I need WP to show an embedded representation of a url such as http://domain.com/1121 using oembed.
I have setup http://domain.com/1121 with a discovery link:
<link href="http://www.domain.com/generator/oembed/?url=http%3A//domain.com/1121" rel="alternate" type="text/xml+oembed" />
I’m aware that WP no longer automatically discovers embeddable URLs, so I installed enable-oembed-discovery plugin to re-enable this feature.
I have monitored my apache logs and confirmed that WP does hits the link to discover – so I guess the enable-oembed-discovery plugin works, but the URL is NEVER converted.
I even wrote a plugin to whitelist my custom URL (really should not be needed since enable-oembed-discovery plugin should enable auto-discovery, but what the heck):
add_action( 'init', 'my_oembed_provider' );
function my_oembed_provider() {
wp_oembed_add_provider( 'http://domain.com/*', 'http://www.domain.com/generator/oembed/', false);
}
and still nothing.
The API endpoint (http://www.domain.com/generator/oembed/) is hard coded to generate the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<OEmbed>
<type>rich</type>
<width>400</width>
<height>342</height>
<html><![CDATA[<b>HELLO WORLD FROM OEMBED </b>]]></html>
</OEmbed>
The API endpoint sends the right content-type header (header("Content-type: text/xml");) as required by the oembed spec
The user adding the post has admin privileges and therefore is allowed unfiltered_html
I’m out of ideas and at wit’s end. What am I missing?
