Modify the “article:tag” Keywords / Names

Here is a filter I use on UnderwaterFocus to remove the ‘Wiki-‘ prefix from WordPress tags. This snippet hooks the filter_wpsso_tags() function to the ‘wpsso_tags’ filter, and the function receives an array of tags, which it transforms and returns. You could also use the same technique to add and/or remove certain tags.


add_filter( 'wpsso_tags', 'filter_wpsso_tags', 10, 1 );

function filter_wpsso_tags( $tags = array() ) {
        foreach ( $tags as $num => $tag_name ) {
                $tag_name = preg_replace( '/^wiki-/i', '', $tag_name );
                $tags[$num] = $tag_name;
        }
        return $tags;
}

add_filter( 'wpsso_tags', 'filter_wpsso_tags', 10, 1 );

function filter_wpsso_tags( $tags = array() ) {

foreach ( $tags as $num => $tag_name ) {

$tag_name = preg_replace( '/^wiki-/i', '', $tag_name );

$tags[$num] = $tag_name;

}

return $tags;

}
