I have this helper class file (currently reachable):


require_once dirname(__FILE__).'/securimage/securimage.php';

class Milyuncarros_Mobile_Helper_Captcha extends Mage_Core_Helper_Abstract
    public function check($value)
        $securimage = new Securimage();
        return $securimage->check($value);

    public function show($ns)
        $img = new Securimage();
        if ($ns) $img->setNamespace($ns);
        $img->show();  // outputs the image and content headers to the browser

I get this error:

Fatal error: require_once(): Failed opening required '/home/carros/public_html/includes/src/securimage/securimage.php' (include_path='/home/carros/public_html/includes/src:.:/usr/lib/php:/usr/local/lib/php') in /home/carros/public_html/includes/src/Milyuncarros_Mobile_Helper_Captcha.php on line 3

As you can notice, there's no /app directory in the failing path. But my helper class (and the needed securimage folder) is located at /app/code/local/Milyuncarros/Mobile/Helper.

Why is it failing at such wrong path?


This is due to compilation enabled. Use the following lines for require_once:

require_once BP.DS.'securimage'.DS.'securimage.php';

BP and DS are the pre-defined constants in Mage.php, BP is base path of install while DS is directory separator.

Hope this will resolve the issue even if compilation enabled.

  • yes, figured it yesterday :). expand the answer (i.e. what values are BP and DS fetched from). – Luis Masuelli Jul 16 '14 at 14:12

Try Mage::getModuleDir('', 'Your_Extension'); and concat Helper. Check this question to see some more options about folders shortcuts.

  • found the error: the helpers are compiled, and the compiled files are sent to such "wrong" folder. – Luis Masuelli Jul 15 '14 at 22:21
  • Its a good practice to use this either way since Magento will detect the folders for the includes. – mbalparda Jul 15 '14 at 22:22
