Header Injection

How to inject a script into the glober header. I entered few lines in the header.php, which is not working. Please help

Hi, proper way to enqueue script is from functions.php file (theme folder root). You can read more about it on WP.org.

If you open Intro theme functions.php file, find comented line `/**

  • Enqueue scripts and styles.
    */` and place yours after (you will see lot of wp_enqueue_script lines)

Better way would be this:

function add_custom_dimi_scripts() {
	wp_register_script('dimi_custom_jquery', get_template_directory_uri() . '/js/custom.js', array('jquery'), '1.0', true);

It is just an example of custom.js script which is jQuery dependent. In this example custom.js script is located in theme folder > js > custom.js (so you must save your script there).

Of course consider using child theme for modifications of this kind.

I would like to inject below code. How can i make it? Thanks!

<script src="//load.sumome.com/" data-sumo-site-id="c5eac674a593cc813fd70bc5220724f2132e79e954050471d5e825aa20581be2" async="async"></script>

Oh, for that. It should work by adding code to header.php just above wp_head();

Also you can use some plugin like Insert Headers and Footers.
