Filter is missing?

[gorostas]

Hi,

based on this page ​https://make.wordpress.org/core/2020/01/29/lazy-loading-images-in-wordpress-core/ there is this filter - that I tried to hook on wp_set_image_loading_attr - but it's not working.

To be sure grep -r "wp_set_image_loading_attr" --include=*.php in web root returns nothing.. so - two things here:

• documentation is obsolete.
• functionality is crippled.

I needed this hook today (but surely there will be others) to be able to selectively (per image) turn lazy ON|OFF .. and wp_lazy_loading_enabled can't fit it because it's global.

Thanks, Kres

@gorostas Thanks for the report. I think the correct filter is ​wp_img_tag_add_loading_attr. Can you check and confirm please? If so we'll get the documentation corrected.

Wow @johnbillion

that one works like charm - thanks :)

I could update the page and also paste example for this dedicated page for this filter ​https://developer.wordpress.org/reference/hooks/wp_img_tag_add_loading_attr/ - but don't know exact github branch - if you send me I can do it :)

Thank

Hi, @gorostas! Thanks for offering to update the documentation 🙌🏻. In this case, it is a Core developer blog post that needs adjustment, not accessible via GitHub.

There is a User Contributed Notes section at the bottom of developer documentation pages where snippets are sometimes shared related to use of a particular function.

Thanks again for your report!

I've correct the original blog post. Thanks again for the report @gorostas.
