How do I conditionally enqueue script for CPT single post type with plugin?

I’m writing a plugin that defines its own CPT “properties” and I want to enqueue a script specifically in single posts.

It runs without my attempt at a conditional statement just fine but I don’t need it to load on every page so I’d like to make this conditional.

This code is in my plugin root just after my includes.

if ( 'properties' == get_post_type() ) {
    if (wp_script_is('owl.carousel.js', 'enqueued')) {
        return;
    } else {
        wp_register_script('owl.carousel.min.js', plugin_dir_url(__FILE__) . 'js/owl.carousel.min.js');
        wp_enqueue_script('owl.carousel.min.js');
    }
}

I’ve also tried is_sigular('properties') but that didn’t work either.

I must be missing something silly…

Make sure your code runs in wp_enqueue_scripts action hook.

Also checkout your script handle 'owl.carousel.js'. In wp_script_is(), it is not the same than in the 2 later functions in which you enter it as 'owl.carousel.min.js'.

add_action( 'wp_enqueue_scripts', 'enqueue_properties_scripts' );

function enqueue_properties_scripts() {
    if ( 'properties' === get_post_type() ) {
        if ( wp_script_is( 'owl.carousel.min.js', 'enqueued' ) ) {
            return;

        } else {
            wp_register_script( 'owl.carousel.min.js', plugin_dir_url( __FILE__ ) . 'js/owl.carousel.min.js' );
            wp_enqueue_script( 'owl.carousel.min.js' );
        }
    }
}
