wp_sprintf_l filter allows you to modify the default list item separators used in lists employing the
%l specifier — such as when using the
the_taxonomies() template tag. When we say “separators”, we’re talking about the punctuation and/or punctuation + words used to grammatically space items in a list.
- If there are two taxonomy terms, the separator would be ‘ and ‘, e.g. ‘Something and Something Else’
- If there are three or more terms, the separator ‘, ‘ would be used up until the last term, then the separator used would be ‘, and ‘, e.g. ‘Something, Something Else, and Something Else Again’
Important note: You should exercise caution modifying the default separators as translators use them as a guide.
wp_sprintf_l accepts a single argument that takes the form of an array. Each key/value pair in the array specifies a different type of list item separator:
', and '
' and '
Let’s say you’re one of those people who just can’t stand the serial/Oxford comma, the following will modify the
between_last_two key in the
wp_sprint_l separators array.
