Render an asset svg file
  • Hey Folks,
    Is a way to render exactely like does Asset::js with false but for svg:
    Asset::js('logo.svg'), array(), 'svg', false); :

    output:
    <svg version="1.1" id="black_1_" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
    viewBo ...

    thanks

    Asset::instance()->add_type('svg', $rootpath-to-your-asset, function($images, $attr, $inline) {
        // your code to render the asset goes here...
    });

    You could have a look at the Asset_Instance class, render_img(), to see how that is done.
  • So I have just to extends Asset class with the new asset type, I look that.
    Thanks Harro

    That works too.
  • Hey Harro, on a basic test code:

    \Asset::instance()->add_type('svg', '/themes/josselin/img/', function($images, $attr, $inline) {
                $result = '<svg></svg>';
                return $result;
    });

    echo \Asset::svg('logo-inline.svg', array(), 'svg', false);
    or  echo \Asset::svg('logo-inline.svg');

    It return error: Call to undefined method Fuel\Core\Asset::svg()

    it was not supposed to create a Asset svg instance?
  • no wrorry I just need file_get_contents, I will setup on my path's theme
    thanks
  • No, it doesn't have a static interface, as it's created on the instance, not globally.

    \Asset::instance->svg('logo-inline.svg');

    should work. 

    Do you still have your Asset class extension? If so, you could add:

    /**
     * Provide a static interface to the default instance methods
     *
     * @param $method
     * @param $args
     * @return mixed
     * @throws \ErrorException
     */
    public function __callStatic($method, $args)
    {
    return call_user_func_array(array(static::instance(), $method), $args);
    }

    Can you test this for me? If that works, I can add it to the core class...
  • I added code to file: core/classes/asset/instance.php after construct

    and when I do:
    echo \Asset::svg('/themes/josselin/img/logo-inline.svg');

    It return:
    The magic method __callStatic() must have public visibility and be static

    I tried to replace with: public static function, no way, maybe I am wrong
  • No, add it to core/classes/asset.php, that provides the static interface.
  • yeah it works but with 'public static function' instead of 'public function'.

    Now I need to understand how return the content of my SVG file code on the page in this instance:

    \Asset::instance()->add_type('svg', '/themes/josselin/img/', function($images, $attr, $inline) {
    $result = file_get_contents($images);
    return $result;
     });
    echo \Asset::svg('logo-inline.svg');

    output: "Object of class Asset_Instance could not be converted to string"

    I dont understand the path, the file is in: http://josselin2.dev/themes/josselin/img/logo-inline.svg
    if its works it would like nice to calll asset through Theme like with css, js. :)
  • Yeah, it should be a static method, sorry.

     I don't see how given the examples the Asset_Instance() object could be returned?

    And your closure should return HTML, so the output in your initial question, and not a dump of an svg file.
  • in asset instance js has this code:

    protected function render_js($file, $attr, $inline) {
    ...
    if ($inline) {
    $result = html_tag('script', $attr, PHP_EOL.$file.PHP_EOL).PHP_EOL;
    }
    return $result;

    and with true $inline it return dump of js in html view

    I could not have the same beviahor? sort of:

    \Asset::instance()->add_type('svg', '/themes/josselin/img/', function($file, $attr, $inline) {
    result = html_tag('svg', $attr, PHP_EOL.$file.PHP_EOL).PHP_EOL;
    return $result;
    });

    Added the required code to the Asset class: https://github.com/fuel/core/commit/cc6096991c0811c75ea46f08a9762a5a4c40739d

    Tested with:

    \Asset::add_type('svg', 'assets/svg/', function($file, $attr, $inline) {
    // return the svg file
    return file_get_contents($file);
    });

    echo \Asset::svg('test.svg');

    which assumes you have test.svg in ./public/assets/svg.
  • awesome Harro !
