php - Enqueue sripts and styles only if function is called

I'm using a function to display a gallery and I need to load its JS/CSS only if the gallery function is called. Both functions are in the custom plugin.

I have now the first function to enqueue scripts and styles and function itself:

function gallery_assets() {
            $upload_dir = wp_get_upload_dir();
            wp_enqueue_style('flex-gallery', trailingslashit( $upload_dir["baseurl"]).'gallery-assets/css/flex-gallery.css');

            wp_enqueue_script('flex-gallery-jquery', trailingslashit( $upload_dir["baseurl"]).'gallery-assets/js/jquery.min.js');
            wp_enqueue_script('flex-gallery', trailingslashit( $upload_dir["baseurl"]).'gallery-assets/js/flex-gallery.js');
            } 
add_action( 'wp_enqueue_scripts', 'gallery_assets', 10);
function portfolio_gallery () {}

My question is: How I can execute gallery_assets() from portfolio_gallery()?

Thank you!

Instead of two functions, just put the gallery assets code inside of the portfolio gallery function.

Or nest it. Nesting is kinda ugly though.

Unfortunately, you haven't given any indication as to how portfolio_gallery() is executed. Is it called from another function/location? Or is it hooked to something?

It's actually more than likely that you don't need to execute gallery_assets() from portfolio_gallery(). If portfolio_gallery() runs in the body (such as displaying content), gallery_assets() it would already have executed. You've hooked it to the wp_enqueue_scripts action, and as written, it will execute in the head.

This page in the Codex has a general list of actions and the order they come in.
