Yes, it doesn’t work. It reverts to the one in the settings.

Okay, thank you that helps a lot. Is there a button_text option?

Update: After some experimentation I find that in fact this can be done very simply by using a custom template.

The lightbox popup windows are grabbing the title attribute set on the image. We have to insert and parse the shortcode with do_shortcode in the title and wrap it in esc_attr().

Here’s a pastebin of the working template.

Okay, thanks, feature request added.

I figured it out:

if (class_exists('EM_Events')) {
	$events = EM_Events::get( array('scope' => 'future' , 'limit'=>5) );
                 foreach($events as $EM_Event){
		      $EM_POSTID[]= $EM_Event->output('#_EVENTPOSTID');
               }

Per the post above the only way I can see to customize the header is to unhook the function and rehook your own version.

Okay, I got this to work by unhooking the interface_headercontent_details function and hooking in my own. I had the priority wrong in my first attempt.

//first remove the original function

function remove_interface_header_details() {
	remove_action( 'interface_header', 'interface_headercontent_details', 10 );
}
add_action('interface_header','remove_interface_header_details' , 9 );

Then copy and paste the entire interface_header_content_details function and action hook from header-extensions.php into the child theme functions.php. Rename the function and action hook and make your edits:

add_action( 'interface_header', 'my_interface_headercontent_details', 10 );
function my_interface_headercontent_details() {
PASTE THE CUSTOMIZED FUNCTION HERE. The main HTML structure is at around line 835.
