How to add additional http header to a wp_error rest response

WP_REST_Response extends WP_HTTP_Response class, which has a header() method for setting headers. Using the rest_request_after_callbacks filter should allow setting the header, but will need to duplicate the functionality of WP_REST_Server->error_to_response(), which at time of writing calls rest_convert_error_to_response(), so that’s easy enough. Here’s what I think this will end up looking like (untested). add_filter( ‘rest_request_before_callbacks’, static … Read more

Content Security Policy blocking images from installed plugins’ popup info window, as they are from external domains – global fix?

The answer, as mentioned in a comment by @JacobPeattie, was to add the domains to my .htaccess file where I am setting the CSP Headers, (turns out most plugins’ “View Details” link loads images from ps.w.org, which I just learned). A few other plugins loaded images from other domains, so I also added each of … Read more

Why is there a bunch of WordPress HTML code in my browser CSV download?

wp_redirect problem using code snippets

You can’t use wp_redirect or make HTTP redirects from inside a shortcode, redirects must happen before HTTP headers are sent out, before any HTML is sent to the browser, so shortcodes will always be too late. So I looked around and I believe the problem is that some content is sent to the browser before … Read more

How do you modify HTTP response headers on feed/?

If you just want to change the Content-Type header, then the feed_content_type filter can indeed be used for that purpose. (If your code isn’t changing the header, then another code might have overridden that header, so you can try using a lower priority for your filter callback) But there’s another filter hook you can use, … Read more
