Getting author’s nickname as meta value

After review, I would expect your code to work properly: to only save the creating author’s nickname, and not override it later.

get Custom field label (select/dropdown) on front end

You can set the keys of the array to be user-friendly, but more appropriate would be to define the options array in a function, and then use that function in both the backend and frontend (untested): Array function product_condition_array() { return array( ‘new’ => __( ‘New’, ‘woocommerce’ ), ‘like_new’ => __( ‘New other (see description) … Read more

How to modify default tags in wp_head()

Here’s a simplified example of using it : add_filter( ‘document_title_parts’, ‘filter_document_title_parts’, 10, 1 ); function filter_document_title_parts( $title_parts … Read more
