Loading scripts in WordPress

[Dave Navarro]

At what point does WordPress process short codes in content?

I have a short-code I created for displaying a custom Google map and I
only want to load the necessary javascript files if the short-code is
used on a page. Are short-codes processed before the headers are sent
to the browser or after?

Thanks!

Shortcodes are parsed at the the_content filter.

That said: you can simply call wp_enqueue_script() inside your shortcode
callback, which will ensure that your scripts only get enqueued when the
shortcode is parsed.

Thank you for your quick response. I'll take a look at that.

That's interesting Chip. I thought that would have been too late.
Isn't it that when the "the_content()" is running, wp_head action hook has
already been executed?

If you call wp_enqueue_script() after the_header() then the script will be
enqueued in the footer. Dependencies will work as expected. (This wasn't
always the case, it was added in 3.3)
