Since cakephp 1.3, build-in css compression has stopped working. at least for me. however, it’s very easy to get it working again.
Step 1:
grab csspp from here and put it in your vendor directory so it looks something like this (app/vendors/csspp/csspp.php)
Step 2:
in your core.php file in app/config, uncomment Configure::write(‘Asset.filter.css’, ‘css.php’);
Step 3:
in your css.php under app/webroot, modify make_clean_css function so that it looks something like this
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
function make_clean_css($path, $name)
{
App::import('Vendor', 'csspp' . DS . 'csspp');
$data = file_get_contents($path);
$csspp = new csspp($name,'');
$output = $csspp->process();
$ratio = 100 - (round(strlen($output) / strlen($data), 3) * 100);
$output = " /* file: $name, ratio: $ratio% */ " . $output;
return $output;
}
and that should be it. if it doesnt work for some reason,
change line 82 in your app/webroot/css.php to
if (file_exists($cachepath) && 0)
so you won’t be looking at cached file when u debug.
