Tired of Refreshing Your CSS Everytime You Make A Change?
So am I. I make changes a lot live on the server (using the Web Dev Toolbar), and I have to hard-refresh every time I make a change. Doesn’t sound like a big deal, but it cuts down on valuable time that could be done… well, not refreshing a page. There is a way; versioning your CSS file. The upside: it makes changes go live automatically without having to clear the cache. The downside: it’s difficult to do, because the correct way to do it is by adding v=XXX manually every time you make changes.
Unless… you can find a way to do it automatically. And Mark Jaquith has done just that.
<link rel="stylesheet" href="<?php bloginfo('template_url'); ?>/style.css?v=<?php echo filemtime(TEMPLATEPATH . '/style.css'); ?>" type="text/css" media="screen, projection" />
So what does the ‘filemtime’ function do? From the PHP website:
This function returns the time when the data blocks of a file were being written to, that is, the time when the content of the file was changed.
So everytime you change the file, the new change time gets parsed in using PHP and you’re able to have a new version every time.
Thanks to Mark for this great (and really clever) tip!
