I put the following code in the fuction.php file in the xxx- child theme folder. It doesn"t work, but it works in the parent theme.
I want to put it in a child theme, so as not to add this code to upgrade the parent theme. Excuse me, where does it need to be changed?
<?php
// html
add_action("init", "html_page_permalink", -1);
function html_page_permalink() {
global $wp_rewrite;
if ( !strpos($wp_rewrite->get_page_permastruct(), ".html")){
$wp_rewrite->page_structure = $wp_rewrite->page_structure . ".html";
}
}
//
function nice_trailingslashit($string, $type_of_url) {
if ( $type_of_url != "single" && $type_of_url != "page"&& $type_of_url != "paged"&& $type_of_url != "single_paged" )
$string = trailingslashit($string);
return $string;
}
add_filter("user_trailingslashit", "nice_trailingslashit", 10, 2);
?>
