Yes it is. But you have to know the exact taxonomy’s slug, since colors are not like preserved terms to be generated programmatically. Here is an example of how to do it: // run our function when a post is published add_action(‘save_post’,’update_my_taxonomies’); function update_my_taxonomies($post_id){ // Check if the post has a particular taxonomy if(has_term( ‘blue’, … Read more
It happens when the foreach() is fed with an invalid entry, because there is no term returned. To prevent this, wrap your loop inside a conditional: // Get the terms( categories ) for the portfolio item $terms = get_the_terms( $post_item->ID, ‘portfolio_categories’ ); if(is_array($terms) || is_object($terms)){ foreach( $terms as $term ) { // some code here … Read more
I’m not sure if it’s possible to directly query the terms, So I’m gonna write a workaround for you. The WP_Query(); accepts an argument named terms. You can pass term IDs as an array to this argument. Let’s first fetch a list of terms in the first taxonomy, then query based on these terms: $terms … Read more
Here: $search_values[‘tax_query’] = array ( You’re resetting the value of tax_query for every item in the foreach loop. It’s also being set to an invalid value: Important Note: tax_query takes an array of tax query arguments arrays (it takes an array of arrays). This construct allows you to query multiple taxonomies by using the relation … Read more
So here’s some info for any other people with this issue. get_terms will not use the number parameter under certain conditions, such as if you pass in a parent parameter or if the hierarchical parameter is true. In these cases I have tried two workarounds, neither very good. You can call get_terms then do an … Read more
I see two ways to go about it, both quite similar. A) You can collect IDs of displayed posts in an array and then exclude those with post__not_in query parameter like so: $years_loop = get_terms( array( ‘taxonomy’ => ‘works_year’, ‘orderby’ => ‘slug’, ‘order’ => ‘DESC’, ) ); // array for displayed posts, we will update … Read more
I found the answer CSS Tricks and it works. Here’s the code I use. $terms = get_the_terms( $post->ID , ‘portfolio_user’ ); foreach ( $terms as $term ) { echo $term->slug; }
The term_link filter has a different signature for its callback function than the page_link filter, meaning the arguments in your callback are different. (Also note you’ll need to explicitly set the argument number when you call add_filter because by default add_filter will only setup 1 argument. For example: add_filter( ‘term_link’, ‘lqd_series_link’, 10, 3 ); // … Read more
You will have bugs like this. because you are not sanitizing the title with sanitize_title(). And you are not checking for duplications with wp_unique_term_slug() Bugs tests: Add spaces in the name and see the slug with spaces. After you add the sanitize_title() add term with comma 5,5 add term with space 5 5 results with … Read more
This should work <?php if ( ! empty( $terms ) && ! is_wp_error( $terms ) ) : foreach( $terms as $term) : if ($term->parent != 0){ echo $term->name; } endforeach; endif; ?> In the loop of the terms it prints only terms that have a ‘parent term’ given by $term->parent!=0 which means that the term … Read more
