Relative CSS paths are wrong

[wazum]

This issue did already exist in the forge and bitbucket tracker, but was never fixed.
Now I changed to the recent version and had to adapt my patch.

Example:
in the CSS file generated by TYPO3 there's path like ../../../typo3conf/ext/my_ext/Resources/Public/fonts/myfont.xxx and the problem is that your extension passes the content of the file to the $minifier->add method, which results in appending another ../../.. in front of the already correct relative paths (because the source is missing).
The solution is to write the output of compressCss to a file and pass the file name to $minifier->add, then the source path is correctly determined by minifier and not changed.

Here's my local patch:

+++ Classes/Minifier.php
@@ -121,7 +121,8 @@
             $minifier = new $minifierClassName();
             if ($type === self::TYPE_STYLESHEET) {
                 $minifier->setImportExtensions([]);
-                $minifier->add($this->compressCss(file_get_contents($config['file'])));
+                file_put_contents($pathSite . 'tmp' . $targetFilename, $this->compressCss(file_get_contents($config['file'])));
+                $minifier->add($targetFilename);
             } else {
                 $minifier->add($config['file']);
             }

See vendor/matthiasmullie/minify/src/Minify.php:89 for details on how the key is generated and then used in the execute method vendor/matthiasmullie/minify/src/CSS.php:301 as $source variable to determine the correct path.

Hi, thanks for you issue. I've recently used EXT:min in a project including fonts and there I had no issues.

When your CSS is located in Resources/Public/Css/ and your font in Resources/Public/fonts you can simply address the font in CSS like this:

src: url("../fonts/my-font-regular.eot");

---

Also I'm suspisious that your approach really works, because when you create the $pathSite . $targetFilename file on your own, minifier will not minify it anymore (see condition in line 129) https://github.com/a-r-m-i-n/min/blob/master/Classes/Minifier.php#L129). Only the additional CSS compression will be applied to your CSS, then.

@a-r-m-i-n thanks, the same file name is a mistake, point taken, the rest is still valid, but maybe you have an idea how to solve it:

• I already have the ../fonts/… path in my source CSS files
• but when TYPO3 concatenates the CSS files

    page.config {
        compressCss = 1
        concatenateCss = 1

• it uses a method \TYPO3\CMS\Core\Resource\ResourceCompressor::cssFixRelativeUrlPaths which changes the paths to ../../../something/…
• which leads to the problem described above
  I don't know how you circumvent this in your projects, but would be nice to learn

Hey. I'm currently working on #2 and I think I know where the problem is. When you concatenate css files, TYPO3 is fixing the relative links, because the location of the actual called file moved to typo3temp/assets/compressed

When min is doing the same, the file paths are not getting adjusted. Need to investigate further, but it looks promising. Now, I'm on your page ;)

@wazum I think I got it :) Could you please test with the latest master? Thank you

@a-r-m-i-n thanks for version 2.1.0. The relative css paths of fonts in a compressed file are working now, but not if you already use the composer-installer v4 package with TYPO3 11, which has a different folder structure of public assets.

Thanks for your response. I think this worth a dedicated issue.
