Hi mate,<\/p>\n

I am facing an issue regarding different custom post types in different blogs. Here is my stackoverflow question regarding the issue itself: https:\/\/stackoverflow.com\/questions\/64753068\/how-to-correctly-determine-whether-a-post-type-is-active-in-a-given-blog-in-a-wo?noredirect=1#comment114489656_64753068<\/p>\n

Now, as it doesn’t seem to be possible to safely determine whether post-types are active in other blogs, I was wondering if you could add an option for us developers to filter the hreflang output, so we can check whether a tag should be printed or not depending on our own setup. <\/p>\n

Specifically, a filter in MslsOutput.php<\/code> in method get_alternate_links<\/code> would we great. Maybe just after $url = $blog->get_url($options);<\/code> in the foreach loop, something like:<\/p>\n

$url = apply_filters('mlsl_output_url', $url, $blog);<\/code><\/p>\n

And – or maybe event better – also in the MslsBlog::get_permalink($options)<\/code> method as the blog id is actually set to the respective blog there, just after<\/p>\n

$url = $options->get_permalink($this->get_language());<\/code>
\nalso add a filter so you can return null for the URL if desired<\/p>\n

$url = apply_filters('mlsl_blog_permalink', $url, $this, $this->obj->userblog_id);\n<\/code><\/pre>\n
Then we can simply return null if I don’t want a specific hreflang tag to be printed. At the current point, we only can<\/p>\n
remove_action('wp_head', ['lloc\\Msls\\MslsPlugin', 'print_alternate_links']);<\/code><\/p>\n
But this will avoid any tags from being printed, also the x-default. <\/p>\n
If there is another way you would approach this issue feel free to point it out.<\/p>\n
Thanks for your support!
