How to add a function to functions.php?

Resolved

(@codex22)

Hello dear wordpressoholics,
I am stuck with a problem. I want to add the following code to my functions.php:

add_action('wp_enqueue_scripts', 'mh_superfish');
function mh_superfish() {
	if(!is_admin()) wp_enqueue_script('superfish', template_url( 'js/superfish.js', __FILE__ ), array('jquery'), '1.4.8', TRUE);
	if(!is_admin()) wp_enqueue_script('superfish-args', template_url( 'js/superfish_args.js', __FILE__ ), array('jquery'), '1.4.8', TRUE);
}

But every time I try something, I always got a fatal error message. Please help! Thank you!

I did, and it will work, if I can change this code:
plugins_url( 'js/superfish.js', __FILE__ ), array('jquery'), '1.4.8', TRUE

so the script will look in the theme directory.

That line by itself doesn’t mean anything, It’s incomplete.

```
add_action('wp_enqueue_scripts', 'mh_superfish');
    function mh_superfish() {
	if(!is_admin()) wp_enqueue_script('superfish', plugins_url( 'js/superfish.js', __FILE__ ), array('jquery'), '1.4.8', TRUE);
	if(!is_admin()) wp_enqueue_script('superfish-args', plugins_url( 'js/superfish_args.js', __FILE__ ), array('jquery'), '1.4.8', TRUE);
    }
```
That’s the complete code.

@codex22 That function is currently looking for those scripts in the plugins directory. It sounds to me like you want to move those scripts to your theme directory somewhere (maybe in a folder called js or something) and use get_stylesheet_directory_uri() in the function above instead of plugins_url(). This way it will look for those scripts in your theme’s newly created js directory. Does that make since?

@esmi Am I on the right track with this?

Hi,
this will only go to the themefolder, but won’t go into the js folder.

Because your function mh_superfish already exists, it cannot redeclare the function mh_superfish, you should change it’s name , for example
```
add_action('wp_enqueue_scripts', 'my_mh_superfish');
function my_mh_superfish() {
	if(!is_admin()) wp_enqueue_script('superfish', template_url( 'js/superfish.js', __FILE__ ), array('jquery'), '1.4.8', TRUE);
	if(!is_admin()) wp_enqueue_script('superfish-args', template_url( 'js/superfish_args.js', __FILE__ ), array('jquery'), '1.4.8', TRUE);
}
```

If I use this code, I get an error message:
Fatal error: Call to undefined function template_url() in C:\xampp\htdocs\wordpress\wp-content\themes\my_theme\functions.php on line 16

Try this
```
add_action('wp_enqueue_scripts', 'my_mh_superfish');
function my_mh_superfish() {
	if(!is_admin()) wp_enqueue_script('superfish', get_template_directory_uri(). '/js/superfish.js', array('jquery'), '1.4.8', TRUE);
	if(!is_admin()) wp_enqueue_script('superfish-args', get_template_directory_uri().'/js/superfish_args.js', array('jquery'), '1.4.8', TRUE);
}
```

this will only go to the themefolder, but won’t go into the js folder.

Correct, but with the rest of the string you get to the js folder. 🙂

@hoosoft has the right idea.
