Method orWhere does not exist. Laravel 5.3

Question

BadMethodCallException in Macroable.php line 74: Method orWhere does not exist.

    $category = $categories->where('Node_ID', (explode('.', $cat{$title_id})[0]))
        ->orWhere('Node_Path', $cat->{$category_name})
        ->first();

If I try without "orWhere" works, if I use it, throws an Error. Someone knows where is the mistake?

Solution

You are trying to use orWhere on collections, thats why its showing you the error. You should use this on model like this (taking Category as a Model):

$category = Category::where('Node_ID', (explode('.', $cat{$title_id})[0]))
                     ->orWhere('Node_Path', $cat->{$category_name})
                     ->first();

See Laravel Docs for orWhere()

Hope this helps!
