Hi,

I want to change the links from hreflang on cs cart before the display, in the SEO addon is this function:

fn_seo_dispatch_before_display
where are set the hreflangs link.
How can i change this function to return my links?

Use the same hook in the My changes module to override the seo_alt_hreflangs_list array

But the function has no hooks.

But the function has no hooks.

This function already uses default hook called before_display
