I know that I can use the following function to remove the version from all .css and .js files:

add_filter( 'style_loader_src', 'sdt_remove_ver_css_js', 9999 );
add_filter( 'script_loader_src', 'sdt_remove_ver_css_js', 9999 );
function sdt_remove_ver_css_js( $src ) {
    if ( strpos( $src, 'ver=' ) )
        $src = remove_query_arg( 'ver', $src );
    return $src;

But I have some files, for instance style.css, in the case of which I want to add a version in the following way:

function css_versioning() {
    wp_enqueue_style( 'style',
        get_stylesheet_directory_uri() . '/style.css' ,
        filemtime( get_stylesheet_directory() . '/style.css' ),
        'all' );

But the previous function removes also this version. So the question is how to make the two work together?


You can check for the current handle before removing the version.

Here's an example (untested):

add_filter( 'style_loader_src',  'sdt_remove_ver_css_js', 9999, 2 );
add_filter( 'script_loader_src', 'sdt_remove_ver_css_js', 9999, 2 );

function sdt_remove_ver_css_js( $src, $handle ) 
    $handles_with_version = [ 'style' ]; // <-- Adjust to your needs!

    if ( strpos( $src, 'ver=' ) && ! in_array( $handle, $handles_with_version, true ) )
        $src = remove_query_arg( 'ver', $src );

    return $src;

Since this question was written, a lot has changed with WordPress. Here is a new way to prevent WordPress from displaying its version number:

// remove version from head
remove_action('wp_head', 'wp_generator');

// remove version from rss
add_filter('the_generator', '__return_empty_string');

// remove version from scripts and styles
function remove_version_scripts_styles($src) {
    if (strpos($src, 'ver=')) {
        $src = remove_query_arg('ver', $src);
    return $src;
add_filter('style_loader_src', 'remove_version_scripts_styles', 9999);
add_filter('script_loader_src', 'remove_version_scripts_styles', 9999);

No editing required. Add to functions.php and done. Or add via simple custom plugin. The choice is yours! :)

  • Nice! Unfortunately it doesn't answer OP's question on how to keep it for one certain CSS. – leymannx May 28 '19 at 20:34
