如果有人能帮我解决这个问题,那就太棒了,我真的不知道如何解决它,而且我一直在绞尽脑汁(以及书籍和互联网)一段时间,却没有真正了解我需要做什么。我无论如何都不是程序员,纯粹是自学的,所以如果看起来很容易,请接受我的道歉。我已经为一个梦幻联赛足球网站创建了一个数据库,并获得了对结果和表格的正确查询,我只想添加一个查询,显示经理每周的结果,以及从中哪些球员为这些经理得分(没有经理的球队拥有相同的球员),例如:
(表头:周 > 经理 > 支持 > 反对 > 得分手) 2 Manager1 3-0(球员 a 1,球员 b 2) 2 Manager2 1-2(球员 f 1) 2 Manager3 4-1(球员 g 2,球员 x 2)
我正在使用大量的连接来获得我的结果,并且一直在尝试使用嵌套的 foreach 循环,我认为我需要做一个单独的 foreach 循环来遍历每个得分球队的任何球员(即从球员名单中拉出目标大于 0),但结果好坏参半 - 我不需要!
这是我的代码,从索引控制器到显示 foreach 循环的 html。如果有人可以提供帮助或有任何想法,我将不胜感激。
