I have the following I'm trying to enqueue in functions.php

wp_enqueue_script( 'param-example', 'https://domain.com/example?f=j&s=w&c=t', array(), null );

Except WordPress is escaping the ampersands in the HTML which is breaking the script.

How can I prevent WordPress from escaping the URL in wp_enqueue_script?

The other examples that seem close to this question haven't worked.

  • Are you sure that's what is breaking your script? I have an ampersand in mine and it's working fine.

  • Can you elaborate how is breaking the script when it's escaped?

WordPress can automatically add the query variables for you. Instead of directly writing the query arguments, you can use it this way:

$args = array(
        'f' => 'j',
        's' => 'w',
        'c' => 't'
wp_enqueue_script( 'param-example', add_query_arg( $args, 'https://domain.com/example') );

This is your solution, since according to code reference, the return value is unescaped by default.

  • This isn't what's needed. The variables don't need to be unescaped, the ampersands between the variables need to be. This doesn't do that. May 5 '18 at 3:16

Another solution is to create a hook to target specific URLS.


// Add to functions.php, or to a Plugin file.
// Change, CHANGE_ME.com to Urls you want to stop wordpress from converting.
add_filter('clean_url', 'hook_strip_ampersand', 99, 3);
function hook_strip_ampersand($url, $original_url, $_context) {
    if (strstr($url, "CHANGE_ME.com") !== false) {
        $url = str_replace("&", "&", $url);

    return $url;

  • How do you then enqueue the script? wp_enqueue_script( 'param-example', $url ); doesn't seem to do it. May 5 '18 at 3:18
