return_all_categories){
$categories_list = get_the_terms($post_id, $term);
if (empty($return['primary_category']) && !empty($categories_list)){
$return['primary_category'] = $categories_list[0]; //get the first category
}
if ($return_all_categories){
$return['all_categories'] = array();
if (!empty($categories_list)){
foreach($categories_list as &$category){
$return['all_categories'][] = $category->term_id;
}
}
}
}
return $return;
}
To Display the Primary category name for the post at the front-end use the following snippet
// get the post ID
$post_id = get_the_ID();
$post_categories = RM_get_post_primary_category($post_id, $term='category', $return_all_categories=false);
// Display Primary category name
echo $post_categories['primary_category']->name;
