WordPress 4.7 custom background image bug & workaround

If you encountered this bug but are not using Autoptimize, leave a comment below or contact me here. Your info can help understand if the regression has an impact outside of Autoptimize as well!


Gotta love Sarah, but there’s a small bug in Vaughan’s (WordPress 4.7) that breaks (part of the CSS) when Autoptimized. If you have a theme that supports custom backgrounds (e.g. TwentySixteen) and you set that custom background in the Customizer, the URL ends up escaped (well, they wp_json_encode() it actually) like this;

body{background-image: url("http:\/\/localhost\/wordpress\/wp-content\/uploads\/layerslider\/Full-width-demo-slider\/left.png");}

Which results in the Autoptimized CSS for the background-image being broken because the URL is not recognized as such. The bug has been confirmed already and the fix should land in WordPress 4.7.1.

If you’re impacted and can’t wait for 4.7.1 to be released, there are 2 workarounds:
1. simple: disable the “Aggregate inline CSS”-option
2. geeky: use this code snippet to fix the URL before AO has a change to misinterpret it;

add_filter('autoptimize_filter_html_before_minify','fix_encoded_urls');
function fix_encoded_urls($htmlIn) {
	if ( strpos($htmlIn,"body.custom-background") !== false ) {
		preg_match_all("#background-image:\s?url\(?[\"|']((http(s)?)?:\\\/\\\/.*)[\"|']\)?#",$htmlIn,$badUrls);
	  	if ($badUrls) {
			foreach ($badUrls[1] as $badUrl) {
				$htmlIn = str_replace($badUrl, stripslashes($badUrl), $htmlIn);
			}
		}
	}
  	return $htmlIn;
}

Music from Our Tube; James Bittersweet Lewis Trio

Just picked up on Worldwide FM; James Brandon Lewis Trio featuring Anthony Pirog and Nicholas Ryan Gant (aka @ghetto_falsetto). Kind of mellow-y, which I’m not always into, but duet of Lewis’ tenor-sax and the Gant’s falsetto scatting makes for a great mix, keeping the feeling fresh and real.

Watch this video on YouTube.

And if you want to something more in-your-face; have a go at “No Filter” by the same trio. Just tenor-sax, bass & drums, but you’ll be headbanging as if you were on the front-row of a metal-festival.
