问题描述
我想在 $items 数组中添加新元素,出于某些原因我不想使用连接.
I want to add new element in $items array, I don't want to use joins for certain reasons.
$items = DB::select(DB::raw('SELECT * FROM items WHERE items.id = '.$id.' ;')); foreach($items as $item){ $product = DB::select(DB::raw(' select * from product where product_id = '. $id.';' )); $item->push($product); }
我该怎么办?
推荐答案
看起来一切都正确 根据 Laravel 文档,但你有一个错字
It looks like you have everything correct according to Laravel docs, but you have a typo
$item->push($product);
应该
$items->push($product);
push 方法将一个项目追加到集合的末尾:
push method appends an item to the end of the collection:
我还想认为您正在寻找的实际方法是 put
I also want to think the actual method you're looking for is put
$items->put('products', $product);
put 方法设置集合中给定的键和值
put method sets the given key and value in the collection
