Edit History

Hello, I tried really hard to google or do it on my own, but I did not find a solution to my problem.


Version: Prestashop 1.7
Here is what I am trying to do: 
I crated a blog category inside Design > Pages that display blog articles.

I want the url of the blog article to be like this: mywebiste.com/blog/article-1

After I have done some research I found out that I must edit the Dispatcher.php and Link.php, so they currently look like this:

Dispatcher.php

        'cms_rule' => array(
            'controller' =>    'cms',
            'rule' =>        'content/{categories:/}{id}-{rewrite}',
            'categories' => array('regexp' => '[/_a-zA-Z0-9-\pL]*'),
            'keywords' => array(
                'id' =>            array('regexp' => '[0-9]+', 'param' => 'id_cms'),
                'rewrite' =>        array('regexp' => '[_a-zA-Z0-9\pL\pS-]*'),
                'meta_keywords' =>    array('regexp' => '[_a-zA-Z0-9-\pL]*'),
                'meta_title' =>        array('regexp' => '[_a-zA-Z0-9-\pL]*'),
            ),
        ),

and my Link.php looks like this:

 

    public function getCMSLink(
        $cms,
        $alias = null,
        $ssl = null,
        $idLang = null,
        $idShop = null,
        $relativeProtocol = false
    ) {
        if (!$idLang) {
            $idLang = Context::getContext()->language->id;
        }

        $url = $this->getBaseLink($idShop, $ssl, $relativeProtocol).$this->getLangLink($idLang, null, $idShop);

        $dispatcher = Dispatcher::getInstance();
        if (!is_object($cms)) {
            if ($alias !== null && !$dispatcher->hasKeyword('cms_rule', $idLang, 'meta_keywords', $idShop) && !$dispatcher->hasKeyword('cms_rule', $idLang, 'meta_title', $idShop)) {
                return $url.$dispatcher->createUrl('cms_rule', $idLang, array('id' => (int) $cms, 'rewrite' => (string) $alias), $this->allow, '', $idShop);
            }
            $cms = new CMS($cms, $idLang);
        }

        // Set available keywords
        $params = array();
        $params['id'] = $cms->id;
        $params['rewrite'] = (!$alias) ? (is_array($cms->link_rewrite) ? $cms->link_rewrite[(int) $idLang] : $cms->link_rewrite) : $alias;

        $params['meta_keywords'] = '';
        if (isset($cms->meta_keywords) && !empty($cms->meta_keywords)) {
            $params['meta_keywords'] = is_array($cms->meta_keywords) ? Tools::str2url($cms->meta_keywords[(int) $idLang]) : Tools::str2url($cms->meta_keywords);
        }

        $params['meta_title'] = '';
        if (isset($cms->meta_title) && !empty($cms->meta_title)) {
            $params['meta_title'] = is_array($cms->meta_title) ? Tools::str2url($cms->meta_title[(int) $idLang]) : Tools::str2url($cms->meta_title);
        }

        return $url.$dispatcher->createUrl('cms_rule', $idLang, $params, $this->allow, '', $idShop);
    }

I cant get it to work no matter what I try, any help is gladly appreciated!
Thanks!
