Load scripts for a one product

Hello,

Try loading scripts for a certain product with enable/disable a custom checkbox on product edit page.
So follow this nice tutorial: https://businessbloomer.com/woocommerce-display-custom-product-badge/

I play around with this code for enable/disable scripts with a checkbox for a certain product:

...
add_action( 'wp_enqueue_scripts' , 'gfp_scripts' );
 
function gfp_scripts() {
global $product;
  if ( get_post_meta( $product->get_id(), 'load_scripts_checkbox', true ) ) { // If checkbox is enabled load scripts
    wp_enqueue_script( 'jquery' );
    ...
  }
}
... 

But it doesn’t work.

It gives this error:

Fatal error: Uncaught Error: Call to a member function get_id() on string in /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-content/plugins/google-fonts-preview/google-fonts-preview.php:68 Stack trace: #0 /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-includes/class-wp-hook.php(286): gfp_scripts(”) #1 /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #2 /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-includes/script-loader.php(1435): do_action(‘wp_enqueue_scri…’) #4 /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-includes/class-wp-hook.php(286): wp_enqueue_scripts(”) #5 /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #6 /home/u14701p11712/domains/webkusthosting.be/public_ in /home/u14701p11712/domains/webkusthosting.be/public_html/dev/wp-content/plugins/google-fonts-preview/google-fonts-preview.php on line 68
