#35648 new defect (bug)

the_post_thumbnail sets srcset with http protocol

Reported by: javiertoledos's profile javiertoledos Owned by:

Severity: normal Version: 4.4
Component: Media Keywords: reporter-feedback https bulk-reopened
Focuses: Cc:


We have a wordpress site that uses https always, when we use the_post_thumbnail, it returns HTTPS for the SRC attribute but it returns HTTP values for the SRCSET attribute. This is not a duplicate of #28261 or #15928 because this only happens on the srcset attribute.

We had to do this filter in order to do a quick patch:

function fix_srcset_https_thumb_images ($html) {
    if ( is_ssl()) {
        $html = str_replace('http://','https://',$html);
    return $html;

add_filter('post_thumbnail_html','fix_srcset_https_thumb_images') ;

@javiertoledos Can you please let us know how you've forced the site to HTTPS only?

Are you using any SSL constants? Plugins? What's your WordPress URL / Site URL set to (Settings -> General)? Is the media URL set to anything under Settings -> Media?

Following the code trail: For src, comes from wp_get_attachment_image_src <- image_downsize <- wp_get_attachment_url where the url is fixed using set_url_scheme. This doesn't happen for srcset, which pulls its base url straight from _wp_upload_dir_baseurl.
Presumably, this could be fixed just after this point (search for $image_baseurl in wp_calculate_image_srcset), in a similar manner. Might be worth investigating putting it lower down in the root wp_upload_dir, though?

Its still relevant - I can replicate on Wordpress 5.1.1
