Prestashop 1.6 - Mettre jquery.min.js sur le cdn de Google

Nous allons créer un override Controller.php dans /override/classes/controller et y mettre ce code.

<?php

    abstract class Controller extends ControllerCore
    {

        /*** All other previous overrides here ***/

        /**
         * Use Google's CDN to host jQuery
         * @param string  $version  Version of jQuery to include
         * @param string  $folder   Not used in this override
         * @param boolean $minifier Use minified version?
         */
        public function addJquery($version = null, $folder = null, $minifier = true) {

        $this->addJS(Media::getJSPath(Tools::getCurrentUrlProtocolPrefix() . 'ajax.googleapis.com/ajax/libs/jquery/' . ($version ? $version : _PS_JQUERY_VERSION_) . '/jquery'.($minifier ? '.min.js' : '.js')));
		$this->addJS(Media::getJqueryPath($minifier));

        }
    }

Nous créons l'override de Media.php que nous placons dans /override/classes

<?php

    class Media extends MediaCore
