Invalid argument supplied for foreach() in /var/www/html/app/code/Ves/Megamenu/Model/Config/Source/StoreCategories.php on line 284

Question

I have this error when I add special characters to menu or categories like "&" It's from module Ves Megamenu.

Warning: Invalid argument supplied for foreach() in /var/www/html/app/code/Ves/Megamenu/Model/Config/Source/StoreCategories.php on line 284

Warning Line:

$categoriesTrees = $this->getCategoriesTree();
foreach ($categoriesTrees as $category) {
    $this->generatCategory($category);
}

Answer 1

Solutions was to change this line to:

$categoriesTrees = $this->getCategoriesTree();
if(is_array($categoriesTrees)){
   foreach ($categoriesTrees as $category) {
       $this->generatCategory($category);
   }
}

Now I can use "&" or "/" in categories names, without crashing the site.
