Use is impossible

[CaptainJojo]

I use your Bundle but is not functionnal, I have variable with node.value and node.filter in my twig. I use node.value|apply_filter(node.filter) I have an error, because not find template why ?

[marcj]

what is the exact error?

Same error here, and I also can't understand how it should work. Did you test it? The twig environment is trying to load a file, since there is no string loader registered by default. Since there is no template file, twig can't load it and fails with:

Unable to find template "{{ apply_filter_0122b4c2c01ee1c698ecc309d2b8eb5a|upper }}"

Maybe you got newer Twig versions where it isn't possible anymore. In tests the base stuff is covered https://github.com/marcj/twig-apply_filter-bundle/blob/master/Tests/BaseTest.php

Possible, maybe it's Symfony related. Can't tell you. The workaround is pretty easy. Just backup the current loader on the environment using getLoader() and set the new one to a Twig_String_Loader (Twig_Loader_String?) instance. Now you're able to load strings as templates. After loading, you can reset the loader to the previous one using setLoader().

Twig_String_Loader is marked as deprecated. So using that would probably be a bad idea. I did manage however to use $env->createTemplate($template) instead of loadTemplate at which point the script kept executing. Downside probably would be that a new cache template is created time after time.

Hi,

I propose to you a solution using the Twig_loader_FileSystem. This solution is working on symfony 2.7 with the advantage to not generate a lot of supplementary cache. What do you think about this?

/**
     * Apply twig filter of the environment by using theirs names (as string).
     *
     * Exemple: {{ value|apply_filter("upper") }}
     *
     * @param \Twig_Environment $env
     * @param array $context
     * @param $value
     * @param $filters
     *
     * @return string
     */
    public function applyFilter(\Twig_Environment $env, $context = array(), $value, $filters)
    {

        $fs = new Filesystem();

        //set the needed path
        $template_dir_path = $env->getCache().'/apply_filter';
        $template_file_name = $filters.'.html.twig';
        $template_path = $template_dir_path.'/'.$template_file_name;

        //create dir for templates in twig cache
        if(!$fs->exists($template_dir_path))
            $fs-mkdir($template_dir_path);

        if(!$fs->exists($template_path))
        {
            //write the new template if first call
            $template = sprintf('{{ value|%s }}', $filters);
            file_put_contents($template_path,$template);
        }

        //store the old loader (not sure that is necessary)
        $old_loader = $env->getLoader();

        //use file loader
        $loader = new \Twig_Loader_Filesystem($template_dir_path);
        $env->setLoader($loader);

        $rendered = $env->render($template_file_name,array("value" => $value));

        //reload the previous loader
        $env->setLoader($old_loader);

        return $rendered;
    }

Same error with sf 2.7

Same error with sf 2.8 Not working, not testing!

I highly doubt this bundle is maintained any longer.
