Question

我有一个幼虫集合，我试图让它显示不包含值的结果。

我知道$ data-＆gt;包含（键，值），它基本上需要与此相反。我试图在刀片模板中执行此操作，代码如此;

    @if(!$orders->contains('order_status', 'Complete'))

和

    @if($orders->contains('order_status', 'Complete') === false)

但都没有按预期工作。

任何想法或替代方法（如果可能的话，想尝试在刀片中保留逻辑）？

感谢

Answer 1

原来这只是一个逻辑错误as discussed in chat。

@if(!$orders->contains('order_status', 'Complete'))

这就是说，只有在order_status＆＃39;完成＆＃39;如果有任何订单不是＆＃39;完成＆＃39;＆＃34;。

而不是预期＆＃34;显示此项

Answer 2

我要添加一些内容来避免使!变得更漂亮：

@unless($orders->contains('order_status', 'Complete'))

Laravel集合不包含
