Cannot enqueue custom js via php

Hi there,

your wp_enqueue_script arguments are incorrect, see here for an example of the correct method:

https://developer.wordpress.org/reference/functions/wp_enqueue_script/#comment-274

Hello David,

why are my arguments incorrect? They are the same as in the example you provided, but for the path: get_stylesheet_directory_uri() poins to the child theme root folder, where my file is located, while get_template_directory_uri() as in the example points to the parent theme root folder.

Try this method:

add_action( 'wp_enqueue_scripts', 'add_my_script' );
function add_my_script() {
    wp_register_script(
       'theme_js', 
       get_stylesheet_directory_uri() . '/js/davide_scripts.js', 
       array('jquery') 
    );

    wp_enqueue_script('my-accordion-script');
}

Thanks, this works!

Since now both options are available (wp_enqueue_scripts and src hook in wp_head), which one is better? Consider I only need the script for one post category, and the hook allows me to load it only for that category.

You can set a condition for add_action( 'wp_enqueue_scripts', 'add_my_script' ); so it only loads on certain category.

Example: (For single posts under category "test_category")

if(is_singular() && in_category('test_category')){
add_action( 'wp_enqueue_scripts', 'add_my_script' );
}

Lovely, thanks a lot! 😀

Edit: for future reference, the provided code did not actually work: I had to put the if statement inside the function to make it work (https://wordpress.stackexchange.com/questions/310865/is-singular-and-is-home-not-working)

add_action( 'wp_enqueue_scripts', 'add_my_script' );

function add_my_script() {
	if(is_singular() && in_category('Recensioni')) {
		wp_register_script(
			'review_grid_js', 
			get_stylesheet_directory_uri() . '/js/review-grid.js', 
			array('jquery') 
		);

		wp_enqueue_script('review_grid_js');
	}
}

Nice one. Glad you got it sorted. :)

Hello all, I may tie here briefly.

I just can't get my script to embed. The script is in the child-theme-folder under js/voting.js

Here is my code:

// Funktion zum Enqueue der Javascript-Datei

add_action( 'wp_enqueue_scripts', 'add_my_script' );

function add_my_script() {
    wp_register_script(
       'voting_js', 
       get_stylesheet_directory_uri() . '/js/voting.js', 
       array('jquery') 
    );

    wp_enqueue_script('voting_js');
}

What am I doing wrong? Am I missing something?

Hi there,

try just enqueueing your script:

function add_my_script() {
    wp_enqueue_script( 'voting_js', get_stylesheet_directory_uri() . '/js/voting.js', array('jquery'), '1.0.0', true );
}
add_action( 'wp_enqueue_scripts', 'add_my_script' );

Hi David,

I have now adapted the code again. Also I have completely copied a code that I have running on another site. The page vehemently refuses to load my Custom.js. I don't know what the problem is. Maybe you can have a look. How can I write private content in the forum?

Never mind! I spotted the problem!

Glad to hear that!
