And how to hide if the is no taxonomy associated with a post
Hello,
Thank you for contacting Rank Math for help with adding a list of all your custom terms as a variable in the SEO meta of your post.
Rank Math does not have a variable to display the list of terms as a string. You will have to create a custom variable to display list of terms. I have created the custom variable ‘%cat_terms%’ to do it. Please add the following code snippet to your website and replace %customterm(artist)% with %cat_terms%.
/**
* Action: 'rank_math/vars/register_extra_replacements' - Allows adding extra variables.
* Snippet to register variable that will return the number of posts in the current term
*/
add_action('rank_math/vars/register_extra_replacements', function () {
rank_math_register_var_replacement(
'cat_terms',
[
'name' => esc_html__('Category Terms', 'rank-math'),
'description' => esc_html__('Number of posts in the current term', 'rank-math'),
'variable' => 'cat_terms',
'example' => cat_terms_callback(),
],
'cat_terms_callback'
);
});
function cat_terms_callback()
{
global $post;
if ( !has_term('', 'category')) return; //replace 'category' with your custom taxonomy name.
$post_id = $post->ID;
$terms_list_objects = get_the_terms( $post_id, 'category'); //replace 'category' with your custom taxonomy name.
$terms_list_array = array_map(function ($object) { return $object->name; }, $terms_list_objects);
$terms_list_string = implode(', ', $terms_list_array);// replace ', ' with your preferred spacer
return $terms_list_string;
}
In the code snippet, find the lines to replace ‘category’ with ‘artist’. You can follow this guide for how to add a code snippet to your website: https://rankmath.com/kb/wordpress-hooks-actions-filters/
Hope that helps. Please let us know if you have questions.
Thank you very much it works but one more thing, for spacer if there is more than Five Tags it will be like this “Song name By Artist 1, Artist 2, Artist 3, Artist 4, Artist 5” I want to be able to add FT. “Featuring” so if i add “FT.” to spacer and will look like this “Song name By Artist 1 FT. Artist 2 FT. Artist 3 FT. Artist 4 FT. Artist 5”
I will like it do look like this “Song name By Artist 1 FT. Artist 2, Artist 3, Artist 4 & Artist 5” is this possible.?
