Retrieve taxonomy terms and use them in a loop
I have the following code which shows a list of other posts within a single post on the front-end. The $postarea is input as a custom text field in the post back-end. This works but I would like to automate it as the $postarea is the just same as the taxonomy term I select for the post, i.e. if the post is about New York I would select ‘New York’ in the taxonomy field and input “new-york” in the custom text field.
I’ve tried setting $postarea to be the same as the taxonomy(s) selected for that post but get error messages about it being an array or object when it is expecting a string. Any help would be appreciated.
// define query parameters based on attributes $options = array( 'post_type' => 'post', 'posts_per_page' => -1, 'orderby'=> 'title', 'order' => 'ASC', 'category_name' => 'things-to-do', 'relation' => 'AND', 'tax_query' => array( array( 'taxonomy' => 'location', 'field' => 'slug', 'terms' => $postarea ), ),
