What I’m trying to do is use less css with WordPress.
You’re supposed to link to your .less files with the rel attribute set to ‘stylesheet/less’. But I can’t figure out how to alter the code that enqueue_style outputs.
Is there a way to apply a filter and affect the output?
EDIT: If anyone is curious as to how I ended up getting this to work, here is the code snippet:
function enqueue_less_styles($tag, $handle) {
global $wp_styles;
$match_pattern = '/\.less$/U';
if ( preg_match( $match_pattern, $wp_styles->registered[$handle]->src ) ) {
$handle = $wp_styles->registered[$handle]->handle;
$media = $wp_styles->registered[$handle]->args;
$href = $wp_styles->registered[$handle]->src . '?ver=" . $wp_styles->registered[$handle]->ver;
$rel = isset($wp_styles->registered[$handle]->extra["alt']) && $wp_styles->registered[$handle]->extra['alt'] ? 'alternate stylesheet' : 'stylesheet';
$title = isset($wp_styles->registered[$handle]->extra['title']) ? "title="" . esc_attr( $wp_styles->registered[$handle]->extra["title'] ) . "'" : '';
$tag = "<link rel="stylesheet" id='$handle' $title href="https://wordpress.stackexchange.com/questions/20876/$href" type="text/less" media="$media" />";
}
return $tag;
}
add_filter( 'style_loader_tag', 'enqueue_less_styles', 5, 2);
