Problem with smarty cache - How to clear only css cache

[JParriki]

Hello community,

 

I would like to know if it is possible to clear only the css cache from a module.

 

I have a module with styles and javascript but without views (I only use the hookDisplayHeader on the module).

I only use it to make my own styles and javascript without have to touch any other css files.

 

The problem is that when I make a change, some users don´t see the change because they have the file on cache.

 

I tried to use the Cache class from prestahop but it doesn´t work,  I think I don´t use the class on right way.
 

Other thing that I tried, was to put on the htacces the following code, but it didn´t work.

 

 

<filesMatch "\.(html|htm|js|css|php)$">
FileETag None
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</filesMatch>
 

 

I also wrote on the main "index.php", that is on the root folder, this code:

 

 

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 1 Jul 2000 05:00:00 GMT"); // Fecha en el pasado

 

Anyone can help me?

 

PD: Sorry for my English

If the styles are already cached in the visitors browser, then you must wait for those to expire or physically clear that browser cache.  The alternative is to rename the modules css files which would force the visitor to download it

You can also switch between CCC enabled and disabled to regenerate cached files.

This would be true if he was referring to the server side cached files.  However he is referring to the client side cached style sheets

/**

public static function clearCache()
{
    $files = array_merge(
        glob(_PS_THEME_DIR_ . 'assets/cache/*', GLOB_NOSORT),
        glob(_PS_THEME_DIR_ . 'cache/*', GLOB_NOSORT)
    );

    foreach ($files as $file) {
        if ('index.php' !== basename($file)) {
            Tools::deleteFile($file);
        }
    }

    $version = (int) Configuration::get('PS_CCCJS_VERSION');
    Configuration::updateValue('PS_CCCJS_VERSION', ++$version);
    $version = (int) Configuration::get('PS_CCCCSS_VERSION');
    Configuration::updateValue('PS_CCCCSS_VERSION', ++$version);
}

This with some adjustments should fit anyones needs 😁
