1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
/** * Edit hreflangs in Polylang */ add_filter('pll_rel_hreflang_attributes', 'edit_polylang_hreflang_attributes', 10, 1); function edit_polylang_hreflang_attributes ($hreflangs) { if (is_category()) { foreach ( $hreflangs as $lang => $url ) { $hreflangs[$lang] = str_replace('/./', '/', $url); } } return $hreflangs; } |
As a result, we get these attributes:
