Get image of category menu


Recommended Posts

Hi,

I've created a mega menu for my website. I've also added an image to the "menu thumbnail" input.

So this is where the file is located : http://mywebsite.com/img/tmp/category_13-0_thumb.jpg?time=1585727749

I'm overriding the ps_mainmenu.php file in order to add some data to my item menu.

 

I'm trying to get the image thanks to this, but it's always returning an empty array :

$files = scandir(_PS_TMP_IMG_DIR_);
//        $files = scandir(_PS_CAT_IMG_DIR_);

if (count(preg_grep('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $files)) > 0) {
            foreach ($files as $file) {
                if (preg_match('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $file) === 1) {
                    $image_url = $this->context->link->getMediaLink(_THEME_CAT_DIR_.$file);
                    $thumbnail[] = $image_url;
                }
            }
        }

 

I'm working on PS 1.7.
