Removing Do Not Track for oembeds

@filipeos

WordPress cached embed data responses in the postmen table, it’s likely the at the function you are calling is being bypassed and cached data are being used. Try this query in PHPMyAdmin and check the stored data, I bet the ‘dot’ tags are in there.

SELECT * FROMwp_postmetaWHEREmeta_keyLIKE '%_oembed%'

You can delete those keys to force a refresh and check that your filter is working.

Hi,

I got:

[25-Apr-2020 12:23:52 UTC] PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function dl_oembed(), 1 passed in /home4/choseni1/public_html/XXX/wp-includes/class-wp-hook.php on line 289 and exactly 3 expected in /home4/choseni1/public_html/XXX/wp-content/themes/powerlift-child/functions.php:151

for the code:

function dl_oembed ( $provider, $url, $args ) {
  if ( strpos( $provider, 'vimeo.com' ) !== false)
     $provider = remove_query_arg( 'dnt', $provider );

  return $provider;
}
add_filter( 'oembed_fetch_url', 'dl_oembed' );

Yes, that code would be incorrect.

This would work:

function dl_oembed ( $provider, $url, $args ) {
  if ( strpos( $provider, 'vimeo.com' ) !== false)
     $provider = remove_query_arg( 'dnt', $provider );

  return $provider;
}
add_filter( 'oembed_fetch_url', 'dl_oembed', 10, 3);

The missing 10,3 would be the problem.
