Jupiter theme already had body_class instead of body_top
Thanks for the tip. What does the number 10 do in this function?
add_action( 'wp_head', 'add_gtm_head', 10 );
Just wanted to say:
if you leave the add_action as priority 10 (see the comments by tokyographer and raulfunkie above), the script is placed halfway down the section; I changed my priority to 1 and the script was placed immediately after the last tag in the section: exactly where I wanted it and, probably, where it 'shouldl' go!
Thanks very much for this
Change line 32 to:
add_action( 'wp_body_open', 'add_gtm_body' );
To make the above work, the header.php file needs to be updated by adding:
No need to. Better to use hooks in WP template.
wp_head ( https://developer.wordpress.org/reference/hooks/wp_head/ )
wp_body_open ( https://developer.wordpress.org/reference/hooks/wp_body_open/ )
@tokyographer It adds priority to the script to it executes before anything else.
